The atapi subsystem has gotten better error handeling and timeouts,
it also tries a REQUEST SENSE command when devices returns errors,
to give a little more info as to what went wrong. It might be a
little verbose for now, but I'm interested in as much feedback on
errors as possible, especially timeouts, as I'm a bit in doubt if
I've chosen resonable default values everywhere.
The disk driver has been changed a bit to prepare for tagged queing,
which is next on my list.
The disk driver has grown a dump routine, I got one implementation
from Darrell Anderson <anderson@cs.duke.edu> which also did
partial dumps (usefull on big memory machines) I left out the
partial stuff for now, and changed the rest alot to fit into the new
ad_request framework.
Some minor cleanups and rearrangements as well.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, again you have been warned :)
Notebook owners should be carefull that their machines dont suspend
as this might cause trouble...
But please tell me how it works for you!
Enjoy!

and insertion should affect the line the cursor is on only.
This change should have been committed together with syscons.c rev 1.308.
(I forgot to do so, when I committed syscons.c :-(

If the drive goes down, queue a close to the daemon. In many cases
this function gets called in process context, so it could do it
directly, but it's more trouble finding out where we came from than
getting the daemon to do it.
Don't bzero the buffer structure, it's been done already by
allocrqg.
sdio:
Build up a correct buffer header, don't steal linkages from system
buffer headers.

1. Rise is recognized in identdcpu.c.
2. The TSC is not written to. A workaround for the CPU bug is being
applied to clock.c (the bug being that the mP6 has TSC enabled
in its CPUID-capabilities, but it only supports reading it. If we
try to write to it (MSR 16), a GPF occurs.) The new behavior is that
FreeBSD will _not_ zero the TSC. Instead, we do a bit of 64-bit
arithmetic.

wfd driver code tries to give wd driver first crack at ioctl's,
but incorrectly interprets internal error and never gets to send
eject to ATAPI device.
(this is fixed in the atapi-fd driver)

* Conformance with Dingo specification. This includes:
Collision/error statistics gathering.
Multicast address filtering, eg. the hash filter.
Initialisation and interrupt handling sequences.
Note that I've started on some of this already in v1.20.
* The probe routine needs some more work, to identify oddities such as the
REM10.
* There are still problems with the autonegotiation code; specifically, it
won't autonegotiate with some 10/100 hubs. This might simply be the hardware
not getting along, in which case there's nothing we can do, but it's still
worth investigating
* CEM28/CEM33 support. Should be able to integrate this directly from the
Linux code.
* Performance enhancements:
Full-duplex on 10Mbit networks.
Virtual shared-memory mode.
Early send and receive modes.

- Split syscons source code into manageable chunks and reorganize
some of complicated functions.
- Many static variables are moved to the softc structure.
- Added a new key function, PREV. When this key is pressed, the vty
immediately before the current vty will become foreground. Analogue
to PREV, which is usually assigned to the PrntScrn key.

- Modified the kernel console input function sccngetc() so that it
handles function keys properly.
- Reorganized the screen update routine.
- VT switching code is reorganized. It now should be slightly more
robust than before.
- Added the DEVICE_RESUME function so that syscons no longer hooks the
APM resume event directly.
- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
SC_NO_HISTORY and SC_NO_SYSMOUSE.
Various parts of syscons can be omitted so that the kernel size is
reduced.
SC_PIXEL_MODE
Made the VESA 800x600 mode an option, rather than a standard part of
syscons.
SC_DISABLE_DDBKEY
Disables the `debug' key combination.
SC_ALT_MOUSE_IMAGE
Inverse the character cell at the mouse cursor position in the text
console, rather than drawing an arrow on the screen.

SC_DFLT_FONT
makeoptions "SC_DFLT_FONT=_font_name_"
Include the named font as the default font of syscons. 16-line,
14-line and 8-line font data will be compiled in. This option replaces
the existing STD8X16FONT option, which loads 16-line font data only.
- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.
- The video driver provides a set of ioctl commands to manipulate the
frame buffer.
- New kernel configuration option: VGA_WIDTH90
Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These
modes are mot always supported by the video card.

- The header file machine/console.h is reorganized; its contents is now
split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
(another new file). machine/console.h is still maintained for
compatibility reasons.
- Kernel console selection/installation routines are fixed and
slightly rebumped so that it should now be possible to switch between
the interanl kernel console (sc or vt) and a remote kernel console
(sio) again, as it was in 2.x, 3.0 and 3.1.
- Screen savers and splash screen decoders
Because of the header file reorganization described above, screen
savers and splash screen decoders are slightly modified. After this
update, /sys/modules/syscons/saver.h is no longer necessary and is
removed.
