drm-mm.rst contains some unformatted dump of the vm_operations_struct structure. Add some C formatting around it and some context for the dump. While there, update the structure to resemble the new signature for the fault handler after commit 25d3db7600b8 (mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf). Signed-off-by:

The function is not that big, but it's also not used for anything performance critical. Make it a normal function. As a side effect, this apparently makes sparse smarter about what it's doing, and gets rid of the warning: ./include/drm/drm_color_mgmt.h:53:28: warning: shift too big (4294967295) for type unsigned long ./include/drm/drm_color_mgmt.h:53:28: warning: cast truncates bits from constant value (8000000000000000 becomes 0) v2: rebased Cc: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by:

drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so it's not necessary to call drm_debugfs_remove_files().

Instead of having the drivers call drm_debugfs_remove_files() in their drm_driver->debugfs_cleanup hook, do it automatically by traversing minor->debugfs_list. Also use debugfs_remove_recursive() so drivers who add their own debugfs files don't have to keep track of them for removal. Signed-off-by:

CEA-861-F tells us: "When transmitting any RGB colorimetry, the Source should set the YQ-field to match the RGB Quantization Range being transmitted (e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB, set YQ=1) and the Sink shall ignore the YQ-field." So let's go ahead and do that. Perhaps there are sinks that don't ignore the YQ as they should for RGB? I wasn't able to find similar text in CEA-861-E, so it would seem to be a fairly "recent" addition. Signed-off-by:

HDMI 2.0 recommends that we set the Q bits in the AVI infoframe even when the sink does not support quantization range selection (QS=0). According to CEA-861 we can do that as long as the Q we send matches the default quantization range for the mode. Previously I think I had misread the spec as saying that you can't send a non-zero Q at all when QS=0. But that's not what the spec actually says. v2: Fix typo in commit message (Jani) Signed-off-by:

Pull the logic to populate the quantization range information in the AVI infoframe into a small helper. We'll be adding a bit more logic to it, and having it in a central place seems like a good idea since it's based on the CEA-861 spec. Signed-off-by:

Use the same trick we used for i915 when we still had ums support: Just initialize the agp support unconditionally in the driver load function. Unfortunately that means we need to export drm_agp_init again, but I think that's a lesser evil. Acked-by:
