Now that I'm looking at this with fresher eyes, I think below form would
be much better:
cpuid_eax_native()
cpuid_ebx_native()
cpuid_ecx_native()
cpuid_edx_native()
So that it aligns with:
cpuid_eax()
cpuid_ebx()
cpuid_ecx()
cpuid_edx()
at the rest of the <cpuid/api.h> header. Thus the diff becomes:
- cpuid_1_eax = native_cpuid_eax(1);
+ cpuid_1_eax = cpuid_eax_native(1);
- if (native_cpuid_ecx(1) & BIT(31))
+ if (cpuid_ecx_native(1) & BIT(31))
But I'll wait for review feedback before rolling a v2. Maybe people want
to keep having "native_" at the start, instead of forcing a strict
"cpuid_" namespace.
(With "CPUID refactoring" hat on, and as the above mini diff shows, I
honestly think forcing a "cpuid_" namespace, even on native OPs, is much
cleaner.)
Thanks,
