I/O port access is implemented on Itanium by reading and writing to a
special region in memory. To hide details and avoid misaligned memory
accesses, a process did I/O port reads and writes by making a MD system
call. There's one fatal problem with this approach: unprivileged access
was not being prevented. /dev/io serves that purpose on amd64/i386, so
employ it on ia64 as well. Use an ioctl for doing the actual I/O and
remove the sysarch(2) interface.
Backward compatibility is not being considered. The sysarch(2) approach
was added to support X11, but support for FreeBSD/ia64 was never fully
implemented in X11. Thus, nothing gets broken that didn't need more work

Unlike TX interrupt, ST201 does not provide any mechanism to
suppress RX interrupts. ste(4) can generate more than 70k RX
interrupts under heavy RX traffics such that these excessive
interrupts make system useless to process other useful things.
Maybe this was the major reason why polling support code was
introduced to ste(4).
The STE_COUNTDOWN register provides a programmable counter that
will generate an interrupt upon its expiration. We program
STE_DMACTL register to use 3.2us clock rate to drive the counter
register. Whenever ste(4) serves RX interrupt, the driver rearm
the timer to expire after STE_IM_RX_TIMER_DEFAULT time and disables
further generation of RX interrupts. This trick seems to work well
and ste(4) generates less than 8k RX interrupts even under 64 bytes
UDP torture test. Combined with TX interrupts, the total number of
interrupts are less than 10k which looks reasonable on heavily
loaded controller.
The default RX interrupt moderation time is 150us. Users can change
the value at any time with dev.ste.%d.int_rx_mod sysctl node.
Setting it 0 effectively disables the RX interrupt moderation
feature. Now we have both TX/RX interrupt moderation code so remove
loop of interrupt handler which resulted in sub-optimal performance
as well as more register accesses.
This brings hwpmc(4) support for 2nd and 3rd generation XScale cores.

transmitted frames. So request interrupt for every 16th frames. Due
to the limitation of hardware we can't suppress the interrupt as
driver should have to check TX status register. The TX status

With this change controller would not generate TX completion

flush PCI posted write by reading the register again.
While I'm here add additional delays in loop while driver waits the
completion of the reset.
If ste(4) encounter TX underrun or excessive collisions the TX MAC
of controller is stalled so driver should wake it up again. TX
underrun requires increasing TX threshold value to minimize
further TX underruns. Previously ste(4) used to reset controller
to recover from TX underrun, excessive collision and reclaiming
error. However datasheet says only TX underrun requires resetting
entire controller. So implement ste_restart_tx() that restarts TX
MAC and do not perform full reset except TX underrun case.
Now ste(4) uses CSR_READ_2 instead of CSR_READ_1 to read
STE_TX_STATUS register. This way ste(4) will also read frame id
value and we can write the same value back to STE_TX_FRAMEID
register instead of overwriting it to 0. The datasheet was wrong
in write back of STE_TX_STATUS so add some comments why we do so.
Also always invoke ste_txeoc() after ste_txeof() in ste_poll as
without reading TX status register can stall TX MAC.
is that the JBus to EBus bridges share the interrupt controller of a
sibling JBus to PCIe bridge (at least as far as the OFW device tree
is concerned, in reality they are part of the same chip) so we have to
probe and attach the latter first. That happens to be also the case
due to the fact that the JBus to PCIe bridges appear first in the OFW
device tree but it doesn't hurt to ensure the right order.
receiving incoming traffics, try harder to gracefully stop active
DMA cycles and then stop MACs. This is the way what datasheet
recommends and seems to work reliably. Resetting controller while
active DMAs are in progress is bad thing as we can't predict how
DMAs touche allocated TX/RX buffers. This change ensures controller
stop state before attempting to release allocated TX/RX buffers.

While I'm here remove unnecessary controller resets in various

interrupt. If we want to use link state change interrupt ste(4)
should also implement auto-negotiation complete handler as well as
various PHY access handling. Now link state change is handled by
mii(4) polling so it will automatically update link state UP/DOWN
events which in turn make ste(4) usable with lagg(4).
r199559 added a private timer to drive watchdog and the timer also
used to drive MAC statistics update. Because the MAC statistics
update is called whenever statistics counter reaches near-full, it
drove watchdog timer too fast such that it caused false watchdog
timeouts under heavy TX traffic conditions.
Fix the regression by separating ste_stats_update() from driving
watchdog timer and introduce a new function ste_tick() that handles
periodic job such as driving watchdog, MAC statistics update and
link state check etc.

o Removed dead code for checking STE_RXSTAT_DMADONE bit. The bit

o Added second argument count to ste_rxeof(). It is used to limit
number of iterations done in RX handler. ATM polling is the only
consumer.
o Removed ste_rxeoc() which was added to address RX stuck issue
(cvs rev 1.66). Unlike TX descriptors, ST201 supports chaining
descriptors to form a ring for RX descriptors. If RX descriptor
chaining is not supported it's possible for controller to stop
receiving incoming frames once controller pass the end of RX
descriptor which in turn requires driver post new RX
descriptors to receive more frames. For TX descriptors which
does not support chaning, we exactly do manual chaining in
driver by concatenating new descriptors to the end of previous
TX chain.
Maybe the workaround was borrowed from other drivers that does
not support RX descriptor chaining, which is not valid for ST201
controllers. I still have no idea how this address RX stuck
issue and I can't reproduce the RX stuck issue on DFE-550TX

However it seems the hardware always dma the frame to 8 bytes

This change should give RX performance boost on amd64

o Reduce number of allowed TX buffer fragments to 6 from 7. A TX
descriptor allows 7 fragments of a frame. However the CMZ field
of descriptor has just 3bits and the controller wants to see
fragment + 1 in the field. So if we have 7 fragments the field
value would be 0 which seems to cause unexpected results under
certain conditions. This change should fix occasional TX hang
observed on vge(4).
o Simplify vge_stat_locked() and add number of available TX

o Don't set VGE_TDCTL_JUMBO flag. Datasheet is not clear whether
this bit should be set by driver or write-back status bit after

this approach is that it results in somewhat confusing devinfo -r output as
well as not being very easily portable to other bus drivers.
This commit adds generic support for "reserved" resources to the resource
list API used by many bus drivers to manage the resources of child devices.
A resource may be reserved via resource_list_reserve(). This will allocate
the resource from the bus' parent without activating it.
resource_list_alloc() recognizes an attempt to allocate a reserved resource.
When this happens it activates the resource (if requested) and then returns
the reserved resource. Similarly, when a reserved resource is released via
resource_list_release(), it is deactivated (if it is active) and the
resource is then marked reserved again, but is left allocated from the
bus' parent. To completely remove a reserved resource, a bus driver may
use resource_list_unreserve(). A bus driver may use resource_list_busy()
to determine if a reserved resource is allocated by a child device or if
it can be unreserved.
The PCI bus driver has been changed to use this framework instead of
abusing rman_set_device() to keep track of reserved vs allocated resources.

