** Description changed: - Multiple regression tests are failing on the linux-xilinx-zynqmp/focal kernel when calling sched_setscheduler() or with related operations. This is probably caused by enabling CONFIG_RT_GROUP_SCHED since similiar issues have been seen when enabling this config on other kernels. The following tests are failing with this error: + The focal kernel is failing the ubuntu_ltp:sched:time-schedule01 and + ubuntu_ltp:sched:trace_sched01 regression test due to sched_setscheduler + being unable to a task class to SCHED_FIFO. + + There are multiple known issues with CONFIG_RT_GROUP_SCHED that are reported in the debian.master/config/annotations file: + https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1284731 + https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873315 + https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875665 + + We do not have a good reason to enable this , I see no processes using realtime scheduling.
