Wed Mar 3 2021 Stephanie Brink brink2@llnl.gov v0.4.0

Add support for ARM Juno architecture
Add top-level API to query available frequencies, add support for Intel and ARM
Add JANSSON-C dependency
Introduce JSON API to return monitoring data into a structure
Update variorum to build and run with both msr-safe < v1.5 (msr_whitelist) msr-safe >= v1.5 (msr_allowlist)
Add best effort node power cap support for Intel Broadwell and IBM
Build option to enable all warnings, cleanup compiler warnings
Default build type switched from Release to RelWithDebInfo
Consistent formatting for verbose printouts across architectures
Update year in license headers
Update docs throughout: JSON API, best effort power cap, architectures supported, add sample output to examples
Rename set functions to cap throughout top-level API (and internally in architecture-level functions) to clarify that the setting is an upper bound; instantaneous reads on these metrics may be at or below the value

Setup unit test infrastructure, test on gitlab to leverage msr-safe and OPAL access
Update return code for top-level variorum APIs from -1 to 0, enables us to run unit tests on any architecture
Fix poll_power and monitoring segfaults
Start adding python utilities to verify system environments (i.e. msr-safe, OPAL)
Rename variorum_set_topology to variorum_get_topology
Rename variorum examples
Add example integrations with cmake/make-build systems and c/cpp/fortran codes, use these in CI workflow to test install
Use spack mirrors in CI workflow to avoid failed fetch commands
New mailing lists: variorum-users and variorum-maintainers
Nvidia port: use node topology to map GPU to sockets
Fix for building variorum as static library
Add source code (c/cpp/h/python) format check to CI workflow
Add Contributor Covenant Code of Conduct

Initial release to https://github.com/llnl/variorum!
Includes support for Intel platform -- Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake, and Kaby Lake architectures
Includes support for IBM platform -- Power9 architecture
Add powmon command line sample for monitoring performance counters during application execution
Initial RTD at https://variorum.readthedocs.io
Rename libvariorum to variorum
Bug fix for computing power from energy on Intel
Add developer docs for supporting new platforms
Add info on IBM sensors, OCC, and power shifting ratio
Rename front-facing APIs from print_() to print_verbose_() and dump_() to print_()

Initial release to libvariorum repo on internal Bitbucket.
Base Sphinx documentation taken from SDAV Alpine project. Still has some legacy info as an example..
Use Breathe to interpret Doxygen source code comments for documentation on Sphinx webpage.
Download and build hwloc dependency.
Include googletest in libvariorum source code and build dependency.
Include a couple googletests checking the presence, permissions, and validity of the msr and msr-safe drivers and the msr whitelist.
Include a host configuration file for LLNL's catalyst system using Intel's compilers to generate a CMakeCache.txt.
Add support for the following features: print/dump_power(), print/dump_counters(), print/dump_thermals(), print/dump_package_frequency(), print/dump_power_limits(), print_topology(), print_features().
Write examples for the above set of features.
Add offset lists for Ivy Bridge, Broadwell, and Kaby Lake.
