Debian on Synology RS816 (Armada 385)

@bodhi

I have installed Debian-4.12.4-mvebu-tld-1-rootfs-bodhi.tar.bz2 to HDD but will stick with tftp for kernel / dtb files as its easier to swap them out if we are testing things.

Just as a reminder to boot linux-4.12.4-mvebu-tld-1 we need to use ds116.dtb and that only brings up one sata port, so I have upgraded to to linux-4.20.6-mvebu-tld-1 and then using your amarda-385-synology-816.dtb version 1 I get two sata ports which are the first two drives from the left facing the NAS. The second drive is seen as /dev/sda the first as /dev/sdb.

I have added build-essential and various other tools to the rootfs and plan to do all work directly on the NAS, I have added 2GB of swap to help in this regard.

Was thinking we should probably add version numbers to DTB's if we are going to have a few or one of us will loose track of which is which.

Tomorrow I will test with armada-385-synology-816.dtb version 2 and see which drive bays are bootable with that one.

I too, think that will help greatly to do it natively on this box. With its horse power, you can build the kernel with my patch and config file quickly when you need to.

Good idea :)

One things that bothers me is why I could not find any trace of the RS 816-specific patch in the GPL kernel source code on Synology web site. Perhaps it is not up to date.

The RS816 was released August 2016, the RS815 was released April 2015 and used the same armada-38x with the only meaningful difference between the two models being a bump in speed from 1.33 Ghz to 1.8Ghz. All models previous to the RS815 used armada-37x. The latest Synology GPL is November 2017 whilst the first preceding version without armada-38x in it was December 2014.

Based on the above I think we should find what we need for the RS816 in the released GPL and perhaps the best way forward is hunting for changes between the two GPL dates. I will make a start doing this but Synology switched from a single download to split downloads which may hamper a simple diff between the two.

@bohdi

I have run armada-385-synology-rs816-v2.dtb (note the v2) which is the last version you provided with just pcie2 enabled expecting to see the drive the rootfs is reported on changed or even needing to move the HDD to drive 3 or 4 before its seen but basically nothing changed drive 1 is still seen as /dev/sdb and drive 2 as /dev/sda I'm starting to wonder if the DTB is having much impact on the drive initialization and its more in the kernel.

I have taken a quick look at the Dec 2014 GPL and was surprised that the Synology specific customization were limited to half a dozen kernel config options compared to the Nov 2017 which has dozens. I need to work through them but that is going to take time. I think Synology are just replacing source code by individual file, I'm sure they have patches but they are not sharing those so for each file we think may be important we need to take a diff against an original to see what they have changed.

Meanwhile partly to check my build environment is good but also out of unfounded optimism something might improve I am compiling Linux-5.1 with your patch applied and your config. I will report back when it is done.

In a modern kernel running with device tree, there should be nothing in the kernel code that needed to trigger the SATA activation. It's all in the DTB.

Stock kernel might be taking a lazy approach, when they just patch some code so they don't have to update the DTS.

I'm building and testing kernel 5.1 for Kirkwood and MVEBU boxes right now. I should have it ready for release here soon.

Understood on the DTB, guess we just need to find out what we are missing.

My build environment is all good

uname -a

Linux debian 5.1.0-tld-1 #1 SMP PREEMPT Tue May 7 12:34:41 PDT 2019 armv7l GNU/Linux

But no change in sata ports

Anything you would like me to concentrate on if we're not hunting in kernel source for answers ?

Cool!

Since you can recompile the DTB at will now. I think you can try to activate the pcie3 and pcie4 to see if it will make any difference.

In our armada-385-synology-rs816-v2.dtb right now, only 1 pcie is enabled.

pcie {
                        
			status = "okay";

			pcie@2,0 {
				/* Port 1, Lane 0 */
				status = "okay";
			};

		};

You can try to modify the DTS and compile version 3

pcie {
                        
			status = "okay";

			pcie@2,0 {
				/* Port 1, Lane 0 */
				status = "okay";
			};
			pcie@3,0 {
				/* Port 2, Lane 0 */
				status = "okay";
			};

		};

And try then version 4, with pcie4 enabled.

If any of the 2 tweaks above brings up another SATA, then we know the PCIe ports are configured as X1 port.

See the comments about these PCIe ports in

arch/arm/boot/dts/armada-385.dtsi

Tried pcie 2 and 3 enabled then pcie 2, 3 and 4 enabled but still only 2 sata ports brought up on both trials with the rootfs displayed as /dev/sdb in drive 1 viewed from from front, left to right.

OK, so this behavior seems to indicate a need to turn on power for the other ports.

Let's look back in this thread to see what zifxify did with GPIO. I recall something about some GPIO that can be a trigger for the other HDD port.

I'll look at the DTS again to confirm.

@bodhi
I've looked back at zifxify efforts with the gpio which seemed to be on the right track but no conclusive solution at the end of it. I have dumped debugfs for the gpio pins output below.

root@debian:~# cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-31, parent: platform/f1018100.gpio, f1018100.gpio:
 gpio-13  (ds116:orange:disk   ) out lo
 gpio-15  (pwr-sata0           ) out hi

gpiochip1: GPIOs 32-59, parent: platform/f1018140.gpio, f1018140.gpio:
 gpio-48  (soc:gpio-fan        ) out lo
 gpio-49  (soc:gpio-fan        ) out lo
 gpio-50  (soc:gpio-fan        ) out hi
 gpio-58  (usb3-vbus0          ) out hi
 gpio-59  (usb3-vbus1          ) out hi

One other thing I was wondering if we should strip the DTB down to the bare essentials in case the ds116 we are basing on actually reserved pins we need ?

