2 Alibaba's T-Head SoC Uncore Performance Monitoring Unit (PMU)
5 The Yitian 710, custom-built by Alibaba Group's chip development business,
6 T-Head, implements uncore PMU for performance and functional debugging to
9 DDR Sub-System Driveway (DRW) PMU Driver
14 channel is split into two independent sub-channels. The DDR Sub-System Driveway
15 implements separate PMUs for each sub-channel to monitor various performance
20 sub-channels of the same channel in die 0. And the PMU device of die 1 is
23 Each sub-channel has 36 PMU counters in total, which is classified into
26 - Group 0: PMU Cycle Counter. This group has one pair of counters
27   pmu_cycle_cnt_low and pmu_cycle_cnt_high, that is used as the cycle count
30 - Group 1: PMU Bandwidth Counters. This group has 8 counters that are used
35 - Group 2: PMU Retry Counters. This group has 10 counters, that intend to
38 - Group 3: PMU Common Counters. This group has 16 counters, that are used
41 For now, the Driveway PMU driver only uses counters in group 0 and group 3.
