Subject: [PATCH v3 3/3] ARM: dts: aspeed: Update Odyssey SBEFIFO compatible strings
Date: Fri, 19 Apr 2024 16:11:43 -0500 [thread overview]
Message-ID: <20240419211143.1039868-4-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240419211143.1039868-1-eajames@linux.ibm.com>
A new type of SBE, found on the Odyssey chip, will return any async FFDC in
the next transaction, so collecting the FFDC is unnecessary and results in
unexpected behavior. This difference in behavior between the Odyssey SBE
and the POWER9/10 SBEs wasn't apparent when support for the Odyssey was
added. To fix the unexpected behavior, set the new compatible string for
Odyssey SBEFIFOs so that they don't collect async FFDC.
