HI :
Streamline is currently not working properly in my device. there are the following problems:
1. No Perf PMUs detected
[1165.1961225] SETUP: detect(linux/perf/PerfDriverConfiguration.cpp:499): No Perf PMUs detected Could not detect any Perf PMUs in /sys/bus/event_source/devices/ but the system contains recognised CPUs. The system may not support perf hardware counters. Check CONFIG_HW_PERF_EVENTS is set and that the PMU is configured in the target device tree.
I detect the PUM of the device, as follows:
# ls /sys/bus/event_source/devices/ arm_dsu_0 armv8_pmuv3 breakpoint cs_etm llcc-pmu software tracepoint uprobe
and I have enabled CONFIG_HW_PERF_EVENTS.
"/sys/bus/event_source/devices/armv8_cortex_x1" This PMU must exist?
2. no clock and cache related data
I continued to use streamline, I found that there is no data on some of the items shown below.
how should I do it makes streamline? Thank you.
