dma-buf: cleanup dma_buf_export() to make it easily extensible

2015-04-21T09:17:16+00:00

At present, dma_buf_export() takes a series of parameters, which makes it difficult to add any new parameters for exporters, if required. Make it simpler by moving all these parameters into a struct, and pass the struct * as parameter to dma_buf_export(). While at it, unite dma_buf_export_named() with dma_buf_export(), and change all callers accordingly.

drm/udl: properly set active_16 flag in udl_crtc_page_flip(). (v2)

2015-01-31T00:12:23+00:00

When page flipping, we need to mark the new fb as active and unmark the active flag for the old fb (if different). Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: optimize udl_compress_hline16 (v2)

2015-01-31T00:08:47+00:00

The run-length encoding algorithm should compare 16-bit encoded pixel values instead of comparing raw pixel values. It allows pixels with similar but different colors to be encoded as repeat pixels, and thus potentially save USB bandwidth.

drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03+00:00

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

drm/udl: properly check for error pointers

The drm_prime_pages_to_sg() function never returns NULL pointers, only error pointers and valid pointers. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: handle page mapping in dmabuf export.

drm/udl: Deletion of an unnecessary check before the function call "vunmap"

2014-11-21T02:16:35+00:00

The vunmap() function performes also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

drm/udl: add support to export a handle to a FD on UDL.

Only importing an FD to a handle is currently supported on UDL, but the exporting functionality is equally useful. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: add cache flags definitions for udl_gem_object

By default set udl_gem_object as cacheable, but set WC flag when attaching dmabuf. In udl_gem_mmap() update cache attributes based on the flags, similar to exynos_drm_gem_mmap().

drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-04T23:14:55+00:00

Just a bit of OCD cleanup on headers - this function isn't the core interface any more but just a helper for drivers who haven't yet transitioned to universal planes. Put the declaration at the right spot and sprinkle necessary #includes over all drivers. Maybe this helps to encourage driver maintainers to do the switch. v2: Fix #include ordering for tegra, reported by 0-day builder. v3: Include required headers, reported by Thierry.
