- Provide lapic_disable_pmc(), lapic_enable_pmc(), and lapic_reenable_pmc() routines in the local APIC code that the hwpmc(4) driver can use to manage the local APIC PMC interrupt vector. - Do not enable the local APIC PMC interrupt vector by default when HWPMC_HOOKS is enabled. Instead, the hwpmc(4) driver explicitly enables the interrupt when it is succesfully initialized and disables the interrupt when it is unloaded. This avoids enabling the interrupt on unsupported CPUs which may result in spurious NMIs. Reported by: rnoland Reviewed by: jkoshy Approved by: re (kib) MFC after: 2 weeks |
