Hi,
Hi,
I remember this discussion. The problem was that the PMU is using
per-CPU interrupts. Xen is not yet able to handle PPIs as they often
requires more context to be saved/restored (in this case the PMU context).
There was a proposal to look if a device is using PPIs and just remove
them from the Device-Tree. Unfortunately, I haven't seen any official
submission for this patch.
But we have this patch that remove devices using PPIs

Urgh, I forgot we merged it. I should have double-checked the tree.
Apologies for that.
Cheers,
