Rationale goes here.
Is this wise? HWSP is very frequently read by the CPU, and expected to
be cached on the CPU.
What do the performance profiles indicate?
Do you have a recommendation for an existing selftest or IGT to help
measure this?
Also are you suggesting moving this to system memory, or just using a
different mapping type, if it's placed in local memory? Or maybe try
both? Although I'm pretty sceptical about !wc for local memory.
