Subject: [PATCH 0/3] KVM: Improve IRQ assignment for device passthrough
Date: Mon, 1 Nov 2010 15:08:34 +0100 [thread overview]
Message-ID: <cover.1288620511.git.jan.kiszka@web.de> (raw)
Three patches to improve "classic" device assigment /wrt IRQs. Highlight
is the last one that resolves the host IRQ sharing issue for all PCI 2.3
devices. Quite essential when passing non-MSI-ready devices like many
USB host controllers.
Jan Kiszka (3):
KVM: Fold assigned interrupt work into IRQ handler
KVM: Clear assigned guest IRQ on release
KVM: Allow host IRQ sharing for passed-through PCI 2.3 devices
