5022f21bd9 amdsbwd: new driver for AMD SB600/SB7xx watchdog timer
The hardware is compliant with WDRT specification, so I originally
considered including generic WDRT watchdog support, but decided
against it, because I couldn't find anyone to the code for me.
WDRT seems to be not very popular.
Besides, generic WDRT porbably requires a slightly different driver
approach.

d7e7c660b4 Early-generation touchpads do not send periodic calibration frames for
baseline subtraction, and are very temperature sensitive, so would slowly
drift out of a calibrated state when under load. Escape this by taking
the last frame before we decide that the pad is idle as a finger-free
baseline.

30f57f615b Reduce status block size DMAed by controller. bge(4) uses single
Tx/Rx/Rx return ring such that large part of status block was not
used at all. All bge(4) controllers except BCM5700 AX/BX has a
feature to control the size of status block. So use minimum status
block size allowed in controller. This reduces number of DMAed
status block size to 32 bytes from 80 bytes.

ca3f1187f1 Implement TSO for BCM5755 or newer controllers. Some controllers
seem to require a special firmware to use TSO. But the firmware is
not available to FreeBSD and Linux claims that the TSO performed by
the firmware is slower than hardware based TSO. Moreover the
firmware based TSO has one known bug which can't handle TSO if
ethernet header + IP/TCP header is greater than 80 bytes. The
workaround for the TSO bug exist but it seems it's too expensive
than not using TSO at all. Some hardwares also have the TSO bug so
limit the TSO to the controllers that are not affected TSO issues
(e.g. 5755 or higher).
While I'm here set VLAN tag bit to all descriptors that belengs to
a frame instead of the first descriptor of a frame. The datasheet
is not clear how to handle VLAN tag bit but it worked either way in
my testing. This makes it simplify TSO configuration a little bit.

Big thanks to davidch@ who sent me detailed TSO information.
Without this I was not able to implement it.

f681b29a6d Fix two long standing bugs on bge(4). Most pre BCM5755 controllers
have a DMA bug when buffer address crosses a multiple of the 4GB
boundary(e.g. 4GB, 8GB, 12GB etc). Limit DMA address to be within
4GB address for these controllers. The second DMA bug limits DMA
address to be within 40bit address space. This bug applies to
BCM5714 and BCM5715 and 5708(bce(4) controller). This is not
actually a MAC controller bug but an issue with the embedded PCIe
to PCI-X bridge in the device. So for BCM5714/BCM5715 controllers
also limit the DMA address to be within 40bit address space.
Special thanks to davidch@ who gave me detailed errata information.
I think this change will fix long standing bge(4) instability
issues on systems with more than 4GB memory.

dfe0df9a76 For MSI case, interrupt is not shared and we don't need to force
PCI flush to get correct status block update. Add an optimized
interrupt handler that is activated for MSI case. Actual interrupt
handling is done by taskqueue such that the handler does not
require driver lock for Rx path. The MSI capable bge(4) controllers
automatically disables further interrupt once it enters interrupt
state so we don't need PIO access to disable interrupt in interrupt
handler.

later. Previously bge(4) used to reserve 16 free send BDs after
loading dma maps but hardware just need one reserved send BD. If
prouder index has the same value of consumer index it means the Tx
queue is empty.
While I'm here check IFQ_DRV_IS_EMPTY first to save one lock
operation.

- Overhaul the locking to avoid recursion and add missing locking in a few
  places.
- Don't schedule a task to call vge_start() from contexts that are safe to
  call vge_start() directly.  Just invoke the routine directly instead
  (this is what all of the other NIC drivers I am familiar with do).  Note
  that vge(4) does not use an interrupt filter handler which is the primary
  reason some other drivers use tasks.
- Add a new private timer to drive the watchdog timer instead of using

71098608fc Several fixes to these drivers. Note that these two drivers are actually
just two different attachments (EISA and PCI) to a single driver.
- Add real locking.  Previously these drivers only acquired their lock
  in their interrupt handler or in the ioctl routine (but too broadly in
  the latter).  No locking was used for the stack calling down into the
  driver via if_init() or if_start(), for device shutdown or detach.  Also,
  the interrupt handler held the driver lock while calling if_input().  All
  this stuff should be fixed in the locking changes.
- Really fix these drivers to handle if_alloc().  The front-end attachments
  were using if_initname() before the ifnet was allocated.  Fix this by
  moving some of the duplicated logic from each driver into pdq_ifattach().
  While here, make pdq_ifattach() return an error so that the driver just
  fails to attach if if_alloc() fails rather than panic'ing.  Also, defer
  freeing the ifnet until the driver has stopped using it during detach.
- Add a new private timer to drive the watchdog timer.
- Pass the softc pointer to the interrupt handlers instead of the device_t
  so we can avoid the use of device_get_softc() and to better match what
  other drivers do.

d4e576c497 - This driver used the if_watchdog timer both as a watchdog on transmit and
auto-negotiation.  To make this simpler and easier to understand I have
  split this out into two separate timers.  One just manages the auto-neg
  side of things and one is a transmit watchdog.  Neither uses if_watchdog.

- Add a missing callout_drain() to detach.
- Hook into the stats timer and use that to drive the transmit watchdog
  instead of using if_watchdog.
- Run the stats timer every second to match other drivers instead of every
  other second.
- Remove dubious callout handling that stopped the timer only to start it
  again while holding the driver lock without dropping it in between the
  stop and the start.

