I am planning to evolve the performance tools that I had written for FreeBSD in 2005.

The goals for the revised implementation are:

To support for modern hardware performance monitoring features (this needs the programming API to be changed).
To improve the testability of the project’s code.
To improve its portability to other operating system kernels.
To improve its interoperability with existing visualization tools.
To use an ‘RFC’-like or ‘PEP’-like process to guide the evolution of the tools.
To offer users and implementors appropriately scaffolded documentation (see Cameron Shorter 2018).
