Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
needs different handling than the integrated ones in terms of
speed detection. There was a bogus test based on the parent
device driver name string controlling which speed register to
query. That test began failing when the rl driver was split into
separate rl and re drivers some time ago. Apparently nobody ever
noticed because the buggy code only executes if NWAY negotiation
failed. Since we happen to be testing with an ancient dumb hub
rather than a modern switch, we found it.
To fix it all, have the attach() routine notice whether we're
dealing with an integrated PHY or an RTL8201L and store that info
in a struct accessible to the status() routine that needs to know
which register to query.
I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

To fix this, we avoid software padding for short TCP segments, since

- First off, device drivers really do need to know if they are allocating
MSI or MSI-X messages. MSI requires allocating powerof2() messages for
example where MSI-X does not. To address this, split out the MSI-X
support from pci_msi_count() and pci_alloc_msi() into new driver-visible
functions pci_msix_count() and pci_alloc_msix(). As a result,
pci_msi_count() now just returns a count of the max supported MSI
messages for the device, and pci_alloc_msi() only tries to allocate MSI
messages. To get a count of the max supported MSI-X messages, use
pci_msix_count(). To allocate MSI-X messages, use pci_alloc_msix().
pci_release_msi() still handles both MSI and MSI-X messages, however.
As a result of this change, drivers using the existing API will only
use MSI messages and will no longer try to use MSI-X messages.
- Because MSI-X allows for each message to have its own data and address
values (and thus does not require all of the messages to have their
MD vectors allocated as a group), some devices allow for "sparse" use
of MSI-X message slots. For example, if a device supports 8 messages
but the OS is only able to allocate 2 messages, the device may make the
best use of 2 IRQs if it enables the messages at slots 1 and 4 rather
than default of using the first N slots (or indicies) at 1 and 2. To
support this, add a new pci_remap_msix() function that a driver may call
after a successful pci_alloc_msix() (but before allocating any of the
SYS_RES_IRQ resources) to allow the allocated IRQ resources to be
assigned to different message indices. For example, from the earlier
example, after pci_alloc_msix() returned a value of 2, the driver would
call pci_remap_msix() passing in array of integers { 1, 4 } as the
new message indices to use. The rid's for the SYS_RES_IRQ resources
will always match the message indices. Thus, after the call to
pci_remap_msix() the driver would be able to access the first message
in slot 1 at SYS_RES_IRQ rid 1, and the second message at slot 4 at
SYS_RES_IRQ rid 4. Note that the message slots/indices are 1-based
rather than 0-based so that they will always correspond to the rid
values (SYS_RES_IRQ rid 0 is reserved for the legacy INTx interrupt).
To support this API, a new PCIB_REMAP_MSIX() method was added to the
pcib interface to change the message index for a single IRQ.

The separate bus front-end was inherited from the OpenBSD creator(4),
which at that time had a mainbus(4) (for USI/II machines, which use
an UPA interconnection bus as the nexus) and an upa(4) (for USIII
machines, which use a subordinate/slave UPA bus hanging off from the
Fireplane/Safari interconnection bus) front-end. With FreeBSD and
newbus there is/will be no need to have two separate bus front-ends
for these busses, so we can easily coallapse the shared front-end
and the back-end into a single source file (note that the FreeBSD
creator_upa.c was misnomer anyway; based on what it actually attached
to that should have been creator_nexus.c), actually OpenBSD meanwhile
also has moved to a shared front-end and a single source file. Due
to the low-level console support creator.c also wasn't free from bus
related things before.
While at it, also split sys/sparc64/creator/creator.h into a
sys/dev/fb/creatorreg.h that only contains register macros and move
the structures to the top of sys/dev/fb/creator.c as suggested by
style(9) so creator(4) is no longer scattered over two directories.
- Use OF_decode_addr()/sparc64_fake_bustag() to obtain the bus tags and
handles for the low-level console support instead of hardcoding
support for AFB/FFB hanging off from nexus(4) only. This is part 2/4
of allowing creator(4) to work in USIII machines (which have a UPA
bus hanging off from the Fireplane/Safari bus reflected by the nexus),
which already makes it work as the low-level console there.
- Allocate resources in the bus attach routine regardless of whether
creator(4) is used as for the low-level console and thus the required
bus tags and handles have been already obtained or not so the resources
are marked as taken in the respective RMAN.
- For both obtaining the bus tags and handles for the low-level console
support as well as allocating the corresponding resources in the
regular bus attach routine don't bother to get all for the maximum of
24 register banks but only (for) the two tag/handle pairs required for
providing the video interface for syscons(4) support. If we can't
allocate the rest of them just limit the memory range accessible via
creator_fb_mmap() accordingly.
- Sanity check the memory range spanned by the first and last resources
and the resources in between as far as possible, as the XFree86/Xorg
sunffb(4) expects to be able to access the whole region, even though
the backing resources are actually non-continuous. Limit and check
the memory range accessible via creator_fb_mmap() accordingly.
- Reduce the size of buffers for OFW properties to what they actually
need to hold.
- Rename some tables to creator_<foo> for consistency.
- Also for the sizes in the creator_fb_mmap() mapping table entries use
macros for consistency, add macros for the remaining register banks
for completeness.
operation as it ran out of free descriptors or if there are too many
segments in the first place, call bus_dmamap_unload() in order to
unload the already loaded segments.
For trying to map the defragmented mbuf (chain) in re_encap() this
introduces re_dma_map_desc() setting arg.rl_maxsegs to 0 as a new
failure mode. Previously we just ignored this case, corrupting our
view of the TX ring.
o In re_txeof():
- Don't clear IFF_DRV_OACTIVE unless there are at least 4 free TX
descriptors. Further down the road re_encap() will bail if there
aren't at least 4 free TX descriptors, causing re_start() to
abort and prepend the dequeued mbuf again so it makes no sense
to pretend we could process mbufs again when in fact we won't.
While at it replace this magic 4 with a macro RL_TX_DESC_THLD
throughout this driver.
- Don't cancel the watchdog timeout as soon as there's at least one
free TX descriptor but instead only if all descriptors have been
handled. It's perfectly normal, especially in the DEVICE_POLLING
case, that re_txeof() is called when only a part of the enqueued
TX descriptors have been handled, causing the watchdog to be
disarmed prematurely.
o In re_encap():
- If m_defrag() fails just drop the packet like other NIC drivers
do. This should only happen when there's a mbuf shortage, in which
case it was possible to end up with an IFQ full of packets which
couldn't be processed as they couldn't be defragmented as they
were taking up all the mbufs themselves. This includes adjusting
re_start() to not trying to prepend the mbuf (chain) if re_encap()
has freed it.
- Remove dupe initialization of members of struct rl_dmaload_arg to
values that didn't change since trying to process the fragmented
mbuf chain.
While at it remove an unused member from struct rl_dmaload_arg.
o In re_start() remove a abandoned, banal comment. The corresponding
code was moved to re_attach() some time ago.
With these changes re(4) now survives one day (until stopped) of
hammering out packets here.

