Add support for damage handling and deferred I/O to fbdev-dma. This enables fbdev-dma to support all DMA-memory-based DRM drivers, even such with a dirty callback in their framebuffers. The patch adds the code for deferred I/O and also sets a dedicated helper for struct fb_ops.fb_mmap that support coherent mappings. v3: - init fb_ops with FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS() (Javier) Signed-off-by:

Thomas Zimmermann authored
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 authored
Add a callback for drivers to provide framebuffer pages to fbdev's deferred-I/O helpers. Implementations need to acquire a reference on the page before returning it. Returning NULL generates a SIGBUS signal. This will be useful for DRM's fbdev emulation with GEM-shmem buffer objects. v2: - fix typo in commit message (Javier) Signed-off-by:

Unconditionally call get_page() after looking up a page from the framebuffer memory. Guarantees that we always hold a reference. This change also refactors the code such that it can support a driver-supplied get_page helper. This will be useful for DRM's fbdev emulation. Signed-off-by:

Clean up the pageref state as part of the lastclose helper. This only requires to clear the page's mapping field. The pageref and page can stay in place for the next opened instance of the frame- buffer file. With the change in the clean-up logic, there's no further need to look up pages during the lastclose cleanup. The code instead uses the existing pagerefs in its look-up table. It also avoids using smem_len, which some driver might not set correctly. v2: - fix typos in commit message (Javier) Signed-off-by:

Thomas Zimmermann authored
Set up struct fb_deferred_io_pageref in the new helper function fb_deferred_io_pageref_lookup(), which runs when the pageref is first taken. Remove the setup code from the rest of the code. At first, the code allocates the memory of all pageref structs. The setup of the various fields happens when the pageref is required. v2: - fix typo in commit message (Javier) Signed-off-by:

Framebuffer memory is allocated via vzalloc() from non-contiguous physical pages. The physical framebuffer start address is therefore meaningless. Do not set it. The value is not used within the kernel and only exported to userspace on dedicated ARM configs. No functional change is expected. v2: - refer to vzalloc() in commit message (Javier) Signed-off-by:

Having conditional around the of_node pointer of the drm_bridge structure is not necessary anymore, since drm_bridge structure always has the of_node member since the commit d8dfccde ("drm/bridge: Drop conditionals around of_node pointers"). So drop the conditional, please also note that this patch is following the convention used by driver core, see commit c9e358df ("driver-core: remove conditionals around devicetree pointers").
