[Intel-gfx] [RFC 00/13] drm/i915/lmem: Enable device memory support for DG2

[Ayaz A Siddiqui]

There are few changes for device memory in Gen12.5+ platforms.

1. Minimum page size has been changed to 64KB.
2. Compression control state (CCS) moved from user-space manages
AUX page tables to flat indexed region of memory. This Flat index
memory is referred as Flat CCS.
3. Due to different page sizes of LMEM(64K) and SMEM(4K), a mix of
LMEM and SMEM pages are not supported in a single page table.

This series is containing patches to cover all the above changes.
 
Todo:
  Handling of Flat CCS during migration buffers from System
 to device memory and vice versa.