- Fixed the case where multiple cpus in the system share the same

The problem was that I was acquiring the driver sx lock and then waiting
for a taskqueue to drain, however the taskqueue itself would try to
acquire the lock as well leading to a deadlock.
To fix the problem roll my own exclusive lock that allows for lock
cancellation. This is a normal exclusive lock, however if someone
marks it as "dead" then all waiters who request an error return will
get back an error instead of continuing to wait for the lock.
In this particular case, the shutdown and detach functions kill the
lock while the async task thread tries to acquire the lock but will
abort if the lock returns an error.
The other option was to drop the driver lock mid-detach and mid-shutdown,
mid-detach was a ok, however mid-shutdown was not.

been handled instead of when at least one descriptor was just handled.
For bge, it is normal to get a txeof when only a small fraction of the
queued tx descriptors have been handled, so the bug broke the watchdog
in a usual case.
- moved the synchronizing bus read to after the bus write for the first
interrupt ack so that it actually synchronizes everything necessary.
We were acking not only the status update that triggered the interrupt
together with any status updates that occurred before we got around
to the bus write for the ack, but also any status updates that occur
after we do the bus write but before the write reaches the device.
The corresponding race for the second interrupt ack resulted in
sometimes returning from the interrupt handler with acked but
unserviced interrupt events. Such events then remain unserviced
until further events cause another interrupt or the watchdog times
out.
The race was often lost on my 5705, apparently since my 5705 has broken
event coalescing which causes a status update for almost every packet,
so another status update is quite likely to occur while the interrupt
handler is running. Watchdog timeouts weren't very noticeable,
apparently because bge_txeof() has one of the usual bugs resetting the
watchdog.
- don't disable device interrupts while bge_intr() is running. Doing this
just had the side effects of:
- entering a device mode in which different coalescing parameters apply.
Different coalescing parameters can be used to either inhibit or
enhance the chance of getting another status update while in the
interrupt handler. This feature is useless with the current
organization of the interrupt handler but might be useful with a
taskqueue handler.
- giving a race for ack+reenable/return. This cannot be handled
by simply rearranging the order of bus accesses like the race for
ack+keepenable/entry. It is necessary to sync the ack and then
check for new events.
- taking longer, especially with the extra code to avoid the race on
ack+reenable/return.

- 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.

- 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.

when the request doesn't include the optional data buffer the size of
the transfer (xfer->length) is 0, in which case usbd_transfer() won't
create a DMA map but call usbd_start_transfer() with no DMA segments.
With the previous change this could result in the bus_dmamap_sync()

argument.

- 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
someone forgot that control transfers consist of possibly two
data chunks : the request itself and optionally a buffer of
data that should be transfered to or from the USB device. On
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
resume.
- Add constants for MSI-X register offsets and fields.
- Record interesting data about any MSI-X capability blocks we come
across in the pci_cfgreg block in the ivars for PCI devices.

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]

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.
