Happy New Year, libata hackers

Happy New Year, libata hackers

[Jeff Garzik]

Well, another year has passed, and somehow the duct tape that keeps our 
hard drives together has remained intact.  After a nice and refreshing 
holiday, I have a bunch of patches pending, that will probably take a 
week or two to sort through.

For 2.6.16, my main goals are getting irq-pio upstream and supporting 
iomap -- which will kill all those annoying warnings finally.  And 
probably some EH work from Tejun will go in too.  The suspend/resume 
stuff is shaping up nicely, and device hotplug work suddenly reappeared. 
  Fun for all.

Port multiplier and NCQ (queueing) support are the two other big to-do 
items on the list.

I updated the hardware status report at
	http://linux.yyz.us/sata/

and will update the software status report in a week or two.

Everybody wants to play in the same sandbox, so please be patient as we 
sort it all out.

Cheers and happy new year,

	Jeff

I'll get NCQ updated and tested again in the not-so-distant future.

FWIW I've kept it moderately up-to-date in the 'ncq' branch.  It's 
definitely moldy, with a few FIXMEs in libata-scsi's read/write 
translation, for example, which is missing the NCQ portion of that code.

Yeah that, and Tejun had some good updates for it as well. I'll take a
look as soon as I get some time to do so.

+ selectable debugging macros etc.
  (used in ACPI suspend/resume patches, but can be used in all of libata)

Great to hear that!

Just took a look at it. So finally Nvidia gave out some specs:-)

I thought I would never use NCQ  with my NFORCE4

Hi, Jeff.

I am confused a bit by the SATA status.

I have a Promise SATA TX2plus, which has a channel for PATA along with SATA.

The status report seems to say there is no support for the PATA side, 
but then says there was, at least in September.

Is there PATA+SATA support or was it removed for some reason?

Best regards,
Matt Reuther