Additionally, the RX routine now does not refresh mbufs

update the hardware pointer at that time. These are
performance oriented changes.
The TX side now has a cleaner simpler watchdog algorithm
as well, in TX cleanup a read of ticks is stored, that
can then be compared in local_timer to determine if
there is a hang.

single outstanding DMA read operation. Most controllers targeted to
client with PCIe bus interface(e.g. BCM5761) may have this
limitation. All controllers for servers does not have this
limitation.
Collapsing mbuf chains to reduce number of memory reads before
transmitting was most effective way to workaround this. I got about
940Mbps from 850Mbps with mbuf collapsing on BCM5761. However it
takes a lot of CPU cycles to collapse mbuf chains so add tunable to
control the number of allowed TX buffers before collapsing. The
default value is 0 which effectively disables the forced collapsing.
For most cases 2 would yield best performance(about 930Mbps)
without much sacrificing CPU cycles.
Note the collapsing is only activated when the controller is on
PCIe bus and the frame does not need TSO operation. TSO does not
seem to suffer from the hardware limitation because the payload
size is much bigger than normal IP datagram.

Because mouse input is now streamed through the TTY, it means you can

Newbus lock is automatically held when virtual operations on the device

the newbus topology, newbus lock needs to be automatically acquired and

(DPCPU), as suggested by Peter Wemm, and implement a new per-virtual
network stack memory allocator. Modify vnet to use the allocator
instead of monolithic global container structures (vinet, ...). This
change solves many binary compatibility problems associated with
VIMAGE, and restores ELF symbols for virtualized global variables.
Each virtualized global variable exists as a "reference copy", and also
once per virtual network stack. Virtualized global variables are
tagged at compile-time, placing the in a special linker set, which is
loaded into a contiguous region of kernel memory. Virtualized global
variables in the base kernel are linked as normal, but those in modules
are copied and relocated to a reserved portion of the kernel's vnet
region with the help of a the kernel linker.
Virtualized global variables exist in per-vnet memory set up when the
network stack instance is created, and are initialized statically from
the reference copy. Run-time access occurs via an accessor macro, which
converts from the current vnet and requested symbol to a per-vnet
address. When "options VIMAGE" is not compiled into the kernel, normal
global ELF symbols will be used instead and indirection is avoided.
This change restores static initialization for network stack global
variables, restores support for non-global symbols and types, eliminates
the need for many subsystem constructors, eliminates large per-subsystem
structures that caused many binary compatibility issues both for
monitoring applications (netstat) and kernel modules, removes the
per-function INIT_VNET_*() macros throughout the stack, eliminates the
need for vnet_symmap ksym(2) munging, and eliminates duplicate
definitions of virtualized globals under VIMAGE_GLOBALS.

standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.
Authentication and encryption are not implemented.
There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).
A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.
Drivers that support mesh networks right now are: ath, ral and mwl.

modularize it so that new transports can be created.
Add a transport for SATA
Add a periph+protocol layer for ATA
Add a driver for AHCI-compliant hardware.
Add a maxio field to CAM so that drivers can advertise their max
I/O capability. Modify various drivers so that they are insulated
from the value of MAXPHYS.
The new ATA/SATA code supports AHCI-compliant hardware, and will override
the classic ATA driver if it is loaded as a module at boot time or compiled
into the kernel. The stack now support NCQ (tagged queueing) for increased
performance on modern SATA drives. It also supports port multipliers.
ATA drives are accessed via 'ada' device nodes. ATAPI drives are
accessed via 'cd' device nodes. They can all be enumerated and manipulated
via camcontrol, just like SCSI drives. SCSI commands are not translated to
their ATA equivalents; ATA native commands are used throughout the entire
stack, including camcontrol. See the camcontrol manpage for further
details. Testing this code may require that you update your fstab, and
possibly modify your BIOS to enable AHCI functionality, if available.
This code is very experimental at the moment. The userland ABI/API has
changed, so applications will need to be recompiled. It may change
further in the near future. The 'ada' device name may also change as
more infrastructure is completed in this project. The goal is to
eventually put all CAM busses and devices until newbus, allowing for
interesting topology and management options.
Few functional changes will be seen with existing SCSI/SAS/FC drivers,
though the userland ABI has still changed. In the future, transports
specific modules for SAS and FC may appear in order to better support
the topologies and capabilities of these technologies.
The modularization of CAM and the addition of the ATA/SATA modules is
meant to break CAM out of the mold of being specific to SCSI, letting it
grow to be a framework for arbitrary transports and protocols. It also
allows drivers to be written to support discrete hardware without
jeopardizing the stability of non-related hardware. While only an AHCI
driver is provided now, a Silicon Image driver is also in the works.
Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware
is possible and encouraged. Help with new transports is also encouraged.

inbound data waiting on a filedescriptor, such as a pipe or a socket,
for instance by using select(2), poll(2), kqueue(2), ioctl(FIONREAD)
etc.
But we have no way of finding out if written data have yet to be
disposed of, for instance, transmitted (and ack'ed!) to some remote
host, or read by the applicantion at the far end of the pipe.
The closest we get, is calling shutdown(2) on a TCP socket in
non-blocking mode, but this has the undesirable sideeffect of
preventing future communication.
Add a complement to FIONREAD, called FIONWRITE, which returns the
number of bytes not yet properly disposed of. Implement it for
all sockets.
Background:
A HTTP server will want to time out connections, if no new request
arrives within a certain period after the last transmitted response
has actually been sent (and ack'ed).
For a busy HTTP server, this timeout can be subsecond duration.
In order to signal to a load-balancer that the connection is truly
dead, TCP_RST will be the preferred method, as this avoids the need
for a RTT delay for FIN handshaking, with a client which, surprisingly
often, no longer at the remote IP number.
If a slow, distant client is being served a response which is big
enough to fill the window, but small enough to fit in the socket
buffer, the write(2) call will return immediately.

rlimit RLIMIT_SWAP that limits the amount of swap that may be reserved
for the uid.
The accounting information (charge) is associated with either map entry,
or vm object backing the entry, assuming the object is the first one
in the shadow chain and entry does not require COW. Charge is moved
from entry to object on allocation of the object, e.g. during the mmap,
assuming the object is allocated, or on the first page fault on the
entry. It moves back to the entry on forks due to COW setup.
The per-entry granularity of accounting makes the charge process fair
for processes that change uid during lifetime, and decrements charge
for proper uid when region is unmapped.
The interface of vm_pager_allocate(9) is extended by adding struct ucred *,
that is used to charge appropriate uid when allocation if performed by
kernel, e.g. md(4).
Several syscalls, among them is fork(2), may now return ENOMEM when

multicast filter programming until controller becomes idle state.
To detect when the controller is idle fxp(4) relied on Tx
completion interrupt with NOP command and fxp_start_body and
fxp_intr_body had to see whether pending multicast filter

sometimes it did not work as expected.
Since the controller should be in idle state before any multicast

