on bug 103697
from O Heid
I checked back with AMD and they say that there is hardware support for 64kB shared memory. This actually gets exposed in OpenCL and ROCm/HC. The 2016 AMD GCN3 manual wrongly states it is only 32kB, but the AMD Vega ISA reference guide has the correct 64kB LDS size. So it seems the restriction is due to the mesa software stack, not due to hardware. Could you please raise the bar back to 64kB? I wouldn't ask if it wouldn't hit me with with a 2x performance penalty...
