[PATCH V1 0/6] SR-IOV Virtual Function support for AIE4 platform

[Lizhi Hou]

This series extends amdxdna with initial support for AIE4 Virtual Functions
and the user-visible execution path.

Move message buffer allocation and device metadata collection to aie.c,
allowing both AIE2 and AIE4 devices to reuse common code.

Testing:
  PF + VF: Probe AIE4 PF, enable SR-IOV, bind VF devices, and run
  end-to-end workloads from a userspace application.

  Regression: Validate existing AIE2 regression tests.

David Zhang (5):
  accel/amdxdna: Add initial support for AIE4 VF
  accel/amdxdna: Init AIE4 device partition
  accel/amdxdna: Add AIE4 VF hardware context create and destroy
  accel/amdxdna: Add command doorbell and wait support
  accel/amdxdna: Add AIE4 metadata query support

Nishad Saraf (1):
  accel/amdxdna: Add AIE4 work buffer initialization
