Current code clears event log and ppr log entry after processing it due to hardware errata ([1] erratum #732, #733). We do not have hardware issue on SNP enabled system. When SNP is enabled, the event logs, PPR log and completion wait buffer are read-only to the host (see SNP FW ABI spec [2]). Clearing those entry will result in a kernel #PF for an RMP violation. Hence do not clear event and ppr log entry after processing it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
