Subject: [PATCH] tracing: Include PPIN in mce_record tracepoint
Date: Tue, 23 Jan 2024 17:51:50 -0600 [thread overview]
Message-ID: <20240123235150.3744089-1-avadhut.naik@amd.com> (raw)
Machine Check Error information from struct mce is exported to userspace
through the mce_record tracepoint.
Currently, however, the PPIN (Protected Processor Inventory Number) field
of struct mce is not exported through the tracepoint.
Export PPIN through the tracepoint as it may provide useful information
for debug and analysis.
