Linux 2.6.28 Porting to Oxnas

[WarheadsSE]

Great, you noticed that it was based on the 934 I will give it a shot when I get a chance.

Did you adjust the defconfig?

[ftcodes]

I did not yet remove the config parameters from the kernel config if you mean that. I wanted first to get the source done.
And I did notice that chip name.

[WarheadsSE]

I built it:
- make ox820_pogoplug_defconfig
- make menuconfig & enable sata as a built-in
- make
- booted: sata didn't initialize.

[ftcodes]

So there is still some work to do on it. But since I had no ability yet to test, I did not expect it to work out of the box.

Have you had at least some dmesg lines about it?

[ftcodes]

I added a line printing as follows:

sata_ox820.c: Initialization result %u at %u

to see at least something.

In a few days, I will let it run on my device and check what goes wrong. Maybe tons of printk.

[ftcodes]

That looks like a nice beginning of a more clean version of that driver.
Detection seems to be okay, so stability testing has to be done and probably some fixing.

The kernel I used as a basis was from the Medion which had some stuff that did not exist in the other versions. When I compared them, it looked like Medion had the newest variant of those patches. Especially, due to the fact that they delivered working XFS support with that PLX hacked stuff.

In addition, I cleaned up the initialization (double module_init changed to single module_init).

Looks like USB got precedence over SATA but that can be solved by using disk uuid reference. The sd* naming scheme is not so predictable.

[WarheadsSE]

There are some issues with UUID:
- Cant it can change from install to install/format?

The goal is to get this all working, then bring it into the ALARM mainline, and get kexec & all the rest of support. Then, I will nuild a kexecboot kernel that will be able to boot from USB/SATA

[ftcodes]

Did you get the Ethernet driver clean?

An installed system can be changed from sdX references to UUID. The only thing you need is to extract the UUID references.
Typical references for that are /dev/disk/by-uuid/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

AFAIK, Linux accepts that modification without any reinstall.

You can call tune2fs -l /dev/sda2 on ext2/3/4. Similar calls should exist for other filesystems.
The Filesystem UUID is used for that type of reference.

An example for it:
In the output you find following:

Filesystem UUID: 12345678-1234-1234-1234-123456789abc

Then the reference would be:
/dev/disk/by-uuid/12345678-1234-1234-1234-123456789abc


"Bring it to mainline"
That is the idea why I cleaned that thing up.


IMHO the moving of Kconfig parameter into module parameter should be done on the ehci-oxnas driver as well. If there are some in the Ethernet driver it should be done too. Maybe not all work out but at least the ones that change with particular boards.
