drm/legacy: move init/destroy of struct members into legacy file

2019-04-24T02:32:18+00:00

This introduces drm_legacy_misc.c as a place for some misc legacy code, eventually I want to give the option to remove this from the build. Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm/drv: Fix incorrect resolution of merge conflict

2019-04-17T20:42:22+00:00

Commit f06ddb53096b ("BackMerge v5.1-rc5 into drm-next") incorrectly resolved a merge conflict related to a patch having been merged twice: - commit 3f04e0a6cfeb ("drm: Fix drm_release() and device unplug") introduced as a standalone fix via drm-fixes branch, - commit 1ee57d4d75fb ("drm: Fix drm_release() and device unplug") applied as patch 1/2 of a series on drm-next branch. That incorrect resolution of the conflict effectively reverted a change introduced to drivers/gpu/drm/drm_drv.c by patch 2/2 of that series - commit ba3bf37e150a ("drm/drv: drm_dev_unplug(): Move out drm_dev_put() call"). Fix it.

drm: Fix drm_release() and device unplug

2019-03-25T05:58:05+00:00

If userspace has open fd(s) when drm_dev_unplug() is run, it will result in drm_dev_unregister() being called twice. First in drm_dev_unplug() and then later in drm_release() through the call to drm_put_dev(). Since userspace already holds a ref on drm_device through the drm_minor, it's not necessary to add extra ref counting based on no open file handles. Instead just drm_dev_put() unconditionally in drm_dev_unplug(). We now have this: - Userpace holds a ref on drm_device as long as there's open fd(s) - The driver holds a ref on drm_device as long as it's bound to the struct device When both sides are done with drm_device, it is released.
