# Instance of Timer Library only using CPU resources. | |
# | |
# Timer Library that only uses CPU resources to provide calibrated delays | |
# on IA-32, x64, and IPF. | |
# Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can use this TimerLib | |
# in their initialization without any issues. They only have to be careful in | |
# the implementation of runtime services and SMI handlers. | |
# Because CPU Local APIC and ITC could be programmed by OS, it cannot be | |
# used by SMM drivers and runtime drivers, ACPI timer is recommended for SMM | |
# drivers and runtime drivers. | |
# | |
# Note that for IA-32 and x64, this library only supports xAPIC mode. If x2APIC | |
# support is desired, the SecPeiDxeTimerLibUefiCpu library can be used. | |
