We are pleased to announce the next update to our new preempt-rt
series.
- include the futex rework + requeue_pi support (Darren Hart)
The futex changes need profound testing. As we know from prior futex
work the best stress tests for the futex interface are RT-Java-VMs
especially with enterprise work loads on larger machines. Can the
folks who have access to such monstrosities please unleash the beasts
and give the futex code a good work out ? Please tell your sysadmin
upfront that he should be stand by to fix up the resulting wreckage
which might vary from harmless to system replacement.
Unfortunately I was not able to track down the weird 32bit PAE
shutdown crash, so the affected users need to stick to the
nosmp-alternatives work around for now.
