I fixed my it and locally I have the following results: ./deqp-gles31 -n dEQP-GLES31.functional.ssbo.* Test run totals: Passed: 2061/2061 (100.0%) Failed: 0/2061 (0.0%) Not supported: 0/2061 (0.0%) Warnings: 0/2061 (0.0%) It with mesa assertion fix and with deqp fix. Without the mesa fix it is still crashes even if the deqp fix is applied: Test case 'dEQP-GLES31.functional.ssbo.layout.random.all_per_block_buffers.18'.. ir_variable has maximum access out of bounds (1 vs 0) Aborted (core dumped) deqp: <a href="https://github.com/asimiklit/deqp/commit/91cff8150944213f6da533e281ee76d95ca00f21">https://github.com/asimiklit/deqp/commit/91cff8150944213f6da533e281ee76d95ca00f21</a> mesa: <a href="https://gitlab.freedesktop.org/GL/mesa/commit/526a9fee0e40a450bc71092b27a3b89cbbf93fd7">https://gitlab.freedesktop.org/GL/mesa/commit/526a9fee0e40a450bc71092b27a3b89cbbf93fd7</a> So I am actually not 100% sure about which binding point should be assigned for BlockB[1] instance in the following case: layout(local_size_x = 1) in; layout(packed, binding = 0) buffer BlockB { float b[1]; } blockB[2]; void main (void) { blockB[1].b[0] = 77777.77777; } But according to next comment it should be 0 because of the BlockB[0] was optimized and there is the BlockB[1] only: /* The ARB_shading_language_420pack spec says: * * If the binding identifier is used with a uniform block instanced as * an array then the first element of the array takes the specified * block binding and each subsequent element takes the next consecutive * uniform block binding point. */ <a href="https://gitlab.freedesktop.org/mesa/mesa/blob/master/src/compiler/glsl/link_uniform_blocks.cpp#L279-310">https://gitlab.freedesktop.org/mesa/mesa/blob/master/src/compiler/glsl/link_uniform_blocks.cpp#L279-310</a> Mark is it possible to check both patches under Intel CI? mesa: fork: <a href="https://gitlab.freedesktop.org/asimiklit/mesa/">https://gitlab.freedesktop.org/asimiklit/mesa/</a> branch: max_array_access deqp: fork: <a href="https://github.com/asimiklit/deqp/">https://github.com/asimiklit/deqp/</a> branch: array_instance_binding_fix</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
