Hi John,
Just fyi, this week Intel announced APX:
https://www.intel.com/content/www/us/en/developer/articles/technical/advanced-performance-extensions-apx.html
It adds new GPRs. To cite from there:
"The new GPRs are XSAVE-enabled, which means that they can be automatically saved and restored by XSAVE/XRSTOR sequences during context switches.
They do not change the size and layout of the XSAVE area as they take up the space left behind by the deprecated Intel® MPX registers."
Not sure if that has any influence on your patch series, I thought it might be interesting for you anyway.
Regards,
Felix
