drm/i915/mtl: Remove the 'force_probe' requirement for Meteor Lake
Meteor Lake has demonstrated consistent stability for some time.
All user-space API modifications tide to its core platform
functions are operational.
The necessary firmware components are set up and comprehensive
testing has been condused over a period.
Given the recent faborable CI results, as well, we believe it's
time to eliminate the 'force_probe' prerequisite and activate the
platform by default.

Merge tag 'drm-habanalabs-next-2023-10-10' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next
This tag contains habanalabs driver changes for v6.7.
The notable changes are:
- uAPI changes:
- Expose tsc clock sampling to better sync clock information in profiler.
- Enhance engine error reporting in the info ioctl.
- Block access to the eventfd operations through the control device.
- Disable the option of the user to register multiple times with the same
offset for timestamp dump by the driver. If a user wants to use the same
offset in the timestamp buffer for different interrupt, it needs to first
de-register the offset.
- When exporting dma-buf (for p2p), force the user to specify size/offset
in multiples of PAGE_SIZE. This is instead of the driver doing the
rounding to PAGE_SIZE, which has caused the driver to map more memory
than was intended by the user.
- New features and improvements:
- Complete the move of the driver to the accel subsystem by removing the
custom habanalabs class and major and registering to accel subsystem.
- Move the firmware interface files to include/linux/habanalabs. This is
a pre-requisite for upstreaming the NIC drivers of Gaudi (as they need to
include those files).
- Perform device hard-reset upon PCIe AXI drain event to prevent the failure
from cascading to different IP blocks in the SoC. In secured environments,
this is done automatically by the firmware.
- Print device name when it is removed for better debuggability.
- Add support for trace of dma map sgtable operations.
- Optimize handling of user interrupts by splitting the interrupts to two
lists. One list for fast handling and second list for handling with
timestamp recording, which is slower.
- Prevent double device hard-reset due to 2 adjacent H/W events.
- Set device status 'malfunction' while in rmmod.
- Firmware related fixes:
- Extend preboot timeout because preboot loading might take longer than
expected in certain cases.
- Add a protection mechanism for the Event Queue. In case it is full, the
firmware will be able to notify about it through a dedicated interrupt.
- Perform device hard-reset in case scrubbing of memory has failed.
- Bug fixes and code cleanups:
- Small fixes of dma-buf handling in Gaudi2, such as handling an offset != 0,
using the correct exported size, creation of sg table.
- Fix spmu mask creation.
- Fix bug in wait for cs completion for decoder workloads.
- Cleanup Greco name from documentation.
- Fix bug in recording timestamp during cs completion interrupt handling.
- Fix CoreSight ETF configuration and flush logic.
- Fix small bug in hpriv_list handling (the list that contains the private
data per process that opens our device).

In an MST topology the DSC capabilities are specific to each connector,

branch device between the source and the sink in case this branch device
does the decompression. Accordingly each connector needs to cache its
own DSC DPCD and FEC capabilities, along with the AUX device through
which the decompression can be enabled. This patch prepares for that by
storing the capabilities and the DSC AUX device in the connector, for
now these just matching the version stored in intel_dp. The follow-up

of intel_dp, after which the intel_dp copies are removed.

PSP OS updates the version information in register. On APUs with PSPv13,
PSP OS will already be loaded with SBIOS. Hence use the version register
instead of using information in driver binary header.

drm/amd/display: add missing NULL check for DML2
Recently, the driver introduce DML2 for future ASIC support.
But, some ASIC's hubbub pointer is null before calling.
It cause the below null pointer issue, so add null check to fix it.

drm/amd/display: make dc_set_power_state() return type `void` again
As dc_set_power_state() no longer allocates memory, it's not necessary
to have return types and check return code as it can't fail anymore.
Change it back to `void`.

drm/amd/display: Destroy DC context while keeping DML and DML2
If there is memory pressure at suspend time then dynamically
allocating a large structure as part of DC suspend code will
fail.
Instead re-use the same structures and clear all members except
those that should be maintained.

drm_atomic_helper_suspend() can return PTR_ERR(), in which case the

drm/amd: Split up UVD suspend into prepare and suspend steps
amdgpu_uvd_suspend() allocates memory and copies objects into that
allocated memory. This fails under memory pressure. Instead move
majority of this code into a prepare step when swap can still be
allocated.

drm/amd: Add concept of running prepare_suspend() sequence for IP blocks
If any IP blocks allocate memory during their hw_fini() sequence
this can cause the suspend to fail under memory pressure. Introduce
a new phase that IP blocks can use to allocate memory before suspend
starts so that it can potentially be evicted into swap instead.

drm/amd: Evict resources during PM ops prepare() callback
Linux PM core has a prepare() callback run before suspend.
If the system is under high memory pressure, the resources may need
to be evicted into swap instead. If the storage backing for swap
is offlined during the suspend() step then such a call may fail.
So move this step into prepare() to move evict majority of
resources and update all non-pmops callers to call the same callback.
