  • Thread-topic: Problems with Xen/ia64 on xen-unstable tip

In preparing to catch up with the backlog of patches due
to the switchover from bk to hg, I grabbed the latest
tip for xen-unstable.hg.  Unfortunately, it doesn't work.
After limited debugging, it appears that the sedf
scheduler (recently changed from bvt) doesn't work in Xen/ia64
and (after changing this back to see if I get further)
a hypercall to HYPERVISOR_event_channel_op fails
(possibly due to an interface change?).

These failures are due to recent Xen core changes as
a previous tree worked fine.

I will have limited time to track these problems down
in the next couple of days (and all patches are on hold
until tip runs); if someone else could volunteer to track
these down and identify fixes, I would very much
appreciate it!

Thanks,
Dan
