Since commit 4eb0aab6e4434 ("drm/xe/guc: Bump minimum required GuC
version to v70.29.2"), the minimum GuC version required by the driver
is v70.29.2, which should already include everything that we need for
migration.
Remove the version check.

Upcoming changes will allow users to control VF state and obtain its
migration data with a device-level granularity (not tile/gt).
Change the data structures to reflect that and move the GT-level
migration init to happen after device-level init.

In upcoming changes, the number of states will increase as a result of
introducing SAVE and RESTORE states.
This means that using unsigned long as underlying storage won't work on
32-bit architectures, as we'll run out of bits.
Use bitmap instead.

The states will be used by upcoming changes to produce (in case of save)
or consume (in case of resume) the VF migration data.

Add the data structures and handlers that will be used in future

Add debugfs handlers for migration state and handle bitstream
.read()/.write() to convert from bitstream to/from migration data
packets.
As descriptor/trailer are handled at this layer - add handling for both
save and restore side.

with destination.

(mainly when it's in a pre_copy state).

In upcoming changes the cached buffers are going to be used to read data
produced by the GuC. Add a counterpart to flush, which synchronizes the
CPU-side of suballocation with the GPU data and propagate the interface
to GuC Buffer Cache.

An upcoming change will use GuC buffer cache as a place where GuC
migration data will be stored, and the memory requirement for that is
larger than indirect data.
Allow the caller to pass the size based on the intended usecase.

Contiguous PF GGTT VMAs can be scarce after creating VFs.
Increase the GuC buffer cache size to 8M for PF so that we can fit GuC
migration data (which currently maxes out at just over 4M) and use the
cache instead of allocating fresh BOs.

In upcoming changes, SR-IOV VF migration data will be extended beyond
GuC data and exported to userspace using VFIO interface (with a
vendor-specific variant driver) and a device-level debugfs interface.
Remove the GT-level debugfs.

Perhaps this should be retained while we don't have the xe-vfio?

The series adds device-level debugfs, which let's us get the bitstream
with all of the resources (GuC/MMIO/VRAM/GGTT), from all GTs.
I don't think we need a per-GT control for only the GuC migration data.
And if it's needed - it could be extracted from the full bitstream.

In upcoming changes, the GuC VF migration data will be handled as part
of separate SAVE/RESTORE states in VF control state machine.
Remove it from PAUSE state.

In upcoming changes, the GuC VF migration data will be handled as part
of separate SAVE/RESTORE states in VF control state machine.
Now that the data is decoupled from both guc_state debugfs and PAUSE
state, we can safely remove the struct xe_gt_sriov_state_snapshot and
modify the GuC save/restore functions to operate on struct
xe_sriov_migration_data.

In an upcoming change, the VF GGTT migration data will be handled as
part of VF control state machine. Add the necessary helpers to allow the
migration data transfer to/from the HW GGTT resource.

Instead of accessing VF's lmem_obj directly, introduce a helper function
to make the access more convenient.

From: Lukasz Laguna <lukasz.laguna@intel.com>
Introduce a new function to copy data between VRAM and sysmem objects.
The existing xe_migrate_copy() is tailored for eviction and restore
operations, which involves additional logic and operates on entire
objects.
The xe_migrate_vram_copy_chunk() allows copying chunks of data to or
from a dedicated buffer object, which is essential in case of VF
migration.

VF FLR requires additional processing done by PF driver.
The processing is done after FLR is already finished from PCIe
perspective.
In order to avoid a scenario where migration state transitions while
PF processing is still in progress, additional synchronization
point is needed.
Add a helper that will be used as part of VF driver struct
pci_error_handlers .reset_done() callback.

When INTEL_BMG_G21_IDS were added as a subplatform, token concatenation
operator usage was omitted, making INTEL_BMG_IDS not usable with
single-argument macros.
Fix that by adding the missing operator.
