1432824670 Always show asic/chip revision in device attach phase. There are
too many bge(4) controllers there and model name does not
necessarily match asic/chip revision. Relying on VPD string made
it hard to identify exact asic/chip revision so the first step to
debug bge(4) was getting exact asic/chip information with verbose
boot which may not be available on production server.

9c2d052943 acpi_attach: do not explicitly install default handlers for default
address spaces

There has been no need to do that starting with ACPICA 20040427 as
AcpiEnableSubsystem() installs the handlers automatically.
Additionaly, explicitly calling AcpiInstallAddressSpaceHandler before
AcpiEnableSubsystem is not supported by ACPICA and leads to too early
execution of _REG methods in some DSDTs, which may result in problems.

Big thanks to Robert Moore of ACPICA/Intel for explaining the above.

8385f4cf94 Tweak the stats exported by the e1000 drivers:
- Add a single sysctl procedure to all three drivers to read an arbitrary
  register (the register is passed as arg2).  Use it to replace existing
  routines in igb(4) that used a separate routine for each register, and
  to add support for missing stats in em(4) and lem(4).
- Move the 'rx_overruns' and 'watchdog_timeouts' stats out of the MAC stats
  section as they are driver stats, not MAC counters.
- Simplify the code that creates per-queue stats in igb(4) to use a single
  loop and remove duplicated code.
- Properly read all 64 bits of the 'good octets received/transmitted' in
  em(4) and lem(4).
- Actually read the interrupt count registers in em(4), and drop the
  'host to card' sysctl stats from em(4) as they are not implemented in
  any of the hardware this driver supports.
- Restore several stats to em(4) that were lost in the earlier stats
  conversion including per-queue stats.
- Export several MAC stats in em(4) that were exported in igb(4) but not
  in em(4).
- Export stats in lem(4) using individual sysctls as in em(4) and igb(4).

particular edge case where X-axis resolution is not multiple of font width.
Now we just advance enough scan lines, then deduct a partial scan line.

0b883cf6b4 Fix a couple of mps problems.
When the driver is completely saturated with commands (1024 in the
case of the SAS2008 in my test system), I/O stops.  If we tell CAM
that we have one less command slot than we have actually allocated,
everything works fine.  We also need a few extra command slots to
allow for aborts and other task management commands to be sent down.

This needs more investigation to determine the root cause, but for
now this fixes things in my testing.

mps.c:		Change a printf() to mps_printf().

mps_sas.c:	Subtract 5 command slots when we tell CAM how many
		commands we can handle.

		Add some commented-out logic to print the contents
		the CDBs for timed-out commands.  This can help
		in debugging devices that are timing out.  This
		will be uncommented once I bring some CAM changes in.

63feedfd46 MFp4 (//depot/projects/mps/...):
According to the MPT2 spec, task management commands are
serialized, and so no I/O should start while task management
commands are active.

So, to comply with that, freeze the SIM queue before we send any
task management commands (abort, target reset, etc.) down to the
IOC.  We unfreeze the queue once the task management command
completes.

It isn't clear from the spec whether multiple simultaneous task
management commands are supported.  Right now it is possible to
have multiple outstanding task management commands, especially in
the abort case.  Multiple outstanding aborts do complete
successfully, so it may be supported.

We also don't yet have any recovery mechanism (e.g. reset the IOC)
if the task management command fails.

09c22c66e1 acpi_cpu: do not apply P_LVLx_LAT rules to latencies returned by _CST
ACPI specification sates that if P_LVL2_LAT > 100, then a system doesn't
support C2; if P_LVL3_LAT > 1000, then C3 is not supported.
But there are no such rules for Cx state data returned by _CST.  If a
state is not supported it should not be included into the return
package.  In other words, any latency value returned by _CST is valid,
it's up to the OS and/or user to decide whether to use it.

a157e42516 Refactor timer management code with priority to one-shot operation mode.
The main goal of this is to generate timer interrupts only when there is
some work to do. When CPU is busy interrupts are generating at full rate
of hz + stathz to fullfill scheduler and timekeeping requirements. But
when CPU is idle, only minimum set of interrupts (down to 8 interrupts per
second per CPU now), needed to handle scheduled callouts is executed.
This allows significantly increase idle CPU sleep time, increasing effect
of static power-saving technologies. Also it should reduce host CPU load
on virtualized systems, when guest system is idle.

There is set of tunables, also available as writable sysctls, allowing to
control wanted event timer subsystem behavior:
  kern.eventtimer.timer - allows to choose event timer hardware to use.
On x86 there is up to 4 different kinds of timers. Depending on whether
chosen timer is per-CPU, behavior of other options slightly differs.
  kern.eventtimer.periodic - allows to choose periodic and one-shot
operation mode. In periodic mode, current timer hardware taken as the only
source of time for time events. This mode is quite alike to previous kernel
behavior. One-shot mode instead uses currently selected time counter
hardware to schedule all needed events one by one and program timer to
generate interrupt exactly in specified time. Default value depends of
chosen timer capabilities, but one-shot mode is preferred, until other is
forced by user or hardware.
  kern.eventtimer.singlemul - in periodic mode specifies how much times
higher timer frequency should be, to not strictly alias hardclock() and
statclock() events. Default values are 2 and 4, but could be reduced to 1
if extra interrupts are unwanted.
  kern.eventtimer.idletick - makes each CPU to receive every timer interrupt
independently of whether they busy or not. By default this options is
disabled. If chosen timer is per-CPU and runs in periodic mode, this option
has no effect - all interrupts are generating.

As soon as this patch modifies cpu_idle() on some platforms, I have also
refactored one on x86. Now it makes use of MONITOR/MWAIT instrunctions
(if supported) under high sleep/wakeup rate, as fast alternative to other
methods. It allows SMP scheduler to wake up sleeping CPUs much faster
without using IPI, significantly increasing performance on some highly
task-switching loads.

d3c7b9a08a MFp4 (//depot/projects/mps/...)
Bring in a driver for the LSI Logic MPT2 6Gb SAS controllers.

This driver supports basic I/O, and works with SAS and SATA drives and
expanders.

Basic error recovery works (i.e. timeouts and aborts) as well.

Integrated RAID isn't supported yet, and there are some known bugs.

So this isn't ready for production use, but is certainly ready for
testing and additional development.  For the moment, new commits to this
driver should go into the FreeBSD Perforce repository first
(//depot/projects/mps/...) and then get merged into -current once
they've been vetted.

This has only been added to the amd64 GENERIC, since that is the only
architecture I have tested this driver with.
