Subject: [PATCH v2 1/2] drm/xe: move page fault descriptors to uc types file
Date: Tue, 18 Feb 2025 13:27:01 +0200	[thread overview]
Message-ID: <20250218112702.262780-1-dafna.hirschfeld@intel.com> (raw)

Future asic will have different firmware to handle page faults.
Meanwhile future asic will have the same pf descriptor as guc
so we should move the descriptors to xe_uc_fw_types.c

Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@intel.com>

changes since v1: same patch-set but rebased correctly.
