b5037ea036 Add support for APIC_IO to pci IRQ configuration.
The support for APIC_IO was lost in the new set of pci modules.  This patch
restores the ability to build SMP/APIC_IO kernels.

cfea775806 Completely replace the PCI bus driver code to make it better reflect
reality. There will be a new call interface, but for now the file
pci_compat.c (which is to be deleted, after all drivers are converted)
provides an emulation of the old PCI bus driver functions. The only
change that might be visible to drivers is, that the type pcici_t
(which had been meant to be just a handle, whose exact definition
should not be relied on), has been converted into a pcicfgregs* .

The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t
and has been converted to just call the PCI drivers functions to access
configuration space register, instead of inventing its own ...

This code is by no means complete, but assumed to be fully operational,
and brings the official code base more in line with my development code.

A new generic device descriptor data type has to be agreed on. The PCI
code will then use that data type to provide new functionality:

1) userconfig support
2) "wired" PCI devices
3) conflicts checking against ISA/EISA
4) maps will depend on the command register enable bits
5) PCI to Anything bridges can be defined as devices,
   and are probed like any "standard" PCI device.

The following features are currently missing, but will be added back,
soon:

1) unknown device probe message
2) suppression of "mirrored" devices caused by ancient, broken chip-sets

This code relies on generic shared interrupt support just commited to
kern_intr.c (plus the modifications of isa.c and isa_device.h).

f81fb1863d Several bug fixes for the ee16 support from Richard Straka:
1) Adjust NFRAMES from 16 to 8 per 16k of memory.
2) Acknowledge interrupts to the card early in the interrupt
   handler before processing the event that caused the interrupt.
   This frees the card to process addtional events instead of
   waiting for the driver to finish handling events.
3) Changed the initialization of the transmit buffers to be a
   loop so that the number of buffers can be more easily changed.
4) Moved the code to take the adapter out of loop back mode to just
   before we enable the receiver.

I also made the driver dynamically size its resource arrays at attach
time so that we can take full advantage of adapters with more than 16k
of memory.

Richard has some other changes he's working on to improve performance,
but this should get ee16 support working reliably again.

Thanks to Wes Santee <wes@bogon.net> for testing these patches.

27ddec53f7 Major overhaul of the SyncPPP layer. Basically, this comprises now a
full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

3347d1b140 1) font loading (two fixes)
When an ioctl command SW_XXXX is issued, scioctl() checks if the font
appropriate for the specified mode is already loaded.  The check was
correctly done for 8 line and 16 line fonts, but not for 14 line font.

The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but
were sometimes treated as bit flags. They are now defined as bit
flags.

2) screen blinking (two fixes)

Removed a redundant call to timeout() in do_bell().

Don't let blink_screen() write to the video buffer if the screen is in
the graphics (UNKNOWN) mode.

3) screen saver timeout

The ioctl command CONS_BLANKTIME sets the screen saver's timeout.  The
value of zero will disable the screen saver. If the screen saver is
currently running it should be stopped.

4) border color and destructive cursor (two fixes)

The border color and the cursor type can be changed via escape
sequences.  But only VGA can change the border color and set the
cursor type to destructive (CHAR_CURSOR) in the current syscons.
scan_esc() failed to check this.

8cea5b917d This mega-commit brings the following:
. It makes cd9660 root f/s working again.
. It makes CD9660 a new-style option.
. It adds support to mount an ISO9660 multi-session CD-ROM as the root
  filesystem (the last session actually, but that's what is expected
  behaviour).

Sigh.  The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work.  Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-(  I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.

While doing this, i noticed the following bogosities in existing CD-ROM
drivers:

wcd:	This driver is likely to be totally bogus when someone tries
	two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
	commands with requesting MSF format, since it apparently
	operates on an internal table.

scd:	This driver apparently returns just a single TOC entry only for
	the CDIOREADTOCENTRYS command.

I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver.  I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver.  When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.

a04669c796 Addresses the following two problems.
1) i586_bcopy() problem

There have been a number of reports that the syscons doesn't work
properly if i586_bcopy() is enabled.

The problem prevented users from installing 2.2(.1)-RELEASE.  The
symptom is that the system looks frozen during device probe or just
before the main installation menu.  The workaround was to specify the
flag 0x01 to the npx device so that i586_bcopy() is disabled.

The patch forces the syscons to call generic_bcopy() when copying
to/from the video memory, even if CPU is Pentium and i586_bcopy() is
enabled. i586_bcopy() is still called for copy operations between
non-video memory regions.

PR: kern/2277, kern/3066, kern/3107, kern/3134

2) video mode parameter table problem

The syscons reads and uses the video mode parameter table provided by
the VGA BIOS to set VGA registers when changing video mode and
modifying font data. It appears that in some VGA BIOSes the table is
not ordered as the syscons expects, and this leads to screen
corruption.

The problem prevented users from installing 2.2(.1)-RELEASE. The
symptom is the corrupt screen or strange vertical lines soon after the
kernel is loaded into memory (just after the kernel decompression).

The patch performs simplistic test and if it fails, set video_mode_ptr
to NULL so that the video mode switching won't happen.

This is an interim kludge. There should be a better way to deal with
the problem.

The kernel should run pretty much "as before" without the options to

have been put off since the SMP kernel is in a moderately good condition
at the moment.

3ca5733308 The following scenario would result in a bogus residual being reported
if SCB Paging was enabled:

    disconnect with more data to transfer
    disconnected SCB gets paged out
    target reconnects so we page SCB back in
    target completes transfer so residual is 0
    target disconnects
    SCB gets reused but not paged out since the residual is 0 (optimization)
    target reconnects so we page the SCB back in
    we report a residual because of stale residual information.

The fix for this is to set a flag that forces the SCB to be paged back
up to the host if we page in an SCB with a residual

used a general purpose function taking 2 args for the timeout

Add a missing call to "add_scb_to_free_list" in the non paging case.  In
the non-paging case, the SCBs don't really need to be on the free list,
