After removal of "erms" in microarchitectures.json , znver3 detection was successful on following OS SLES 15,CentOS 8.2.2004 and CentOS 8.3.2011
@amd-toolchain-support @GaneshPrasadMA I was wondering if the CPU flags invpcid
, ospke
and pku
are relevant for binary compatibility between zen versions. I was briefly reading their description here:
invpcid: Invalidate Processor Context ID
pku: Protection Keys for Userspace
ospke: OS Protection Keys Enable
and they don't seem to be directly related to any instruction that can be emitted in the binary. Am I off track here?
Please note that we will check the same and get back to you
Removed entries invpcid,ospke, pku, in znver3 section and created a new pull request https://github.com/archspec/archspec-json/pull/28
