RE: [microblaze-uclinux] thread switching problem (SCHED_RR)
I updated to the latest µLinux kernel from cvs to get John Williams' latest
fixes in arch/microblaze/kernel.
But I still notice this scheduler problem:
- all threads have SCHED_RR
- thread1 has priority 9 and loops infinitely by constantly calling
- as soon as I start a new thread (priority=8) which is just infinitely
doing "while(1);", the timeout in poll() doesn't work anymore and thread1
does not return from poll() although it has a higher priority.
I did the tricky step and extracted the problem stuff from our app and put
it together in a small test user app where you can easily see what is going
on. Is someone interested in trying it and help to fix the
uclinux/microblaze bug? The code also compiles on SuSE-PC-Linux and runs
with SCHED_OTHER there.
