Thomas Zimmermann	150f431a08	drm/fbdev: Add fbdev-shmem ... Add an fbdev emulation for SHMEM-based memory managers. The code is similar to fbdev-generic, but does not require an additional shadow buffer for mmap(). Fbdev-shmem operates directly on the buffer object's SHMEM pages. Fbdev's deferred-I/O mechanism updates the hardware state on write operations. The memory pages of GEM SHMEM cannot be detected by fbdefio. Therefore fbdev-shmem implements the .get_page() hook in struct fb_deferred_io. The fbdefio helpers call this hook to retrieve the page directly from fbdev-shmem instead of trying to detect it internally. v3: - clarify on get_page mechanism in commit description (Javier) v2: - use drm_driver_legacy_fb_format() (Geert) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240419083331.7761-9-tzimmermann@suse.de	2024-05-02 11:33:15 +02:00
