Yunxiang Li bebf2ebd70 drm: make drm-active- stats optional
When memory stats is generated fresh everytime by going though all the
BOs, their active information is quite easy to get. But if the stats are
tracked with BO's state this becomes harder since the job scheduling
part doesn't really deal with individual buffers.

Make drm-active- optional to enable amdgpu to switch to the second
method.

Imre Deak 1d985ddabb drm/connector: Add a way to init/add a connector in separate steps
Atm when the connector is added to the drm_mode_config::connector_list,
the connector may not be fully initialized yet. This is not a problem
for static connectors initialized/added during driver loading, for which
the driver ensures that look-ups via the above list are not possible
until all the connector and other required state is fully initialized
already. It's also not a problem for user space looking up either a
static or dynamic (see what this is below) connector, since this will be
only possible once the connector is registered.

A dynamic - atm only a DP MST - connector can be initialized and added
after the load time initialization is done. Such a connector may be
looked up by in-kernel users once it's added to the connector list. In
particular a hotplug handler could perform a detection on all the
connectors on the list and hence find a connector there which isn't yet
initialized. For instance the connector's helper hooks may be unset,
leading to a NULL dereference while the detect helper calls the
connector's drm_connector_helper_funcs::detect() or detect_ctx()
handler.

To resolve the above issue, add a way for dynamic connectors to
separately initialize the DRM core specific parts of the connector
without adding it to the connector list - by calling the new
drm_connector_dynamic_init() - and to add the connector to the list
later once all the initialization is complete and the connector is
registered - by calling the new drm_connector_dynamic_register().

Adding the above 2 functions was also motivated to make the distinction
of the interface between static and dynamic connectors clearer: Drivers
should manually initialize and register only dynamic connectors (with
the above 2 functions). A driver should only initialize a static
connector (with one of the drm_connector_init*, drmm_connector_init*
functions) while the registration of the connector will be done
automatically by DRM core.

v2: (Jani)
- Let initing DDC as well via drm_connector_init_core().
- Rename __drm_connector_init to drm_connector_init_core_and_add().

v3:
- Rename drm_connector_init_core() to drm_connector_dynamic_init().
  (Sima)
- Instead of exporting drm_connector_add(), move adding the connector
  to the registration step via a new drm_connector_dynamic_register().
  (Sima)
- Update drm_connector_dynamic_init()'s function documentation and the
  commit log according to the above changes.
- Update the commit log describing the problematic scenario during
  connector detection. (Maxime)

Dmitry Baryshkov df7c8e3dde drm/connector: add mutex to protect ELD from concurrent access
The connector->eld is accessed by the .get_eld() callback. This access
can collide with the drm_edid_to_eld() updating the data at the same
time. Add drm_connector.eld_mutex to protect the data from concurrenct
access. Individual drivers are not updated (to reduce possible issues
while applying the patch), maintainers are to find a best suitable way
to lock that mutex while accessing the ELD data.

Add a Synopsys Designware MIPI DSI host DRM bridge driver for their
DSI2 host controller, based on the Rockchip version from the driver
rockchip/dw-mipi-dsi2.c in their vendor-kernel with phy & bridge APIs.

While the driver is heavily modelled after the previous IP, the register
set of this DSI2 controller is completely different and there are also
additional properties like the variable-width phy interface.

Imre Deak a6fa67d26d drm/dp_mst: Fix resetting msg rx state after topology removal
If the MST topology is removed during the reception of an MST down reply
or MST up request sideband message, the
drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset
from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with
the reading/parsing of the message from another thread via
drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is
possible since the reader/parser doesn't hold any lock while accessing
the reception state. This in turn can lead to a memory corruption in the
reader/parser as described by commit bd2fccac61 ("drm/dp_mst: Fix MST
sideband message body length check").

Fix the above by resetting the message reception state if needed before
reading/parsing a message. Another solution would be to hold the
drm_dp_mst_topology_mgr::lock for the whole duration of the message
reception/parsing in drm_dp_mst_handle_down_rep() and
drm_dp_mst_handle_up_req(), however this would require a bigger change.
Since the fix is also needed for stable, opting for the simpler solution
in this patch.

Thomas Weißschuh 22e5c7ae12 drm: Add panel backlight quirks
Panels using a PWM-controlled backlight source do not have a standard
way to communicate their valid PWM ranges.
On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an
older device can be retrofitted with newer panels.

Add a quirk infrastructure with which the minimum valid backlight value
can be maintained as part of the kernel.

Daniele Ceraolo Spurio db0fc586ed drm/i915/gsc: ARL-H and ARL-U need a newer GSC FW.
All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.

Thomas Zimmermann bf17766f10 drm/client: Move suspend/resume into DRM client callbacks
Suspend and resume is still tied to fbdev emulation. Modeset helpers
and several drivers call drm_fb_helper_set_suspend_unlocked() to inform
the fbdev client about suspend/resume events.

To make it work with arbitrary clients, add per-client callback
functions for suspend and resume. Implement them for fbdev emulation
with the existing drm_fb_helper_set_suspend_unlocked(). Then update
DRM's modeset helpers to call the new interface.

Clients that are not fbdev can now implement suspend/resume to their
requirements.

The callback parameter holds_console_lock is a workaround for i915,
radeon and xe, which possibly call the interface while having the
console lock acquired. Even though the commit doesn't modify these
drivers, it already adds the flag to avoid churn later on. New code
should not hold the console lock.

v4:
- clarify holds_console_lock in commit description (Jonathan)

Tvrtko Ursulin 134e71bd1e drm/sched: Further optimise drm_sched_entity_push_job
Having removed one re-lock cycle on the entity->lock in a patch titled
"drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit
larger refactoring we can do the same optimisation on the rq->lock.
(Currently both drm_sched_rq_add_entity() and
drm_sched_rq_update_fifo_locked() take and release the same lock.)

To achieve this we make drm_sched_rq_update_fifo_locked() and
drm_sched_rq_add_entity() expect the rq->lock to be held.

We also align drm_sched_rq_update_fifo_locked(),
drm_sched_rq_add_entity() and
drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a
parameter to the latter.

v2:
 * Fix after rebase of the series.
 * Avoid naming inconsistency between drm_sched_rq_add/remove. (Christian)

When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:

	spin_lock(&entity->rq_lock);
	spin_lock(&entity->rq->lock);

Rename drm_sched_entity.rq_lock to improve readability. While at it,
re-order that struct's members to make it more obvious what the lock
protects.

v2:
 * Rename some rq_lock straddlers in kerneldoc, improve commit text. (Philipp)

Tvrtko Ursulin a6f46283e9 drm/sched: Re-order struct drm_sched_rq members for clarity
Current kerneldoc for struct drm_sched_rq incompletely documents what
fields are protected by the lock.

This is not good because it is misleading.

Lets fix it by listing all the elements which are protected by the lock.

While at it, lets also re-order the members so all protected by the lock
are in a single group.

v2:
 * Refer variables by kerneldoc syntax, more verbose commit text. (Philipp)

Tvrtko Ursulin d42a254633 drm/sched: Optimise drm_sched_entity_push_job
In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.

We can avoid that design inelegance, and also have a miniscule
efficiency improvement on the submit from idle path, by introducing a new
drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to
its callers.

v2:
 * Remove drm_sched_rq_update_fifo() altogether. (Christian)

v3:
 * Improved commit message. (Philipp)
