Excuse me, what's profile used here? I can't find the definition in Documentation/dev-tools/kselftest.rst.
Ah, sorry, I added timestamping output as a local patch for NIPA.
To be clear the profile=1 enables the timestamps from my local patch
Random example:
TAP version 13 1..1 # overriding timeout to 7200 # selftests: net: amt.sh # 13.15 [+13.15] TEST: amt discovery [ OK ] # 16.27 [+3.12] TEST: IPv4 amt multicast forwarding [ OK ] # 19.14 [+2.86] TEST: IPv6 amt multicast forwarding [ OK ] # 670.88 [+651.74] TEST: IPv4 amt traffic forwarding torture [ OK ] # 1203.28 [+532.40] TEST: IPv6 amt traffic forwarding torture [ OK ] ok 1 selftests: net: amt.sh
It's not great, makes the lines longer and misaligned. But it's helpful for debugging slow tests.
