There is no need to explicitly initiate a register transfer and turn off the DCU after initializing the plane registers. In fact, this is harmful and leads to unnecessary flickers if the DCU has been left on by the bootloader. Signed-off-by:

Do not use encoder disable/enable callbacks to control bypass mode as this seems to mess with the signals not liked by displays. This also makes more sense since the encoder is already defined to be parallel RGB/LVDS at creation time. Signed-off-by:

UVD and VCE CG are handled specially, however the previous fix for this skipped late init for those blocks rather than just CG. Just protect the CG function call. No functional change since UVD and VCE don't currently utilize a late_init function. Reviewed-by:

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. Reviewed-by:

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.

If we run out of enough aperture space to fit the entire object, we fallback to trying to insert a single page. However, if that also fails, we currently fail to userspace with an unexpected ENOSPC. (ENOSPC means to userspace that their batch could not be fitted within the GTT.) Prior to commit e8cb909a ("drm/i915: Fallback to single page GTT mmappings for relocations") the approach is to fallback to using the slow CPU relocation path in case of iomapping failure, and that is the behaviour we need to restore.

In order not to trigger hangcheck on a idle-but-waiting engine, we need to distinguish between the pending request queue and the actual execution queue. This is done later in "drm/i915: Enable multiple timelines" but for now we need a temporary fix to prevent blaming the wrong engine for a GPU hang. (Note that this causes a temporary subtle change in how we decide when to allow a waitboost to be re-awarded back to the waiter, the temporary effect is that if the wait is upon the most current execution the wait is given for free, instead of checking to see if the client stalled itself. This will be repaired in "drm/i915: Enable multiple timelines".)

We can't rely on connector->status in the detect() hook if the long hpd was already handled by the dig_port_work as that won't update connector->status. Thus we have to defer the long hpd handling entirely until the hotplug work runs to avoid the double long hpd handling the "detect_done" flag is trying to prevent. We'll start to depend on connector->status being up to date in a following patch.

On Braswell, at least, we observe that the context image is written in multiple phases. The first phase is to clear the register state, and subsequently rewrite it. A GPU reset at the right moment can interrupt the context update leaving it corrupt, and our update of the RING_HEAD is not sufficient to restart the engine afterwards. To recover, we need to reset the registers back to their original values. The context state is lost. What we need is a better mechanism to serialise the reset with pending flushes from the GPU.
