I've posted a new patch versus 2.6.17-rc3 up at the usual location.
http://zeniv.linux.org.uk/~alan/IDE
This has a lot less in it that touches the core libata code as the
majority of the changes for the core are now merged. I'm still working
down various bug reports and there are bigger changes to do with simplex
that are known but not yet resolved.
There are a couple of things still not yet dealt with in the core,
notably some of the speed management and serialization code but most of
it is there.
Driver support is now more extensive than the old drivers/ide code
although the degree of testing is much lower and there will be plenty of
small bugs left to knock out of the tuning code.
Bug reports/patches/comments welcome

Aren't there a bug in via cable detect ?
The via ide driver do
pci_read_config_dword(dev, VIA_UDMA_TIMING, &u);
for (i = 24; i >= 0; i -= 8)
if (((u >> i) & 0x10) ||
(((u >> i) & 0x20) &&
(((u >> i) & 7) < 6))) {
/* BIOS 80-wire bit or
* UDMA w/ < 60ns/cycle
*/
vdev->via_80w |= (1 << (1 - (i >> 4)));
}
80w = (vdev->via_80w >> hwif->channel) & 1;
upper bit are for channel 0 and lower bit for channel 1.
the pata driver do
pci_read_config_dword(pdev, 0x50, &ata66);
80w = ata66 & (0x1010 << (16 * ap->hard_port_no))
upper bit are for channel 1 and lower bit for channel 0.
at boot VIA_UDMA_TIMING is 0xf1f1e6e6 for a 80w cable on channel 0 and 40w
cable on channel 1.
Pata driver set my UDMA100 disk at UDMA33.
Matthieu.
PS : any idea in order to allow to work my cdrw drive, that don't return
interrupt when setting xfermode ?

Am currently running with this on AMD756. Both channels have 80w cables.

It seems to be working nicely. The hdparm -t result is slightly lower
than with the old IDE driver. With the default settings, the old IDE
driver gives me 49.4/5 MB/s, and 50.6/7 after a hdparm -a 1024. With
default setting the new driver gives me 46.6/7 MB/s, and 48.8/9 after
that same hdparm -a 1024. Higher than -a 1024 does not seem to matter
with either driver. The numbers are close, but completely repeatable.
CD and DVD ROMs are also working fine, including readcd and CDDA. This
is what cdparanoia has to say about sr0:
===
Checking /dev/sr0 for cdrom...
Testing /dev/sr0 for cooked ioctl() interface
/dev/sr0 is not a cooked ioctl CDROM.
Testing /dev/sr0 for SCSI interface
generic device: /dev/sg1
ioctl device: /dev/sr0
Found an accessible SCSI CDROM drive.
Looking at revision of the SG interface in use...
SG interface version 3.5.33; OK.
CDROM model sensed sensed: PLEXTOR CD-R PREMIUM 1.06
Checking for SCSI emulation...
Drive is ATAPI (using SCSI host adaptor emulation)
Couldn't disable kernel command translation layer
Checking for MMC style command set...
Drive is MMC style
DMA scatter/gather table entries: 127
table entry size: 32768 bytes
maximum theoretical transfer: 1769 sectors
Setting default read size to 13 sectors (30576 bytes).
Verifying CDDA command set...
Expected command set reads OK.
===
The "couldn't disable kernel command translation layer" bit is probably
expected?
It does have somwhat higher system times during ripping. The old IDE
driver, with cdparanoia -v -z -B, gives me some 30% user and 10-15%
system. This driver gets me 15-25% user and 15-20 % system. Lower user
times though, so I guess that might just be a protocol difference?
In any case, it seems that this driver is also not using DMA for CDDA? I
am using slackware 10.2 (vanilla) "cdparanoia III release 9.8 (March 23,
2001)". A while ago someone on this list pointed to some patches for
SG_IO use with cdparanoia but this made my machine highly unstable.
Would you like me to retest with this new driver? If so, any specific
version of cdparanoia?
DVD is fine. UDMA33 though, although the drive is capable of UDMA66:
===
ata2: PATA max UDMA/66 cmd 0x170 ctl 0x376 bmdma 0xF008 irq 15

ata2: dev 1 ATAPI, max UDMA/66
ata2: dev 0 configured for UDMA/33
ata2: dev 1 configured for UDMA/33
===
The old IDE driver does set it to UDMA66 after an ide1=ata66, and after
the recently merged patch to amd74xx to "only do disk side cable
detection". I assumed it was that same problem, but I see that
amd_early_probe_init() also assumes 80w cables on amd756 same as amd74xx
does. Do I need to tell it something additionally to make it do UDMA66?
This is what the drive itself says, through the old IDE driver:
===

Hope this was a useful report...

Different oops I think 8) I've fixed that one now although it may well
be that ide2 once I release it now oopses where it did before the PCMCIA
change rather than where it did this time.

I think so yes.

It should use whatever the sr.c SCSI CD driver code uses when doing
CDDA, and it isn't directly a part of the driver (although there are
hooks so drivers can filter/control what ATAPI can be done with DMA).

I would be interested to know what happens if you try this, version
doesn't matter.
> DVD is fine. UDMA33 though, although the drive is capable of UDMA66:
The core code sets both drives to the same speed on the cable. The old
-ac code fixed this but I've not pushed that change over (in part
because it will naturally happen now as other changes go in).
Thus dev1 is pulling dev0 down to UDMA33 for now.

That change is in the libata driver as well so should not be a problem.

Ahh, yes.. no longer through alloc_io_space. And the setup_irq
message/trace is new. ;)
Is there anything I can do to help debug this?

Did so. Took vanilla cdparanoia-III-alpha9.8 from:
http://downloads.xiph.org/releases/cdparanoia/cdparanoia-III-alpha9.8.src.tgz
and then applied the labels and sgio patches from:
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/4/en/os/i386/SRPMS/cdparanoia-alpha9.8-24.src.rpm
Unfortunately, the only difference with regular cdparanoia seems to be
that info bit. Now it's just:
===
Checking /dev/cdrom for cdrom...
CDROM model sensed sensed: PLEXTOR CD-R PREMIUM 1.06
Checking for SCSI emulation...
Drive is ATAPI (using SCSI host adaptor emulation)
Checking for MMC style command set...
Drive is MMC style
Verifying CDDA command set...
Expected command set reads OK.
===
Nothing about the SG interface and no "Couldn't disable kernel command
translation layer" bit therefore. It gives me the exact same times
regular cdparanoia does; 15-25% user, 15-20% system. This might be
expected; it seems not unlikely in fact that the SG_IO patch would only
be expected to do something for usage through the IDE driver. Added Jens
Axboe to the CC...
I rechecked that it does indeed make a difference for the IDE driver and
it does. Almost immediate timeout/lockups again, as I reported once before:
http://lkml.org/lkml/2006/1/10/373
This does seem to be drive dependent -- I do not get this when ripping
from my DVD-ROM drive (hdd, sr1). There is also no difference in times
though between normal and patched cdparanoia on hdd, so as a summary of
what this SG_IO patch is doing for me, "nothing useful" will do nicely.
Oh well; in any case, in the context of this pata test, no regressions!
Rene.

Well, other than spamming the kernel message buffer into oblivion. Must
have missed these last time around but cdparanoia (regular cdparanoia)
triggers tons and tons of these, with both sr0 (hdc, a CD-RW) and sr1
(hdd, DVD-ROM):

Confirmed. Realised I was on 2.6.17-rc4-ide1 now, and 2.6.17-rc3-ide1 last

2.6.17-rc3-ide1.
