2 # Instance of Timer Library only using CPU resources.
4 # Timer Library that only uses CPU resources to provide calibrated delays
5 # on IA-32, x64, and IPF.
6 # Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can use this TimerLib
7 # in their initialization without any issues. They only have to be careful in
8 # the implementation of runtime services and SMI handlers.
9 # Because CPU Local APIC and ITC could be programmed by OS, it cannot be
10 # used by SMM drivers and runtime drivers, ACPI timer is recommended for SMM
11 # drivers and runtime drivers.
13 # This library differs with the SecPeiDxeTimerLibCpu library in the MdePkg in
14 # that it uses the local APIC library so that it supports x2APIC mode.
