Odroid C2 mainline kernel support

[moon.linux]

Hi All,

We all know Odroid C2 support is being initialized in mainline kernel.
I would like to share the process of build and install the kernel so that developers could contribute to the mainline kernel.

Amlogic have different variant of development boards and rich feature sets of devices.
Hardkernel Odroid C2 is one of the device that have Amlogic S905 ARM 64 bit boards.

Here is the development link of the driver that have being merged http://linux-meson.com/doku.php

List of patches that are being considered. https://patchwork.kernel.org/project/li ... ogic/list/ for merge

So Here is the steps to compile the build and test Linux mainline kernel.

Code: Select all

odroid@odroid64:~$ cd /usr/src/
odroid@odroid64:/usr/src$ git clone  git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git odroidc2-4.y-final


Build the kernel for ARM64 we have currently use defconfig
odroid@odroid64:/usr/src/odroidc2-4.y-final$ cat build_kernelc2.sh

Code: Select all

#Build the kernel using odroidc2 defconfig
#make mrproper
make defconfig
make -j4 dtbs Image modules LOCALVERSION=-xmlc2
make modules_install LOCALVERSION=-xmlc2
mkimage -A arm64 -O linux -T kernel -C none -a 0x1080000 -e 0x1080000 -n linux-next -d arch/arm64/boot/Image uImage

Install the kernel into /media/boot partition

odroid@odroid64:/usr/src/odroidc2-4.y-final$ cat installc2.sh

Code: Select all

#/bin/bash
set +x
kernelversion=`cat ./include/config/kernel.release`
cp -v .config /boot/config-$kernelversion
echo "kernel version" $kernelversion
cp -v ./arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dtb /media/boot/meson-gxbb-odroidc2-$kernelversion.dtb
cp -v ./uImage /media/boot/uImage-$kernelversion
cp -v .config /media/boot/config-$kernelversion
sync
#reboot

To test the board is booting on to mainline kernel. We need to stop at the bootlooder prompt and manually start the kernel.
Note: This is testing for new kernel.

Here are the command for testing.

Code: Select all

setenv bootargs "console=ttyAML0,115200"
setenv dtb_mem_addr "0x1000000"
fatload mmc 0:1 $dtb_mem_addr meson-gxbb-odroidc2-4.7.0-xmlc2.dtb
fatload mmc 0:1 0x01080000 uImage-4.7.0-xmlc2
bootm 0x1080000 - $dtb_mem_addr


Note: We can append these command into boot.ini but still some driver are missing to initilaize the mmc an emmc so the rootfs is not getting started.

Code: Select all

Please let us know if their is some driver we could port and contribute to mainline kernel.

[crossover]

Seems to be very relevant to this thread.
viewtopic.php?f=138&t=20869

Anyway if the SD/eMMC and Gbit Ethernet works stably, we can use the Kernel 4.7 for many headless applications at least.

[moon.linux]

Sorry I did not now about other thread.

Great that TFTP boot is working well it's make development process much easy.
Thanks you very much. I will give this a try.

[brad]

To test the board is booting on to mainline kernel. We need to stop at the bootlooder prompt and manually start the kernel.
Note: This is testing for new kernel.

Here are the command for testing.

Very nice you have the 4.x kernel booting from the standard hardkernel u-boot using bootm! I have been trying for a while now and failed to overcome the segmentation fault. Appears you have aligned everything in memory to work correctly and boot using bootm

[moon.linux]

I am just closely following your other thread to make the kernel boot up. You have also done some excellent job in sharing your work.

[swiftmas]

Oh wow, so once tested this will be the new standard kernel for the C2? I know right now it is on 3.14LTS I think.

[endecotp]

Oh wow, so once tested this will be the new standard kernel for the C2?

No. It has only a few of the required drivers - nothing at all related to graphics, for example.

[swiftmas]

(#noobmoment) dang wishful thinking.

[afremont]

Do you know if amlogic plans to support version 4?

This is the one thing that I dislike about these SBC platforms, manufacturers want to keep everything a secret. I long for the days when manufacturers documented everything and publicized it.

I really don't see the threat from people simply knowing how to use the capabilities of their systems. It doesn't seem to me that it would make it easier to produce knockoffs, from people knowing how to use the parts.

Anyone desperate enough can reverse engineer the code from an end product. In fact, that's how many things are done in the Linux world, or at least used to be. I suspect that still applies.

I'm of the opinion that if manufacturer fully opened up on a chipset, that they'd gain a lot of marketshare. Take ARM for example. They opened up and now virtually dominate the market.

