Why do you need error-correction code for a debugging feature though? I would not protect debug registers with a hash.

Bc you are DMA-ing the raw bits into cache with the GPU, but the CPU is going to check those ECC codes on read as the caches on Apple SoC's are ECC-native. It's an integrity 'protection' not a security 'protection'
