2. condense metric table in html
3. remove rounding for system TSC calculation
4. add instruction mixes

1.3.4

• remove readme from perfspect.tgz
• move cycles to its own group when in a VM due to it being hidden in most CSP's
• filter out MSR required events when inside VM

1.3.3

updated html report to:

• x-axis now contains actual timestamps
• diffs are now calculated more intuitively with coloring for up and now
• diff in separate column
• TMA and PSI both under bottlenecks tab
• rounded values
• table now fits content instead of 100%
• disclaimer explaining all the periods in TMA metric names
• help info now behind help icon

1.3.2

• added per transaction flag to postprocess
• added diff utility to html report

1.3.1

• update tma support detection to not require msr kernel module
• update html report
  • add metadata
  • add all metric averages
  • add metric descriptions

1.3.0

Breaking change

• changed --thread flag to --cpu to align with Linux norms

Non-breaking changes

• added more metrics to all platforms:
  • metric_locks retired per instr
  • metric_% Uops delivered from decoded Icache (DSB)
  • metric_% Uops delivered from legacy decode pipeline (MITE)
• dynamically detect vPMU driver support for TMA fixed events
• refactored perf-postprocess for readability
• fixed some typos

1.2.14

1. added PSI metrics
2. fix vm check

1.2.13

1. bug fix cstate events when hyperthreading off
2. add metadata to logs of perf-collect
3. better handle short collection periods

1.2.12

1. fixing bug with html report not getting read as utf-8
2. adding TMA version to readme

1.2.11

New in v1.2.11:

• updated CLX, SKX, BDX metrics and events to latest perfmon
• improved cid mode (auto-selects 5 containers with highest cpu util)
• optimized postprocessing speed
• changed output interval to 5 seconds and multiplexing to 125ms (eliminates perf overhead)
