Subject: [PATCH V0 04/21] accel/amdxdna: Upgrade firmware version to 6.0
Date: Fri, 25 Sep 2026 18:34:31 -0700	[thread overview]
Message-ID: <20260926013448.3840921-5-yidong.zhang@amd.com> (raw)
In-Reply-To: <20260926013448.3840921-1-yidong.zhang@amd.com>

Upgrade firmware interface version to 6.0. Update host queue layout,
opcode definitions, and context creation/destruction request structures.
Parse priority band and PASID for hardware context creation.

Note on host queue layout and version validation:
The host queue header layout moves write_index from offset 16 to offset 64
and data_address from offset 24 to offset 120. Protocol compatibility for
this queue layout is validated against the CERT firmware protocol version
(host_queue_major/minor via aie_check_cert_protocol()), which was
introduced in the preceding patch ("accel/amdxdna: Add CERT firmware
version support").
