Radeon ROCm 3.5 Released With New Features But Still No Navi Support
Hawaii (gfx7) had an early version of MEC with a fixed microcode store in the MEC block, while the later gfx8 parts could support larger microcode images by executing directly out of VRAM via an instruction cache. I had not heard about Hawaii support being broken until today but will take a look. It was always a challenge to fit even stripped-down ROCm functionality into the fixed microcode store so it's possible that we just outgrew it.
Support of gfx7 in ROCm would very valuable for those people with S8150 and similar cards. These GPUs are quite capable and with HIP support they could be very efficient for many.
