821 * Notes on internal configuration of ESCR+CCCR tuples
822 *
823 * Since P4 has quite the different architecture of
824 * performance registers in compare with "architectural"
825 * once and we have on 64 bits to keep configuration
826 * of performance event, the following trick is used.
827 *
828 * 1) Since both ESCR and CCCR registers have only low
829 * 32 bits valuable, we pack them into a single 64 bit
830 * configuration. Low 32 bits of such config correspond
831 * to low 32 bits of CCCR register and high 32 bits
832 * correspond to low 32 bits of ESCR register.
833 *
834 * 2) The meaning of every bit of such config field can
835 * be found in Intel SDM but it should be noted that
836 * we "borrow" some reserved bits for own usage and
837 * clean them or set to a proper value when we do
838 * a real write to hardware registers.
839 *
840 * 3) The format of bits of config is the following
841 * and should be either 0 or set to some predefined
842 * values:
843 *
844 * Low 32 bits
845 * -----------
846 * 0-6: P4_PEBS_METRIC enum
847 * 7-11: reserved
848 * 12: reserved (Enable)
849 * 13-15: reserved (ESCR select)
850 * 16-17: Active Thread
851 * 18: Compare
852 * 19: Complement
853 * 20-23: Threshold
854 * 24: Edge
855 * 25: reserved (FORCE_OVF)
856 * 26: reserved (OVF_PMI_T0)
857 * 27: reserved (OVF_PMI_T1)
858 * 28-29: reserved
859 * 30: reserved (Cascade)
860 * 31: reserved (OVF)
861 *
862 * High 32 bits
863 * ------------
864 * 0: reserved (T1_USR)
865 * 1: reserved (T1_OS)
866 * 2: reserved (T0_USR)
867 * 3: reserved (T0_OS)
868 * 4: Tag Enable
869 * 5-8: Tag Value
870 * 9-24: Event Mask (may use P4_ESCR_EMASK_BIT helper)
871 * 25-30: enum P4_EVENTS
872 * 31: reserved (HT thread)
