Output from /sys/kernel/debug/dri/0/radeon_fence_info
--- ring 0 --- Last signaled fence 0x00000000deadbeef Last emitted 0x0000000000000670
--- ring 0 --- Last signaled fence 0x00000000deadbeef Last emitted 0x0000000000000c44
WTF? Well that's a very interesting information you've got us here, thanks allot.
"deadbeef" is a pattern we usually use for ring and IB tests, and I have no idea how that ended up as last signaled fence value.
Could you try Jeromes debugging patch (http://people.freedesktop.org/~glisse/0001-debug-fence-emission-reception.pa...) and attach the resulting output.
Thx, Christian.
