added SCHED_IDLE support for Cygwin 3.6. It should work.
--------------------------------^^^^^^^^^^^
Cygwin should support it, but I wonder if chrt (in util-linux) has been
updated in light of the change.
Version 3.6 is not a release, so unless you're using a snapshot...
The maintainer can flip Cygwin to test 3.6... and use that to build a test
release of util-linux with Cygwin >= 3.6 as a dependency and make that test
release available.
So you say util-linux only needs to be recompiled?
Yes, otherwise the options related to the newly added SCHED_* defines
have no effect:
util-linux-2.39.3/schedutils/chrt.c:
int main(...)
...
case 'b':
#ifdef SCHED_BATCH
ctl->policy = SCHED_BATCH;
#endif
break;
...
case 'i':
#ifdef SCHED_IDLE
ctl->policy = SCHED_IDLE;
#endif
break;
The 'chrt --help' output is misleading because it always advertises '-b,
--batch', '-i, --idle', ...
