Subject: [PATCH 0/5] Several updates for PTT driver
From: Yicong Yang <yangyicong@...ilicon.com>
This series contains several updates for PTT driver:
- Disable interrupt when trace stops, reverse to what we do in trace start
- Always handle the interrupt in hardirq context
- Optimize the AUX buffer handling to make consumer have more time to process
the data
- Since we're a uncore PMU so block any task attach operation
- Add a dummy pmu::read() callback since the perf core may use
Junhao He (1):
