- Correct RX packet drop counter for BCM5705+. This register is read/clear
and it wraps very quickly under heavy packet drops because only the lower
ten bits are valid according to the documentation. However, it seems few
more bits are actually valid and the rest bits are always zeros[1].
Therefore, we don't mask them off here. To get accurate packet drop count,
we need to check the register from bge_rxeof(). It is commented out for now,
not to penalize normal operation. Actual performance impact should be
measured later.
- Correct integer casting from u_long to uint32_t. Casting is not really
needed for all supported platforms but we better do this correctly[2].

- In hme_eint() print MIF register contents on MIF interrupts.
- In hme_mifinit() don't bother to preserve the previous MIF config.
This was mainly done in order to preserve the PHY select bit (external
or internal PHY) but which only needs to be set as appropriate when
reading from or writing to the desired PHY in hme_mii_{read,write}reg().
Similarly don't bother to set the PHY select bit in hme_mii_statchg().
- In hme_mii_{read,write}reg() ignore requests to PHYs other than the
external and internal PHY one.
- Move enabling/disabling the MII drivers of the external transceiver
from hme_init_locked() and based on the sheer presence of an external
to hme_mifinit() and based on the currently selected media, defaulting
to the internal transceiver when the media hasn't been set, yet.
Invoke hme_mifinit() from the newly added hme_mediachange_locked() so
the setting of the MII drivers is updated when changing media.
These changes keep the MII bus from wedging (which manifests in the HME
and the PHYs no longer being able to communicate with each other) when
the PHY device drivers isolate the unused PHY in two-PHY configurations
as present in f.e. Netra t1 100 while changing media, either from
hme_init_locked() (see also below) or via ifconfig(8). They also allow
for using both transceivers/PHYs.
- In the newly added hme_mediachange_locked() also reset the PHYs in two-
PHY configurations before invoking mii_mediachg(). This is required
for successfully unisolating the previously unused PHY when switching
between PHYs.
- Now that changing media should no longer cause problems back out rev.

the commit message of rev. 1.23 for more info).

- Multichannel safe, endian safe, format safe
* Large part of critical pcm filters such as vchan.c, feeder_rate.c,
feeder_volume.c, feeder_fmt.c and feeder.c has been rewritten so that
using them does not cause the pcm data to be converted to 16bit little
endian.
* Macrosses for accessing pcm data safely are defined within sound.h in
the form of PCM_READ_* / PCM_WRITE_*
* Currently, most of them are probably limited for mono/stereo handling,
but the future addition of true multichannel will be much easier.
- Low latency operation
* Well, this require lot more works to do not just within sound driver,
but we're heading towards right direction. Buffer/block sizing within
channel.c is rewritten to calculate precise allocation for various
combination of sample/data/rate size. As a result, applying correct
SNDCTL_DSP_POLICY value will achive expected latency behaviour simmilar
to what commercial 4front driver do.
* Signal handling fix. ctrl+c of "cat /dev/zero > /dev/dsp" does not
result long delay.
* Eliminate sound truncation if the sound data is too small.

it is used for transfers that move data from USB to PC. But

data chunks : the request itself and optionally a buffer of

requests to the control endpoint without additional data
bus_dmamap_sync() didn't get called. For some reason my first

