gdb trace show xorg CPU spin caused by visiting website mundoplus.tv

If I turn off compiz and open that URL in firefox xorg still locks up but instead of being stuck permanently blocking in drmIoctl() it goes into a CPU spin.

At this time the backtrace is essentially:

#1  0xb7d35ea9 in ioctl () from /lib/tls/i686/cmov/libc.so.6
#2  0xb7b30a6d in drmDMA () from /usr/lib/libdrm.so.2

If I put breakpoints on the three top most stack frames I see ioctl() and drmDMA() being hit constantly but the breakpoint on RADEONCPGetBuffer() is never hit so I don't think that function ever exits.

Breakpoint 1, 0xb7d35e90 in ioctl () from /lib/tls/i686/cmov/libc.so.6
Continuing.
Breakpoint 2, 0xb7b309f5 in drmDMA () from /usr/lib/libdrm.so.2

etc etc

I'm attaching a full gdb showing this trace.

We're getting _a lot_ of duplicate bug reports (and confirms) for this bug in the downstream bug tracker. Around 10 bug reports each containing 1-4 users confirming the problem.

Comment 3 Michel Dänzer 2009-05-11 07:34:34 UTC
Does

    Option "RenderAccel" "off"

or

    Option "DRI" "off"

or any other usual suspect work around the problem?
Comment 4 martin 2009-05-11 08:04:42 UTC
With DRI off the bug does not repro any more. If I remove DRI "off" and use RenderAccel "off" instead then bug comes back.
Comment 5 martin 2009-05-11 11:07:48 UTC
Option "AccelMethod" "XAA" also makes the bug go away (I guess it's just hitting a different execution path).

As I mentioned earlier, if you have compiz ON this turns into a ioctl() that blocks indefinitely with 0% CPU activity in xorg. If you have compiz OFF it instead turns info a CPU spin inside Xorg hitting the breakpoints in the order I explained in comment #1.

This latter fact means that on modern dual core machines people basically see "50% CPU in use by Xorg" while their system is still sluggish but it can be operated still. Whereas quad core users see "xorg hogs 25% CPU constantly". By looking more carefully into the downstream bug reports I think I have another 10 duplicates of this bug, it's just that quad core users tend to report "a performance problem" rather than a freeze/lockup so I didn't realized that these bugs where proabably duplicates at first.

There is still one thing that makes me not want to dup all those bugs against my bug though, and that is the fact that some of these "25% CPU in xorg" bugs show a spinning stacktrace rooted in exaGlyphs() where as I explained above that the CPU spin that I see for _this_ bug is rooted in RADEONPrepareSolidCP(). However, both of these stacks have drmIoctl() and ioctl() and their two topmost stack frames.

FWIW, an example of this (a CPU spinning xorg stack rooted in exaGlyphs function) in the downstream tracker is bug 347078:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/347078

So, I even believe that upstream FDO bug 21683 is a potential duplicate of this bug:

all defaults except EXANoComposite==true.... still freezes

Let me know if there is anything else that can help narrow it down.
Comment 7 martin 2009-05-11 17:37:59 UTC
I've downloaded all the files on that website using "wget -m" and then I opened them one by one in Firefox. The offending item is a bitmap with 8K pixels height:
http://mundoplus.tv/tpl/v3/panBR.png

I put a copy here in case they change their website:
http://pages.minimum.se/crashers/ddx_stressers/panBR.png

An interesting detail is that the following 10K pixels wide bitmap opens just fine on the same machine:
http://pages.minimum.se/crashers/ddx_stressers/Singapore_port_panorama.jpg
(this latter 10K wide bitmap actually crashes the intel DDX driver when running in UXA mode but that's another story)

Hold your horses... that only talks about slowdowns, not a lockup.

Backtraces are generally not useful for diagnosing GPU lockups because they will just more or less randomly show one of the places where the drivers wait for the GPU to catch up (which never happens because it's locked up). Instead one has to focus on what triggers the lockup.

<snip>

Yes, it does. With these extra coordinate checks the crash no longer occours here. Tested both the website and the individual PNG image in Firefox. I have an ATI X1400 Radeon Mobility [1002:7145] w/128 MB RAM. Patch applied to master radeon branch as of today.

For the hell of it, I also tested with a 10x6000 PNG image in Firefox (which should be *within* the limits introduced by this patch, no?), and that works as well, no crash .. Also, no crash for a 10x7000 PNG image.

This problem also affects ATI Radeon Mobility X1600/M56P [1002:71c5] with 256MB RAM.

So far, so good. Can you set a gdb breakpoint on the RADEONUploadToScreenCP() line that returns FALSE after these new checks, and attach a backtrace from when it triggers?

