Subject: [PATCH 0/2] KVM: Xen PV timer fixups
Date: Wed,  9 Mar 2022 14:38:33 +0000	[thread overview]
Message-ID: <20220309143835.253911-1-dwmw2@infradead.org> (raw)

For squashing into the relevant commits already in kvm/queue, as discussed.

Note that I've switched the immediate timer delivery to just call the
xen_timer_callback() function, because I couldn't see *why* just setting
the ->arch.xen.timer_pending flag actually worked, without also setting
KVM_REQ_UNBLOCK. I suspect that the timer was only actually getting set
after the vCPU exited for some *other* reason. This should be better.

I'll follow up separately with a patch to remove __kvm_migrate_apic_timer
because it seems to be utterly pointless now.
