pcm

Change notes:

• Dockerfile bump to Fedora 33
• fix InfluxDB version
• update documentation
• address Fedora rpm packaging issues

Change notes:
• Add Comet Lake support
• Add Tiger Lake support
• Add support for additional Icelake cpu model
• Support Linux resctrl driver for RDT Metrics (see ENVVAR_README.md)
• Improve robustness in handling rare core event overflows
• A few fixes for c_example
• Support using Linux perf API for core PMU for systems with offlined cores

Change log:

• Support Comet Lake (addresses https://github.com/opcm/pcm/issues/249)
• Add -i parameter to more tools (addresses https://github.com/opcm/pcm/issues/243)

Change log:

• support select metrics in virtual machines with vPMU support (e.g. AWS virtualized instances with arch_perfmon flag). Screenshot of grafana dashboard with PCM data from a c5.9xlarge virtualized AWS instance
• pcm-iio: fix VT-d events on SKX

Change log:

• pcm-memory: make -pmm/-pmem the default option on systems with PMM/PMem support
• pcm-tsx: update events for ICL and SKL, allow collection of up to 8 events
• pcm-raw: support fixed PMU counters
• fix UBOX MSR addresses for Jaketown/Ivytown

• support Icelake client CPUs
• new pcm-raw utility: to program arbitrary core and uncore events by specifying raw register event ID encoding
• pcm-memory: support -all option to show channels event if they do not have any traffic (inactive memory channels)
• pcm-memory: csv output for Near Memory hit rate (in PMem Memory Mode)
• pcm-memory: show memory channels with PMM but w/o DRAM DIMMs
• unfreeze counters using global uncore counter control register during uncore PMU initialization (some other tools freeze using global control before exit)

• support Cooper Lake processors
• allow running PCM Docker container without privileged settings
• added docker-compose file
• inroduced pcm name space to avoid name collisions
• better interoperability with pqos RDT utility
• allow compilation with older g++4.8 compiler

• new pcm-sensor-server: metric exporter in json and prometheus formats (over http(s))
• added dockerfile for pcm-sensor-server
• grafana dashboard generator
• new pcm-mmio utility: read/write memory mapped registers

pcm-latency : monitor L1 cache miss and DDR/PMM memory latency
