Change subject: bts: set osmo-bts sched priority to 30
......................................................................
bts: set osmo-bts sched priority to 30
Change the scheduling priority from 10 to 30, as we are currently see
osmo-bts suffering from scheduling latency in jenkins even though we
don't run other jobs at that time:
20250425034138405 DL1C ERROR PC clock skew: elapsed_us=387574, error_us=382959
(scheduler_trx.c:449)
This should fix that the kernel prioritizes other (userspace or kernel)
processes running on the same machine that have a higher priority. We
have seen such an improvement after increasing scheduler priority for
osmo-bts-sysmo too (see I2394e6bbc00a1d47987dbe7b70f4b5cbedf69b10).
Priority 30 is higher than 10. From sched(7):
Processes scheduled under one of the real-time
policies (SCHED_FIFO,
SCHED_RR) have a sched_priority value in the range 1 (low) to 99 (high).
This testsuite currently gets executed through docker-playground and it
fetches this config from osmo-ttcn3-hacks (see
If15461240f3037c142c176fc7da745a1701ae3f8).
