%c%RAPL PAPI Interface
|
|
|
|
* Access to RAPL data requires reading
|
|
a CPU MSR register.
|
|
This requires OS support
|
|
|
|
* Linux currently has no driver and
|
|
likely won't for the near future
|
|
|
|
* Linux does support an 'MSR' driver.
|
|
Given proper read permissions, MSRs
|
|
can be accessed via /dev/cpu/*/msr
|
|
|
|
* PAPI uses the 'MSR' driver to gather
|
|
RAPL values
