Summary: r600g: GPU hangs and segfaults with piglit
(Regression)
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: monraaf@gmail.com
Created an attachment (id=40180)
--> (https://bugs.freedesktop.org/attachment.cgi?id=40180)
part of backtrace of fbo-blit-d24s8
With latest git master I see a lot of piglit tests segfault and also some more
GPU hangs. e.g. fbo-blit-d24s8 segfaults and fbo-readpixels now hangs the GPU.
git bisect says:
63c3e3a3dc73f8a72e0d08ac4453df57bccdfdb9 is the first bad commit
commit 63c3e3a3dc73f8a72e0d08ac4453df57bccdfdb9

r600: fix my pessimism about PIPE_TRANSFER_x flags
For some reason I though we needed the _DISCARD flag to avoid
readbacks, which isn't true at all. Now write operations should
pipeline properly, gives a good speedup to demos/tunnel.
