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.