[moon.linux]

Amlogic Kernel maintainer Carlo Caione (carlo at caione.org) and Kevin Hilman (khilman @ baylibre.com) could share us more in sites on the future plans.

But this gives developers excellent change to understand the protocol and reverse engineer the drivers and help build test and kernel.
Mainline kernel development is pretty slow we need to keep track on patches from developers for particular Arch. http://lists.infradead.org/mailman/list ... ux-amlogic Mailing list.

I would like to see developers contributing to the mainline kernel and help build this product.

[Raybuntu]

I don't think any drivers need to be reverse engineered. All drivers are already there and released as GPL. Amlogic is just doing things differently and not the "proper" way. I guess a lot would help if Amlogic would give public access to their git.
They are releasing their code without any git commit history.

I have a few points to get things rolling...

What have I tested successfully running various versions of 4.7...

- Ethernet (possible issues with gigabit Ethernet driver - workaround is to use a 100Mib switch)
- Kernel compilations with no problems. CPU temps stayed low & no problems maxing out 4 cpus. Same thing with an attempted compile of gcc 6.1, system was loaded for 6 hours straight before compile error on 3rd stage.
- Testing with root filesystem mounted from NFS & also sdcard (with early development driver)
- Openssl benchmarks and comparisons - both kernels perform approximately equal and both can take advantage of the neon instructions in the cpu's.
- CRC32 optional driver for arm64 is present in the 4.7 kernel but I dont believe it is in hardkernel (I need to check this)
- Hardkernel Ubuntu image boots with minimal fuss for a headless setup and others have reported the basic odroidian image working as well
- Console support via UART - make sure its enabled under character device drivers and also console support, no need to pass kernel parameters at boot
- Enabling debug, kernel tests and trace modules. (For large kernels you may need to move the uInitrd to load from a higher address, ive successfully booted 80Mb+ kernels with the uInitrd loaded into uboot at around 0x26000000)
- Native kernel builds on the c2 with gcc lincaro 4.9 & 5.3

Problems
- current u-boot im using is providing random mac address on boot and I get a new IP when rebooting
- Ubuntu resolv is not working so have to manually add the nameservers to the resolver configs

What I want to test....
- Realtime kernel build
- emmc card
- different frequency scaling and governor modes for the cpus and different scheduler setups
- Different memory settings and configurations
- Gigabit ethernet
- SPDIF driver
- random number generator
- cross compile on a x64 using various versions of linaro (4.9, 5.3 & 6.1)
- Native build on c2 using native gcc 6.1 (I haven't been able to build it successfully yet)

What else to test?
- IR driver
- watchdog

My current wishlist ...
- USB and regulator support via 1 of the controllers
- Basic HDMI support
- Audio support DIN & DOUT and analog dma support
- amlogic s905 crypto driver

[umiddelb]

Which patches should I apply against mainline in order to get the eMMC/µSD and eth0 up an running?

[kodiakfi]

I don't have anything useful to add on the technical front as an end user but I wanted to thank everyone who is working on mainline support. I dream of the day I can run Fedora 25 on the C2 unmodified.

[umiddelb]

KH's latest kernel boots up fine now (eth0 doesn't need to be bound to 100MB/s any more).

[korken]

For the uninitiated, what are the improvements for switching to the mainline kernel?

[moon.linux]

Stability, Efficiency and tons of features which keep on improving day by day.

Can I just use current odroibian build and compile the 4.7 from there? will that work?

Is usb working?
Thank you

Sure you can. But alot is still not working.

4.7 - USB is not working, SD-card or eMMC is not working. just cpu boot and network filesystem.
next: 4.8 - SD-card and (maybe) eMMC support is added. still no USB.

@KARL23 this is very nice.

is HDMI working? what about GPIOs?

And most important - what u-boot are you using?

Thanks!

A working mainline kernel is there:

I must be missing something about this build or installing this kernel. I pulled the zip file down from github, did the make defconfig, etc...
Applied the patch though most of what was listed here: viewtopic.php?f=135&t=22717#p152487
does not need to be done any more. It built clean..
Try to boot it off my 64gb eMMC with no luck, even tried the manual steps listed by moon.linux above.
Noticed it was still trying to read: meson64_odroidc2.dtb so copied meson-gxbb-odroidc2-4.8.0-rc2-xmlc2.dtb over to that file

Hi,

you can build a working kernel using my repo:

