Subject: [PATCH 10/15] x86/zen: Add Zen 3 support
|
|
|
|
Add vendor and family identification as well as the relevant
|
|
events to count per-process memory accesseses and CPU usage
|
|
on AMD Zen 3 family of processors.
|
|
|
|
Key changes include the use of the LsAnyFillsFromSys event
|
|
instead of LsDmndFillsFromSys for counting local and remote
|
|
memory accesses. While LsDmndFillsFromSys covers only demand
|
|
cache fills, LsAnyFillsFromSys covers all cache fills
|
|
including prefetches.
