[PATCH 5/5] drm/ingenic: Add option to alloc cached GEM buffers

2020-11-02 Thread Paul Cercueil
With the module parameter ingenic-drm.cached_gem_buffers, it is possible to specify that we want GEM buffers backed by non-coherent memory. This dramatically speeds up software rendering on Ingenic SoCs, even for tasks where write-combine memory should in theory be faster (e.g. simple blits).
