Module Name: src
Committed By: jmcneill
Date: Sat Jan 16 15:34:37 UTC 2021
Modified Files:
src/usr.sbin/cpuctl/arch: aarch64.c
Log Message:
ID_AA64PFR0_EL1.GIC=0 means that the CPU interface system registers are
not implemented. This does not necessarily mean that there is no GIC in the
system, as GICv2 uses MMIO instead of system registers for the CPU
interface.
While here, add description for GIC=3, which means that the v4.1 system
register interface is supported.
