[ hwpmc_mod.c:1.14,1.15 ]
- Print PMC capabilities at module load time.
- Return EOPNOTSUPP instead of EINVAL if a PMC allocation request
specifies a PMC capability (e.g., sampling) that is not supported
by hardware. Return EINVAL early if the PMC class passed in is
not recognized.
[ hwpmc_x86.c:1.3 ]
- On x86 processors, turn off 'INTERRUPT' capabilities on PMCs
if the CPU does not have its local APIC enabled.
