Updates for v6.17
CI:
- uprev mesa and ci-templates
- use shallow clone to speed up build jobs
- remove sdm845/cheza jobs. These runners are no more (RIP
dear chezas)
- fix runner tag for i915 cml runners
- uprev igt to pull in msm test fixes
Core:
- VM_BIND support!
- single source of truth for UBWC configuration. Adds a global soc
driver for UBWC config which is used from display and GPU. (And
later vidc/camera/etc)
- Decouple ties between GPU and KMS, adding a `separate_gpu_kms`
modparam to allow the GPU and KMS to bind to separate DRM devices.
This should better deal with more exotic SoC configurations where
the number of GPUs is different from number of DPUs. The default
behavior is to still come up as a single unified DRM device to
avoid surprising userspace.
DP:
- major rework of the I/O accessors
DPU:
- use version checks instead of feature bits
- SM8750 support
- set min_prefill_lines for SC8180X
DSI:
- SM8750 support
GPU:
- speedbin support for X1-85
- X1-45 support
MDSS:
- SM8750 support

The vast majority of drivers that use GEM-SHMEM helpers do not use
an s/g table for imported buffers; specifically all drivers that use
DRM_GEM_SHMEM_DRIVER_OPS. Therefore convert the initializer macro
to DRM_GEM_SHMEM_DRIVER_OPS_NO_MAP_SGT and remove the latter. This
helps to avoid swiotbl errors, such as seen with some Aspeed systems
ast 0000:07:00.0: swiotlb buffer is full (sz: 3145728 bytes), total 32768 (slots), used 0 (slots)
The error is caused by the system's limited DMA capabilities and can
happen with any GEM-SHMEM-based driver. It results in a performance
penalty.
In the case of vgem and vkms, the devices do not support DMA at all,
which can result in failure to map the buffer object into the kernel's
address space. [1][2] Avoiding the s/g table fixes this problem.
The other drivers based on GEM-SHMEM, imagination, lima, panfrost,
panthor, v3d and virtio, use the s/g table of imported buffers. Neither
driver uses the default initializer, so they won't be affected by
this change.

As discussed a lot in the past, the UBWC config must be coherent across
a number of IP blocks (currently display and GPU, but it also may/will
concern camera/video as the drivers evolve).
So far, we've been trying to keep the values reasonable in each of the
two drivers separately, but it really make sense to do so centrally,
especially given certain fields (e.g. HBB) may need to be gathered
dynamically.
To reduce room for error, move to fetching the config from a central
source, so that the data programmed into the hardware is consistent
across all multimedia blocks that request it.

For UNMAP/REMAP steps we could be needing to lock objects that are not
explicitly listed in the VM_BIND ioctl in order to tear-down unmapped
VAs. These helpers handle locking/preparing the needed objects.
Note that these functions do not strictly require the VM changes to be
applied before the next drm_gpuvm_sm_map_lock()/_unmap_lock() call. In
the case that VM changes from an earlier drm_gpuvm_sm_map()/_unmap()
call result in a differing sequence of steps when the VM changes are
actually applied, it will be the same set of GEM objects involved, so
the locking is still correct.

is safe in the case of overlapping driver VM_BIND ops.

Only sysfb drivers use drm_fb_build_fourcc_list(). Move the function
to sysfb helpers and rename it accordingly. Update drivers and tests.
v3:
- update naming in tests
v2:
- select DRM_SYSFB_HELPER (kernel test robot)

Export additional helpers from the format-helper library and open-code
drm_fb_blit() in tests. Prepares for the removal of drm_fb_blit(). Only
sysfb drivers use drm_fb_blit(). The function will soon be removed from
format helpers and be refactored within sysfb helpers.

On Xe2+ platforms, media engines are attached to "SCMI" OA media (OAM)
units. One or more SCMI OAM units might be present on a platform. In
addition there is another OAM unit for global events, called
OAM-SAG. Performance metrics for media workloads can be obtained from these
OAM units, similar to OAG.
Expose these OAM units for userspace to use. OAM-SAG is exposed as an OA
unit without any attached engines.
Bspec: 70819, 67103, 63844, 72572, 74476, 61284
v2: Fix xe_gt_WARN_ON in __hwe_oam_unit for < 12.7 platforms
v3: Return XE_OA_UNIT_INVALID for < 12.7 to indicate no OAM units
v4: Move xe_oa_print_oa_units() to separate patch
v5: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG
v6: Introduce DRM_XE_OA_CAPS_OAM
