SATA status report updated

[Jeff Garzik]

Things in SATA-land have been moving along recently, so I updated the 
software status report:

	http://linux.yyz.us/sata/software-status.html

Although I have not updated it in several weeks, folks may wish to refer 
to the hardware status report as well:

Thanks to all the hard-working SATA contributors!

Is any progress made on SMART support ?
I've been reading "SMART support will be integrated very soon"
for a very long time now .. :-)

Yup, thanks to you & them.  SATA has been working perfect in my system
since I started using it 10 months ago !

True enough :/

It's been feature-complete for a while, but the reports from testers in 
the field have made me too nervous to push it into the upstream kernel.

I might push it upstream, but disable it by default, which would allow 
for a wider test audience.

Could you specify what tests and reports would be useful and what risks
are involved?
Eg If I have 2 SATA drives then could (OK, of course it *could* - but is
it likely) I break sda whilst testing with sdb? I can live with crashes
and hangs and I can mitigate data loss, but I may think twice if it'll
toast the drive.

Nb: I often think that if people bemoaning the lack of testers put a bit
of effort into saying what tests would be useful then more people would
run them.
"Here run this and just say if it crashes" is one approach.
"Try these options, use smartd, turn on debugging like this and send
this part of the output if you have a problem. Previously reported
problems include: <blah, blah blah>. Oh, it's only ever going to affect
the drive you specify and the worst case scenario is a low-level format
using the vendor's download (which may or may not be available)" - makes
me more aware of what I'm getting into.

I couldn't see any reference to system-wide power management (ie,
suspend/resume of machines with SATA interfaces) - is any work going on
in that area at the moment?

Jens Axboe @ SuSE posted a patch that needs some work.  So, it's on the 
radar screen, but I haven't seen any new work recently.

Ah, the sata-suspend patch. Also very needed. Extensively used over here
on various kernels (2.6.11 and 2.6.12 versions), no problems, works like
a charm imho.

Good write up.  I like the simplicity of error handling.

Thumbs up!

I guess this means libata support for HW-based NCQ.
It also could mean software/driver implemented NCQ, which could work on 
chipsets not supporting HW-NCQ in unison with a disk having NCQ?

How well does libata work with the newest ULi chipsets?
If not well, is there a possible timeframe?


(not on kernel list; if anyone there comments on ULi, pls. cc private)

NCQ by definition -requires- support in the controller chip.

No idea.  I don't see many bug reports, so I suppose its OK.

Good overview!

I'm wondering how the support for the SIS 182 controller is doing, I 
noticed they have a GPL driver on their website for kernel 2.6.10, which 
is not a drop in replacement for sata_sis.c in 2.6.12.5, I haven't tried 
compiling it as an add-on module outside the tree, though...

Adding the 0x182 identifier to the 180 driver does compile (duh!), but I 
haven't tried it on hardware.

As a temporary measure, there was a patch posted to this list [1] a 
while ago, would it be a good idea to include this while full support is 
being worked on?

Cheers

Simon

Jeff, is it possible for you at this time to comment on support for the 
JMicron JMB360 sataII chip?  Possible timeframe?
It's starting to be used with the ULi M1695/M1567 chipset.

Neigher had I. It's being used on the ASrock 939-SATAII mobo, in 
conjunction with the ULi M1695 chipset. I wonder why they chose an 
unknown SATAII chip for this. The M1695 already has two SATA150 
interfaces, and the only test I've seen with SATAII on this mobo used a 
SATA150 disk on that JMB360 interface - with poorer results than on the 
regular ifc. Could be due to the chip, BIOS, (xp) driver...

The rest of the tests came out pretty good, and the board is well 
featured, so naturally I'm interested in possible libata support.
