Patches 1–2 add igt_sysfs_choice and unit tests for parsing and formatting enumerated sysfs values such as sched_priority. Patches 3–4 convert the existing sched_priority helpers in xe_sriov_provisioning into thin wrappers around igt_sysfs_choice. Patch 5 adds a small PF/VF sysfs path helper used by the SR-IOV code. Patch 6 exposes SR-IOV admin sysfs accessors for execution quantum, preemption timeout, scheduling priority, VF stop and restoring defaults, following recent kernel changes: Link: https://lore.kernel.org/intel-xe/20251030222348.186658-1-michal.wajdeczko@intel.com/ Patches 7–10 update the xe_sriov_scheduling and xe_pmu tests to prefer the admin interface, improve cleanup, and add coverage for SR-IOV admin sysfs scheduling attributes in xe_sriov_admin_profile. v2: - Added generic igt_sysfs_choice helper and unit tests. - Reworked sched_priority helpers to use igt_sysfs_choice wrappers. - Introduced igt_sriov_func_str() PF/VF sysfs path helper. - Extended SR-IOV admin helpers with scheduling accessors. - Updated xe_sriov_scheduling and xe_pmu to prefer SR-IOV admin sysfs. - Added xe_sriov_admin_profile tests for admin sysfs scheduling attributes (defaults, write->readback, bulk updates).