Summary of changes includes:
1 Volume Per-Channel (vpc). Provides private / standalone volume control
unique per-stream pcm channel without touching master volume / pcm.
Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for
backwards compatibility, SOUND_MIXER_PCM through the opened dsp device
instead of /dev/mixer. Special "bypass" mode is enabled through
/dev/mixer which will automatically detect if the adjustment is made
through /dev/mixer and forward its request to this private volume
controller. Changes to this volume object will not interfere with
other channels.
Requirements:
- SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which
require specific application modifications (preferred).
- No modifications required for using bypass mode, so applications
like mplayer or xmms should work out of the box.
Kernel hints:
- hint.pcm.%d.vpc (0 = disable vpc).
Kernel sysctls:
- hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer
bypass mode.
- hw.snd.vpc_autoreset (default: 1). By default, closing/opening
/dev/dsp will reset the volume back to 0 db gain/attenuation.
Setting this to 0 will preserve its settings across device
closing/opening.
- hw.snd.vpc_reset (default: 0). Panic/reset button to reset all
volume settings back to 0 db.
- hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value.

script written in awk (the clumsiest joke I've ever written)
- 100% 32bit fixed-point, 64bit accumulator.
- Possibly among the fastest (if not fastest) of its kind.
- Resampling quality is tunable, either runtime or during kernel
compilation (FEEDER_RATE_PRESETS).
- Quality can be further customized during kernel compilation by
defining FEEDER_RATE_PRESETS in /etc/make.conf.
Kernel sysctls:
- hw.snd.feeder_rate_quality.
0 - Zero-order Hold (ZOH). Fastest, bad quality.
1 - Linear Interpolation (LINEAR). Slightly slower than ZOH,
better quality but still does not eliminate aliasing.
2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC
quality always start from 2 and above.
Rough quality comparisons:
- http://people.freebsd.org/~ariff/z_comparison/
3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be
directly fed into the hardware.
4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can
be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.
5 Transparent/Adaptive Virtual Channel. Now you don't have to disable
vchans in order to make digital format pass through. It also makes
vchans more dynamic by choosing a better format/rate among all the
concurrent streams, which means that dev.pcm.X.play.vchanformat/rate
becomes sort of optional.
6 Exclusive Stream, with special open() mode O_EXCL. This will "mute"
other concurrent vchan streams and only allow a single channel with
O_EXCL set to keep producing sound.

- Each socket upcall is now invoked with the appropriate socket buffer
locked. It is not permissible to call soisconnected() with this lock
held; however, so socket upcalls now return an integer value. The two
possible values are SU_OK and SU_ISCONNECTED. If an upcall returns
SU_ISCONNECTED, then the soisconnected() will be invoked on the
socket after the socket buffer lock is dropped.
- A new API is provided for setting and clearing socket upcalls. The
API consists of soupcall_set() and soupcall_clear().
- To simplify locking, each socket buffer now has a separate upcall.
- When a socket upcall returns SU_ISCONNECTED, the upcall is cleared from
the receive socket buffer automatically. Note that a SO_SND upcall
should never return SU_ISCONNECTED.
- All this means that accept filters should now return SU_ISCONNECTED
instead of calling soisconnected() directly. They also no longer need
to explicitly clear the upcall on the new socket.
- The HTTP accept filter still uses soupcall_set() to manage its internal
state machine, but other accept filters no longer have any explicit
knowlege of socket upcall internals aside from their return value.
- The various RPC client upcalls currently drop the socket buffer lock
while invoking soreceive() as a temporary band-aid. The plan for
the future is to add a new flag to allow soreceive() to be called with
the socket buffer locked.
- The AIO callback for socket I/O is now also invoked with the socket
buffer locked. Previously sowakeup() would drop the socket buffer
lock only to call aio_swake() which immediately re-acquired the socket
buffer lock for the duration of the function call.

to be there, to keep drivers like syscons happy. So I'm creating a
tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex()
should eventually be removed.
The advantage of this approach, is that we can just remove a function,
without breaking the regular API in the future.
Calculate the exact number of vectors we'll use before calling
pci_alloc_msix. Don't grab nine all the time.
Call cxgb_setup_interrupts once per T3, not once per port. Ditto
for cxgb_teardown_interrupts.
Don't leak resources when interrupt setup fails in the middle.

to dequeue a packet.
The tx path was trying to ensure that enough Xenbus TX ring slots existed but
it didn't check to see whether the mbuf TX ring slots were also available.
They get freed in xn_txeof() which occurs after transmission, rather than earlier
on in the process. (The same happens under Linux too.)
Due to whatever reason (CPU use, scheduling, memory constraints, whatever) the
mbuf TX ring may not have enough slots free and would allocate slot 0. This is
used as the freelist head pointer to represent "free" mbuf TX ring slots; setting
this to an actual mbuf value rather than an id crashes the code.
This commit introduces some basic code to track the TX mbuf ring use and then
(hopefully!) ensures that enough slots are free in said TX mbuf ring before it
enters the actual work loop.
A few notes:
* Similar logic needs to be introduced to check there are enough actual slots
available in the xenbuf TX ring. There's some logic which is invoked earlier
but it doesn't hard-check against the number of available ring slots.
Its trivial to do; I'll do it in a subsequent commit.
* As I've now commented in the source, it is likely possible to deadlock the
driver under certain conditions where the rings aren't receiving any changes
(which I should enumerate) and thus Xen doesn't send any further software
interrupts. I need to make sure that the timer(s) are running right and
the queues are periodically kicked.

