Subject: [Bug 16911] New: xserver EXA optimization causes nv31 to crash
Date: Wed, 30 Jul 2008 16:03:46 -0700 (PDT) [thread overview]
Message-ID: <bug-16911-8800@http.bugs.freedesktop.org/> (raw)
http://bugs.freedesktop.org/show_bug.cgi?id=16911
Summary: xserver EXA optimization causes nv31 to crash
Product: xorg
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

Kernel log
Following the commit of a3afa6f2fb80489f7b6a88d12def09281d32ed94 "EXA: Optimize
GXcopy tiled fills." to the xserver, the nouveau driver (git HEAD of both ddx
and drm) will crash on certain webpages, with
[drm] PGRAPH_ERROR - nSource: LIMIT_COLOR, nStatus: PROTECTION_FAULT
[drm] PGRAPH_ERROR - Ch 1/6 Class 0x009f Mthd 0x0308 Data 0x00000003:0x00f304f8
in the kernel log and a fifo lockup in the ddx log -- both attached. A simple
reproducible case is using Firefox (2.0.0.16) on
http://people.freedesktop.org/~stuart/pgraph_limit_color/crash.html
Going back to the previous xserver commit "EXA: Replace open coded CopyArea
logic with GC op call.", the page does not cause the driver error, nor a crash.
black.png used in the page was simply created in the GIMP using a new image and
a bucket fill. I suspect the size of the background image is a factor, as tests
using a 200x200 PNG did not crash.
