You can still allocate a smaller scratch buffer. This should limit the number of waves in hw. TMPRING_SIZE.WAVES should be adjusted accordingly. We can also decrease the size of scratch based on the max number of waves with the given register and LDS usage. si_shader_dump_stats calculates the max number of waves. You just need to: - set TMPRING_SIZE.WAVES = MIN2(32, max_simd_waves * 4) - allocate scratch for TMPRING_SIZE.WAVES waves per CU (instead of 32) - si_context::scratch_waves can be moved to si_shader in some form (e.g. max_scratch_bytes_per_cu) Marek _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
