There is still some doubt over eDP, with 011b9910bdaf failing for Jim Gettys but seeming required for other (currently working in .37) machines. And despite Linus's intervention, backlight controls are still broken for some users. I've taken the conservative approach and disabled GPU semaphores by default since that prevents one cause of hangs, even though I think it is fixed by the earlier patch to prevent the FIFO overflow. The other patch addresses a bug introduced by the combination of relaxed fencing and fence pipelining infrastructure where to forgot to teardown a bound buffer if it invalidated its new alignment constraints. Hopefully this will fix the reported corruption for gen2/3 devices, though there is the possibility of further underlying bugs. -Chris The following changes since commit fb62c00a6d8942775abc23d1621db1252e2d93d1: Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client (2011-03-05 10:43:22 -0800) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git drm-intel-fixes Chris Wilson (4): Revert "drm/i915: fix corruptions on i8xx due to relaxed fencing" drm/i915: Do not overflow the MMADDR write FIFO drm/i915: Disable GPU semaphores by default drm/i915: Rebind the buffer if its alignment constraints changes with tiling drivers/gpu/drm/i915/i915_debugfs.c | 4 +- drivers/gpu/drm/i915/i915_drv.c | 17 +++++++++++- drivers/gpu/drm/i915/i915_drv.h | 24 ++++++++++++++---- drivers/gpu/drm/i915/i915_gem.c | 2 +- drivers/gpu/drm/i915/i915_gem_execbuffer.c | 4 +- drivers/gpu/drm/i915/i915_gem_tiling.c | 37 +++++++++++++-------------- drivers/gpu/drm/i915/i915_reg.h | 2 + drivers/gpu/drm/i915/intel_display.c | 8 +++--- drivers/gpu/drm/i915/intel_ringbuffer.h | 13 +++++---- 9 files changed, 70 insertions(+), 41 deletions(-) -- Chris Wilson, Intel Open Source Technology Centre
