With the misc device, we should end up using the result of get_arch_dma_ops(..) or dma-direct ops. This can allow us to have WC mappings in the guest after synchronization. Signed-off-by:

Modifying fb_ops directly to override fb_mmap with fb_deferred_io_mmap and then resetting it to NULL afterwards causes problems all over the place. First, it prevents making the fbops member of struct fb_info a const pointer, which means we can't make struct fb_ops const anywhere. Second, a few places have to go out of their way to restore the original fb_mmap pointer that gets reset to NULL. Since the only user of the fbops->fb_mmap hook is fb_mmap() in fbmem.c, call fb_deferred_io_mmap() directly when deferred IO is enabled, and avoid modifying fb_ops altogether. Simply use info->fbdefio to determine whether deferred IO should be used or not. This should be accurate enough for all use cases, although perhaps not pedantically correct. v2: Simplify considerably by calling fb_deferred_io_mmap() directly (Daniel, Ville) Cc: Jaya Kumar <jayalk@intworks.biz> Cc: linux-fbdev@vger.kernel.org Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by:

As mentioned by Christian, for drivers which support only primary nodes this changes the returned error from -EACCES into -EOPNOTSUPP/-ENOSYS. For others, this check in particular will be a noop.

bridge->next is only points to the new bridge if drm_bridge_attach() succeeds. No need to reset it manually here. Note that this change is part of the attempt to make the bridge chain a double-linked list. In order to do that we must patch all drivers manipulating the bridge->next field. Signed-off-by:

Previously, there was an omap panel-dpi driver that would read generic timings from the device tree and set the display timing accordingly. This driver was removed so the screen no longer functions. This patch modifies the panel-simple file to setup the timings to the same values previously used. Fixes: 8bf4b162 ("drm/omap: Remove panel-dpi driver") Signed-off-by:

This thing can get called several thousand times per LUT so seems like we want to inline it to: - avoid the function call overhead - allow constant folding A quick synthetic test (w/o any hardware interaction) with a ridiculously large LUT size shows about 50% reduction in runtime on my HSW and BSW boxes. Slightly less with more reasonable LUT size but still easily measurable in tens of microseconds. v2: Include drm_color_mgmt.h in the .rst (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by:
