AFAICS it just continues - ie if you wanted to boot into multi-user, 
you'll get this one.

 I am particularly interested in systems which have a separate,
 traditional non-AHCI ATA device as well as one or more AHCI
 devices, I'd like to know that AHCI picks up the AHCI devices and NATA
 picks up the non-AHCI devices properly.

Seems to work here on my laptop. I'm not brave enough to do any stress 
tests though ;).

I have an old motherboard with 2 non-AHCI SATA controllers. Despite preloaded

Re: AHCI driver port update - working with hot-plug

:I have an old motherboard with 2 non-AHCI SATA controllers. Despite preloaded
:ahci.ko booting the latest snapshot gives the following:

Sure, that's to be expected.  Since they aren't AHCI-capable the
AHCI driver did not pick them up, and the ATA driver did.  That's
a good test too, we don't want the AHCI driver trying to pick up
non-AHCI ATA devices :-)

AHCI driver port update - working with hot-plug

2009-06-06 Thread Matthew Dillon 
The AHCI driver is now working for DISK and ATAPI attachments, and
hot-plug also now works.

All major features except port multiplier support are now operational.

The hot-plug support is very recent and probably needs some tweaking,
but it works with my basic tests.

Port multiplier support is upcoming, I expect to get it written fairly
quickly once I get the PM hardware I've ordered.


TESTING (not for the light hearted)


Both the AHCI and the NATA devices may be specified in kernel builds,
and AHCI can be loaded as a module too which is how I would suggest
people use it for the moment.  That is, you can leave NATA in your
kernel build and load AHCI as a module in /boot/loader.conf:

ahci_load=YES

Note that you must do a full kernel build and install to make sure
everything is in sync.

Your ATA disk devices, for example, 'ad4', will become SCSI disk devices,
for example 'da0'.  You thus need to modify your /etc/fstab and if you
are using a boot + root HAMMER configuration you also need to adjust
the root filesystem mount line in your /boot/loader.conf.

It's fairly easy to get it wrong and for the system to not be able to
find the root mount, in which case carefully specifying it on the
kernel's mountroot line should get you into single-user.

I am particularly interested in systems which have a separate,
traditional non-AHCI ATA device as well as one or more AHCI devices,
I'd like to know that AHCI picks up the AHCI devices and NATA picks
up the non-AHCI devices properly.
