From b50cac55bf859d5b2fdcc1803a553a251b703456 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Thu, 6 Oct 2011 14:08:18 -0400 Subject: 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//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 Signed-off-by: Jesse Barnes --- include/linux/pci.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux/pci.h') diff --git a/include/linux/pci.h b/include/linux/pci.h index 7cda65b5f798..84225c756bd1 100644 --- a/include/linux/pci.h +++ b/include/linux/pci.h @@ -336,6 +336,7 @@ struct pci_dev { struct bin_attribute *res_attr_wc[DEVICE_COUNT_RESOURCE]; /* sysfs file for WC mapping of resources */ #ifdef CONFIG_PCI_MSI struct list_head msi_list; + struct kset *msi_kset; #endif struct pci_vpd *vpd; #ifdef CONFIG_PCI_ATS -- cgit v1.2.3
