backport of the upstream kernel commit da8d1c8ba4dcb16d60be54b233deca9a7cac98dc commit da8d1c8ba4dcb16d60be54b233deca9a7cac98dc Author: Neil Horman <nhorman> Date: Thu Oct 6 14:08:18 2011 -0400 PCI/sysfs: add per pci device msi[x] irq listing (v5) This patch adds a per-pci-device subdirectory in sysfs called: /sys/bus/pci/devices/<device>/msi_irqs This sub-directory exports the set of msi vectors allocated by a given pci device, by creating a numbered sub-directory for each vector beneath msi_irqs. For each vector various attributes can be exported. Currently the only attribute is called mode, which tracks the operational mode of that vector (msi vs. msix) Acked-by: Greg Kroah-Hartman <gregkh> Signed-off-by: Jesse Barnes <jbarnes> this is required bits for the feature request from bug 710576, in priority list.
