My local supplier has started doing some SATA cards....

http://www.ivmm.com/eio/products_sata_pci_host.html


The chip on the board i the screenshot looks vaguely like a Silicon Image chip 
- - am I correct in thinking that these are supported in linux?

Cheers,

Mark.

If they are Silicon Image, yes, they are supported.

Great stuff - can someone confirm whether I still need to do the folloing for 
the latest 2.4.22 kernels in order to get good performance?

# hdparm -d1 -X66 /dev/hdX
# echo "max_kb_per_request:15" > /proc/.ide/hdX/settings

Cheers,

Mark.

I have no idea :(   I'm off in libata land, which will soon support 
Silicon Image SATA as well...

the answer is yes - there hasnt been an update to the driver. Andre
Hedrick says he has fixed it a month or so ago but has not released it
yet.

btw echo "max_kb_per_request:15" > /proc/.ide/hdX/settings is not for
good performance (it may halve your performance on some drives) it is a
bug workaround.

Look forward to testing libata on Silicon Image.

The answer is no - the siimage driver isnt maintained by Andre.

Dippy question - is libata a 2.6 thing or is it going to be backported to 2.4?

Mark,

I certainly have seen libata patches for 2.4 - search the mailinglist archive 
for libata annoucements or just do a google.

Cheers,
    Chris

It's for 2.4 and 2.6 right now.  You can get libata simply by using Alan 
  Cox's -ac patches for 2.4 or 2.6, or download directly from my FTP 
directories:
ftp://ftp.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/
(look in "2.4" and "2.6" sub-directories for *libata*)

In -ac pretty much everything "just works". Just finishing off one or
two last issues
