2017-10-12drm: Pass struct drm_file * to __drm_mode_object_find [v2]Keith Packard
This will allow __drm_mode_object_file to be extended to perform access control checks based on the file in use. v2: Also fix up vboxvideo driver in staging [airlied: merging early as this is an API change] Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2017-06-20drm: More links for gamma support helpersDaniel Vetter
It's not obvious that when using the new color manager stuff you still need to wire up the legacy helper to get legacy LUT support. Improve this with more links. drm_crtc_funcs->gamma_set already explains this properly.

2017-04-06drm/atomic-helper: Remove legacy backoff hack from gamma_setDaniel Vetter
Another one knocked down. With this we can also remove the temporary hack in the gamma_set ioctl.

2017-04-06drm: Add acquire ctx to ->gamma_set hookDaniel Vetter
Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.

2017-04-06drm: Add explicit acquire ctx handling around ->gamma_setDaniel Vetter
Just the groundwork to prepare for adding the acquire cxt parameter to the ->gamma_set hook. Again we need a temporary hack to fill out mode_config.acquire_ctx until the atomic helpers are switched over.

2017-04-05drm: Only take crtc lock in get_gamma ioctlDaniel Vetter
We don't call into drivers at all here, this is enough. Also, we can reduce the critical section a bit to simplify the code. crtc->gamma_size is set up once at driver load and then invariant, so also doesn't need any protection.

2017-01-31drm/color: un-inline drm_color_lut_extract()Jani Nikula
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: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485531291-24821-1-git-send-email-jani.nikula@intel.com
2016-12-30drm/doc: use preferred struct reference in kernel-docDaniel Vetter
sed -e 's/\( \* .*\)struct &\([_a-z]*\)/\1\&struct \2/' -i Originally I wasnt a friend of this style because I thought a line-break between the "&struct" and "foo" part would break it. But a quick test shows that " * &struct \n * foo\n" works pefectly well with current kernel-doc. So time to mass-apply these changes!
