Summary: X busyloops when huge image in firefox
Product: xorg
Version: git
Platform: x86-64 (AMD64)

Xorg log
When a huge image, e.g. 1500x3000 pixels, is shown in Firefox, any rendering
action related to that image freezes firefox for 5-10 minutes. During that time
X is eating all CPU, spending 30% in user space and 70% in kernel due to
GetTimeInMillis().
Xorg-server xorg-server-1.3.99.0-1538-gefa65a0

DRM kernel modules drm-2.3.0-1229-g43b224f
All of them around 5.5.2008.
nouveau.ko is patched to make AGP init fail, since DFS is broken for me.
To me DRM and Xorg logs show nothing out of the ordinary.

For many times I interrupt X while it is spinning and print the backtrace. There's a disassembly of nouveau_notifier_wait_status. I set breakpoints to NVUploadToScreen and NVDownloadFromScreen to see what kind of calls they get. Looks like it is migrating a big pixmap a lot. w=1703, h=3000 are probably the original dimensions of the image I used to trigger the problem this time. During the dozens of calls to NVUploadToScreen, the firefox window does not show any redrawing. After something like 5 mins running, the window updates instantly, and I can re-trigger the freeze by doing anything that would expose a piece of the huge image. Hmm, I just noticed a pattern there: NVUploadToScreen (pDst=0x2ba0cf4db010, x=0, y=0, w=1703, h=3000 NVUploadToScreen (pDst=0x1314020, x=0, y=0, w=494, h=1315 NVUploadToScreen (pDst=0x2ba0cf4db010, x=0, y=0, w=1703, h=3000 NVUploadToScreen (pDst=0x1314020, x=0, y=0, w=495, h=1315 NVUploadToScreen (pDst=0x2ba0cf4db010, x=0, y=0, w=1703, h=3000 NVUploadToScreen (pDst=0x1314020, x=0, y=0, w=496, h=1315 NVUploadToScreen (pDst=0x2ba0cf4db010, x=0, y=0, w=1703, h=3000 NVUploadToScreen (pDst=0x1314020, x=0, y=0, w=497, h=1315 See the width of the second pixmap. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 9+ messages in thread

Then, adding EXAOptimizeMigration makes the freezing go away, I don't have to wait for it to unfreeze anymore.
