This driver exports:

- formats, used by perf user space and other tools to configure events
- events, used by perf user space and other tools to create events
- symbolically, e.g.:
+ symbolically, e.g.::
+
perf stat -a -e mac_iod0_mac0_ch0/event=0x21/ ls
perf stat -a -e pci_iod0_pci0/event=0x24/ ls
+
- cpumask, used by perf user space and other tools to know on which CPUs
to open the events
This driver supports the following events for MAC:
+
- cycles
This event counts MAC cycles at MAC frequency.
- read-count
perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls
And, this driver supports the following events for PCI:
+
- pci-port0-cycles
This event counts PCI cycles at PCI frequency in port0.
- pci-port0-read-count
