2 HiSilicon SoC uncore Performance Monitoring Unit (PMU)
13 two HHAs (0 - 1) and four DDRCs (0 - 3), respectively.
15 HiSilicon SoC uncore PMU driver
16 -------------------------------
18 Each device PMU has separate registers for event counting, control and
19 interrupt, and the PMU driver shall register perf PMU drivers like L3C,
27 Each L3C, HHA and DDRC is registered as a separate PMU with perf. The PMU
28 name will appear in event listing as hisi_sccl<sccl-id>_module<index-id>.
29 where "sccl-id" is the identifier of the SCCL and "index-id" is the index of
39 ID used to count the uncore PMU event.

56 For HiSilicon uncore PMU v2 whose identifier is 0x30, the topology is the same
57 as PMU v1, but some new functions are added to the hardware.
59 (a) L3C PMU supports filtering by core/thread within the cluster which can be

85 cores. If datasrc_cfg is used in the multi-chips, the datasrc_skt shall be

94 SoC has a unique ID. Each ID is 11bits, include a 6-bit SCCL-ID and 5-bit
95 CCL/ICL-ID. For I/O die, the ICL-ID is followed by:
103 tgtid_cmd & tgtid_msk. A set bit in srcid_msk/tgtid_msk means the PMU will not
