From 4c89e3e59368584ae6f34fdfce3c698223b8a918 Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Mon, 7 Oct 2013 10:36:37 +0300 Subject: hw/vmxnet3: set interrupts using pci irq wrappers pci_set_irq uses PCI_INTERRUPT_PIN config register to compute device INTx pin to assert/deassert. An assert is used to ensure that intx received from the quest OS corresponds to PCI_INTERRUPT_PIN. Signed-off-by: Marcel Apfelbaum Signed-off-by: Michael S.
