The Linux Plumbers Conference blog has a
report from the sched_ext microconference held in Prague.

Three main topics dominated the discussions

• Priority inversion and how to handle it in sched_ext: lock holder and
  lock waiter preemption, time slice extension, and making proxy execution
  work together with BPF schedulers.
• Paravirtualized scheduling: letting the host and guest schedulers
  cooperate across the VM boundary, with sched_ext as the policy engine on
  the host.
• Device and topology-aware scheduling: using hardware feedback (Intel
  HFI), device/accelerator locality and cache topology to drive task
  placement.