Slot 0 must always remain "free" and be a pointer to the first free entry in the
mbuf descriptor list. It is thus an error to have code allocate or push slot 0
back into the list.
get a quick snapshot of the kernel's symbol table including the symbols
from any loaded modules (the symbols are all merged into one symbol

memory in the process memory space to store the snapshot at the time
/dev/ksyms is opened. It also checks to see if the process has already
a snapshot open and won't allow it to open /dev/ksyms it again until it
closes first. This prevents kernel and process memory from being
exhausted. Note that /dev/ksyms is used by the lockstat(1) command.

o Header file cleanup.
o bus_dma(9) conversion.
- Removed all consumers of vtophys(9) and converted to use
bus_dma(9).
- 64bit DMA support was disabled because DP83821 is not capable
of handling the DMA request. 64bit DMA request on DP83820
requires different descriptor structures and it's hard to
dynamically change descriptor format at run time so I disabled
it. Note, this is the same behavior as previous one but
previously nge(4) didn't explicitly disable 64bit mode on
DP83820.
- Added Tx/Rx descriptor ring alignment requirements(8 bytes
alignment).
- Limit maximum number of Tx DMA segments to 16. In fact,
controller does not seem to have limitations on number of Tx
DMA segments but 16 should be enough for most cases and
m_collapse(9) will handle highly fragmented frames without
consuming a lot of CPU cycles.
- Added Rx buffer alignment requirements(8 bytes alignment). This
means driver should fixup received frames to align on 16bits
boundary on strict-alignment architectures.
- Nuked driver private data structure in descriptor ring.
- Added endianness support code in Tx/Rx descriptor access.
o Prefer faster memory mapped register access to I/O mapped access.
Added fall-back mechanism to use alternative register access.
The hardware supports both memory and I/O mapped access.
o Added suspend/resume methods but it wasn't tested as controller I
have does not support PCI PME.
o Removed swap argument in nge_read_eeprom() since endianness
should be handled after reading EEPROM.
o Implemented experimental 802.3x full-duplex flow-control. ATM
it was commented out but will be activated after we have generic
flow-control framework in mii(4) layer.
o Rearranged promiscuous mode settings and simplified logic.
o Always disable Rx filter prior to changing Rx filter functions as
indicated in DP83820/DP83821 datasheet.
o Added an explicit DELAY in timeout loop of nge_reset().
o Added a sysctl variable dev.nge.%d.int_holdoff to control
interrupt moderation. Valid ranges are 1 to 255(default 1) in
units of 100us. The actual delivery of interrupt would be delayed
based on the sysctl value. The interface has to be brought down
and up again before a change takes effect. With proper tuning
value, users do not need to resort to polling(4) anymore.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as nge(4) can offload Tx/Rx
checksum calculation on VLAN tagged frames as well as VLAN tag
insertion/stripping. Also add IFCAP_VLAN_MTU capability as nge(4)
can handle VLAN tagged oversized frames.
o Fixed media header length for VLAN.
o Rearranged nge_detach routine such that it's now used for general
clean-up routine.
o Enabled MWI.
o Accessing EEPROM takes very long time so read 6 bytes ethernet
address with one call instead of 3 separate accesses.
o Don't set if_mtu in device attach, it's already set in
ether_ifattach().
o Don't do any special things for TBI interface. Remove TBI
specific media handling in the driver and have gentbi(4) handle
it. Add glue code to read/write TBI PHY registers in miibus
method. This change removes a lot of PHY handling code in driver
and now its functionality is handled by mii(4).
o Alignment fixup code is now applied only for strict-alignment
architectures. Previously the code was applied for all
architectures except i386. With this change amd64 will get
instant Rx performance boost.
o When driver fails to allocate a new mbuf, update if_qdrops so
users can see what was wrong in Rx path.
o Added a workaround for a hardware bug which resulted in short
VLAN tagged frames(e.g. ARP) was rejected as if runt frame was
received. With this workaround nge(4) now accepts the short VLAN
tagged frame and nge(4) can take full advantage of hardware VLAN
tag stripping. I have no idea how this bug wasn't known so far,
without the workaround nge(4) may never work on VLAN
environments.
o Fixed Rx checksum offload logic such that it now honors active
interface capability configured with ifconfig(8).
o In nge_start()/nge_txencap(), always leave at least one free
descriptor as indicated in datasheet. Without this the hardware
would be confused with ring descriptor structure(e.g. no clue
for the end of descriptor ring).
o Removed dead-code that checks interrupts on PHY hardware. The
code was designed to detect link state changes but it was
disabled as driving nge_tick clock would break auto-negotiation
timer. This code is no longer needed as nge(4) now uses mii(4)
and link state change handling is done with mii callback.
o Rearranged ethernet address programming logic such that it works
on strict-alignment architectures.
o Added IFCAP_VLAN_HWTAGGING/IFCAP_VLAN_HWCSUM handler in
nge_ioctl() such that the functionality is configurable with
ifconfig(8). DP83820/DP83821 can do checksum offload for VLAN
tagged frames so enable Tx/Rx checksum offload for VLAN
interfaces.
o Simplified IFCAP_POLLING selection logic in nge_ioctl().
o Fixed module unload panic when bpf listeners are active.
o Tx/Rx descriptor ring address uses 64bit DMA address for
readability. High address part of DMA would be 0 as nge(4)
disabled 64bit DMA transfers so it's ok for DP83821.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
take care of this.
o Removed extra driver private structures in descriptor ring. These
extra elements are not part of descriptor structure. Embedding
private driver structure into descriptor ring is not good idea
as its size may be different on 32bit/64bit architectures.
o Added miibus_linkchg method handler to catch link state changes.
o Removed unneeded nge_ifmedia in softc. All TBI access is handled
in gentbi(4). There is no difference between TBI and non-TBI case
now.
o Removed "gigabit link up" message handling in nge_tick. Link
state change notification is already performed by mii(4) and
checking link state by accessing PHY registers in periodic timer
handler of driver is wrong. All link state and speed/duplex
monitoring should be handled in PHY driver.
o Use our own timer for watchdog instead of if_watchdog/if_timer
interface.
o Added hardware MAC statistics counter, users canget current MAC
statistics from dev.nge.%d.stats sysctl node(%d is unit number of
a device).
o Removed unused macros, NGE_LASTDESC, NGE_MODE, NGE_OWNDESC,
NGE_RXBYTES.
o Increased number of Tx/Rx descriptors from 128 to 256. From my
experience on gigabit ethernet controllers, number of descriptors
should be 256 or higher to get an optimal performance on gigabit
link.
o Increased jumbo frame length to 9022 bytes to cope with other
gigabit ethernet drivers. Experimentation shows no problems with
9022 bytes.
o Removed unused member variables in softc.

