Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

 * xe_gt_sriov_pf_assert_vfid() - warn if &id is not a supported VF number when debugging.
 * @gt: the PF &xe_gt to assert on
 * @vfid: the VF number to assert
 *
 * Assert that &gt belongs to the Physical Function (PF) device and provided &vfid
 * is within a range of supported VF numbers (up to maximum number of VFs that
 * driver can support, including VF0 that represents the PF itself).
 *
 * Note: Effective only on debug builds. See `Xe Asserts`_ for more information.
