[PATCH V2 2/4] rasdaemon: Add support for the CXL poison events

shiju.jose
2023-01-24T16:58:08Z

From: Shiju Jose <shiju.jose@huawei.com>

Add support to log and record the CXL poison events.

The corresponding Kernel patches here:
https://lore.kernel.org/linux-cxl/de11785ff05844299b40b100f8e0f56c7eef7f08.1674070170.git.alison.schofield@intel.com/

Presently RFC draft version for logging, could be extended for the policy
based recovery action for the frequent poison events depending on the above
kernel patches.
