49 NVLink-C2C0 PMU
50 --------------------
52 The NVLink-C2C0 PMU monitors incoming traffic from a GPU/CPU connected with
53 NVLink-C2C (Chip-2-Chip) interconnect. The type of traffic captured by this PMU
63 PCIE device of the remote SoC.

75 perf stat -a -e nvidia_nvlink_c2c0_pmu_0/event=0x0/
77 * Count event id 0x0 from the GPU/CPU connected with socket 1::

89 The NVLink-C2C has two ports that can be connected to one GPU (occupying both
90 ports) or to two GPUs (one GPU per port). The user can use "port" bitmap
91 parameter to select the port(s) to monitor. Each bit represents the port number,
92 e.g. "port=0x1" corresponds to port 0 and "port=0x3" is for port 0 and 1. The
95 Example for port filtering:

105 NVLink-C2C1 PMU
106 -------------------
108 The NVLink-C2C1 PMU monitors incoming traffic from a GPU connected with
109 NVLink-C2C (Chip-2-Chip) interconnect. This PMU captures untranslated GPU
110 traffic, in contrast with NvLink-C2C0 PMU that captures ATS translated traffic.

135 The NVLink-C2C has two ports that can be connected to one GPU (occupying both

154 The CNVLink PMU monitors traffic from GPU and PCIE device on remote sockets
155 to local memory. For PCIE traffic, this PMU captures read and relaxed ordered

193 PCIE PMU
194 ------------
196 The PCIE PMU monitors all read/write traffic from PCIE root ports to
201 see /sys/bus/event_source/devices/nvidia_pcie_pmu_<socket-id>.
203 Each SoC socket can support multiple root ports. The user can use
204 "root_port" bitmap parameter to select the port(s) to monitor, i.e.
205 "root_port=0xF" corresponds to root port 0 to 3. The PMU will monitor all root