Also tested without the "..(x + w) > 8191" criterion (that is only y+height check), and still no crash. Tested website, plus a 12000x10 png and a 10x12000 png (both PNGs have transparency). And also tested with a 9000x9000 PNG (also w/transparency). I'll see if can get you the debugging-info you have requested ..

I succeeded in attaching gdb to the Xorg process and setting the required breakpoint. I did this from a VT. Then I told gdb to continue execution (with c command), but when switching back to Xorg all I get is a black screen (had to reboot).

Perhaps this will do it for me:
handle SIGUSR1 nostop

Apparently gdb halts things on VT switch. I don't have the possibility of logging in via ssh where I'm currently at.

Oh, and I compiled the radeon-driver with no gcc optimization (-O0).

Comment 18 Øyvind Stegard 2009-05-12 09:36:48 UTC
I did some more testing with sizes because of the of number 8192 (=2^13), which is the height of the image that triggers this.

Here are the results:

16x8191 PNG image: No crash. [http://folk.uio.no/oyvinst/fdsbug21598/16x8191.png]
16x8192 PNG image: FREEZE    [http://folk.uio.no/oyvinst/fdsbug21598/16x8192.png]
16x8193 PNG image: No crash. [http://folk.uio.no/oyvinst/fdsbug21598/16x8193.png]

It looks like this bug has something to do with height being exactly 8192.

I created various PNG test-images of different dimensions, they can be found here:
http://folk.uio.no/oyvinst/fdsbug21598/

Of all these images, *only* the 16x8192 image triggers the crash/freeze. All images created in Gimp with transparency (don't know if that's really necessary..).

Hope this might help somewhat in tracking this down.
Comment 19 martin 2009-05-12 10:58:36 UTC
I modified my -ati driver according to the patch in comment #9 and then I put a
breakpoint on the "return FALSE" just below it. This coordinate hack patch
indeed makes the bug go away! And when I surf to mundoplus.tv I do hit the
proposed breakpoint and here is the "bt full" from that breakpoint. I compiled
with DEB_BUILD_OPTIONS="noopt nostrip" which I think means essentially "-O0
-g3" or something like that.

I can confirm that 16x8191.png and 16x8193.png load just fine on unpatched jaunty versions whereas 16x8192.png triggers the bug.

I also grepped in the -ati driver for the number 8192 and that turns up several very interesting source lines that uses this number as maximum texture sizes and vport_scissor for example.

Maybe the "viewport cropping" has a off by one error?

With <width>x8193, does the breakpoint get hit?

What about 8191x<height> vs. 8192x<height> vs. 8193x<height>?

P.S. Please try to keep comments tidy to avoid cluttering up reports.

Using the -ati driver modified with the coord paranoia patch as per comment #9:
For 16x8192 the breakpoint gets hit.
For 16x8191 and 16x8193 the breakpoint does not get hit.

Using the same patched -ati driver and breakpoint set I also tried (after rotating oyvind's PNGs in GIMP, i'm unsure about what this transformation did to transparency if that matters):
8191x16 (no crash, no breakpoint hit)
8192x16 (no crash, no breakpoint hit)
8193x16 (no crash, no breakpoint hit)

I also reverted to the unpatched jaunty driver and just as I suspected 8191x16, 8192x16 and 8193x16 loads just fine there as well. If needed, you can find my rotated PNGs here:

EXA coordinate limit fixups

This is probably the real fix. Not sure about the R600 changes, but they make everything consistent with the stricter checks in R600CheckComposite().

I don't think the transparency matters, but I realized in the meantime that it hits the pitch limit at much lower width.

I can confirm that the patch from comment #24 makes it possible to open all PNGs mentioned in this bug report and no lockups or issues was seen (nothing barfed in xorg.log or dmesg).

Is this suitable for cherry picking onto the 6.12.2 we currently have in Ubuntu? The patch clearly applies cleanly and works nicely from what I can tell with my limited testing so far at least.

Thanks a ton MrCooper.

Fix pushed to the Git master and 6.12 branches, thanks for all the testing.

I haven't pushed the R600 changes as they don't seem to be necessary. Maybe the stricter check in R600CheckComposite() should be relaxed instead.

Hello,

I'm still having the firefox-lockup with the mentionned png-image and my xorg was apparently released in August. Maybe this is normal, my not, but I just wanted to share it.

My xorg-info:

My ati-module-version:

II) Module ati: vendor="X.Org Foundation"
        compiled for 1.6.1, module version = 6.12.2
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 5.0

It seems to be 6.12 like mentionned above.

Kind regards,

Michel

The fix is only in 6.12.3.