the DMA-based I/O read operations for which D-cache are already

the bcopy() followed by the D-cache flush can be integrated in a
single operation, which could be implemented using on-chips DMA

previously always pointing to the default vnet context, to a
dynamically changing thread-local one. The currvnet context
should be set on entry to networking code via CURVNET_SET() macros,
and reverted to previous state via CURVNET_RESTORE(). Recursions
on curvnet are permitted, though strongly discuouraged.
This change should have no functional impact on nooptions VIMAGE
kernel builds, where CURVNET_* macros expand to whitespace.
The curthread->td_vnet (aka curvnet) variable's purpose is to be an
indicator of the vnet context in which the current network-related
operation takes place, in case we cannot deduce the current vnet
context from any other source, such as by looking at mbuf's
m->m_pkthdr.rcvif->if_vnet, sockets's so->so_vnet etc. Moreover, so
far curvnet has turned out to be an invaluable consistency checking
aid: it helps to catch cases when sockets, ifnets or any other
vnet-aware structures may have leaked from one vnet to another.
The exact placement of the CURVNET_SET() / CURVNET_RESTORE() macros
was a result of an empirical iterative process, whith an aim to
reduce recursions on CURVNET_SET() to a minimum, while still reducing
the scope of CURVNET_SET() to networking only operations - the
alternative would be calling CURVNET_SET() on each system call entry.
In general, curvnet has to be set in three typicall cases: when
processing socket-related requests from userspace or from within the
kernel; when processing inbound traffic flowing from device drivers
to upper layers of the networking stack, and when executing
timer-driven networking functions.
This change also introduces a DDB subcommand to show the list of all

When a driver callback completes the hardware state is now guaranteed to have

This nukes around 1300 lines of code from the wireless device drivers making
them more readable and less race prone.
The net80211 layer has been updated as follows
- all state/channel changes are serialised on the taskqueue.
- ieee80211_new_state() always queues and can now be called from any context
- scanning runs from a single taskq function and executes to completion. driver
callbacks are synchronous so the channel, phy mode and rx filters are

o Header file cleanup.
o bus_dma(9) conversion.
- Removed all consumers of vtophys(9) and converted to use
bus_dma(9).
- Typhoon2 functional specification says the controller supports
64bit DMA addressing. However all Typhoon controllers are known
to lack of DAC support so 64bit DMA support was disabled.
- The hardware can't handle more 16 fragmented Tx DMA segments so
teach txp(4) to collapse these segments to be less than 16.
- Added Rx buffer alignment requirements(4 bytes alignment) and
implemented fixup code to align receive frame. Previously
txp(4) always copied Rx frame to align it on 2 byte boundary
but its copy overhead is much higher than unaligned access on
i386/amd64. Alignment fixup code is now applied only for
strict-alignment architectures. With this change i386 and
amd64 will get instant Rx performance boost. Typhoon2 datasheet
mentions a command that pads arbitrary bytes in Rx buffer but
that command does not work.
- Nuked pointer trick in descriptor ring. This does not work on
sparc64 and replaced it with bcopy. Alternatively txp(4) can
embed a 32 bits index value into the descriptor and compute
real buffer address but it may make code complicated.
- Added endianness support code in various Tx/Rx/command/response
descriptor access. With this change txp(4) should work on all
architectures.
o Added comments for known firmware bugs(Tx checksum offloading,
TSO, VLAN stripping and Rx buffer padding control).
o Prefer faster memory space register access to I/O space access.
Added fall-back mechanism to use alternative I/O space access.
The hardware supports both memory and I/O mapped access. Users
can still force to use old I/O space access by setting
hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
o Added experimental suspend/resume methods.
o Nuke error prone Rx buffer handling code and implemented local
buffer management with TAILQ. Be definition the controller can't
pass the last received frame to host if no Rx free buffers are
available to use as head and tail pointer of Rx descriptor ring
can't have the same value. In that case the Rx buffer pointer in
Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
can't fill Rx buffers as the first buffer is still valid. Instead
of relying on the value of Rx buffer ring, introduce local buffer
management code to handle empty buffer situation. This should fix
a long standing bug which completely hangs the controller under
high network load. I could easily trigger the issue by sending 64
bytes UDP frames with netperf. I have no idea how this bugs was
not fixed for a long time.
o Converted ithread interrupt handler to filter based one.
o Rearranged txp_detach routine such that it's now used for general
clean-up routine.
o Show sleep image version on device attach time. This will help
to know what action should be taken depending on sleep image
version. The version information in datasheet was wrong for newer
NV images so I followed Linux which seems to correctly extract
version numbers from response descriptors.
o Firmware image is no longer downloaded in device attach time. Now
it is reloaded whenever if_init is invoked. This is to ensure
correct operation of hardware when something goes wrong.
Previously the controller always run without regard to running
state of firmware. This change will add additional controller
initialization time but it give more robust operation as txp(4)
always start off from a known state. The controller is put into
sleep state until administrator explicitly up the interface.
o As firmware is loaded in if_init handler, it's now possible to
implement real watchdog timeout handler. When watchdog timer is
expired, full-reset the controller and initialize the hardware
again as most other drivers do. While I'm here use our own timer
for watchdog instead of using if_watchdog/if_timer interface.
o Instead of masking specific interrupts with TXP_IMR register,
program TXP_IER register with the interrupts to be raised and
use TXP_IMR to toggle interrupt generation.
o Implemented txp_wait() to wait a specific state of a controller.
o Separate boot related code from txp_download_fw() and name it
txp_boot() to handle boot process.
o Added bus_barrier(9) to host to ARM communication.
o Added endianness to all typhoon command processing. The ARM93C
always expects little-endian format of command/data.
o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
__NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
Previously __STRICT_ALIGNMENT was unconditionally defined for
all architectures.
o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
controlled by ifconfig(8). Note, disabling VLAN hardware tagging
has no effect due to the bug of firmware.
o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
txp_tick(). The command is not atomic. Instead, just read the
statistics and reflect saved statistics to the statistics.
dev.txp.%d.stats sysctl node provides detailed MAC statistics.
This also reduces a lot of waste of CPU cycles as processing a
command ring takes a very long time on ARM93C. Note, Rx
multicast and broadcast statistics does not seem to right. It
might be another bug of firmware.
o Implemented link state change handling in txp_tick(). Now sending
packets is allowed only after establishing a valid link. Also
invoke link state change notification whenever its state is
changed so pseudo drivers like lagg(4) that relies on link state
can work with failover or link aggregation without hacks.
if_baudrate is updated to resolved speed so SNMP agents can get
correct bandwidth parameters.
o Overhauled Tx routine such that it now honors number of allowable
DMA segments and checks for 4 free descriptors before trying to
send a frame. A frame may require 4 descriptors(1 frame
descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
one free descriptor to prevent descriptor wrap-around) at least
so it's necessary to check available free descriptors prior to
setting up DMA operation.
o Added a sysctl variable dev.txp.%d.process_limit to control
how many received frames should be served in Rx handler. Valid
ranges are 16 to 128(default 64) in unit of frames.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
calculation as well as VLAN tag insertion/stripping.
o Fixed media header length for VLAN.
o Don't set if_mtu in device attach, it's already set in
ether_ifattach().
o Enabled MWI.
o Fixed module unload panic when bpf listeners are active.
o Rearranged ethernet address programming logic such that it works
on strict-alignment architectures.
o Removed unused member variables in softc.

filesystem supports additional operations using shared vnode locks.
Currently this is used to enable shared locks for open() and close() of
read-only file descriptors.
- When an ISOPEN namei() request is performed with LOCKSHARED, use a
shared vnode lock for the leaf vnode only if the mount point has the
extended shared flag set.
- Set LOCKSHARED in vn_open_cred() for requests that specify O_RDONLY but
not O_CREAT.
- Use a shared vnode lock around VOP_CLOSE() if the file was opened with
O_RDONLY and the mountpoint has the extended shared flag set.
- Adjust md(4) to upgrade the vnode lock on the vnode it gets back from
vn_open() since it now may only have a shared vnode lock.
- Don't enable shared vnode locks on FIFO vnodes in ZFS and UFS since
FIFO's require exclusive vnode locks for their open() and close()
routines. (My recent MPSAFE patches for UDF and cd9660 already included
this change.)

