PATA -- pata_amd on 2.6.19 fails to IDENTIFY my DVD-ROM

Good day.

I just tried the PATA driver for my AMD756 chip. During boot, it hangs for 3 minutes failing to identify my DVD-ROM (secondary slave) and does not give me access to it after it timed out.

Situation is AMD756 (a UDMA66 chipset), both channels 80w cables:

1. Primary Master : UDMA133 disk, works fine
2. Primary Slave : Empty
3. Secondary Master : Plextor Premium CD-RW (UDMA33), works fine
4. Secondary Slave : Plextor PX-116A DVD-ROM (UDMA66), does not

All are using cable select and work fine with the old IDE driver and also with an earlier version of the PATA code; I used 2.6.17-rc4-ide1 (which I see is still the latest standalone patch) without problems before.

The 2.6.17-rc4-ide pata_amd version was 0.1.7 and current is 0.2.4. Did try a quick diff between them, but it seems the difference is mostly infrastructural, so the problem is probably further on up.

Excerpt from boot-log (this takes 3 minutes):

By the way -- PATA interfaces (ata1, ata2) start counting at 1 while their devices (.00, .01) start counting at 0 which sort of sucks. While looking at "ata2.01" during boot (with the rest scrolled away) I thought I was looking at secondary master initially. If they can still be named ata0 and ata1, I'd consider that better.

Anyways, as said, all worked fine on 2.6.17-rc4-ide1 including I believe with secondary master tuned to UDMA33 and slave to UDMA66 according to their device capabilities.

Happy to provide more or other information if needed.

Rene.

Please give a shot at v2.6.20-rc2 and report what the kernel says.

Thanks.

This IDENTIFY issue seems already fixed in -rc2. No more pause, and my DVD-ROM works fine again. Unfortunately, another issue seems to have cropped up. On 2.6.20-rc2, hdparm -t /dev/sda gets me ~ 24 M/s while both the old IDE driver and the 2.6.19 PATA driver do ~ 50 M/s

2.6.20-rc2-ata:

# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 72 MB in 3.03 seconds = 23.75 MB/sec

2.6.19-ata:

# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 150 MB in 3.00 seconds = 49.94 MB/sec

Here's the ata part of the 2.6.20-rc2 dmesg:

There's some difference with respect to caching versus 2.6.19 it seems? The same bit for 2.6.19:

Rene.

Great.

Everything seems fine in the dmesg. Performance degradation is probably some other issue in -rc kernel. I'm suspecting recently fixed block layer bug. If it's still the same in the next -rc, please report.

Thanks.

In fact, it's CFQ. The PATA thing was a red herring. 2.6.20-rc2 and 3 give me ~ 24 MB/s from "hdparm t /dev/hda" while 2.6.20-rc1 and below give me ~ 50 MB/s.

Jens: this is due to "[PATCH] cfq-iosched: tighten allow merge criteria", 719d34027e1a186e46a3952e8a24bf91ecc33837:

http://www2.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=719d34027e1a186e46a3952e8a24bf91ecc33837

If I revert that one, I have my 50 M/s back. config and dmesg attached in case they're useful.

[email protected] bounces for me. Could one of the other recipients of parent message try to forward?

Rene.

It should be "Jens Axboe <[email protected]>".

Jens was away over the holidays, hopefully he'll be back today or tomorrow.

Linus

Wow.. same deal here -- sequential throughput drops from 40MB/sec to 28MB/sec with CFQ -- whereas the anticipatory scheduler maintains the 40MB/sec.

Jens.. I wonder if the new merging test is a bit too strict?

There are four possible combinations, and the new code allows merging for two of them: sync+sync and async+async.

But surely one of (not sure which) sync+async or async+sync may also be okay? Or would it?

This is a huge performance hit.

Cheers

Async merge to sync request should be ok. But I wonder what happens with hdparm, since it seems to trigger one of these tests. Very puzzling. I'll dive in and take a look.

Indeed, not acceptable of course. And not intentional :-)

Jens Axboe

The code (written 10 years ago) isn't the best in the world, and will be redone entirely for hdparm-7.0 this year.

But right now, it essentially does this:

loop:

	seek( to sector zero );
	read( 2MBytes );
	repeat loop for 3 seconds

Cheers

OT but care to make -i and -I work equivalently? Such that -i reports more detailed info and user can dump stored id block. Support for IDENTIFY PACKET DEVICE would be nice too.

Thanks.

tejun

hdparm -I works just fine now.

hdparm -i requires the HDIO_GET_IDENTITY ioctl() from drivers/ide, to retrieve the "boot time" copy of the identify block, before any mods are made by the driver. But in recent years, drivers/ide has broken it, in that it tries to maintain the "boot time" copy in sync with the on-drive copy. Kinda makes -i pointless.

Is there a way to retrieve the libata cached copy of the ID block? How?

It already does that, using HDIO_DRIVE_CMD to retrieve it in the same way as for regular IDENTIFY DEVICE commands.

In hdparm-7.0, I'll have it use ATA passthrough when possible for most/all commands.

Cheers

No objection there.

Just implemented and posted patch for HDIO_GET_IDENTITY in an attempt to access ATAPI IDENTIFY block using hdparm.

Hmmm... My hdparm doesn't seem to do that.

# hdparm -V
hdparm v6.9
# hdparm -I /dev/sr0

/dev/sr0:
HDIO_DRIVE_CMD(identify) failed: Input/output error

Am I missing something?

Glad to hear.

Happy new year.

tejun

Sure it does.
Try "strace hdparm -I /dev/sr0" and notice the two ioctl() calls.

The problem is that libata/SCSI always fail it for some reason. Ditto for me right now when I tried it with an SG_IO passthru command.

Contrary to my other posting, I actually *do* have a libata-controlled DVD/RW drive in my box here. So I'll try and see what's happening.

Still digging..

..

Okay, I've dug through the code and found bugs in SCSI and libata. After fixing those, "hdparm -I" now works unmodified for libata ATAPI.

I'll post fixes shortly, after some more testing.

Cheers

Well for pure reading speed, I already use dd_rescue -d /dev/hda /dev/null Gives the same as hdparm -t when acting on uncached data.

Yeah it is, but I don't think it'll fix it (if anything, it'll be more conservative).

Jens Axboe

(to possibly save others from trying -- no, doesn't fix any)

Rene.

As expected. The issue is rq_is_sync(rq) takes the data direction into account as well, while bio_sync() only checks the sync bit. This should fix it.

And here a little more relaxed version, as Mark Lord suggested. We allow merge of async bio into a sync request, but not vice versa.

Both patches pending testing, will do so now.

Performance is right back where it should be now, thanks!

I did have to massage the second patch to get it to apply cleanly after the first patch. You may want to regenerate it against -rc3.

Cheers

Good, thanks!

Hmm odd, I thought I did. Will double check.

Ahh.. I get it now.

I tried to apply the second patch *on top* of the first patch, whereas it was supposed to be a full replacement instead.

Cheers

Ah, then I can see you would have problems :-)
