Subject: [RFC PATCH v3 5/5] block/nvme: Use qemu_vfio_pci_init_msix_irqs() to initialize our IRQ
Date: Tue, 18 Aug 2020 18:45:09 +0200 [thread overview]
Message-ID: <20200818164509.736367-6-philmd@redhat.com> (raw)
In-Reply-To: <20200818164509.736367-1-philmd@redhat.com>
Instead of initializing one MSIX IRQ with the generic
qemu_vfio_pci_init_irq() function, use the MSIX specific one which
will allow us to use multiple IRQs. For now we provide an array of
a single IRQ.
