Subject: [PATCH 4/8] drm: Allow drm_mode_object_find() to look up an object of any type
Date: Wed, 28 May 2014 19:57:21 -0400	[thread overview]
Message-ID: <1401321445-31906-5-git-send-email-robdclark@gmail.com> (raw)
In-Reply-To: <1401321445-31906-1-git-send-email-robdclark@gmail.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

To avoid having to pass object types from userspace for atomic mode
setting ioctl, allow drm_mode_object_find() to look up an object of any
type. This will only work as long as the all object types share the ID
space.

2014-05-29 12:59       ` [PATCH 1/2] v2 (Daniel): - Readd lost include. - Drop all the additional complexity which we only need later: The basic ww dance only requires the lock list and the contended pointer, nothing more. Some of the stuff also looks very suspicious. - Improve the contended checks a bit to make sure we only get an -EALREADY when we expect it. - Add an interruptible backoff function just to be complete (since otherwise the interruptible locking function makes 0 sense at all). - Inline the slowpath (due to the above). - Move ww_acquire_fini into drm_modeset_acquire_fini. I suspect this has been due to the confusion about the lifetime of the acquire ctx wrt the locking retry loop. - Drop uapi changes, they really shouldn't be in this patch. - s/!ret/ret == 0/ because I got confused - I tend to use !ret only for booleans or pointers, not for errno integer return values Daniel Vetter
