Message

From: Shiju Jose <[e-mail]>

Log and record the following CXL errors reported through the kernel
trace events. CXL poison errors, CXL AER uncorrectable errors and CXL AER
correctable errors.

Note1: This V3 patch set resend due to email delivery issues to
some of the recipients.


Note2: The default poll and read method in the rasdaemon to receive
the trace events do not work due to a commit in the kernel trace system.
Thus instead used the pthread way for testing the CXL error events.
To do so, please make following change in the ras-events.c
<change start ...>
/* rc = read_ras_event_all_cpus(data, cpus); */
rc = -255;
< ...change end >
/* Poll doesn't work on this kernel. Fallback to pthread way */
if (rc == -255) {
...