- Add 3 new functions to the pci_if interface along with suitable wrappers
to provide the device driver visible API:
- pci_alloc_msi(dev, int *count) backed by PCI_ALLOC_MSI(). '*count'
here is an in and out parameter. The driver stores the desired number
of messages in '*count' before calling the function. On success,
'*count' holds the number of messages allocated to the device. Also on
success, the driver can access the messages as SYS_RES_IRQ resources
starting at rid 1. Note that the legacy INTx interrupt resource will
not be available when using MSI. Note that this function will allocate
either MSI or MSI-X messages depending on the devices capabilities and
the 'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. Also note
that the driver should activate the memory resource that holds the
MSI-X table and pending bit array (PBA) before calling this function
if the device supports MSI-X.
- pci_release_msi(dev) backed by PCI_RELEASE_MSI(). This function
releases the messages allocated for this device. All of the
SYS_RES_IRQ resources need to be released for this function to succeed.
- pci_msi_count(dev) backed by PCI_MSI_COUNT(). This function returns
the maximum number of MSI or MSI-X messages supported by this device.
MSI-X is preferred if present, but this function will honor the
'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. This function
should return the largest value that pci_alloc_msi() can return
(assuming the MD code is able to allocate sufficient backing resources
for all of the messages).
- Add default implementations for these 3 methods to the pci_driver generic
PCI bus driver. (The various other PCI bus drivers such as for ACPI and
OFW will inherit these default implementations.) This default
implementation depends on 4 new pcib_if methods that bubble up through
the PCI bridges to the MD code to allocate IRQ values and perform any
needed MD setup code needed:
- PCIB_ALLOC_MSI() attempts to allocate a group of MSI messages.
- PCIB_RELEASE_MSI() releases a group of MSI messages.
- PCIB_ALLOC_MSIX() attempts to allocate a single MSI-X message.
- PCIB_RELEASE_MSIX() releases a single MSI-X message.
- Add default implementations for these 4 methods that just pass the
request up to the parent bus's parent bridge driver and use the
default implementation in the various MI PCI bridge drivers.
- Add MI functions for use by MD code when managing MSI and MSI-X
interrupts:
- pci_enable_msi(dev, address, data) programs the MSI capability address
and data registers for a group of MSI messages
- pci_enable_msix(dev, index, address, data) initializes a single MSI-X
message in the MSI-X table
- pci_mask_msix(dev, index) masks a single MSI-X message
- pci_unmask_msix(dev, index) unmasks a single MSI-X message
- pci_pending_msix(dev, index) returns true if the specified MSI-X
message is currently pending
- Save the MSI capability address and data registers in the pci_cfgreg
block in a PCI devices ivars and restore the values when a device is
resumed. Note that the MSI-X table is not currently restored during

keyboard ID and verify at its invocation in sunkbd_configure() that we're
talking to a Sun type 4/5/6 keyboard, i.e. a keyboard supported by this
driver.
- Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective
code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to
emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by
kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also
triggers the use of AT keyboard maps and thus allows to use the map files
in share/syscons/keymaps with this driver at the cost of an additional
translation (in ukbd(4) this just is the way of operation).
- Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options
of the other keyboard drivers allows to specify the default in-kernel
keyboard map. For obvious reasons this made to only work when also using
SUNKBD_EMULATE_ATKBD.
- Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(),
which are also required for interoperability with kbdmux(4).
- Implement K_CODE mode and FreeBSD keypad compose.
- As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD
case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than
having to duplicate it and #ifdef some more code.
- Don't use the TX-buffer for writing the two command bytes for setting the
keyboard LEDs as this consequently requires a hardware FIFO that is at
least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't
have. Thus use an inlined version of uart_putc() to consecutively write
the command bytes (a cleaner approach would be to do this via the soft
interrupt handler but that variant wouldn't work while in ddb(4)). [1]

keyboard is attached only after the system has already booted.
If USB keyboard is also present, and there's no kbdmux(4), the problem
has been hiding itself because as soon as we get to multi-user, the
USB keyboard becomes an active keyboard (see devd.conf), thus marking
atkbd inactive and letting the old code initialize the keyboard.
With kbdmux(4), or if there's no USB keyboard, the atkbd keyboard is
always active, whether it's physically attached or not, thus it never
initialized itself properly on a physical attach.
To fix this, move block that initialized the keyboard on attach upper
so it doesn't depend on the (KBD_IS_ACTIVE(kbd) && KBD_IS_BUSY(kbd))
condition. Also move KBD_FOUND_DEVICE() a few lines upper so that
KDSETLED and KDSETREPEAT that follow it propagate to the controller.

