Udl's GEM code and the generic SHMEM are almost identical. Replace the former with SHMEM. The dmabuf support in udl is being replaced with generic GEM PRIME functions. The main difference is in the caching flags for mmap pages. By default, SHMEM always sets (uncached) write combining. In udl's memory management code, only imported buffers use write combining. Memory pages of locally created buffer objects are mmap'ed with caching enabled. To keep the optimization, udl provides its own mmap function for GEM objects where it fixes up the mapping flags. v3: - restore udl vmap that enables caching v2: - remove obsolete code in a separate patch Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191107094307.19870-4-tzimmermann@suse.de |
