1 ## @file 2 # Instance of Timer Library only using CPU resources. 3 # 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. 12 # 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. 15 # 16 # Copyright (c) 2010 - 2015, Intel Corporation.