just allocate the resource and check its size. This also pointed out that

The goal was to sync with the OSSv4 API 4Front Technologies uses in their
proprietary OSS driver. This was successful as far as possible. The part
of the API which is stable is implemented, for the rest there are some
stubs already.
New system ioctls:
- SNDCTL_SYSINFO - obtain audio system info (version, # of audio/midi/
mixer devices, etc.)
- SNDCTL_AUDIOINFO - fetch details about a specific audio device
- SNDCTL_MIXERINFO - fetch details about a specific mixer device
New audio ioctls:
- Sync groups (SNDCTL_DSP_SYNCGROUP/SNDCTL_DSP_SYNCSTART) which allow
triggered playback/recording on multiple devices (even across processes
simultaneously).
- Peak meters (SNDCTL_DSP_GETIPEAKS/SNDCTL_DSP_GETOPEAKS) - can query
audio drivers for peak levels (needs driver support, disabled for now).
- Per channel playback/recording levels -
SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL. Note that these are still in name
only, just wrapping around the AC97-style mixer at the moment. The next
step is to push them down to the drivers.
Audio ioctls still under development by 4Front (for which stubs may exist
in this commit):
- SNDCTL_GETNAME, SNDCTL_{GET,SET}{SONG,LABEL}
- SNDCTL_DSP_{GET,SET}_CHNORDER
- SNDCTL_MIX_ENUMINFO, SNDCTL_MIX_EXTINFO - (might be documented enough in
the OSS releases to work on this. These ioctls cover the cool "twiddle
any knob on your card" features.)
Missing:
- SNDCTL_DSP_COOKEDMODE -- this ioctl is used to give applications direct
access to a card's buffers, bypassing the feeder architecture. It's
a toughy -- "someone" needs to decide :
(a) if this is desireable, and (b) if it's reasonably feasible.
Updates for driver writers:
So far, only two routines to the channel class (in channel_if.m) are added.
One is for fetching a list of discrete supported playback/recording rates
of a channel, and the other is for fetching peak level info (useful for
drawing peak meters). Interested parties may want to help pushing down
SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL into the drivers.

Requested by: imp
- Change smbus_callback() to pass a void * rather than caddr_t.
- Change smbus_bread() to pass a pointer to the count and have it be an
in/out parameter. The input is the size of the buffer (same as before),
but on return it will contain the actual amount of data read back from
the bus. Note that this value may be larger than the input value. It
is up to the caller to treat this as an error if desired.
- Change the SMB_BREAD ioctl to write out the updated struct smbcmd which
will contain the actual number of bytes read in the 'count' field. To
preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD
which doesn't copy the updated smbcmd back out to userland. I doubt anyone
actually used the old BREAD anyway as it was rediculous to do a bulk-read
but not tell the using program how much data was actually read.
- Make the smbus driver and devclass public in the smbus module and
push all the DRIVER_MODULE()'s for attaching the smbus driver to
various foosmb drivers out into the foosmb modules. This makes all
the foosmb logic centralized and allows new foosmb modules to be
self-contained w/o having to hack smbus.c everytime a new smbus driver
is added.
- Add a new SMB_EINVAL error bit and use it in place of EINVAL to return
an error for bad arguments (such as invalid counts for bread and bwrite).
- Map SMB bus error bits to EIO in smbus_error().
- Make the smbus driver call bus_generic_probe() and require child drivers
such as smb(4) to create device_t's via identify routines. Previously,
smbus just created one anonymous device during attach, and if you had
multiple drivers that could attach it was just random chance as to which
driver got to probe for the sole device_t first.
- Add a mutex to the smbus(4) softc and use it in place of dummy splhigh()
to protect the 'owner' field and perform necessary synchronization for
smbus_request_bus() and smbus_release_bus().
- Change the bread() and bwrite() methods of alpm(4), amdpm(4), and
viapm(4) to only perform a single transaction and not try to use a
loop of multiple transactions for a large request. The framing and
commands to use for a large transaction depend on the upper-layer
protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the
smb(4) driver never allowed bulk read/writes of more than 32-bytes
anyway. The other smb drivers only performed single transactions.
- Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4),
amdpm(4), amdsmb(4), intpm(4), and nfsmb(4).
- Use SMB_xxx errors in viapm(4).

