drm/i915: Move CSB MMIO reads out of the execlists lock
By reading the CSB (slow MMIO accesses) into a temporary local
buffer we can decrease the duration of holding the execlist
lock.
Main advantage is that during heavy batch buffer submission we
reduce the execlist lock contention, which should decrease the
latency and CPU usage between the submitting userspace process
and interrupt handling.
Downside is that we need to grab and relase the forcewake twice,
but as the below numbers will show this is completely hidden
by the primary gains.
Testing with "gem_latency -n 100" (submit batch buffers with a
hundred nops each) shows more than doubling of the throughput
and more than halving of the dispatch latency, overall latency
and CPU time spend in the submitting process.
Submitting empty batches ("gem_latency -n 0") does not seem
significantly affected by this change with throughput and CPU
time improving by half a percent, and overall latency worsening
by the same amount.
Above tests were done in a hundred runs on a big core Broadwell.
v2:
* Overflow protection to local CSB buffer.
* Use closer dev_priv in execlists_submit_requests. (Chris Wilson)

drm/i915: Fix race condition in intel_dp_destroy_mst_connector()
After unplugging a DP MST display from the system, we have to go through
and destroy all of the DRM connectors associated with it since none of
them are valid anymore. Unfortunately, intel_dp_destroy_mst_connector()
doesn't do a good enough job of ensuring that throughout the destruction
process that no modesettings can be done with the connectors. As it is
right now, intel_dp_destroy_mst_connector() works like this:
* Take all modeset locks
* Clear the configuration of the crtc on the connector, if there is one
* Drop all modeset locks, this is required because of circular
dependency issues that arise with trying to remove the connector from
sysfs with modeset locks held
* Unregister the connector
* Take all modeset locks, again
* Do the rest of the required cleaning for destroying the connector
* Finally drop all modeset locks for good
This only works sometimes. During the destruction process, it's very
possible that a userspace application will attempt to do a modesetting
using the connector. When we drop the modeset locks, an ioctl handler
such as drm_mode_setcrtc has the oppurtunity to take all of the modeset
locks from us. When this happens, one thing leads to another and
eventually we end up committing a mode with the non-existent connector:
[drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* failed to enable link training
[drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f
[drm:intel_dp_start_link_train [i915]] *ERROR* failed to start channel equalization
[drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f
[drm:intel_mst_pre_enable_dp [i915]] *ERROR* failed to allocate vcpi
And in some cases, such as with the T460s using an MST dock, this
results in breaking modesetting and/or panicking the system.
To work around this, we now unregister the connector at the very
beginning of intel_dp_destroy_mst_connector(), grab all the modesetting
locks, and then hold them until we finish the rest of the function.

drm/vc4: Recognize a more specific compatible string for V3D.
The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D. Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.
