xorg conf (ubuntu stock + UXA) while hung
while hung: cat i915_gem_interrupt Interrupt enable: 00000053 Interrupt identity: 00000000 Interrupt mask: fffedfac Pipe A stat: 00000206 Pipe B stat: 00000000 Interrupts received: 12507 Current sequence: 193290 Waiter sequence: 193293 IRQ sequence: 193289 (also I re-ran it after a few seconds and interrupt count wasnt changing) (while hung) cat gem_objects 4736 objects 771022848 object bytes 6 pinned 17076224 pin bytes 181567488 gtt bytes 234885120 gtt total The bug does not repro if I switch over to EXA using the exact same bits / hardware. I tried to boot the standard jaunty live CD on a laptop with 965 chipset, and then I did "/etc/init.d/gdm stop" on it, changed xorg.conf to UXA and did startx. xorg came up using the live cd bits + UXA and then I opened this JPG and boom xorg frozen on the 965+UXA as well. I had previous done "sudo apt-get install ssh" and "sudo su" followed by "passwd ubuntu" and I had two root shells logged in to the live CD system. The nasty part was that on 965 when the bug triggers all my ssh shells becomes unresponsive as well. All I can tell you is that the fan on the laptop starts to work at 100% speed which is odd because that usually only happens if xorg does into a spin loop and on the G45 what I saw in gdb was not a CPU spin but rather a hang where xorg was stuck in some ioctl. For reasons above I have no idea what the dmesg or xorg_log says on the 965 (I also cant install jaunty on this box because I need to have a stable machine for email etc). Anyway, it's safe to say that 965+UXA seems affected too. Martin, thanks for the bug report. Jian, can you reproduce this? Another ubuntu user has been able to repro this on the following hardware:

I tested it on g45 and gm965, both of them didn't crash. G45 with kernel 2.6.29-rc6 and gm965 with kernel 2.6.29-rc5. G45 runs very fast and seems not affected. GM965 runs a little slow the first time and the icons on desktop and icons in firefox all became blurred. But when I reboot it and run it again it doesn't have such issue. One configuration difference is G45 has 2G memory and gm965 only 1G. Configuration: ------------------------------ Platform: g45 Arch: x86_64 OSD: Fedora release 8 (Werewolf) Kernel: 2.6.29-rc6 Libdrm: (master)1c381092a310af9b1b39b3a983ad5760b71a9025 Mesa: (mesa_7_4_branch)e3050c1777fe4d420bea0171f3624e53513b1055 Xserver: (server-1.6-branch)4557b3f6c4273cd83b701beaf7a150c806fed298 Xf86_video_intel: (master)668b2352a47bcfba75fe0492a5805726222755eb Kernel: (drm-intel-next)126fd9c96d80260a1f2d8dfc72e444e572bcafb7 Platform: gm965 Arch: x86_64 OSD: Fedora release 10 (Cambridge) Kernel: 2.6.29-rc5 Libdrm: (master)1c381092a310af9b1b39b3a983ad5760b71a9025 Mesa: (mesa_7_4_branch)e3050c1777fe4d420bea0171f3624e53513b1055 Xserver: (server-1.6-branch)4557b3f6c4273cd83b701beaf7a150c806fed298 Xf86_video_intel: (master)668b2352a47bcfba75fe0492a5805726222755eb The default config in ubuntu has compiz enabled, so Fedora is a quiet different environment. I think it would be useful if you had at least once machine with ubuntu for testing (maybe you do?). Jaunty just got 2.6.3 uploaded and I ran the repro again. This was the result: At first the image seems to load fine (while it's being downloaded, more and more of it slowly becomes visible). However at some point near the end the image just comes black (see partially_black.png). If I fiddle with the browser window to force a repaint the entire image goes black (see fully_black.png). Also, if I look in dmesg after reproing this bug I see a slew of nasty messages like this: [ 195.560097] [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 195.560102] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 196.112425] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 196.596163] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 197.097209] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 197.655869] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 214.263969] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12 The 2.6.3 version seems to be an improvement in that the xserver no longer crashes, it's just this particular image that is being corrupted. I've now also tested this bug using the ubuntu xorg-edgers PPA repo. Basically, I found that the following versions still show the bug (note I still use the 2.6.28 standard ubuntu kernel): Linux kingfish 2.6.28-11-generic #35-Ubuntu SMP Wed Mar 18 21:55:34 UTC 2009 x86_64 GNU/Linux xserver-xorg-core 2:1.6.0-0ubuntu3 xserver-xorg-core-dbg 2:1.6.0-0ubuntu3 libdrm-intel1 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm-intel1-dbg 2.4.5+git20090314.82eac806-0ubuntu0tormod2 xserver-xorg-video-intel 2:2.6.99.1+git20090319.bedc894a-0ubuntu0tormod xserver-xorg-video-intel-dbg 2:2.6.99.1+git20090319.bedc894a-0ubuntu0tormod libgl1-mesa-dev 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod libgl1-mesa-dri 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod libgl1-mesa-dri-dbg 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod libgl1-mesa-glx 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod libglu1-mesa 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod libglu1-mesa-dev 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod mesa-common-dev 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod mesa-utils 7.3+git20090312+mesa-7-4-branch.a6f7e909-0ubuntu0tormod xlibmesa-gl-dev 1:7.4~5ubuntu16 libdrm-dev 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm-intel1 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm-intel1-dbg 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm-nouveau1 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm2 2.4.5+git20090314.82eac806-0ubuntu0tormod2 libdrm2-dbg 2.4.5+git20090314.82eac806-0ubuntu0tormod2 compiz 1:0.8.2-0ubuntu5 compiz-core 1:0.8.2-0ubuntu5 compiz-dev 1:0.8.2-0ubuntu5 compiz-fusion-plugins-extra 0.8.2-0ubuntu1 compiz-fusion-plugins-main 0.8.2-0ubuntu1 compiz-gnome 1:0.8.2-0ubuntu5 compiz-kde 1:0.8.2-0ubuntu5 compiz-plugins 1:0.8.2-0ubuntu5 compiz-wrapper 1:0.8.2-0ubuntu5 Okay, so now I booted using the same user space components (more or less git HEAD) from the previous comment, but on top of that I used an almost unmodified upstream 2.6.29-rc8 kernel (it was built using the ubuntu kernel config though but no ubuntu sauce patches applied). With this config I saw a black horizontal stripe though the image when it was fully loaded (parts above and below this strip looked fine). When I changed from the singapore containers JPG TAB to another TAB in firefox and then back to the big JPG again, then the JPG looked perfectly. However, I still got some nasty stuff printed to dmesg: [ 253.106340] [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 253.106345] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12 Just those two lines not, nothing else (previous I had many error in dmesg as seen in earlier comments).

