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.

Note: The default poll method in the rasdaemon to receive the trace events
didn't work in the QEMU. 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) {
...
