Title:
OpenSSL CPU detection for AMD Ryzen CPUs
Status in openssl package in Ubuntu:
Triaged
Bug description:
It has been brought to my attention that :
"CPUID detection in OpenSSL does not properly detect potential optimizations
for AMD processors."
After further verification on my side :
Extended feature flags were not pulled on AMD processors, as result a
number of extensions were effectively masked on Ryzen CPUs. It should
have been reported for Excavator since it implements AVX2 extension,
but apparently nobody noticed ...