all logs (captured after running the repro, using 29rc8+close_to_git_2009mar19 userspace)
With the same 29rc8+recent-user-space config, after I reboot I saw a third error in dmesg (still UXA): [ 120.100180] [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [ 120.100185] [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12 [ 120.110140] [drm:i915_gem_evict_something] *ERROR* inactive empty 1 request empty 1 flushing empty 1 If it doesn't crash right away, also try these things: * single click the big JPG in firefox in order to enlarge it and show it in "100%" natural size... actually what I do normally is that I repeatedly click the image to zoom/dezoom it many many times. * move around the firefox showing the JPG in enlarged mode, I've found that very often other windows in X get corrupted by doing this. It's like if the backing textures for those other windows has been overwritten by garbage and by moving around the firefox window with the big JPG a redraw is forced on the other windows and then the fact that they backing textures contain garbage is revealed. * move around the firefox window while the big image is loading... you will find that the entire machine runs extremely choppy sort of like if kernel space is taking to much time and interferes with "fair scheduling". http://temp.minimum.se/big_jpg_screws_up_other_windows.png screenshot showing what it looks like when the other windows get corrupted. basically the window with the garbage used to be a window showing cgit for mesa and the only thing I did was to view this JPG, click it once and to show it in 100% size and then move around the window with the big JPG. this corruption doesn't happen consistently though, the exact outcome of loading this big JPG seems to be a little bit different every time I try it. We're going to want to make a small testcase for this so we can reliably reproduce it on a variety of configurations without remembering to test it. Some of our paths should handle this correctly. Some of them don't, and it's a bug we're likely to regress on repeatedly.
pseudocode:
for (i = 100; i < 10000; i *= 1.5) {
/* This would get 1.5GB max size. <32 bits, but > aperture size
* because I don't want to think about -ENOMEM or overflow handling
*/
pix = XCreatePixmap(32, i, i);
picture = XRenderCreatePicture(pix);
XFreePixmap(pix);
/* hit a HW accel path */
XRenderFillRectangle(picture, PictOpSrc, &color, 0, 0, i, i);
/* hit a SW path */
XRenderFillRectangle(picture, PictOpConjointOver, &color, 0, 0, i, i);
XFreePicture(picture);

