Note that this will renumber IRQ values. If you are used to seeing IRQ values > 256 as meaning MSI, that will no longer be true. If you must know which interrupts are MSI you can check the machdep.first_msi_irq sysctl. I've also considered renaming them to 'msi' instead of 'irq' in vmstat -i output. We still have to have a number for cpuset -x to work, otherwise we could name MSI interrupts after the device perhaps. -- 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"