additional parameter (relative to pmap_mapdev()) specifying the cache
mode for this mapping. Note that on amd64 only WB mappings are done with
the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
mappings rather than WB. Previously we relied on the BIOS setting up
MTRR's to enforce memio regions being treated as UC. This might make
hw.cbb_start_memory unnecessary in some cases now for example.

- Change the workaround for the autopad/checksum offload bug so that

This approach also gives us a chance to zero the pad space to avoid

- With the PCIe devices, it looks issuing a TX command while there's
already a transmission in progress doesn't have any effect. In other
words, if you send two packets in rapid succession, the second one may
end up sitting in the TX DMA ring until another transmit command is
issued later in the future. Basically, if re_txeof() sees that there
are still descriptors outstanding, it needs to manually resume the
TX DMA channel by issuing another TX command to make sure all
transmissions are flushed out. (The PCI devices seem to keep the
TX channel moving until all descriptors have been consumed. I'm not
sure why the PCIe devices behave differently.)
(You can see this issue if you do the following test: plug an re(4)
interface into another host via crossover cable, and from the other
host do 'ping -c 2 <host with re(4) NIC>' to prime the ARP cache,
then do 'ping -c 1 -s 1473 <host with re(4) NIC>'. You're supposed
to see two packets sent in response, but you may only see one. If
you do 'ping -c 1 -s 1473 <host with re(4) NIC>' again, you'll
see two packets, but one will be the missing fragment from the last
ping, followed by one of the fragments from this ping.)
- Add the PCI ID for the US Robotics 997902 NIC, which is based on
the RTL8169S.
- Add a tsleep() of 1 second in re_detach() after the interrupt handler
is disconnected. This should allow any tasks queued up by the ISR
to drain. Now, I know you're supposed to use taskqueue_drain() for
this, but something about the way taskqueue_drain() works with
taskqueue_fast queues doesn't seem quite right, and I refuse to be
tricked into fixing it.
- Correct the PCI ID for the 8169SC/8110SC in the device list (I added
the macro for it to if_rlreg.h before, but forgot to use it.)
- Remove the extra interrupt spinlock I added previously. After giving it
some more thought, it's not really needed.
- Work around a hardware bug in some versions of the 8169. When sending
very small IP datagrams with checksum offload enabled, a conflict can
occur between the TX autopadding feature and the hardware checksumming
that can corrupt the outbound packet. This is the reason that checksum
offload sometimes breaks NFS: if you're using NFS over UDP, and you're
very unlucky, you might find yourself doing a fragmented NFS write where
the last fragment is smaller than the minimum ethernet frame size (60
bytes). (It's rare, but if you keep NFS running long enough it'll
happen.) If checksum offload is enabled, the chip will have to both
autopad the fragment and calculate its checksum header. This confuses
some revs of the 8169, causing the packet that appears on the wire
to be corrupted. (The IP addresses and the checksum field are mangled.)
This will cause the NFS write to fail. Unfortunately, when NFS retries,
it sends the same write request over and over again, and it keeps
failing, so NFS stays wedged.
(A simple way to provoke the failure is to connect the failing system
to a network with a known good machine and do "ping -s 1473 <badhost>"
from the good system. The ping will fail.)
Someone had previously worked around this using the heavy-handed
approahch of just disabling checksum offload. The correct fix is to
manually pad short frames where the TCP/IP stack has requested
checksum offloading. This allows us to have checksum offload turned
on by default but still let NFS work right.

