◆ status

uint64_t ucode_control::status

Microcode status array physical address.

Definition at line 49 of file ucode.h.

◆ trigger_msr

uint32_t ucode_control::trigger_msr

Microcode load trigger MSR.

Definition at line 51 of file ucode.h.

◆ apic_test

uint32_t ucode_control::apic_test

APIC ID eligibility test bits.

Definition at line 63 of file ucode.h.

◆ ver_clear

uint8_t ucode_control::ver_clear

Microcode version requires manual clear.

Definition at line 65 of file ucode.h.

◆ ver_high

uint8_t ucode_control::ver_high

Microcode version is reported via high dword.
