778dcb1c13 psm: Support detection of Synaptics touchpad v7.5 and above
Starting with firmware v7.5, the "Read TouchPad Modes" ($01) and "Read
Capabilities" ($02) commands changed: previously constant bytes now
carry variable information.

We now compare those bytes to expected constants only for firmware prior
to v7.5.

The SYSCTL_NODE macro defines a list that stores all child-elements of

Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls

393ec7ad27 Validate INT 15h and 16h vectors more strictly. Traditionally these entry
points are fixed addresses and (U)EFI CSM specification also mandated that.
Unfortunately, (U)EFI CSM specification does not specifically mention this
is to call service routine via interrupt vector table or to jump directly
to the entry point.  As a result, some CSM seems to install two routines
and acts differently, depending on how it was executed, unfortunately.
When INT 15h is used, it calls a function pointer (which is probably a UEFI
service function).  When it jumps directly to the entry point, it executes
a simple and traditional INT 15h service routine.  Therefore, actually there
are two possible fixes, i. e., this fix or jumping directly to the fixed
entry point.  However, we chose this fix because a) keyboard typematic
support via BIOS is becoming extremely rarer and b) we cannot support random
service routine installed by a firmware or a boot loader.  This should fix
Lenovo X220 laptop, specifically.

ce7a3e4774 - If the atkbdc device is assigned an IRQ resource by ACPI or the PnPBIOS,
allow the child atkbd device to reuse that IRQ resource instead of
  reallocating the same IRQ from the parent bus inside the atkbd driver.
- Don't allocate a shared IRQ for the atkbd driver.  For AT keyboard
  devices on an ISA bus the IRQ is not shareable.  Instead, the bus driver
  should mark the IRQ shareable if the bus supports shared IRQs.

ff605594dd On certain chipsets AT keyboard controller isn't present and is
emulated by BIOS using SMI interrupt. On those chipsets reading
from the status port may be thousand times slower than usually.
Sometimes this emilation is not working properly resulting in
commands timing out and since we assume that inb() operation
takes very little time to complete we need to adjust number of
retries to keep waiting time within a designed limits (100ms).
Measure time it takes to make read_status() call and adjust
number of retries accordingly.

To keep it simple, use TSC to measure inb() performance and
keep it to amd64-only, since TSC may not available on older
CPUs.

Also enable detection of the AT controller absence on amd64.

This tunable allows one to enable (1) or disable (0) gestures like tap

By default, the value is -1 in order to keep the current behaviour of
not enabling/disabling gestures explicitly.

3219f535d9 Rewrite x86bios and update its dependent drivers.
- Do not map entire real mode memory (1MB).  Instead, we map IVT/BDA and
ROM area separately.  Most notably, ROM area is mapped as device memory
(uncacheable) as it should be.  User memory is dynamically allocated and
free'ed with contigmalloc(9) and contigfree(9).  Remove now redundant and
potentially dangerous x86bios_alloc.c.  If this emulator ever grows to
support non-PC hardware, we may implement it with rman(9) later.
- Move all host-specific initializations from x86emu_util.c to x86bios.c and
remove now unnecessary x86emu_util.c.  Currently, non-PC hardware is not
supported.  We may use bus_space(9) later when the KPI is fixed.
- Replace all bzero() calls for emulated registers with more obviously named
x86bios_init_regs().  This function also initializes DS and SS properly.
- Add x86bios_get_intr().  This function checks if the interrupt vector is
available for the platform.  It is not necessary for PC-compatible hardware
but it may be needed later. ;-)
- Do not try turning off monitor if DPMS does not support the state.
- Allocate stable memory for VESA OEM strings instead of just holding
pointers to them.  They may or may not be accessible always.  Fix a memory
leak of video mode table while I am here.
- Add (experimental) BIOS POST call for vesa(4).  This function calls VGA
BIOS POST code from the current VGA option ROM.  Some video controllers
cannot save and restore the state properly even if it is claimed to be
supported.  Usually the symptom is blank display after resuming from suspend
state.  If the video mode does not match the previous mode after restoring,
we try BIOS POST and force the known good initial state.  Some magic was
taken from NetBSD (and it was taken from vbetool, I believe.)
- Add a loader tunable for vgapci(4) to give a hint to dpms(4) and vesa(4)
to identify who owns the VESA BIOS.  This is very useful for multi-display
adapter setup.  By default, the POST video controller is automatically
probed and the tunable "hw.pci.default_vgapci_unit" is set to corresponding
vgapci unit number.  You may override it from loader but it is very unlikely
to be necessary.  Unfortunately only AGP/PCI/PCI-E controllers can be
matched because ISA controller does not have necessary device IDs.
- Fix a long standing bug in state save/restore function.  The state buffer
pointer should be ES:BX, not ES:DI according to VBE 3.0.  If it ever worked,
that's because BX was always zero. :-)
- Clean up register initializations more clearer per VBE 3.0.
- Fix a lot of style issues with vesa(4).

ee8cbcb471 - Use x86bios_offset() instead of BIOS_PADDRTOVADDR() macro.[1]
- Clear all registers before calling real mode interrupt handlers as we did
for dpms and vesa and re-enable the function as it should be fixed by this.
- Tidy up register access.  For example, when we call INT 0x15, AH=0xc0,
we used to initialize AX=0xc000 to clear AL at the same time but it is
very confusing.  We don't have to do this any more because we are explicitly
clearing all registers now.
- Check size of system configuration table although it is almost always 8.
This is to make sure we are not reading some random low physical memory.
Hopefully it is just zero in that case. :-)
- Fix some style nits and add more comments.

444b91868b Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.

Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.

For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.

Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.

Bump __FreeBSD_version in order to reflect the newbus lock introduction.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.
