b5f4230b55 Retry a bit more agressively on the atapi identify.
Try to support older systems reporting irq0 for the first channels.

Support sharing of the std interrupts (says peter :) )

Dont use READ_CD on normal data reads (2048 bytes), too many old drives
doesn't support this command even if the std says "shall" :(, but still
use READ_CD on all other blocksizes.

Add the geometry to the ad probe, its still usefull.

8ebb100647 General cleanup.
Dont be so verbose in the probe, only ONE line printed now, to get more
info boot verbose. Centralise most printf's in ata-all & ata-dma to use
the ata_printf function, it saves alot of codelines.

Repeat the identify command if drive fails the first.

Protect the timeout functions with splbio.

Dont update the transfer details before we are sure the transfer
succeded, this way they are proberly retried on errors.

Move the handling of next_writeable to userland.

Use the READ_CD command to read CD's. That enables us to read _anything_
via the normal read/write interface. This kindof obsoletes the READAUDIO
ioctl, but we keep that for now.

Prober support for the VIA 82C686, I finally got the right datasheet.

Get rid of atapi_wait, merge it into ata_wait.

Avoid a couple of races by using asleep instead of tsleep.

Always use 16bit transfers on ISA systems.

a237f531ea Yet another cleanup of the VIA code, this time it should work
on all combinations (I hope)...

Add DMA support for the AMD 756 chip (K7 chipset) this is actually the
same as the VIA 82C686 chip (the ATA part that is).

Treat the intel MX chipset PIIX as a PIIX4

Allow UDMA on all disks that say they can handle it.

Cleanup probe printf's a bit

358ef546e6 Have another go at the VIA support, this time use the PCI ID form the

dd933059e1 Add DMA support for the SiS 5591 and old PIIX chipsets.
Add a missing DELAY(1) in ata_wait.

Change the info from ad_version, so the ATA version from the disk can
be used to quantify the DAM modes valid for this drive, ie be more
selective with turning DMA on on older disks that should not support it..

Fix the probe for BIOS enabled DMA in the generic case, master/slave
was reversed in the test.

Check the return for ata_command in all cases, and print warnings if
it fails.

Call ata_dmainit with all dmamodes off when falling back to PIO mode,
that should take care of both the Promise & HPT366 controllers not
being able to handle the fallback...

Cleanup the printf's in the drivers, use the prober device name (if
possible) instead of ataN-master/slave.

3a4f419fb8 Better error handeling:
On UDMA CRC errors retry operation as it might be a fluke, if not fall
back to PIO mode on the failing drive. If you get alot of these your
cabeling is most likely not good enough.

On HARD error using DMA, retry once using PIO, if it succeds using PIO
fall back to PIO mode on the failing drive.

0c7be9be3a Unbreak ATAPI on the Aladdin chipset, only DMA access worked.
Try to use a 32bit mask on the IO addresses, this fixes the alpha
and hopefully doesn't break on any i386 machines.

default, but better be sure..

9282c2bbd5 Fix IRQ allocation bug on controllers using a shared interrupt.
Fix a bug which could cause panics in ad/atapi-interrupt.

Add support for UDMA66 on Promise Ultra/Fasttrak controllers.

Get rid of ATA_IGNORE_INTR, and introduce ATA_WAIT_INTR instead.

Add a delay in the dump routine in ata-disk.c, some controllers
seem to need this. Also dont use the timeout watchdog when dumping.

Disable DMA on ATAPI devices as default, add option ATA_ENABLE_ATAPI_DMA
for those that has HW that works.

Add support for some not-up-to-spec ATAPI devices that returns data
together with completition status on data moving cmd's.

8e3c3eafed useracc() the prequel:
Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>.  This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their
typedefs.

This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.

a84f7947e5 Increase the timeout to be 3*hz. This recalibrates the timeout so that
it has the same value on all platforms.  Previously it was just under
3 seconds on x86 (typically hz<=128) and just under 1/3 of a second on
alpha (typically hz>=1024).  This covers up a race between ad_interrupt()
and ad_timeout() which is being looked into.

69ddfc2954 Add support for the HPT366 chip, this is used on the Abit boards and
their HotRod controller and on SIIG PCI ultra DMA controller. These
changes also made lots of the Promise code go away, its all much more
generic this way.

Get rid of atapi_immed_cmd, instead use the queue to move atapi commands
from interrupt context if nessesary, the entire atapi layer has
gotten an overhaul.

Lots of fixes to utililize the new features in subr_disk.c etc, and
get rid of the last biots of softc arrays in the drivers, the
only one left is atadevices which cannot easily go away (yet).

Use our own malloc names, its a lot easier to track memory usage this way.

General cleanup overall.

f9e0a2c0d2 Be much more selective in claiming devices that might be IDE controllers.
The old algorithm was:

 if class == storage and subclass != SCSI device must be IDE

This results in claiming 'raid' and 'other' storage devices as IDE,
which is typically not the case.
