commit a78abde220243d6f44a265fe36c49957f6fa9851 upstream.
Parser did not take ':' into account.
Example:
Before:
$ perf record -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.026 MB perf.data ] $ perf inject -i perf.data --vm-time-correlation="dry-run 123" $ perf inject -i perf.data --vm-time-correlation="dry-run 123:456" Failed to parse VM Time Correlation options 0x620 [0x98]: failed to process type: 70 [Invalid argument] $
After:
$ perf inject -i perf.data --vm-time-correlation="dry-run 123:456" $
