+enum batch_kind {

• BATCH_CPU_MEMORY = 0,
• BATCH_MMIO,

+};

with 'CPU_MEMORY' (instead of plain 'MEMORY') implies future support of 'DEV_MEMORY'?

Maybe, but I don't have an immediate thought on this. CXL "MMIO" that is cachable is a thing but we can also label it as CPU_MEMORY.

We might have something for CC shared/protected memory down the road.

Thanks, Jason
