H A D | ingenic-drm.h | 4a791cb6 Sun May 23 12:04:15 CDT 2021 Paul Cercueil <paul@crapouillou.net> drm/ingenic: Add option to alloc cached GEM buffers
Alloc GEM buffers backed by noncoherent memory on SoCs where it is actually faster than write-combine.
This dramatically speeds up software rendering on these SoCs, even for tasks where write-combine memory should in theory be faster (e.g. simple blits).
v3: The option is now selected per-SoC instead of being a module parameter.
v5: - Fix drm_atomic_get_new_plane_state() used to retrieve the old state - Use custom drm_gem_fb_create() - Only check damage clips and sync DMA buffers if non-coherent buffers are used
