Hi everyone,
does the linux kernel process scheduler tackle priority inversion problems? - one good solution may be to randomly boost the priority of ready processes, such that the low-priority process will release a contended resource faster
I suppose, if there were a significant proportion of uni-processor linux installations, it may be worth implementing a ceiling-priority scheduler. This would negate the need for any syncronisation/lock primitives, also eliminating deadlocks entirely. The VxWorks OS implements such a scheme, IIRC.
For the SMP scheduler, is priority inheritance used?
