https://bugs.freedesktop.org/show_bug.cgi?id=35194 Summary: [r600g] Evergreen - failed to map bo Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: rubenf3000@xxxxxxxxx Created an attachment (id=44337) --> (https://bugs.freedesktop.org/attachment.cgi?id=44337) output generated with MESA_GLSL=dump The game "Back to the Future: the game" crashes at many points with the message: radeon_bo_fixed_map failed to map bo EE radeon_bo.c:120 radeon_bo - failed to map bo It usually happens at random moments, altough there are specific actions that trigger the crash reliably. It works correctly using llvmpipe. The "failed to map" message originates in the function "radeon_bo_fixed_map" in "mesa/src/gallium/winsys/r600/drm/radeon_bo.c", when doing a call to mmap; upon debugging, I found it fails with ENOMEM, despite having more than enough free RAM available at the time (it only allocates half a megabyte, and I had almost 1GB of free RAM at the moment of crashing) Upon further inspection, I found that, at the moment of the crash, the game had almost exactly 1 gigabyte of buffer objects mmap'd; could it have something to do with my card having 1GB of video RAM? seems unlikely, since mmap maps to system memory.
