I have a fix buried in http://cgit.freedesktop.org/~ickle/linux-2.6/commit/?h=vmap which I'll tidy up and submit shortly. drm-intel-next-queued just gained a patch that should fix this: commit a14917eeb2cc160d13f4fddefe5f7f9c80953ce1 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Feb 24 21:13:38 2012 +0000 drm/i915: Release the mmap offset when purging a buffer Please verify. Ok, the patch can fix this bug. On ILK(DELL E6510) platform ,running only gem_mmap_offset_exhaustion of the Intel-gpu-tools will fail,it's a regression. the error on the console is like this: mmap failed gem_mmap_offset_exhaustion: gem_mmap_offset_exhaustion.c:67: create_and_map_bo: Assertion `ptr' failed. Aborted (core dumped) the kernel running with is: Kernel: (drm-intel-fixes)44afb3a04391a74309d16180d1e4f8386fdfa745 the GDB backtrace is: #0 0xb7fff424 in __kernel_vsyscall () #1 0x4a16798f in raise () from /lib/libc.so.6 #2 0x4a1692d5 in abort () from /lib/libc.so.6 #3 0x4a1606a5 in __assert_fail_base () from /lib/libc.so.6 #4 0x4a160757 in __assert_fail () from /lib/libc.so.6 #5 0x08048db5 in create_and_map_bo (fd=8) at gem_mmap_offset_exhaustion.c:67 #6 main (argc=1, argv=0xbffff2b4) at gem_mmap_offset_exhaustion.c:91 It is not a regression, it never has been fixed on the -fixes branch as it is targetting -next.