Code: Select all

#!/bin/sh
set -ex
# git clone --depth 1 --single-branch -b v4.7/integ git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git
git clone --depth 1 --single-branch -b c2 https://github.com/ioft/linux/
cd linux
make odroidc2_defconfig
make clean
make -j 4 Image dtbs modules
sudo rm -rf /boot/kernel.d/test
sudo mkdir -p /boot/kernel.d/test
sudo cp System.map arch/arm64/boot/dts/amlogic/*.dtb /boot/kernel.d/test
sudo mkimage -A arm64 -O linux -T kernel -C none -a 0x1080000 -e 0x1080000 -n linux-4.7.0+ -d arch/arm64/boot/Image /boot/kernel.d/test/uImage
sudo cp .config /boot/kernel.d/test/config
sudo make modules_install
sudo make firmware_install
sudo make headers_install INSTALL_HDR_PATH=/usr
kver=`make kernelrelease`
cd /boot
sudo rm -f config-${kver}
sudo rm -f initrd.img--${kver}
sudo ln -s kernel.d/test/config config-${kver}
sudo update-initramfs -c -k ${kver}
sudo mkimage -A arm64 -O linux -T ramdisk -a 0x0 -e 0x0 -n initrd.img-${kver} -d initrd.img-${kver} uInitrd-${kver}
sudo mv initrd.img-${kver} kernel.d/test
sudo mv uInitrd-${kver} kernel.d/test/uInitrd
sudo rm config-${kver}


At the end you will find the kernel image, initrd image, dtbs etc. in /boot/kernel.d/test (Instead of compiling you can download the kernel here as well). You need to copy these files to /media/boot if you are using the standard/default HK boot procedure.

You can use the HK firmware (BL2 Built : 11:44:26, Nov 25 2015 / bl30: amlogic_v1.1.3046-00db630 2015-10-28 15:24:31 / BL3-1: v1.0(debug):4d2e34d, BL3-1: Built : 17:08:35, Oct 29 2015 / U-Boot 2015.01-00126-g8171a45 (Jun 15 2016 - 18:32:37)) to boot the mainline kernel, but you need to modify some boot parameters:

• The serial console is called `ttyAML0` instead of `ttyS0` (that might explain why you cannot see anything else after 'Starting kernel ...')
• The dtb file name is `meson-gxbb-odroidc2.dtb`instead of `meson64_odroidc2.dtb`
• /dev/mmcblk0 is uSD, /dev/mmcblk1 is eMMC
• The kernel has to be started via `bootm` therefore the image must be an uImage

Cheers

Hm, the onboard ethernet devices hangs/freezes without further notice starting at a bandwidth of 25k/s. I suppose, that I need to use a different firmware which does a proper hw initialization, see here.

[bleedingedge]

Have anyone tried 4.8-rc4 ?
Does that mean we will have ubuntu 16.10 with 4.8 kernel working ?

[BlueMatt]

Did that patch fix it for you? Previously, if your forced the eth into 100M mode (or connected to another side that only supports 100M) it would work fine.

Not really, even if I issue

Code: Select all

sudo sudo ethtool -s eth0 speed 100 duplex full autoneg on

I'll get these hangs/freezes as well. I might consider to use your patched mainline u-boot instead of the HK u-boot.

USB isn't fully supported in the 4.8 kernel:

Code: Select all

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M


Whereas the HK 3.14.77 kernel shows:

Code: Select all

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M


[umiddelb]

If I use a recent mainline u-boot version to boot this kernel, the internal USB Hub is discovered (unfortunately non of the connected USB devices).

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

Unfortunately the network frezzes/timeouts are the same here as well (even with 100 Mbit/s speed).

Is it possible for you to try to enable the following in the kernel config and recompile..

Under Networking support > Networking options

IP: kernel level autoconfiguration
IP: DHCP support

They need to be built in and so do the network drivers rather than as modules. Configuring the network this way (and early in boot) seems stable for me at 100Mit (4.6,4.7 & 4.8). I still cannot get it working at Gigabit speeds.

I found an issue with the resolver when you boot this way and DNS stops working. I needed to manually a name-server to the resolver config to get dns back, although I suspect there is a better way.

USB isn't fully supported in the 4.8 kernel:

There are some USB patches floating around these days..see https://patchwork.kernel.org/project/linux-clk/list/?submitter=38211, mostly.