EDIT
The above carried out with armada-385-synology-rs816-v4.dtb which I have attached.

Hi Richard,

Yes, good idea to see if we can remove GPIO definition to avoid conflict. Even though they (DS116 and RS816) are from the same manufacturer, GPIOs are reassigned as convenient for a specific box.

There are several GPIOs that are fixed location as the SoC needs them. But when you see LEDs or Fan GPIOs, you can do the test in Linux to see if they are the same and remove them if they are not.

For example,

gpio-leds {
			compatible = "gpio-leds";

			/* The green part is on gpio0.20 which is also used by
			 * sata0, and accesses to SATA disk 0 make it blink so it
			 * doesn't need to be declared here.
			 */
			orange {
				gpios = <&gpio0 13 GPIO_ACTIVE_HIGH>;
				label = "ds116:orange:disk";
				default-state = "off";

Here is the userspace GPIO control method. I have included this in the Wiki thread under

Quote

How to control GPIO in Linux userspace for GPIO-enable fan

https://forum.doozan.com/read.php?2,12096,35663#msg-35663

So you would echo a 0 or 1 to clear or set GPIO 13 to see if Orange LED is off/on (if GPIO is ACTIVE_HIGH then 0 would clear it).

@bodhi
I will get onto this Saturday, work is very inconsiderate of my time allocation sometimes :-)

@bodhi
I have removed the gpio-leds section altogether from the dts the listed pin 13 wasn't doing anything and besides for now I don't care about the leds.

I have also removed the gpio-fans section which I tested one pin entry at a time but in all cases the fans (there are 3 on the rs816) still appear to function normally.

This only leaves sata pin 15 and usb pins 58 & 59 active from a debugfs dump

root@debian:~# cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-31, parent: platform/f1018100.gpio, f1018100.gpio:
 gpio-15  (pwr-sata0           ) out hi

gpiochip1: GPIOs 32-59, parent: platform/f1018140.gpio, f1018140.gpio:
 gpio-58  (usb3-vbus0          ) out hi
 gpio-59  (usb3-vbus1          ) out hi

uart1 pin19 and usb pins 26, 27 are still defined in the dts but seemingly unused, I could try deleting those sections or alternatively the pin 58, 59 sections and see which if either are actually controlling the usb's ?

Also is it safe for me to cycle the remaining pins to "1" and see if any HDD's turn up or do I need to do more than this to test effectively ?

@bodhi
I was conscious that I hadn't tried the synology-rs816-stock.dtb on linux-5.1 so gave it a try. On previous kernels this got as far as not finding the rootfs (no drives in /dev/) and dumping to an initramfs prompt.

A bit different on linux-5.1 with a very early kernel panic at

kernel BUG at drivers/irqchip/irq-armada-370-xp.c:658!

Not sure what to make of that ?

Just ran again this time with the dtb pulled from flash and we revert to the same initramfs prompt as on previous kernels.

There is something happening that I just can't see / don't understand or maybe my synology-rs816-stock.dtb had not compiled correctly I will go back and check / rebuild it.

Edit
Tried to rebuild and get a host of warnings but no errors although the following reads more like an error than a warning to me.

Richard,

It is safe to cycle the pins on your test box . Make sure you dont have any thing important on the HDDs or USB that you cannot recreate.

Many pins are “fixed” the SoC, meaning they serve some purposes that nobody changes the definition. Usually the higher MPP pins are ones assigned to SATA, USB, LEDs

And I don’t think we can use stock DTB with new kernel so no need to try fixing it!

Richard,

Good works :)

So what did you see on these disks? can you mount them, and list the content?

@bodhi
I zeroed the disks previous to trying this. I will setup some partitions now, mount, write data and report back here shortly.

And please post the entire dmesg log for this. I'd like to see the SATA ports activation by the kernel when you turn on the pins, and the command you used.

And the DTS is version 4?

v5 with the gpio led and fans removed. I posted it further up this page but re-attaching here.

Edit
Just noticed I had typo above, actual command was "out" not "on"

OK. I'll modify v5 and see if we can have a real solution.

Or perhaps I can tell what I have in mind and you try it: In version 6 of the DTS, create a new sata1 regulator using the existing sata0 regulator as the example. And use GPIO 37 for this new regulator.

@bodhi
I did as you suggested but it didn't work, maybe I missed something.
I have attached armada-385-synology-rs816-v6.dts if you could check for me please.

@bodhi
Spotted it myself 37 is in gpio1.
Will try again now

@bodhi

Hmm still no go, my new sata regulator looks like this.

reg_sata1: pwr-sata1 {
		compatible = "regulator-fixed";
		regulator-name = "pwr_en_sata1";
		regulator-min-microvolt = <12000000>;
		regulator-max-microvolt = <12000000>;
		enable-active-high;
		regulator-boot-on;
		gpio = <&gpio1 37 GPIO_ACTIVE_HIGH>;
	};

And when that didn't work I remembered some gpio alias in the stock dts so added

aliases {
		gpio0 = "/soc/internal-regs/gpio@18100";
		gpio1 = "/soc/internal-regs/gpio@18140";
	};

But that didn't help either, can you spot anything ?

Have you tried the brute force approach?

Usually at this point I pull up “dmesg -w” in one window and then run a script that sequentially activates each unassigned gpio pin in another. I can usually find the sata pwr pins based on when the dmesg output shows the drive being recognized.
