408bd841ad drm/amdgpu: Improve ras fatal error handling function
In multi-gpu case, a fatal error will generate several
fatal error interrupts. After improving this function,
the ras module can reuse this function to only
handle the first interrupt.

V3:
  Initialize event_id using RAS_EVENT_INVALID_ID.

4b6ec94fda drm/amd: Drop calls to restore power limit and clock from smu_resume()
User requested power limits and clock settings are already restored as
part of smu_restore_dpm_user_profile(). It's unnecessary to call the
same restore as part of smu_resume().

Revert the following commits to drop that extra restore:
commit ed4efe426a ("drm/amd: Restore cached power limit during resume")
commit 796ff8a7e0 ("drm/amd: Restore cached manual clock settings during resume")
commit f9b80514a7 ("drm/amd: Only restore cached manual clock settings in restore if OD enabled")

8e8691ecee drm/amd/display: Driver implementation for cursor offloading to DMU
[Why]
We require an interlock between driver and firmware for upcoming
features and given that this could possibly happen on any single
cursor programming call (and that we can't asynchronously wait for
firmware to respond because of it) we'd be regressing cursor performance
by at least an extra 40us per call.

When we could possibly have cursor update every 20us - 100s from high
frequency gaming mice this means that we'd be stuttering or dropping
updates and impacting overall cursor performance.

We want a solution that can:

1. Interlock between other firmware features
2. Not stall out or require the DMCUB lock for every single update

[How]
When cursor offloading is enabled and supported by an ASIC driver will
route the cursor programming through to DMU as part of the regular
DC stream cursor programming interfaces for attributes and position.

The atomic pipe programming version will not be updated: this will still
follow the existing programming path by keeping track of a field that
specifies when the register writes should be deferred to DMU.

Cursor locking is not required when cursor offload is in progress since
the updates are consolidated and processed by DMU once at the end
of the frame in a periodic manner.

The shared buffer the firmware queries from is allocated along with the
rest of the scratch state region in an area that's accessible by
both firmware and driver.

The size of the cursor offload (v1) state will not change, but it does
have a unique union per ASIC version with room for expansion if needed.

When firmware features notifying DMU of DRR updates are not enabled we
now send an explicit vtotal min/max update via driver to DMU firmware
whenever the vtotal max changes. This is to allow the cursor programming
to determine the appropriate latch update point offset from vupdate.

d04eb0c402 drm/amd/display: Prevent Gating DTBCLK before It Is Properly Latched
[why]
1. With allow_0_dtb_clk enabled, the time required to latch DTBCLK to 600 MHz
depends on the SMU. If DTBCLK is not latched to 600 MHz before set_mode completes,
gating DTBCLK causes the DP2 sink to lose its clock source.

2. The existing DTBCLK gating sequence ungates DTBCLK based on both pix_clk and ref_dtbclk,
but gates DTBCLK when either pix_clk or ref_dtbclk is zero.
pix_clk can be zero outside the set_mode sequence before DTBCLK is properly latched,
which can lead to DTBCLK being gated by mistake.

[how]
Consider both pixel_clk and ref_dtbclk when determining when it is safe to gate DTBCLK;
this is more accurate.

13ab3a8f9a drm/amd/display: lttpr cap should be nrd cap in bw_alloc mode
[WHY]
When bw allocation mode enabled, dpia may reports lttpr cap with
reduced common cap. It would cause driver not start pre-training with
max available bandwidth.

[How]
When bw allocation mode enabled, use NRD cap as lttpr cap.

6d92c4d030 drm/amd/display: Rename FAMS2 global control lock to DMUB HW control lock
[Why]
FAMS2 dictates whether the inbox0 HW lock is required, but it is not the
only feature that may determine this.

In order to leverage the faster inbox0 HW lock in place of the inbox1
ringbuffer based control lock it's desirable to utilize the HWSS
based locking protocol FAMS2 has already implemented.

[How]
Rename the FAMS2 global control lock to DMUB HW control lock.

This is purely a refactor with no functional change, the logic that will
determine which features need to enable this HW lock will be added in a
future commit.