mac-io bus, we cannot setup FAST interrupt handlers. This because we
use spinlocks to protect the hardware and all interrupt resources are
assigned the same interrupt handler. When the interrupt handler is
invoked for interrupt X, it could be preempted for interrupt Y while
it was holding the lock (where X and Y are the interrupt resources
corresponding a single instance of this driver). This is a deadlock.
By only using a MPSAFE handler in that case we prevent preemption.

instead of doing the first load with the BUS_DMA_NOWAIT flag. On 4.x with
PAE and > 4gb of RAM this proved disastrous if there weren't enough bounce
pages as amr_mapcmd() would return failure but the callback would later
fire once enough bounce pages were available and would then overwrite
another command's S/G list.

out ELS buffers but *don't* hang out commands,

If we add command buffers, we have to respond to

forcing all transfers to do the start read/write stop by hand. Some
smart bridges prefer this sort of operation, and this allows us to
support their features more easily. When bridges don't support it, we
fall back to using the old-style opertaions. Expand the ioctl
interface to expose this function. Unlike the old-style interface,
this interface is thread safe, even on old bridges.
Add MEMORY_BARRIER for the few scratch dma ops that were missing

install custom pager functions didn't actually happen in practice (they
all just used the simple pager and passed in a local quit pointer). So,
just hardcode the simple pager as the only pager and make it set a global
db_pager_quit flag that db commands can check when the user hits 'q' (or a
suitable variant) at the pager prompt. Also, now that it's easy to do so,
enable paging by default for all ddb commands. Any command that wishes to
honor the quit flag can do so by checking db_pager_quit. Note that the
pager can also be effectively disabled by setting $lines to 0.
Other fixes:
- 'show idt' on i386 and pc98 now actually checks the quit flag and
terminates early.
- 'show intr' now actually checks the quit flag and terminates early.

Put back role setting into mpt. That is, you can set a desired role
for mpt as a hint. On the next reboot, it'll pick that up and redo
the NVRAM settings appropriately and warn you that this won't take
effect until the next reboot. This saves people the step of having
to find a BIOS utilities disk to set target and/or initiator role
for the MPT cards.
significantly reduces booting time when there is broken floppy disk drive,
controller, cable, BIOS, etc.
When the floppy controller interface is correctly implemented, disk change
signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.
However, there are many cases that the signal is unusable. Moreover, some
BIOS does not reserve the port at all. In those cases, the register may not
function.
loading for the QLogic cards.
Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.
However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.
For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.
This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.
We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).
Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

Use it to reset controller and to select data rate. According to Intel
80277AA datasheet, software reset behaves the same as DOR reset except
that it is self clearing. National Semiconductor PC8477B datasheet says
the same. As a side effect, we no longer use Configuration Control
Register (CCR) at 0x3f7 for these controllers, which is often missing
in modern hardware.

One peculiar thing I've found with the 2322 is that if you
don't force it to do Hard LoopID acquisition, the firmware
crashes. This took a while to figure out.

tree... John Baldwin noted that sio might pass values between probe
and attach via softc. It appears that sio does leave the hardware in
a known state after probing, so other drivers that try to probe might
leave it in a worse state. It doesn't seem to pass any data in softc,
however, that I could find... I think we should not be probing for
anything but nonPnP isa, but that's a change for another day.

cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.
There are two possible reasons for there to be two different HWREVs:
1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
and the 8111B/8168B both use 0x38000000.
The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.
So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings

latter is a PCIe 10/100 chip.
Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.
Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.
Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.
Make the re_diag() routine conditional and off by default. When it is
on, only use it for the original 8169, which was the only device that
that really needed it.
Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.
Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.
Make the rgephy driver advertise both 1000_FD and 1000_HD bits in
autoneg mode. A couple of the devices don't autoneg correctly unless
configured this way.
