Linux 2.6.28 Porting to Oxnas

[WarheadsSE]

At this point, leds are behind getting sata working.. but USB is cleaned up.

What is the status of the SATA code in V3.1?

Since I have two hard drives suitable for it, it would be possible for me to provide some testing and coding for that driver.

A clean kernel is what I am daring for on that device anyways. Same what I am currently after on that U-Boot 2011.09. Too much hack-up in the U-Boot 1.1.2 code, too.

It's not working :p

[ftcodes]

Thats why I mentioned testing and coding.

$this->bbcode_second_pass_quote('ftcodes', 'W')hat is the status of the SATA code in V3.1?

[ftcodes]

I know and got an answer which definitely ranks to coding badly needed. I think practicing on that U-Boot first will give me the understanding for that SATA core anyways.

[ftcodes]

There is definitely some code which the Medion NAS Kernel has. I will check on that when I know that I can get the SATA code working on the U-Boot 2011.09. U-Boot porting is a lot simpler than kernel porting. From my point of view, the 3.1 kernel is definitely worthy to be used as a basis for cleaning up that OX820 driver.

Do you have a .config for me to compile that kernel? Since it keeps telling me about exceeding the Leon SRAM.

make ox820_pogoplug_defconfig

I reorganized that beast as you can see here https://github.com/ft-/OX820-3.1-Linux.
I have not yet had the ability to test it. My device is sitting at home but not me.

Short summary about changes:
- Reorganized code structure
- Moved config parameters into module parameters
- Added LED trigger support
- Removed Direct SATA stuff
- Removed complex locking stuff from Direct SATA and MD hwraid bridging. (Not supported by 3.1 SATA layer anyways)
- Fixed PRD stuff (Important bits that were missing)
- Corrected indentation

If you like, you can try it but I cannot tell yet whether it will work. Not tested as of now but that will come when I am back at home.
