As evidenced by in-field reports, this panel shipped on pompom but we never added the ID and thus we're stuck w/ conservative timings. The panel was part of early patches but somehow got left off in the end. :( Add it in now. For future reference, EDID from this panel is: 00ffffffffffff002c82121200000000 321e0104951a0e780ae511965e55932c 19505400000001010101010101010101 010101010101a41f5686500084302820 55000090100000180000000000000000 00000000000000000000000000000000 000000000000000000000000000000fe 004b443131364e3039333041313600f6 We use the ASCII string from decoding the EDID ("KD116N0930A16") as the panel name.

Rewrite some docs that are not up-to-date any longer. Remove the TODO item for fbdev-generic conversion, as the helper has been replaced. Make documentation for DMA, SHMEM and TTM emulation available. Signed-off-by:

Only TTM-based drivers use fbdev-generic. Rename it to fbdev-ttm and change the symbol infix from _generic_ to _ttm_. Link the source file into TTM helpers, so that it is only build if TTM-based drivers have been selected. Select DRM_TTM_HELPER for loongson. Signed-off-by:

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:

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:
