This patch adds support for performance reporting private feature
for FPGA Management Engine (FME). Now it supports several different
performance counters, including 'basic', 'cache', 'fabric', 'vtd'
and 'vtd_sip'. It allows user to use standard linux tools to access
these performance counters.
e.g. List all events by "perf list"
perf list | grep fme
dfl_fme0/cache_read_hit/ [Kernel PMU event]
dfl_fme0/cache_read_miss/ [Kernel PMU event]
...
dfl_fme0/fab_mmio_read/ [Kernel PMU event]
dfl_fme0/fab_mmio_write/ [Kernel PMU event]
...
dfl_fme0/fab_port_mmio_read,portid=?/ [Kernel PMU event]
dfl_fme0/fab_port_mmio_write,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_port_devtlb_1g_fill,portid=?/ [Kernel PMU event]
dfl_fme0/vtd_port_devtlb_2m_fill,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_sip_iotlb_1g_hit/ [Kernel PMU event]
dfl_fme0/vtd_sip_iotlb_1g_miss/ [Kernel PMU event]
...
dfl_fme0/clock [Kernel PMU event]
...
e.g. check increased counter value after run one application using
"perf stat" command.
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_mmio_write/ ./test
Performance counter stats for './test':
1 dfl_fme0/fab_mmio_read/
2 dfl_fme0/fab_mmio_write/
1.009496520 seconds time elapsed
Please note that fabric counters support both fab_* and fab_port_*, but
actually they are sharing one set of performance counters in hardware.
If user wants to monitor overall data events on fab_* then fab_port_*
can't be supported at the same time, see example below:
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_port_mmio_write,portid=0/
Performance counter stats for 'system wide':
0 dfl_fme0/fab_mmio_read/
<not supported> dfl_fme0/fab_port_mmio_write,portid=0/
