Subject: [LTP] sched_rr_get_interval01 depends on particular CONFIG_HZ value
Date: Tue, 18 Jul 2023 13:40:27 +0200 [thread overview]
Message-ID: <20230718114027.GA1172148@pevik> (raw)
Hi,
sched_rr_get_interval01.c depends on particular CONFIG_HZ value.
Recent change in openSUSE kernel from the default 250 to 300 breaks it:
sched_rr_get_interval01.c:57: TPASS: sched_rr_get_interval() passed
sched_rr_get_interval01.c:64: TPASS: Time quantum 0s 99999990ns
sched_rr_get_interval01.c:72: TFAIL: /proc/sys/kernel/sched_rr_timeslice_ms != 100 got 90
sched_rr_get_interval01.c:57: TPASS: sched_rr_get_interval() passed
sched_rr_get_interval01.c:64: TPASS: Time quantum 0s 99999990ns
sched_rr_get_interval01.c:72: TFAIL: /proc/sys/kernel/sched_rr_timeslice_ms != 100 got 90
According to kernel/Kconfig.hz CONFIG_HZ can have various values (100, 250, 300,
1000). Should we adapt the test to expect any of these? Or should we require
kernel config to read CONFIG_HZ value and check for correct value?
Kind regards,
Petr