Because the kernel messages didn't share the same terminal emulator as
ttyv0, this caused a lot of strange things, like kernel messages being

A while back, Warner changed the PCI bus code to reserve resources when
enumerating devices and simply give devices the previously allocated
resources when they call bus_alloc_resource(). This ensures that address
ranges being decoded by a BAR are always allocated in the nexus0 device
(or whatever device the PCI bus gets its address space from) even if a
device driver is not attached to the device. This patch extends this
behavior further:
- To let the PCI bus distinguish between a resource being allocated by
a device driver vs. merely being allocated by the bus, use
rman_set_device() to assign the device to the bus when it is owned
by the bus and to the child device when it is allocated by the child
device's driver. We can now prevent a device driver from allocating
the same device twice. Doing so could result in odd things like
allocating duplicate virtual memory to map the resource on some
archs and leaking the original mapping.
- When a PCI device driver releases a resource, don't pass the request
all the way up the tree and release it in the nexus (or similar device)
since the BAR is still active and decoding. Otherwise, another device
could later allocate the same range even though it is still in use.
Instead, deactivate the resource and assign it back to the PCI bus
using rman_set_device().
- pci_delete_resource() will actually completely free a BAR including
attemping to disable it.
- Disable BAR decoding via the command register when sizing a BAR in
pci_alloc_map() which is used to allocate resources for a BAR when
the BIOS/firmware did not assign a usable resource range during boot.
This mirrors an earlier fix to pci_add_map() which is used when to
size BARs during boot.
- Move the activation of I/O decoding in the PCI command register into
pci_activate_resource() instead of doing it in pci_alloc_resource().
Previously we could actually enable decoding before a BAR was
initialized via pci_alloc_map().

This addresses interrupt storms that were noticed after enabling MSI
in drm. I think this is due to a loose interpretation of the PCI 2.3
spec, which states that a function using MSI is prohibitted from using
INTx. It appears that some vendors interpretted that to mean that they
should handle it in hardware, while others felt it was the drivers
responsibility.
This fix will also likely resolve interrupt storm related issues with

- specification claims that 1 second is just a maximum controller reset time;
implement controller reset properly to save almost 1 second of boot, and
about half second of resume time;
- enable channel interrupts only after channel status reset to fix duplicate
device creation on resume due to unwanted device connection event;
- as described in specification, wait for disk ready status after channel
power-up; it is not so important when disk already touched by BIOS, but
solves device not ready problems on resume and probably some other cases.
- uncomment channel stop/start on soft-reset as it is declared mandatory by
specification; it was commented due to some random drive detection problems
on VIA and JMicron controllers, but I hope it is fixed by previous point.

The TTY buffers used the standard <sys/queue.h> lists. Unfortunately
they have a big shortcoming. If you want to have a double linked list,
but no tail pointer, it's still not possible to obtain the previous

I switched to custom linked list macros. The macros will also keep track
of the amount of items in the list. Because it doesn't use a sentinel,
we can just initialize the queues with zero.
In its simplest form (the output queue), we will only keep two
references to blocks in the queue, namely the head of the list and the
last block in use. All free blocks are stored behind the last block in

Introduce much more locking around fc->mtx. Tested this for lock reversals

a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before
the code responsible for asserting BUS RESET was complete. This locking
fixes that issue.

o change api for ath_hal_init_channels: no more reglass id's, no more outdoor
indication (was a noop), anM contents
o add ath_hal_getchannels to have the hal construct a channel list without
altering runtime state; this is used to retrieve the calibration list for
the device in ath_getradiocaps
o add ath_hal_set_channels to take a channel list and regulatory data from
above and construct internal state to match (maps frequencies for 900MHz
cards, setup for CTL lookups, etc)
o compact the private channel table: we keep one private channel
per frequency instead of one per HAL_CHANNEL; this gives a big
space savings and potentially improves ani and calibration by
sharing state (to be seen; didn't see anything in testing); a new config
option AH_MAXCHAN controls the table size (default to 96 which
was chosen to be ~3x the largest expected size)
o shrink ani state and change to mirror private channel table (one entry per
frequency indexed by ic_devdata)
o move ani state flags to private channel state
o remove country codes; use net80211 definitions instead
o remove GSM regulatory support; it's no longer needed now that we
pass in channel lists from above
o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A
o simplify initial channel list construction based on the EEPROM contents;
we preserve country code support for now but may want to just fallback
to a WWR sku and dispatch the discovered country code up to user space
so the channel list can be constructed using the master regdomain tables
o defer to net80211 for max antenna gain
o eliminate sorting of internal channel table; now that we use ic_devdata

o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one
of the driver-private flag bits of the net80211 channel
o move 900MHz frequency mapping into the hal; the mapped frequency is stored
in the private channel and used throughout the hal (no more mapping in the
driver and/or net80211)
o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the
calculation and available in the net80211 channel
o change noise floor calibration logic to work with compacted private channel
table setup; this may require revisiting as we no longer can distinguish
channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used
only to calculate status data we can live with it for now

instead of all channels in the private channel table

o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory
problems
o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now
o change ath_hal_getwirelessmodes to really return wireless modes supported
by the hardware (was previously applying regulatory constraints)
o return channel interference status with IEEE80211_CHANSTATE_CWINT (should
change to a callback so hal api's can take const pointers)

Inside the kernel, the minor() function was responsible for obtaining
the device minor number of a character device. Because we made device
numbers dynamically allocated and independent of the unit number passed
to make_dev() a long time ago, it was actually a misnomer. If you really
want to obtain the device number, you should use dev2udev().
We already converted all the drivers to use dev2unit() to obtain the
device unit number, which is still used by a lot of drivers. I've
noticed not a single driver passes NULL to dev2unit(). Even if they
would, its behaviour would make little sense. This is why I've removed
the NULL check.
Ths commit removes minor(), minor2unit() and unit2minor() from the
kernel. Because there was a naming collision with uminor(), we can
rename umajor() and uminor() back to major() and minor(). This means
that the makedev(3) manual page also applies to kernel space code now.
I suspect umajor() and uminor() isn't used that often in external code,
but to make it easier for other parties to port their code, I've

- To avoid having a bunch of locks that end up always getting acquired as
a group, give each ppc(4) device a mutex which it shares with all the
child devices including ppbus(4), lpt(4), plip(4), etc. This mutex
is then used for all the locking.
- Rework the interrupt handling stuff yet again. Now ppbus drivers setup
their interrupt handler during attach and tear it down during detach
like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.

