[Xen-devel] RT-Xen on ARM

Dear Meng Xu,

We are going to evaluate an RTDS scheduler on ARM.

Basically I'm going to repeat use-cases described in https://www.cis.upenn.edu/~linhphan/papers/emsoft14-rt-xen.pdf in some amount.

Do you have any recommendations or suggestions?

BTW, even following https://xenbits.xen.org/docs/unstable/features/sched_rtds.html I've faced several issues, not rtds one, but nasty:

- no xentop for ARM

- root@salvator-x-h3-xt:/scripts# xl sched-rtds -d DomU -v all -p 10000 -b 2500
  (XEN) FLASK: Denying unknown domctl_scheduler_op: 2.
libxl: error: libxl_sched.c:663:sched_rtds_vcpu_set_all: Domain 2:Setting vcpu sched rtds: Operation not permitted
  libxl_vcpu_sched_params_set_all failed.
