Direct, unsafe Rust bindings for Linux's perf_event_open system call
This crate exports unsafe Rust wrappers for Linux system calls for accessing
performance monitoring counters and tracing facilities. This includes:
- the processor's own performance monitoring registers
- kernel counters for things like context switches and page faults
- kernel tracepoints, kprobe, and uprobes
- processor tracing facilities like Intel's Branch Trace Store (BTS)
- hardware breakpoints
This crate provides:
- a Rust wrapper the Linux
perf_event_opensystem call - Rust wrappers for the ioctls you can apply to a file descriptor returned by
perf_event_open - bindings for
perf_event_open's associated header files, automatically generated bybindgen
All functions are direct, unsafe wrappers for the underlying calls. They
operate on raw pointers and raw file descriptors.
