Recently installed March 12 -current snapshot and compiled kernel with new IDE subsystem. I see interesting lines in dmesg: npx0: INT 16 interface ata0: master: settting up UDMA2 mode on PIIX4 chip OK ad0: ATA-4 disk at ata0 as master ad0: 3079MB (6306048 sectors), 6256 cyls, 16 heads, 63 S/T, 512 B/S ad0: piomode=4, dmamode=2, udmamode=2 ad0: 16 secs/int, 0 depth queue, DMA mode ata0: slave: settting up UDMA2 mode on PIIX4 chip OK ad1: ATA-4 disk at ata0 as slave ad1: 6197MB (12692736 sectors), 12592 cyls, 16 heads, 63 S/T, 512 B/S ad1: piomode=4, dmamode=2, udmamode=2 ad1: 16 secs/int, 31 depth queue, DMA mode ata1: master: settting up UDMA2 mode on PIIX4 chip OK ad2: ATA-4 disk at ata1 as master ad2: 6197MB (12692736 sectors), 12592 cyls, 16 heads, 63 S/T, 512 B/S ad2: piomode=4, dmamode=2, udmamode=2 ad2: 16 secs/int, 31 depth queue, DMA mode changing root device to wd0s1a vinum: loaded vinum: reading configuration from /dev/wd2e vinum: updating configuration from /dev/wd1e ffs_mountfs: superblock updated for soft updates ffs_mountfs: superblock updated for soft updates Does it mean that new ATA disks can queue up commands (something similar to SCSI disks?)? I feel like I heard something in the -current list lately but I'm not sure... -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
