From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jan Kiszka Subject: [PATCH v3 0/4] KVM & genirq: Enable adaptive IRQ sharing for passed-through devices Date: Mon, 13 Dec 2010 23:59:42 +0100 Message-ID: Cc: linux-kernel@vger.kernel.org, kvm , Tom Lyon , Alex Williamson , "Michael S. Tsirkin" To: Thomas Gleixner , Avi Kivity , Marcelo Tosatti Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: kvm.vger.kernel.org This addresses the review comments of the previous round: - renamed irq_data::status to drv_status - moved drv_status around to unbreak GENERIC_HARDIRQS_NO_DEPRECATED - fixed signature of get_irq_status (irq is now unsigned int) - converted register_lock into a global one - fixed critical white space breakage (that I just left in to check if anyone is actually reading the code, of course...) Note: The KVM patch still depends on http://thread.gmane.org/gmane.comp.emulators.kvm.devel/64515 Thanks for all comments! Final but critical question: Who will pick up which bits? Jan Kiszka (4): genirq: Introduce driver-readable IRQ status word genirq: Inform handler about line sharing state genirq: Add support for IRQF_COND_ONESHOT KVM: Allow host IRQ sharing for passed-through PCI 2.3 devices Documentation/kvm/api.txt | 27 ++++ arch/x86/kvm/x86.c | 1 + include/linux/interrupt.h | 15 ++ include/linux/irq.h | 2 + include/linux/kvm.h | 6 + include/linux/kvm_host.h | 10 ++- kernel/irq/manage.c | 77 ++++++++++- virt/kvm/assigned-dev.c | 336 ++++++++++++++++++++++++++++++++++++++++----- 8 files changed, 436 insertions(+), 38 deletions(-)
