-bodhi,

Thanks for your input :-)
I know and I allready have a pogoE02 but I liked the opinon of a dualcore and 2sata's and to all of it the KD20 had just a nice price ( 40€) .

Back to topic:

I have already looked at these lines but have only a vage Idea what to extract from the gpl sources.
Somehow I have the feeling that the whole sata driver in Kref's repo is hardcode or just dont have a 2 port option. Maybe Warhead has here a Info about that.

I try & error a bit to to make something like in the two port krikwood.dtsi

The more I dig around, the more the described entry from bodhi seems accurate.

This only real difference I see is that you need to have the port @ 0x45910000, and they appear to have the same DMA/SGDMA/etc.

Good hints! then cloning the second port from the first one is straight forward.

Thanks to both of you.

I tried to add to
dts:
	sata@45910000 {
		status = "okay";
	};
dtsi:
	sata@45910000 {
		compatible = "plxtech,nas782x-sata";
			/*	port		sgdma		core	*/
		reg = <0x45910000 0x100>, <0x459B0010 0x10>, <0x459E0000 0x2000>,
			/*	phy		descriptors (optional)	*/
			<0x44900000 0x0C>, <0x50000000 0x1000>;
		interrupts = <0 18 0x304>;
		clocks = <&stdclk 4>;
		resets = <&rst 11>, <&rst 12>, <&rst 13>;
		reset-names = "sata", "link", "phy";
		status = "disabled";
	};
And changed the max ports from 1 to 2. in the sata_oxnas.c
SATA_OXNAS_MAX_PORTS	= 2

Compiling was ok, but the kernel panics:

It would probably be est to get the sata@ so that it doesn't think there are actually 2 entries, but that you can specify nr-ports 2, and it uses the second port @ +0x10000

I tried yesterday something like that - maybe I did it wrong - and adaped the syntax for the krikwood 2 port devices.
With these enteries
DTS:
sata@45900000{
			nr-ports = <2>;
			status = "okay";
DTSI:
	sata@45900000{
			compatible = "plxtech,nas782x-sata";
			/*	port		sgdma		core	*/
		reg = <0x45900000 0x100>, <0x459B0010 0x10>, <0x459E0000 0x2000>,
			/*	phy		descriptors (optional)	*/
			<0x44900000 0x0C>, <0x50000000 0x1000>;
		interrupts = <0 18 0x304>;
		clocks = <&stdclk 4>;
		resets = <&rst 11>, <&rst 12>, <&rst 13>;
		reset-names = "sata", "link", "phy";
		phys = <&sata_phy0>, <&sata_phy1>;
		phy-names = "port0", "port1";
		status = "disabled";
		};		
 sata_phy0: sata-phy@45900000 {
			compatible = "plxtech,nas782x-sata";
			reg = <0x45900000 0x100>;
			clock-names = "sata";
			#phy-cells = <0>;
			status = "ok";
		};

		sata_phy1: sata-phy@45910000 {
			compatible = plxtech,nas782x-sata";
			reg = <45910000 0x100>;
			clock-names = "sata";
			#phy-cells = <0>;
			status = "ok";
		};

But I get with these configs compiling errors with "no entery for sata_phy0" and something like these.
So I changed it to 2 sata enteries and now it compiles the kernel and somehow finds the second sata, but with errors.
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)
September 30, 2014 04:32PM
Yes.. because it is attempting to treat it as 2 separate PHY. There is only 1.
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)
October 01, 2014 07:32AM
Okay, I see what you mean.

But how can I use 2. ports on one PHY? I see here nothing in the driver code nor I have any Idea how to insert the second correctly into the dts.
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)
October 01, 2014 03:13PM
I am saying it needs added.
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)
October 03, 2014 02:51AM
Am I understanding you right:
The 2 port option has to be integreated in the sata_oxnas driver, and not only activated? As I have absolutly no idea how to do this as the structure from the old driver is totaly diffrent to the newer one.

If it's right, maybe - for me - it is easyer to integrade the vendors sata driver in the new kernel.
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)
October 03, 2014 07:22AM
Except, the vendors sata driver will 99% likely not work with the newer kernel. I have seen that pile of steaming crap.

:) yes.

@peacemaker, I think the correct DTS syntax for 2 SATA ports is what you need.

Big thanks to both of you.
I'll see what I can do. But I have first to undersand how the driver works (old and new) to patch the second pord in. But this is the first time I try something like this.

And your right with this vendor's sata, I've not beliefed how many warnings( used init's instad of pointers...) and errors there are to fix :-/

The new driver is robust enough that it seems the necessary change might be as simple as this:

drivers/ata/sata_oxnas.c

SATA_OXNAS_MAX_PORTS = 2,

I already tried this and then I get a kernel panic. (posted it earlyer).

Maybe I had the wrong syntax in the dts(i), but I don't even see how the driver read the dts and switches between ports like the vendors driver.
So there might be more to do. I guess this driver is written for single sata, as the SATA_OXNAS_MAX_PORTS is hardcoded and not readed from dts.

