2016-10-12drm/amd/amdgpu: enable clockgating only after late initArindam Nath1-7/+7
Sometimes during multiple reboots, the system hangs during bootup. The issue is very random and happens once in around 50 reboots or so. It seems if clockgating is enabled before late init, the GFX engine sometimes does not respond. This patch changes the ordering a little so that both powergating and clockgating are enabled only after late init calls.

2016-10-12drm/amdgpu: use .early_unregister hook to remove DP AUX i2cGrazvydas Ignotas1-1/+12
When DisplayPort AUX channel i2c adapter is registered, drm_connector's kdev member is used as a parent, so we get sysfs structure like: /drm/card1/card1-DP-2/i2c-12 Because of that, there is a problem when drm core (and not the driver) calls drm_connector_unregister(), it removes parent sysfs entries ('card1-DP-2' in our example) while the i2c adapter is still registered. Later we get a WARN when we try to unregister the i2c adapter: WARNING: CPU: 3 PID: 1374 at fs/sysfs/group.c:243 sysfs_remove_group+0x14c/0x150 sysfs group ffffffff82911e40 not found for kobject 'i2c-12' To fix it, we can use the .early_unregister hook to unregister the i2c adapter before drm_connector's sysfs is torn down.

Since fence_wait_timeout_reservation_object_wait_timeout_rcu() with a timeout of 0 becomes reservation_object_test_signaled_rcu(), we do not need to handle such conversion in the caller.

If this happens (and it recently did), we free a structure while part of it is still in use, which results in non-obvious crashes.
