So this patch make compatible with longterm kernel linux-2.6.32.63. For RHEL, function pci_num_vf() begins from RHEL5 update9. And it is stub-defined when CONFIG_PCI_IOV is not enabled. So dropped the CONFIG_PCI_IOV checking of commit 11ba0426. For other distro like RHEL behaved to pci_num_vf(), we could simply append following condition macro: (!(defined(OTHER_RELEASE_CODE) && \ OTHER_RELEASE_CODE >= OTHER_RELEASE_VERSION(X, Y))) Signed-off-by: Jincheng Miao Acked-by: Thomas Monjalon --- diff --git a/lib/librte_eal/linuxapp/igb_uio/compat.h b/lib/librte_eal/linuxapp/igb_uio/compat.h index 676fa1b385..00934d82e6 100644 --- a/lib/librte_eal/linuxapp/igb_uio/compat.h +++ b/lib/librte_eal/linuxapp/igb_uio/compat.h @@ -21,7 +21,8 @@ #endif #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 34) && \ - !defined(CONFIG_PCI_IOV) + (!(defined(RHEL_RELEASE_CODE) && \ + RHEL_RELEASE_CODE >= RHEL_RELEASE_VERSION(5, 9))) static int pci_num_vf(struct pci_dev *dev) {
