[PATCH v1 0/5] drm/xe: add VM_BIND DECOMPRESS support and on‑demand decompression

[Nitin Gote]

This series implements VM_BIND decompression support in the XE driver
and adds on‑demand decompression at VMA pagefault time.

Tested with https://patchwork.freedesktop.org/series/154711/
which validates basic VM_BIND DECOMPRESS behavior for both
regular and FAULT_MODE VMs.

Nitin Gote (5):
  drm/xe: add VM_BIND DECOMPRESS uapi flag
  drm/xe: add xe_migrate_resolve wrapper and is_vram_resolve support
  drm/xe: add drm_exec helper to atomically lock VM (+ optional BO) with
    BOOKKEEP retry
  drm/xe: implement VM_BIND decompression in vm_bind_ioctl
  drm/xe: perform on-demand decompression on VMA pagefaults

[PATCH v1 1/5] drm/xe: add VM_BIND DECOMPRESS uapi flag

[Nitin Gote]

Add DRM_XE_VM_BIND_FLAG_DECOMPRESS to the userspace API so callers
can request GPU-side decompression on VM_BIND.

This flag is used by subsequent driver changes to trigger scheduling of
GPU work that resolves compressed VRAM pages into an uncompressed PAT
VM mapping.

[PATCH v1 2/5] drm/xe: add xe_migrate_resolve wrapper and is_vram_resolve support

[Nitin Gote]

Introduce an internal __xe_migrate_copy(..., is_vram_resolve) path and
expose a small wrapper xe_migrate_resolve() that calls it with
is_vram_resolve=true.

For resolve/decompression operations we must ensure the copy code uses
the compression PAT index when appropriate; this change centralizes that
behavior and allows callers to schedule a resolve (decompress) operation
via the migrate API.

[PATCH v1 3/5] drm/xe: add drm_exec helper to atomically lock VM (+ optional BO) with BOOKKEEP retry

[Nitin Gote]

Add xe_vm_exec_lock_vm_and_bo(), a drm_exec-based helper that atomically
acquires the VM reservation and an optional BO reservation. When requested
(wait_bookkeep) the helper verifies DMA_RESV_USAGE_BOOKKEEP is clear and,
if not, releases the exec locks, waits outside the reservation and retries.

This centralises the drm_exec + BOOKKEEP wait/retry logic used by vm_bind
paths, avoiding duplicated code and preventing sleeps while holding resv
locks. Caller must call drm_exec_fini(exec) on success and must not
re-acquire vm->lock while exec holds the reservations.

[PATCH v1 4/5] drm/xe: implement VM_BIND decompression in vm_bind_ioctl

[Nitin Gote]

Implement handling of VM_BIND(..., DECOMPRESS) in xe_vm_bind_ioctl.

- Validate decompression preconditions (VRAM buffer, flat CCS support,
  XE2+ hardware, and an uncompressed PAT index).
- Mark the BO with DRM_XE_VM_BIND_FLAG_DECOMPRESS.
- Invalidate any overlapping VMA when required.
- Use helper xe_vm_exec_lock_vm_and_bo(..., wait_bookkeep=true)
  to atomically acquire the VM reservation and optional BO reservation and
  handle BOOKKEEP wait/retry.
  * Drop vm->lock before calling the helper.
  * Do VMA invalidation or schedule the migrate resolve while reservations
    are held.
  * Call drm_exec_fini() to release reservations, then wait on the
    migrate/decompression fence without holding reservations and
    re-acquire vm->lock to continue.
- Defer decompression when the VM is in fault mode.

This schedules an in-place GPU resolve (xe_migrate_resolve) for
decompression and waits for completion before proceeding with the bind.
The change centralises drm_exec + BOOKKEEP retry logic and avoids
sleeping while holding resv locks.

[PATCH v1 5/5] drm/xe: perform on-demand decompression on VMA pagefaults

[Nitin Gote]

When a VMA pagefault occurs and the bound BO has the DECOMPRESS flag,
schedule a resolve (xe_migrate_resolve) to perform per-page decompression
before binding the VMA to the faulting GT.

Behavior:
 - schedule xe_migrate_resolve() while holding appropriate reservations,
 - wait on the returned fence, then clear the BO's DECOMPRESS flag
   on success,
 - proceed with the normal rebind path.

This ensures on-demand fault-time decompression works consistently with
the VM_BIND path.

I think this can crash with NPD or other nasties since ttm.resource is 
dynamic state and we need to hold dma-resv lock if touching it (only 
held below AFAICT). Also memory can get evicted or can be deferred until 
first use, so this would return an error for those cases?

XE_CACHE_NONE_COMPRESSION is one of many possible compression enabled 
indexes. Why do we only check this one? Also for all of these uAPI 
sanity checks I think it's best practice to use XE_IOCTL_DBG.

Thank you for pointing this out. I will move it under drm-resv lock, like after xe_vm_exec_lock_vm_and_bo() call.

Agree, I will check with XE_IOCTL_DBG and update in next version

This is not the correct check. What we want is to ensure is_decompress
can only be set on DRM_XE_VM_BIND_OP_MAP ops. So the if statement to
modify is:

Old code:
3567                     XE_IOCTL_DBG(xe, op != DRM_XE_VM_BIND_OP_MAP &&
3568                                  (is_null || is_cpu_addr_mirror)) ||

New code:
3567                     XE_IOCTL_DBG(xe, op != DRM_XE_VM_BIND_OP_MAP &&
3568                                  (is_decompress || is_null || is_cpu_addr_mirror)) ||

This is way to much code and not correct place in bind pipeline to do this.

I think a single function call in vma_lock_and_validate is issue the
decompress what we want.

I'd make this xe_bo.c layer function which calls in xe_migrate.c layer
to issue the decompress and installs returned fence into the BOs or VMs
dma-resv kernel slot. This ensures subsequent bind operations have the
correct dependencies.

The above validation makes sense here as the BO is required.

The above checks likely can be moved to vm_bind_ioctl_check_args they only
rely on Xe and VM being present which vm_bind_ioctl_check_args has.

Everything between my last comment and above should be in moved to a new
function called in vma_lock_and_validate. Also as noted, no need to
directly wait on the fence, just install it into either VM's or BO's
dma-resv KERNEL slot - that is what xe_bo_validate does too.

Why special case decompress for page faults? I don't really understand
the reasoning. Beyond that, there are quite of few problematic issues
with the way this is implemented but I don't see the point in going over
until I understand why this special cased (i.e., why don't you just do
this in the bind IOCTL?).

You need kernel doc explaining what this does and the semantics (i.e.,
where this flag is valid).
