INTEL_DEBUG=cs shared atomic add
All 48 dEQP tests matching '*shared_var*atomic*' currently fail (with kernel
4.4.1, mesa git + Ken's compute state fixing series). This is how I run it:
MESA_GLES_VERSION_OVERRIDE=3.1 LD_LIBRARY_PATH=/home/ilia/install/lib
./deqp-gles31 --deqp-visibility=hidden --deqp-case='*shared_var*atomic*'
This accounts for almost all of the shared_var failures. There are also these
2, which are probably unrelated, but figured I'd mention just in case:
Test case
'dEQP-GLES31.functional.compute.basic.shared_var_multiple_invocations'..
Compute shader compile time = 0.448000 ms
Link time = 2.081000 ms
Test case duration in microseconds = 4210 us
Fail (Comparison failed for Output.values[1])
Test case 'dEQP-GLES31.functional.compute.basic.shared_var_multiple_groups'..
Compute shader compile time = 0.446000 ms
Link time = 2.528000 ms
Test case duration in microseconds = 4595 us
Fail (Comparison failed for Output.values[0])
Included is the disassembly of one of the atomic fails, in case it's useful.</pre>
