Subject: [PATCH v2 0/5] Several updates for PTT driver
Date: Thu, 14 Sep 2023 19:22:18 +0800 [thread overview]
Message-ID: <20230914112223.27165-1-yangyicong@huawei.com> (raw)
From: Yicong Yang <yangyicong@hisilicon.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
Change since v1:
- Add Jonathan's tag, thanks
