[PATCH 0/4] drm/gpuvm: Add support for single-page-filled mappings

2025-02-02 Thread Asahi Lina
Some hardware requires dummy page mappings to efficiently implement Vulkan sparse features. These mappings consist of the same physical memory page, repeated for a large range of address space (e.g. 16GiB). Add support for this to drm_gpuvm. Currently, drm_gpuvm expects BO ranges to correspond 1:1
