Description

Over multiple mainline iterations, a new CPUID API is slowly getting in shape for both drivers and internal x86 architecture code.

This talk will show that new API, plus its benefits for call-sites.

The API's interaction with the existing X86_FEATURE mechanisms will be covered at the second half of the talk.
