returns okay when HW probe fails. This happens when comconsole flag is
set but VGA console is used instead.
Back out requested by: bde (He will be looking at other solutions from scratch)
- Define option FORCECONSPEED to force the serial console to
be CONSPEED. I've run into a lot of boards in which
the detect for prior speed doesn't work and ends up with
broken console since it is at the wrong speed.
- If a serial port is marked as a console, but console=vidconsole
and if the serial ports doesn't exist it will be probed and
attached at a 8250 chip. Then writes to that will freeze the
system.
- Add an option flags 0x400000 to mark this as a potential
comconsole in-case the one flaged with 0x10 does not exist
in the system.
This makes it easier to deploy on systems with one or two serial ports.

This is useful in order to get visual indication that something did
not succeed:
# Give it 5 seconds to run
echo 'sjjjjjA.' > /dev/led/error
random_program
echo '0' > /dev/led/error
If random_program takes more than 5 seconds or if it hangs, the LED
will be turned on.
gadgets (hotkeys, lcd, ...) on Asus laptops. I aim to closely track the
acpi4asus project which implements these features in the Linux kernel.
If this breaks your laptop, please let me know how it does it :-)

Logical volumes on these devices show up as LUNs behind another
controller (also known as proxy controller). In order to issue
firmware commands for a volume on a proxy controller, they must be
targeted at the address of the proxy controller it is attached to,
not the Host/PCI controller.
A proxy controller is defined as a device listed in the INQUIRY
PHYSICAL LUNS command who's L2 and L3 SCSI addresses are zero. The
corresponding address returned defines which "bus" the controller
lives on and we use this to create a virtual CAM bus.
A logical volume's addresses first byte defines the logical drive
number. The second byte defines the bus that it is attached to
which corresponds to the BUS of the proxy controller's found or the
Host/PCI controller.
Change event notification to be handled in its own kernel thread.
This is needed since some events may require the driver to sleep
on some operations and this cannot be done during interrupt context.
With this change, it is now possible to create and destroy logical
volumes from FreeBSD, but it requires a native application to
construct the proper firmware commands which is not publicly
available.
Special thanks to John Cagle @ HP for providing remote access to
all the hardware and beating on the storage engineers at HP to
answer my questions.
change the video output but use a separate device with a DSSX method
and a HID of "TOS6201" instead. We use a pseudo-driver to get the handle
for this object and pass it to the acpi_toshiba driver.
This is untested but seems to match the Linux Toshiba driver.
