[Mesa-dev] [PATCH] winsys/radeon: add command stream replay dump for faulty lockup v2
j.glisse at gmail.com
j.glisse at gmail.com
Wed Mar 27 09:01:26 PDT 2013
From: Jerome Glisse <jglisse at redhat.com>
Build time option, set RADEON_CS_DUMP_ON_LOCKUP to 1 in radeon_drm_cs.h to
enable it.
When enabled after each cs submission the code will try to detect lockup by
waiting on one of the buffer of the cs to become idle, after a timeout it
will consider that the cs triggered a lockup and will write a radeon_lockup.c
file in current directory that have all information for replaying the cs.
To build this file :
gcc -O0 -g radeon_lockup.c -ldrm -o radeon_lockup -I/usr/include/libdrm
v2: Add radeon_ctx.h file to mesa git tree
