2025-12-12drm/xe: Create page reclaim list on unbindBrian Nguyen-0/+1
Page reclaim list (PRL) is preparation work for the page reclaim feature. The PRL is firstly owned by pt_update_ops and all other page reclaim operations will point back to this PRL. PRL generates its entries during the unbind page walker, updating the PRL. This PRL is restricted to a 4K page, so 512 page entries at most. v2: - Removed unused function. (Shuicheng) - Compacted warning checking, update commit message, spelling, etc. (Shuicheng, Matthew B) - Fix kernel docs - Moved PRL max entries overflow handling out from generate_reclaim_entry to caller (Shuicheng) - Add xe_page_reclaim_list_init for clarity. (Matthew B) - Modify xe_guc_page_reclaim_entry to use macros for greater flexbility. (Matthew B) - Add fallback for PTE outside of page reclaim supported 4K, 64K, 2M pages (Matthew B) - Invalidate PRL for early abort page walk. - Removed page reclaim related variables from tlb fence (Matthew Brost) - Remove error handling in *alloc_entries failure. (Matthew B) v3: - Fix NULL pointer dereference check. - Modify reclaim_entry to QW and bitfields accordingly. (Matthew B) - Add vm_dbg prints for PRL generation and invalidation. (Matthew B) v4: - s/GENMASK/GENMASK_ULL && s/BIT/BIT_ULL (CI) v5: - Addition of xe_page_reclaim_list_is_new() to avoid continuous allocation of PRL if consecutive VMAs cause a PRL invalidation. - Add xe_page_reclaim_list_valid() helpers for clarity.
