<pre wrap="" class="moz-quote-pre">Hi,
Based on the discussions around using Netlink for RAS purposes, as
summarized in this blog post [1] by Dave Airlie. I had proposed a series
regarding RAS infrastructure in DRM [2].
I came across your work, which appears to address related areas and I'm
particularly interested in understanding how it aligns with or could be
adapted to the ongoing discussions around leveraging Netlink for RAS.
Could you share your perspective on the potential integration of your
efforts with Netlink? Do you foresee any challenges or opportunities in
aligning with the approach discussed in the above-mentioned blog post
and series?
Looking forward to your insights and any additional thoughts you may
have on this topic.

<pre wrap="" class="moz-quote-pre">This patch series generate RAS CPER records for UE/DE/CE/BP threshold exceed
event. SMU_TYPE_CE banks are combined into 1 CPER entry, they could be CEs or
DEs or both. UEs and BPs are encoded into separate CPER entries.
RAS CPER records for CEs will be generated only after CEs count been queried.
All records are committed to a pure software ring with a limit size, new records
will flush older records when overflow happened. User can access the records by
reading debugfs node, which is read-only.
