AHCI driver commited

Hi,
I've just commited an ahci driver. Works fine for me on Intel 63xxESB AHCI
controller:
ahcisata0 at pci0 dev 31 function 2: Intel 63xxESB AHCI Serial ATA Controller
ahcisata0: AHCI revision 1.0, 6 ports, 32 command slots, features 0xc6226000
ahcisata0: interrupting at ioapic0 pin 19 (irq 10)
atabus0 at ahcisata0 channel 0
atabus1 at ahcisata0 channel 1
atabus2 at ahcisata0 channel 2
atabus3 at ahcisata0 channel 3
atabus4 at ahcisata0 channel 4
atabus5 at ahcisata0 channel 5
ahcisata0 port 0: device present, speed: 3.0GB/s
ahcisata0 port 2: device present, speed: 3.0GB/s
wd0 at atabus0 drive 0: <Hitachi HDS721616PLA380>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 153 GB, 319120 cyl, 16 head, 63 sec, 512 bytes/sect x 321672960 sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd0(ahcisata0:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133) (using DMA)
wd1 at atabus2 drive 0: <Hitachi HDS721616PLA380>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 153 GB, 319120 cyl, 16 head, 63 sec, 512 bytes/sect x 321672960 sectors
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd1(ahcisata0:2:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133) (using DMA)

Note that this driver will only attach if the controller is in AHCI mode
(there's usually a BIOS option for this); if it's in compat mode it'll
be handled by piixide as before.

Thanks - on a dual-core Thinkpad T60 the new code boots and runs fine.

Yay thanks !

ahcisata0 at pci0 dev 31 function 2: Intel 82801H AHCI SATA Controller
with 4 ports
ahcisata0: AHCI revision 1.0, 4 ports, 32 command slots, features
0xff22e0c0
ahcisata0: interrupting at ioapic0 pin 19, event channel 7
atabus2 at ahcisata0 channel 0
atabus3 at ahcisata0 channel 1
atabus4 at ahcisata0 channel 4
atabus5 at ahcisata0 channel 5

wd0(ahcisata0:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6
(Ultra/133) (using DMA)

Does it give any improvement ?

Thanks!

With more than 2 drives, yes. Also there will be NCQ support in the
future.

Seems to be working fine:

ahcisata0 at pci0 dev 31 function 2: Intel 82801GBM AHCI SATA Controller
ahcisata0: AHCI revision 1.0, 4 ports, 32 command slots, features 0xdf12e000
ahcisata0: interrupting at ioapic0 pin 17 (irq 10)
atabus1 at ahcisata0 channel 0

(this is an HP nx6310 laptop - I have put a few questions about it earlier).

Ofcourse, that should be either 3Gbps (raw), 2.4Gbps (10B/8B encoding), 
375MB/s (raw) or 300MB/s (10B/8B encoding).

Otherwise, very nice :).

Cheers,
