Subject: [PATCH v3 1/3] drm/imagination: Add missing rogue context reset reasons
Date: Mon, 23 Mar 2026 20:31:28 +0200 [thread overview]
Message-ID: <20260323-b4-firmware-context-reset-notification-handling-v3-1-1a66049a9a65@imgtec.com> (raw)
In-Reply-To: <20260323-b4-firmware-context-reset-notification-handling-v3-0-1a66049a9a65@imgtec.com>
Update the context reset reason enum with the missing reset reasons in
the 6-11 value gap:
- CDM Mission/safety checksum mismatch;
- TRP checksum mismatch;
- GPU ECC error (corrected, OK);
- GPU ECC error (uncorrected, HWR);
- FW ECC error (corrected, OK);
- FW ECC error (uncorrected, ERR);
