Subject: [PATCH V0 03/21] accel/amdxdna: Add CERT firmware version support
Date: Fri, 25 Sep 2026 18:34:30 -0700 [thread overview]
Message-ID: <20260926013448.3840921-4-yidong.zhang@amd.com> (raw)
In-Reply-To: <20260926013448.3840921-1-yidong.zhang@amd.com>
AIE4 platforms run two separate firmware binaries: NPU firmware for
management and CERT (Column Enternal Run Time) firmware for
handling execution contexts and queues.
Add support to query and validate CERT firmware version:
- Add mailbox opcodes and structs to query NPU firmware version (identify)
and CERT firmware version.
- Unify firmware version storage by using struct
amdxdna_drm_query_firmware_version across the driver.
- Introduce aie_check_cert_protocol() and cert_feature_tbl to validate
CERT firmware host queue protocol compatibility against driver
capabilities.
- Add helper functions amdxdna_get_firmware_version() and
amdxdna_get_aie_version() to share version query handling across
generations.
Note on patch ordering:
Introducing CERT firmware protocol validation prior to the firmware 6.0
upgrade ensures host queue protocol compatibility (host_queue_major/minor)
is validated before the host queue layout restructure, preserving
bisectability.
