[v14,00/19] Timestamp synchronization of host - guest

Message

Tzvetomir Stoyanov (VMware) Nov. 27, 2019, 2:02 p.m. UTC

Basic infrastructure for host - guest timestamp synchronization and a
POC implementation of PTP-like algorithm. 

Tzvetomir Stoyanov (7):
  trace-cmd: Implement new lib API: tracecmd_local_events_system()
  trace-cmd: Add support for negative time offsets in trace.dat file
  trace-cmd: Add implementations of htonll() and ntohll()
  trace-cmd: Add new library APIs for ftrace instances.
  trace-cmd: Find and store pids of tasks, which run virtual CPUs of
    given VM
  trace-cmd: Implement new API tracecmd_add_option_v()
  trace-cmd: Implement new option in trace.dat file:
    TRACECMD_OPTION_TIME_SHIFT

Tzvetomir Stoyanov (VMware) (12):
  trace-cmd: Add new library API for local CPU count
  trace-cmd: Add new library API for reading ftrace buffers
  trace-cmd:  --del the tracee address map into the guest's trace.dat
    file
  trace-cmd: Add new API to generate a unique ID of the tracing session
  trace-cmd: Store the session tracing ID in the trace.dat file
  trace-cmd: Exchange tracing IDs between host and guest
  trace-cmd: Add guest information in host's trace.dat file
  trace-cmd: Add host trace clock as guest trace argument
  trace-cmd: Refactor few trace-cmd internal functions.
  trace-cmd: Basic infrastructure for host - guest timestamp
    synchronization
  trace-cmd:  [POC] PTP-like algorithm for host - guest timestamp
    synchronization
  trace-cmd: Debug scripts for PTP-like algorithm for host - guest
    timestamp synchronization