- Other lpt(4) changes:
- Use device_printf().
- Use a dedicated callout for the lptout timer.
- Allocate the I/O buffers at attach and detach rather than during
open and close as this simplifies the locking at the cost of

- Use an sx lock to serialize open and close.
- Remove unused HADBUS flag.
- Add a detach routine.
- Use a malloc'd buffer for each read and write to avoid races with

- Other pps(4) changes:
- Use a callout rather than a callout handle with timeout().
- Conform to the new ppbus requirements (regular mutex, non-filter
interrupt handler). pps(4) is probably going to have to become a

requirements for low latency as a result.

Add a small array to convert syscons-style color codes to ANSI

It turns out I forgot to implement two escape sequences that allows the

they were implemented by syscons itself, but vidcontrol just generates

o Added a new tunable hw.mskc.jumbo_disable to disable jumbo

failure it just disables jumbo frame support and continues to

Using local allocator had several drawbacks such as requirement of

Also small number of buffer used in local allocator showed poor

The cursor is only inside the scrolling region when we are in origin

completely valid to place the cursor outside the scrolling region.
Some time ago I started working on a library called libteken, which is
terminal emulator. It does not buffer any screen contents, but only
keeps terminal state, such as cursor position, attributes, etc. It
should implement all escape sequences that are implemented by the
cons25 terminal emulator, but also a fair amount of sequences that are
present in VT100 and xterm.
A lot of random notes, which could be of interest to users/developers:
- Even though I'm leaving the terminal type set to `cons25', users can
do experiments with placing `xterm-color' in /etc/ttys. Because we
only implement a subset of features of xterm, this may cause
artifacts. We should consider extending libteken, because in my
opinion xterm is the way to go. Some missing features:
- Keypad application mode (DECKPAM)
- Character sets (SCS)
- libteken is filled with a fair amount of assertions, but unfortunately
we cannot go into the debugger anymore if we fail them. I've done
development of this library almost entirely in userspace. In
sys/dev/syscons/teken there are two applications that can be helpful
when debugging the code:
- teken_demo: a terminal emulator that can be started from a regular
xterm that emulates a terminal using libteken. This application can
be very useful to debug any rendering issues.
- teken_stress: a stress testing application that emulates random
terminal output. libteken has literally survived multiple terabytes
of random input.
- libteken also includes support for UTF-8, but unfortunately our input
layer and font renderer don't support this. If users want to
experiment with UTF-8 support, they can enable `TEKEN_UTF8' in
teken.h. If you recompile your kernel or the teken_demo application,
you can hold some nice experiments.
- I've left PC98 the way it is right now. The PC98 platform has a custom
syscons renderer, which supports some form of localised input. Maybe
we should port PC98 to libteken by the time syscons supports UTF-8?
- I've removed the `dumb' terminal emulator. It has been broken for
years. It hasn't survived the `struct proc' -> `struct thread'
conversion.
- To prevent confusion among people that want to hack on libteken:
unlike syscons, the state machines that parse the escape sequences are
machine generated. This means that if you want to add new escape
sequences, you have to add an entry to the `sequences' file. This will
cause new entries to be added to `teken_state.h'.
- Any rendering artifacts that didn't occur prior to this commit are by
accident. They should be reported to me, so I can fix them.

controllers. ICH based controllers are treated as 82559. 82557,
earlier revision of 82558 and 82559ER have no WOL capability.
o WOL support requires help of a firmware so add check whether
hardware is capable of handling magic frames by reading EEPROM.
o Enable accepting WOL frames only when hardware is about to
suspend or shutdown. Previously fxp(4) used to allow receipt of
magic frame under normal operation mode which could cause
hardware hang if magic frame is received by hardware. Datasheet
clearly states driver should not allow WOL frames under normal
operation mode.
o Disable WOL frame reception in device attach so have fxp(4)
immunize against system hang which can be triggered by magic
packets when the hardware is not in fully initialized state.
o Don't reset all hardware configuration data in fxp_stop()
otherwise important configuration data is lost and this would
reset WOL configuration to default state which in turn cause
hardware hang on receipt of magic frames. To fix the issue,
preserve hardware configuration data by issuing a selective
reset.
o Explicitly disable interrupts after issuing selective reset as
reset may unmask interrupts.

contention with management hardware. However, in order to

- u3g_speeds contains speeds in baud, not bytes per second, so divide

o Configure controller to use dynamic TBD as TSO requires that
operation mode.
o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
operation.
o Increase a DMA segment size to 4096 to hold a full IP segment
with link layer header.
o Unlike other TSO capable controllers, 82550/82551 does not
modify the first IP packet in TSO operation so driver should
create an IP packet with proper header. Subsequent IP packets
are generated from the header information in the first IP packet
header. Likewise pseudo checksum also should be computed by
driver for the first packet.
o TSO requires one more TBD to hold total TCP payload. To make
code simple for TSO/non-TSO case, increase the index of the
first available TBD array.
o Remove KASSERT that checks the size of a DMA segment should be
less than or equal to MCLBYTES as it's no longer valid in TSO.
o Tx threshold and number of TBDs field is used to store MSS in
TSO. So don't set the Tx threshold in TSO case.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.
Rx buffer and loads DMA map. Also add a function
fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
this change fxp_add_rfabuf just handles appending a new RFA to
existing chain.
o Initialize mbuf length in fxp_new_rfabuf.
o Don't reset rnr and have fxp(4) handle received frames even if
it couldn't allocate new Rx buffer. This will make fxp(4) reload
updated RFA under rnr case. The rnr would still be reset to 0 if
polling is active and fxp(4) processed number of allowed Rx
events.
o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.
Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.

