[PATCH resend 0/2] kvm/msi: do explicit commit when adding msi routes

Posted by Longpeng(Mike) via 2 years, 2 months ago

From: Longpeng <longpeng2@huawei.com>

This patchset moves the call to kvm_irqchip_commit_routes() out of
kvm_irqchip_add_msi_route(). An optimization of vfio migration [1]
depends on this changes.
