2026-03-16drm/{i915,xe}: move framebuffer bo to parent interfaceJani Nikula1-1/+0
Add .framebuffer_init, .framebuffer_fini and .framebuffer_lookup to the bo parent interface. While they're about framebuffers, they're specifically about framebuffer objects, so the bo interface is a good enough fit, and there's no need to add another interface struct.

2026-03-16drm/{i915, xe}/bo: move display bo calls to parent interfaceJani Nikula1-0/+1
Continue i915 and xe separation from display by moving the bo calls to the display parent interface. Instead of adding all these functions to intel_parent.[ch], reuse the now vacated intel_bo.[ch], and avoid mass renames to calls of these functions. This is similar to intel_display_rpm.[ch]. Make many of the hooks optional to avoid having to implement dummy functions in xe. Indeed now we can remove many of the existing dummy functions.

2026-03-11drm/{i915, xe}/frontbuffer: move frontbuffer handling to parent interfaceJani Nikula1-0/+1
Move the get/put/ref/flush_for_display calls to the display parent interface. For i915, move the hooks next to the other i915 core frontbuffer code in i915_gem_object_frontbuffer.c. For xe, add new file xe_frontbuffer.c for the same. Note: The intel_frontbuffer_flush() calls from i915_gem_object_frontbuffer.c will partially route back to i915 core via the parent interface.

Do not add separate write and write_timeout calls in the interface. Instead, handle the default 1 ms timeout in the intel_parent.c glue layer.

Now that xe_pci.c calls the rebar directly, it doesn't make sense to keep it in xe_vram.c since it's closer to the PCI initialization than to the VRAM. Move it to its own file. While at it, add a better comment to document the possible values for the vram_bar_size module parameter.

2025-12-12drm/xe: Create page reclaim list on unbindBrian Nguyen1-0/+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.
