Alternatively you could use pci_restore_state() (before reset) and pci_save_state() (after reset) to restore standard PCI config registers (including MSI/MSI-X) after a reset. This might be more scalable if you want to ensure other PCI config registers (e.g. PCI-e capabilities) are restored after a reset. -- John Baldwin _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