[mlinuxguy]

On the other thread about No performance difference between 1.5, 1.75 & 2GHz
I was discussing testing the L2 cache on the upstream kernel (perhaps offsetting any possible DDR3 tunings we might have to do)
I went through the L2 arm64 cache patch series up to this upstream kernel and it appears to actually get a working L2 cache
we need entries like this in the appropriate DTS file: meson-gxbb.dtsi

Code: Select all

        cpu@0 {
            device_type = "cpu";
            compatible = "arm,cortex-a53","arm,armv8";
            reg = <0x0 0x0>;
            enable-method = "psci";
            next-level-cache = <&A53_L2>;  <--- sets up the cache
            timer=<&timer_f>;
        };
...
        A53_L2: l2-cache1 {
            compatible = "cache";
        };

This would be similar to what they add via patches for cache support in new arm64 boards
Didn't find that in ours...

Great!
Did you boot from SD? or eMMC?
How about Gbit Ethernet connection?

BTW, Brian.Kim told me he could enable the USB host port on C2 Kernel 4.8.
Ask him a simple patch.

[moon.linux]

Some patches are still under review for USB PHY. Ethernet is not working effectively I saw some kernel panic with iperf testing.
I booted from SD card for now just for testing.

[brad]

I see Brian has submitted some patches to enable usb for upstream I appreciate the work from Brian / Hardkernel on this and would be more than happy to perform any testing if required

[kxv]

The S905 SoC has gained more support in Linux 4.9.
See http://lkml.iu.edu/hypermail/linux/kern ... 03429.html .

[rgadsdon]

I have managed to find a (nasty!) hack to fix the long-standing Ethernet hang/freeze problem (Kernel 4.9-rc1 patched)

Reduce speed to 100Mbps and turn off flow control..

Code: Select all

# ethtool -s eth0 speed 100 duplex full autoneg off

More info at http://rglinuxtech.com/?p=1831

Robert Gadsdon. October 21, 2016.

[alpha_one_x86]

Yes but it's at 100Mbps...
CVE-2016-5195 it's another reason to have mainline kernel support. To have quickly the security fixes.

EDIT: With autoneg=off it's 35Mbps, mean 3MB/s, then clearly less than the 100Mbps...

[nobe]

this 1Gb bug might be fixed in mainline thx to jerome brunet
there is a patch attached here : http://lists.infradead.org/pipermail/li ... 01538.html
note : it needs to be cleaned at line 99, i guess a comment was badly suppressed

i'd like to test it myself but unfortunately i'm unable to boot successfully all the kernels i cross-compiled
i've tried different kernels : mainline 4.8, mainline 4.9-rc3 & khilman v4.10/integ

everything seems to be working fine : the kernel starts correctly but always hangs after detecting my sd-card

are you guys booting from sd, emmc or tftp ?

[brad]

Be careful as arm firmware now allows 2gh processor speed but if not restricted will often crash new kernel during boot. In my case when initing the emnc clocks. Use the max freq kernel param same as current kernel or an old version of uboot limited to 1.5g

[nobe]

i still use the u-boot provided by hardkernel, so i guess i should be ok

but i can try this max freq kernel param you're talking of
should i just append something like "cpufreq.scaling_max_freq=1520000" to the bootarg variable in the boot.ini file ?

edit:
ok, i got it wrong, it should be "max_freq=1536000" or "max_freq=1536", i have to make sure of this :p

[brad]

i still use the u-boot provided by hardkernel, so i guess i should be ok

but i can try this max freq kernel param you're talking of
should i just append something like "cpufreq.scaling_max_freq=1520000" to the bootarg variable in the boot.ini file ?

The latest hardkernel uboot includes new arm firmware which allows 2GHz and the new kernel (non hardkernel) now has frequency scaling at on boot and goes off and uses full power if it wants. Its not even actually uboot but the first stage arm firmware provided that boots the uboot that allows this.

im not near my c2 at the moment and not 100% sure this will work but does this kernel boot arg help?

max_freq=1520

just add it to the bootargs parameter, but cant be sure it will work for non hardkernel kernel but bets are on from my limited access to resources at the moment

[nobe]

thx brad

just for the reference since i misleaded you : it's "max_freq=1536"
see https://github.com/mdrjr/c2_bootini/blo ... t.ini#L126

i'll try this in the afternoon then i'll report success or failure

edit:
it still fails to boot

here is the boot log :

and there it hangs

[brad]

and there it hangs

I experienced the same thing a while back and as quick fix I reverted to old arm firmware to restrict to 1.5G. (In my case when it froze I had stall detection enabled in the kernel and the console showed me a cpu got stuck due to the overclocking and an illegal instructions). I will try to find a workaround for newer firmware to restrict cpufreq.

When the ethernet patch will be integrated to the mainline?
