Subject: [PATCH v2 0/2] fsi and hwmon (occ): Prevent occasional checksum failures
Date: Tue, 26 Apr 2022 10:49:54 -0500 [thread overview]
Message-ID: <20220426154956.27205-1-eajames@linux.ibm.com> (raw)
Due to the OCC communication design with a shared SRAM area,
checkum errors are expected due to corrupted buffer from OCC
communications with other system components. Therefore, use a
unique errno for checksum failures and retry the command twice
in that case.
Changes since v1:
- Refactor the retry loop
Eddie James (2):
fsi: occ: Fix checksum failure mode
hwmon (occ): Retry for checksum failure
