The layout of bits within the individual tiles
(referred to as sectors in the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro)
changed for 8 and 16-bit surfaces starting in
Blackwell 2 GPUs (With the exception of GB10).
To denote the difference, extend the sector field
in the parametric format modifier definition used
to generate modifier values for NVIDIA hardware.
Without this change, it would be impossible to
differentiate the two layouts based on modifiers,
and as a result software could attempt to share
surfaces directly between pre-GB20x and GB20x
cards, resulting in corruption when the surface
was accessed on one of the GPUs after being
populated with content by the other.
Of note: This change causes the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro to
evaluate its "s" parameter twice, with the side
effects that entails. I surveyed all usage of the
modifier in the kernel and Mesa code, and that
does not appear to be problematic in any current
usage, but I thought it was worth calling out.

The madvise implementation currently resets the SVM madvise if the
underlying CPU map is unmapped. This is in an attempt to mimic the
CPU madvise behaviour. However, it's not clear that this is a desired
behaviour since if the end app user relies on it for malloc()ed
objects or stack objects, it may not work as intended.
Instead of having the autoreset functionality being a direct
application-facing implicit UAPI, make the UMD explicitly choose
this behaviour if it wants to expose it by introducing
DRM_XE_VM_BIND_FLAG_MADVISE_AUTORESET, and add a semantics
description.

Introduce the DRM_IOCTL_XE_VM_QUERY_MEMORY_RANGE_ATTRS ioctl to allow
userspace to query memory attributes of VMAs within a user specified
virtual address range.
Userspace first calls the ioctl with num_mem_ranges = 0,
sizeof_mem_ranges_attr = 0 and vector_of_vma_mem_attr = NULL to retrieve
the number of memory ranges (vmas) and size of each memory range attribute.
Then, it allocates a buffer of that size and calls the ioctl again to fill
the buffer with memory range attributes.
This two-step interface allows userspace to first query the required
buffer size, then retrieve detailed attributes efficiently.

The NPU cores have their own access to the memory bus, and this isn't
cache coherent with the CPUs.

CRIU restore of drm buffer objects requires the ability to create
or import a buffer object with a specific gem handle.
Add new drm ioctl DRM_IOCTL_GEM_CHANGE_HANDLE, which takes
the gem handle of an object and moves that object to a
specified new gem handle.
This ioctl needs to call drm_prime_remove_buf_handle,
but that function acquires the prime lock, which the ioctl
needs to hold for other purposes.
Make drm_prime_remove_buf_handle not acquire the prime lock,
and change its other caller to reflect this.

It's not obvious off-hand which CRTCs will get a page-flip event
when using this flag in an atomic commit, because it's all
implicitly implied based on the contents of the atomic commit.
Document requirements for using this flag and how to request an
event for a CRTC.
Note, because prepare_signaling() runs right after
drm_atomic_set_property() calls, page-flip events are not delivered
for CRTCs pulled in later by DRM core (e.g. on modeset by
drm_atomic_helper_check_modeset()) or the driver (e.g. other CRTCs

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

Add PRR (Partial Resident Region) is a bypass address which make GPU
writes go to /dev/null and reads return zero. This is used to implement
vulkan sparse residency.
To support PRR/NULL mappings, we allocate a page to reserve a physical
address which we know will not be used as part of a GEM object, and
configure the SMMU to use this address for PRR/NULL mappings.

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.

Introduce a new parameter to the DRM_IVPU_CMDQ_CREATE ioctl,
enabling turbo mode for jobs submitted via the command queue.
Turbo mode allows jobs to run at higher frequencies,
potentially improving performance for demanding workloads.
Also adds the IVPU_TEST_MODE_TURBO_DISABLE flag to allow test
mode to explicitly disable turbo mode requested by the application.
The IVPU_TEST_MODE_TURBO mode has been renamed to
IVPU_TEST_MODE_TURBO_ENABLE for clarity and consistency.

Backmerging to forward to v6.16-rc1
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>

Currently, we pick the MMIO offset based on the size of the pgoff_t
type seen by the process that manipulates the FD, such that a 32-bit
process can always map the user MMIO ranges. But this approach doesn't
work well for emulators like FEX, where the emulator is a 64-bit binary
which might be executing 32-bit code. In that case, the kernel thinks
it's the 64-bit process and assumes DRM_PANTHOR_USER_MMIO_OFFSET_64BIT
is in use, but the UMD library expects DRM_PANTHOR_USER_MMIO_OFFSET_32BIT,
because it can't mmap() anything above the pgoff_t size.
In order to solve that, we need a way to explicitly set the user MMIO
offset from the UMD, such that the kernel doesn't have to guess it
from the TIF_32BIT flag set on user thread. We keep the old behavior
if DRM_PANTHOR_SET_USER_MMIO_OFFSET is never called.
Changes in v2:
- Drop the lock/immutable fields and allow SET_USER_MMIO_OFFSET
requests to race with mmap() requests
- Don't do the is_user_mmio_offset test twice in panthor_mmap()
- Improve the uAPI docs
Changes in v3:
- Bump to version 1.5 instead of 1.4 after rebasing
- Add R-bs
- Fix/rephrase comment as suggested by Liviu