xorg bitmap size stress testing tool
Eric,
I've implemented a tool according to your specifications above, use the attached main.c and compile using "gcc *.c -std=c99 -lXrender -o bitmap_size_stress". The tool has some basic command line options that will allow you to configure max size and whether to hit HW/SW path or both etc. Use "bitmap_size_stress --help" to see a list of parameters. I have licensed it under MIT so I hope intel QA can fork it and build it into some regression test suite.
Good news is that I can hang xorg with it easily on G45. Bad news is that I don't get the exact same stack. I will do more extensive testing later to see if I can repro the exact same stack using some particular set of command line parameters.
The error I get when using this stress testing tool is what looks like a CPU spin inside drm_intel_gem_bo_alloc_internal (I put break points on all functions in stack and ran it for a pretty long time and it didn't hit them):
#0 0x00007f2867bc6887 in drm_intel_gem_bo_alloc_internal (bufmgr=0x1bcd4c0, name=0x7f2867e3e872 "pixmap", size=1140615168,

The original stack I got earlier in this bug report was a "chip hung" stack so X.org wasn't spinning. I get the CPU spin above also using the stress tool with --hw-only parameter.
I experienced the same problem on my i945GM , after working about 2 hours on KDE (Xorg memory useage was ~150mb), I opend the following image with firefox: http://upload.wikimedia.org/wikipedia/commons/5/5a/Ikea_Dortmund_Ellinghausen.JPG This was intel-2.6.99.902 and kernel-2.6.29rc8: and git endless messages like: [drm:i915_gem_execbuffer] *ERROR* Failed to pin buffers -12 [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty [drm:i915_gem_object_pin] *ERROR* Failure to bind: -12 [drm:i915_gem_evict_something] *ERROR* inactive empty 1 request empty 1 flushing empty 1 [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty Created attachment 24571 [details]
gdb trace when UXA goes into CPU spin while repro'ing this bug using mesa git HEAD april 4th
I tried this repro again today with 2.4.6ish libdrm, 2:2.6.99ish intel ddx, .29 kernel and mesa git HEAD as of april 4th.
This I did not run into a "chip hung" ioctl() block thing, instead the xserver went into CPU spin entirely inside pixmanBltsse2() in the top stack frame below:
#0 pixmanBltsse2 (src_bits=<value optimized out>, dst_bits=0x7f20a678c000, src_stride=40448, dst_stride=40448, src_bpp=<value optimized out>,

Okay so now I did this in gdb:
(gdb) break pixmanBltsse2
(gdb) commands
>print height
>c
>end
(gdb) c
And thus gdb printed all parameters passed to this function every time it was called. Then I ran the repro and I _think_ these were the ones passed into the function when it never returned (the width clearly indicates it has something to do with the big jpg file).

If the buffer is too large or not suitable for a GPU operation, we currently fallback and perform the composite on the CPU.

The effect is particularly noticeable on pathological websites that use very large background images.

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Step 2 is a kernel patch to avoid the pathological eviction behaviour. Created attachment 35510 [details] [review] Protect mmapped buffers from causal eviction. Dropping priority, this now depends upon a kernel patch to protect against any remaining pathological cases. However, the DDX should prevent the hang from occurring again without the kernel patch. *** Bug 28005 has been marked as a duplicate of this bug. *** Woohoo! commit e2bf07fe23fd11a2acba609bf34ccc59c5553389 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Aug 7 11:01:24 2010 +0100 drm/i915: Implement fair lru eviction across both rings. (v2) Based in a large part upon Daniel Vetter's implementation and adapted for handling multiple rings in a single pass. This should lead to better gtt usage and fixes the page-fault-of-doom triggered. The fairness is provided by scanning through the GTT space amalgamating space in rendering order. As soon as we have a contiguous space in the GTT large enough for the new object (and its alignment), evict any object which lies within that space. This should keep more objects resident in the GTT. Doing throughput testing on a PineView machine with cairo-perf-trace indicates that there is very little difference with the new LRU scan, perhaps a small improvement... Except oddly for the poppler trace.