But I'm happy about any input, to figure out how to enable the second port.

Yes. I think possibly the kernel caused a panic is because of your dts. FDT is relatively new, so you wont find lots of drivers that have code handling it directly. Instead, this sata driver is typical (eg. sata_mv). As long as you have both dts and driver in sync then it will hopefully initialize the ports.

Hey, so I tried to understand what is causing exectly the kernel panic.

What I think is the core of the Problem:

void __iomem *port_base[SATA_OXNAS_MAX_PORTS];
void __iomem *sgdma_base[SATA_OXNAS_MAX_PORTS];

Here you get with max_ports=2 an array of 2. And thow I have to write an Array and only a number.

So I tried to change this
ata@45900000 {
		compatible = "plxtech,nas782x-sata";
			/*	port		sgdma		core	*/
		reg = <0x45900000 0x100>, <0x459B0000 0x10>, <0x459E0000 0x2000>,
			/*	phy		descriptors (optional)	*/
			<0x44900000 0x0C>, <0x50000000 0x1000>;
		interrupts = <0 18 0x304>;
		clocks = <&stdclk 4>;
		resets = <&rst 11>, <&rst 12>, <&rst 13>;
		reset-names = "sata", "link", "phy";
		status = "disabled";
	};
to this
ata@45900000 {
		compatible = "plxtech,nas782x-sata";
			/*	port		sgdma		core	*/
		reg = <0x45900000,0x45910000 0x100>, <0x459B0000,0x459B0010 0x10>, <0x459E0000 0x2000>,
			/*	phy		descriptors (optional)	*/
			<0x44900000 0x0C>, <0x50000000 0x1000>;
		interrupts = <0 18 0x304>;
		clocks = <&stdclk 4>;
		resets = <&rst 11>, <&rst 12>, <&rst 13>;
		reset-names = "sata", "link", "phy";
		status = "disabled";
	};

To give write an array, but I got syntax errors. :-(

I've not an idea how the device tree writes into an array in this file. And I don't found a helpfull manual to this.

Maybe someone have an idea or a link, that is helpfull

<0x45900000,0x45910000}
That } is a problem.

And we still need it to truly understand it is _one_ controller with _two_ ports. This really needs to be handled @ the driver code, and then only the difference adjusted @ the dts would be nr-ports.

Sry warhead I do not realy get what you mean.

I realized that this board has 1 sata controler (phy) with 2 ports.
The number of ports is at the moment hardcoded, and as I see it this controls just the arraysize of 2 pointers.
I think the kernel panics because only the first entery of these arrays are written. My appproch was now, why don't easy write an array of an register instat of a single register.

Maybe you can tell me what is wrong with this idea

Sure, but why do you think the drive is goning to inital the controller a second time, with an arraysize of 2 instead of 1 ?

As I read the bootlog it panics on instand, and there is no second initial with SATA_OXNAS_MAX_PORTS = 2
Re: Debian on Shuttle KD20 (PLX OXNAS 7821)

Thanks, Warhead
I see that the *.dts does not accept an array.

But what do you think of the array in the driver (sata_oxnas.c)? In the vendores driver there are similar code for the with an pointer-array for the port address.

In order to support more than 1 port, proper locking got to be implemented in the sata_oxnas driver.
The vendor SDK uses a quite complex setup for that to allow both, direct access and hardware raid with two disks. As we are quite far from supporting hardware-raid features in vanilla kernels, the best for now would be to implement locking as seen in
https://raw.githubusercontent.com/hynnet/hiwifi-openwrt-HC5661-HC5761/master/target/linux/oxnas/files-3.3/drivers/ata/sata_ox820.c
and having device-tree nodes for each port/phy and add them to the controller, similar to how it's done in
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/kirkwood.dtsi

If I find the time, I'll give it a shot somewhen in the next days...

Hey, your right so far, Warhead has this driver in an old git. https://github.com/WarheadsSE/OX820-3.1-Linux

And beside from raid, cardreader, front usb3.0 and gpio, this non-fdt works so far.

The cardreader, front usb3.0 and gpio is I not the hard task.

With try to use the raid here I got:

I'm not sure if this driver is capable of fdt, so maybe it might be better to work on the "newer" sata driver and add there the second port. But after many hours of looking into the code of the sata_oxnas.c I realized my coding skills are to low :-(.

So - do you think it might be possible to use the second port only with a couple of changes and leaving first port unused?

It might help make both sata ports work if there was possibility to make them work separately first. If there was some way to find out what it needs to change used port, it might be a step forward.

Ohhhhh,... this is looking not so bad.

I compiled this openwrt, for so far, it is working.
+ uboot find 2 HDD
+ openwrt find 2 HDD
- Uboot Mac address must be set manual
- usb is not working (ehci timeouts)

But as I'm not a big fan of openwrt on a nas, I'll try to patch this for the debian-kernel.

For now on everything compiles quite well but I've got to fix the machine ID, as I got an error within wrong ID
