%description
A whole-system, cross-language profiler for Linux via eBPF.

Core features and strengths
- Implements the experimental OTel profiling signal
- Very low CPU and memory overhead (1% CPU and 250MB memory are our upper
  limits in testing and the agent typically manages to stay way below that)
- Support for native C/C++ executables without the need for DWARF debug
  information (by leveraging .eh_frame data as described in US11604718B1)
- Support profiling of system libraries without frame pointers and without
  debug symbols on the host.
- Support for mixed stacktraces between runtimes - stacktraces go from Kernel
  space through unmodified system libraries all the way into high-level
  languages.
- Support for native code (C/C++, Rust, Zig, Go, etc. without debug symbols on
  host)
- Support for a broad set of HLLs (Hotspot JVM, Python, Ruby, PHP, Node.JS, V8,
  Perl), .NET is in preparation.
- 100% non-intrusive: there's no need to load agents or libraries into the
  processes that are being profiled.
- No need for any reconfiguration, instrumentation or restarts of HLL
  interpreters and VMs: the agent supports unwinding each of the supported
  languages in the default configuration.
- ARM64 support for all unwinders except NodeJS.
- Support for native inline frames, which provide insights into compiler
  optimizations and offer a higher precision of function call chains.