- Don't count number of mbuf chains. Default 32 DMA segments for a
frame is enough for most cases. If bus_dmamap_mbuf_sg fails use

expensive m_defrag(9).
- Move bpf handling to fxp_start_body() which is supposed to be
more appropriate place.
- Always arm watchdog timer whenever a new Tx request is made.
Previously fxp(4) used to arm watchdog timer only when
FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not
rely on Tx interrupt to reclaim transmitted mbufs it's better to
arm watchdog timer to detect potential lockups.
- Add more aggresive Tx buffer reclaiming in fxp_start_body to make
room for new Tx requests. Since fxp(4) does not request Tx
completion interrupt for every frames it's necessary to clean
TXCBs in advance to saturate link.
- Make fxp(4) try to start more packets transmitting regardless of

Instead of initializing the affected global variables at instatiation,
assign initial values to them in initializer functions. As a rule,
initialization at instatiation for such variables should never be
introduced again from now on. Furthermore, enclose all instantiations
of such global variables in #ifdef VIMAGE_GLOBALS blocks.
Essentialy, this change should have zero functional impact. In the next
phase of merging network stack virtualization infrastructure from
p4/vimage branch, the new initialization methology will allow us to
switch between using global variables and their counterparts residing in
virtualization containers with minimum code churn, and in the long run
allow us to intialize multiple instances of such container structures.

L2E(AR8113/AR8114). Unlike its predecessor Attansic L1,
AR8121/AR8113/AR8114 uses completely different Rx logic such that
it requires separate driver. Datasheet for AR81xx is not available
to open source driver writers but it shares large part of Tx and
PHY logic of L1. I still don't understand some part of register
meaning and some MAC statistics counters but the driver seems to
have no critical issues for performance and stability.
The AR81xx requires copy operation to pass received frames to upper
stack such that ale(4) consumes a lot of CPU cycles than that of
other controller. A couple of silicon bugs also adds more CPU
cycles to address the known hardware bug. However, if you have fast
CPU you can still saturate the link.
Currently ale(4) supports the following hardware features.

- TCP Segmentation offload.
- Hardware VLAN tag insertion/stripping with checksum offload.

On RELENG_6 (and probably RELENG_7) we see our syscons windows and
pseudo-terminals have the following buffer sizes:
| LINE RAW CAN OUT IHIWT ILOWT OHWT LWT COL STATE SESS PGID DISC
| ttyv0 0 0 0 7680 6720 2052 256 7 OCcl 1146 1146 term
| ttyp0 0 0 0 7680 6720 1296 256 0 OCc 82033 82033 term
These buffer sizes make no sense, because we often have much more output
than input, but I guess having higher input buffer sizes improves
guarantees of the system.
On MPSAFE TTY I just sent both the input and output buffer sizes to 7
KB, which is pretty big on a standard FreeBSD install with 8 syscons
windows and some PTY's. Reduce the baud rate to 9600 baud, which means
we now have the following buffer sizes:
| LINE INQ CAN LIN LOW OUTQ USE LOW COL SESS PGID STATE
| ttyv0 1920 0 0 192 1984 0 199 7 2401 2401 Oil
| pts/0 1920 0 0 192 1984 0 199 5631 1305 2526 Oi
This is a lot smaller, but for pseudo-devices this should be good
enough. You need to do a lot of punching to fill up a 7.5 KB input
buffer. If it turns out things don't work out this way, we'll just
switch to 19200 baud.

Instead, the caller merely needs to ensure a reference is held on the

gain a new reference (via vhold()) on p_textvp to fully close races with

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:
1) A brief feature list:
- A new and mutex enabled USB API.
- Many USB drivers are now running Giant free.
- Linux USB kernel compatibility layer.
- New UGEN backend and libusb library, finally solves the "driver
unloading" problem. The new BSD licensed libusb20 library is fully
compatible with libusb-0.1.12 from sourceforge.
- New "usbconfig" utility, for easy configuration of USB.
- Full support for Split transactions, which means you can use your
full speed USB audio device on a high speed USB HUB.
- Full support for HS ISOC transactions, which makes writing drivers
for various HS webcams possible, for example.
- Full support for USB on embedded platforms, mostly cache flushing
and buffer invalidating stuff.
- Safer parsing of USB descriptors.
- Autodetect of annoying USB install disks.
- Support for USB device side mode, also called USB gadget mode,
using the same API like the USB host side. In other words the new
USB stack is symmetric with regard to host and device side.
- Support for USB transfers like I/O vectors, means more throughput
and less interrupts.
- ... see the FreeBSD quarterly status reports under "USB project"

2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.
2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.

Also: Change the initialisation of the command string to a static
initialiser. Verify it against the output of umass.c when being sent a
command using 'camcontrol eject da0' to a Bulk-Only device.
This should make those devices work that need a SCSI eject command to
switch to modem mode (Novatel 950D and others).
allocating resources to read the CIS. I'm not sure when this changed,
but it is totally wrong. Also, add a minor improvement to the
debugging.
This should help everybody trying to run dumpcis on atheros wireless
card as well.

right... Good thing the size was ignored...
Where this macro is used, there's no reason to do it anyway. There
seems to have been some old-time confusion between the CIS pointer
definition, and the BAR definitions at the base of this bug.
compiled into the main AMR driver. It's code that is nice to have but not
required for normal operation, and it is reported to cause problems for some
people.
For an unknown reason the touch pad of my PowerBook generates button 5
events when you operate it. This causes the adb_mouse code to convert
them to button 2 events, which is not what we want.
Add a new flag, AMS_TOUCHPAD, which is used to distinguish the touch
pad. When set, don't convert button events of unknown buttons to the
last button.
There are still three problems left with respect to user input:
- The mouse button events are not properly processed when the touch pad
isn't touched.
- The arrow keys on the keyboard don't work inside X11.
- The power button isn't handled by the kernel, similar to the ACPI
power button on i386/amd64.

use process ID as ACPI thread ID. Concurrent requests with equal thread
IDs broke ACPI mutexes operation causing unpredictable errors including
AE_AML_MUTEX_NOT_ACQUIRED that I have seen.
Use kernel thread ID instead of process ID for ACPI thread.
Right now ams_read() uses cv_wait() to wait for new data to arrive on
the mouse device. This means that when you run `cat /dev/ams0', it
cannot be interrupted directly. After you press ^C, you first need to
move the mouse before cat will quit. Make this function use
cv_wait_sig(), which allows it to be interrupted directly.

capabilities reported by the ap. These need to be cross-checked
against the local configuration in the vap. Previously we were
only checking the ap capabilities which meant that if an ap reported
it was ff-capable but we were not setup to use them we'd try to do
ff aggregation and drop the frame.
There are a number of problems to be fixed here but applying this
fix immediately as the problem causes all traffic to stop (and has
not workaround).

making the use of sc_hwmap to do direct mapping impractical. Switch to
indexing by the rate index instead of the rate code and adjust associated
state and logic appropriately. This has several benefits including
simplification of the led code.
