IsTraceFSAvailable returns nil if a tracefs or debugfs supporting KProbes is available at the well-known paths.

IsTraceFSAvailableAt returns nil if the path passed is a mounted tracefs or debugfs that supports KProbes.

NewCPUSetFromExpression creates a new CPUSet from a range expression.

NewCPUSetFromFile creates a new CPUSet from the contents of a file.

NewDumpDecoder returns a new decoder that will dump all the arguments as a byte slice.

WithBufferSize configures the capacity of the channel used to pass tracing events (PerfChannel.C()).

WithErrBufferSize configures the capacity of the channel used to pass errors.

WithLostBufferSize configures the capacity of the channel used to pass lost event notifications (PerfChannel.LostC()).

WithPollTimeout configures for how long the reader thread can block waiting for events.

WithRingSizeExponent configures the size, in pages, of the ringbuffers used by the kernel to pass events to userspace.
