Subject: [PATCH v2 0/3] fsi: sbefifo: Prevent async FFDC collection for Odyssey SBEFIFOs
Date: Mon, 15 Apr 2024 10:39:04 -0500 [thread overview]
Message-ID: <20240415153907.10051-1-eajames@linux.ibm.com> (raw)
A new type of SBE on the Odyssey chip will return any async FFDC in the
next transaction, so collecting the FFDC is unnecessary and results in
unexpected behavior. Turn off the async collection for Odyssey SBEFIFOs.
Changes since v1:
- Change "ody" to "odyssey"
- Fix minor issues in binding document
