[PATCH v9 5/8] perf tool: Add support for HiSilicon PCIe Tune and Trace device driver

2022-06-06 Thread Yicong Yang via iommu
From: Qi Liu HiSilicon PCIe tune and trace device (PTT) could dynamically tune the PCIe link's events, and trace the TLP headers). This patch add support for PTT device in perf tool, so users could use 'perf record' to get TLP headers trace data. Signed-off-by: Qi Liu Signed-off-by: Yicong
