[PATCH v3 1/2] perf tools: add 'perf irq' to measure the hardware interrupts

2021-01-15 Thread Bixuan Cui
Add 'perf irq' to trace/measure the hardware interrupts. Now three functions are provided: 1. 'perf irq record ' to record the irq handler events. 2. 'perf irq script' to see a detailed trace of the workload that was recorded. 3. 'perf irq report' to calculate the time consumed by each
