H A D | drm_client.h | a8595556 Tue Nov 03 03:30:13 CST 2020 Thomas Zimmermann <tzimmermann@suse.de> drm/gem: Store client buffer mappings as struct dma_buf_map
Kernel DRM clients now store their framebuffer address in an instance of struct dma_buf_map. Depending on the buffer's location, the address refers to system or I/O memory.
Callers of drm_client_buffer_vmap() receive a copy of the value in the call's supplied arguments. It can be accessed and modified with dma_buf_map interfaces.
v6: * don't call page_to_phys() on framebuffers in I/O memory; warn instead (Daniel)