3d32c12abf Always use a private timer instead of if_watchdog and if_timer to drive
the transmit watchdog.  These drivers already used a private timer when
compiled to use Netgraph.  This change just makes them always use the
private timer.  Note that these drivers do not compile and are disconnected
from the build due to TTY changes.

b1f459a01b Use a private callout timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.  The driver already contained an optional stats
timer that individual attachments could use to provide a 'tick' event.  The
stats timer only ran if the tick function pointer was non-NULL and the
attachment's tick routine had to call callout_reset(), etc.  Now the driver
always schedules a stat timer and manages the callout_reset() internally.
This timer is used to drive the watchdog and will also call the attachment's
'tick' handler if one is provided.

6bd8779bb9 Change the way in which AHCI+PATA combined controllers, such as JMicron
and Marvell handled. Instead of trying to attach two different drivers to
single device, wrapping each call, make one of them (atajmicron, atamarvell)
attach do device solely, but create child device for AHCI driver,
passing it all required resources. It is quite easy, as none of
resources are shared, except IRQ.

As result, it:
- makes drivers operation more independent and straitforward,
- allows to use new ahci(4) driver with such devices, adding support for
new features, such as PMP and NCQ, same time keeping legacy PATA support,
- will allow to just drop old ataahci driver, when it's time come.

4b2361f811 Convert syscons on i386 to TERM=xterm.
TEKEN_XTERM is now gone. Because we always use xterm mode now, we only

e42fc36867 Switch the default terminal emulation style to xterm for most platforms.
Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:

- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
  regions.
- A very hard transition path to support for modern character sets like
  UTF-8.

Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.

I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.

IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):

- Run the application inside script(1), try to reduce the problem and
  send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
  TERM=cons25' so you can run applications the same way you did before.
  You can also build your kernel with `options TEKEN_CONS25' to make all
  virtual terminals use the cons25 emulator by default.

68c4dfdf0c Make isa_dma functions MPSAFE by introducing its own private lock. These
functions are selfcontained (ie. they touch only isa_dma.c static variables
and hardware) so a private lock is sufficient to prevent races. This changes
only i386/amd64 while there are also isa_dma functions for ia64/sparc64.
Sparc64 are ones empty stubs and ia64 ones are unused as ia64 does not
have isa (says marcel).

This patch removes explicit locking of Giant from a few drivers (there
are some that requires this but lack ones - this patch fixes this) and
also removes the need for implicit locking of Giant from attach routines
where it's provided by newbus.

30b22abe40 Integrate lost interrupts patch from the old USB stack.
Some EHCI chips from VIA / ATI seem to trigger interrupts before writing back
the qTD status, or miss signalling occasionally under heavy load.  If the host
machine is too fast, we can miss transaction completion - when we scan the
active list the transaction still seems to be active. This generally exhibits
itself as a umass stall that never recovers.

We work around this behaviour by setting up this callback after any softintr
that completes with transactions still pending, giving us another chance to
check for completion after the writeback has taken place

761eeb5fff Fix VESA color palette corruption:
- VBE 3.0 says palette format resets to 6-bit mode when video mode changes.
We simply set 8-bit mode when we switch modes if the adapter supports it.
- VBE 3.0 also says if the mode is not VGA compatible, we must use VBE
function to save/restore palette.  Otherwise, VGA function may be used.
Thus, reinstate the save/load palette functions only for non-VGA compatible
modes regardless of its palette format.
- Let vesa(4) set VESA modes even if vga(4) claims to support it.
- Reset default palette if VESA pixel mode is set initially.
- Fix more style nits.

- Rework timeout handling, to make it more graceful for devices sharing
controller port (with PMP). Wait for other commands completion/timeout
before initiating recovery.
- Handle timeouts and fatal errors with port hard-reset. The rest of
recovery will be done by XPT on receiving async event. More gracefull
per-device soft-reset recovery can be implemented later.

Most of the pieces came from Marius- correct settings for channels

5b6d1d9d08 Add a check to know whether driver is still running after
reacquiring driver lock in Rx handler. re(4) drops a driver lock
before passing received frame to upper stack and reacquire the
lock. During the time window ioctl calls could be executed and if
the ioctl was interface down request, driver will stop the
controller and free allocated mbufs. After that when driver comes
back to Rx handler again it does not know what was happend so it
could access free mbufs which in turn cause panic.

7bcfccda40 While certain supported Symbios/LSI SCSI chips (532c896, 53c1000, 53c1010)
do support 64bit addresses, the current SCRIPTS code supports only 32bit
addresses causing data corruption for buffer addresses >4GB. This problem
affects 64bit machines with more than 4GB RAM or amd64 with 4GB and
memory hole remapping.
Work-around this problem with a bus_dma tag that requests bounce-buffers
for addresses >4GB. This causes some overhead, but given the maximum SCSI
bus speed of 160MB/s compared, the effect should hardly be noticeable.
The problem was reported by Mike Watters (mike at mwatters net) who also
verified that this fix cures the problem.

Since this change is a NOOP on systems with less than 4GB RAM and fixes
data corruption (in RAM and on disk) on systems with more than 4GB, I hope
that this change is accepted for 8.0.

f3755df16d Turn off use of ATA_A_4BIT on modern hardware. This flag was already
obsoleted in 1996 by ATA-2, and crashes some modern hardware like some
revisions of the Serverworks K2 SATA controller. Even very ancient
hardware seems not to require it. In the unlikely event this causes
problems, the previous behavior can be re-enabled by defining
ATA_LEGACY_SUPPORT at the top of this file.
