[PATCH i-g-t, v4 2/2] drm-uapi/xe: Add test to query HuC firmware version

Francois Dugast francois.dugast at intel.com
Wed Feb 21 13:50:33 UTC 2024


This aligns with kernel commit ("drm/xe: Extend uAPI to query HuC
micro-controler firmware version").

v2:
- Fix printing branch (Francois Dugast)
- Make ENODEV the only accepted error (José Roberto de Souza)

v3: Share code between guc and huc tests (John Harrison)

v4: Better use of asserts to report errors (John Harrison)
