Any plan for basic mainline linux support?

Great! Except for 4K H.265 video playback, everything seems to be fine with Kernel 5.4.y.

[elatllat]

Well I'm sure there are other features missing, but it's a good base.

I think the mainline patched kernel used in LibreElec has the support for h265 decoding.

I think the mainline patched kernel used in LibreElec has the support for h265 decoding.

Earlier LE kernels did, but then it was discovered that GX and G12 (and SM1) all need slightly different HEVC implementations; similar to VP9 more is done in software than codecs like H264/MPEG2, and now the drivers are being reworked for upstream API compliance. I've currently dropped HEVC support from my patch-set completely until an updated driver and the associated firmware(s) are submitted upstream.

Does anyone use some gpio irq ?
irq meson seems to be initialized but i can't use it (kernel 5.4.10).
dmesg
[ 0.000000] irq_meson_gpio: 100 to 8 gpio interrupt mux initialized

I'll try as soon I can. Meanwhile, I saw that in your "testing" repository there is the 5.5.X mainline kernel. Is this version patched as the one in the "main" repository (linux-odroid_5:2019.12-1+202001141252)?
I'm asking because Chewitt recomends the 5.5.X against the 5.4.X because it has more functionalities

I will comment that lots of G12A/B audio changes went into Linux 5.5 so it would be a better kernel target for a desktop distro than 5.4, despite not being an LTS kernel. I've not seen any drama moving from 5.2 > 5.3 > 5.4 > 5.5-rc so I'd also advocate that you keep bumping the kernel instead of sticking to the LTS releases

.
IMHO I'd like to squeeze more features and power from my N2, which in the recent days has became my daily computer at home (multimedia, desktop pc, retrogaming and so on).
Thanks a lot to everyone for your efforts.

The testing repository has a vanilla kernel yet and I am packaging it to support DKMS, the same patch series will be applied as 5.4 once the package is built. I will let you know here when verified.

There is boot.scr instead of boot.ini, actually boot.scr is the standard script of U-boot. And my OS image does not use boot.ini, so it's normal. Doesn't it boot?

How can I edit the boot.scr file?
I need to set to false the autodectet display feature. I tried with nano, but after saving the system doesn't boot at all, like there is nothing on the sd card.

Changing boot.scr is not a good idea since it's binary format. Sorry for using another solution instead of boot.ini, you can choose the value or add the command in a file in the directory /usr/share/flash-kernel/ubootenv.d/upstream. You will be easily understand how they work, if you like to see the more commands that works for v4.9 kernel, check out the directory /usr/share/flash-kernel/ubootenv.d/4.9.y.

Code: Select all

tobetter@disco:/usr/share/flash-kernel/ubootenv.d/upstream$ ls -l
total 12
-rw-r--r-- 1 root root 125 Jan  8  2020 10-console
-rw-r--r-- 1 root root  31 Jan  8  2020 30-bootmemory
-rw-r--r-- 1 root root  48 Jan  8  2020 90-misc

Once you change the file, even you can add your own file in the directory, do run command $ sudo update-bootscript this will update /boot/boot.scr and back up the original one as /boot/boot.scr.bak. Since you must be not familiar with the way, please do back up the /boot/boot.scr somewehere you can copy back.

Please note that the 5.x kernel does not have many tweaks like v4.9 kernel, so even if you manage the value for autodetect it would not work.

Sorry...
In case it does not work, please do put the SD card to USB card reader and attach to USB host port of ODROID-N2 such that Petitboot can boot it up from USB host.

You may not have eMMC on your ODROID-N2 if you have boot the installer image without change? From the installer memory card, open the file preseed.ini and check out the bottom that sets the target installation disk. If you like to install Ubunto to uSD, you must set disk=/dev/mmcblk1 instead of disk=/dev/mmcblk0 which is default in the image. If you like to install manually, change the value of di_auto to false which is in the top of the same file.

[istanbulls]

I put emmc on odroid N2. Everything is fine now. installation in progress.

[istanbulls]

Password?

[mad_ady]

user/password are set in preseed.ini.

[istanbulls]

user/password are set in preseed.ini.

ubuntu desktop setup is over.
When the first version installation, asked me not to create a name and password.
In the second version he did not ask anything.
n2 has no emmc installed. therefore did not install, error warning.
I installed emmc on android in N2 and completed the installation.
ubuntu set up desktop emmc, didn't ask me if you want to install emmc.

Now I opened the desktop, he wants a password from me.
yes "preseed.ini" had Ubuntu Netboot Installer. but no more when the installation is finished.

[tobetter]

If you have installed without changing in preseed.ini, default account and password is odroid/odroid which is in preseed.ini. The preseed.ini is like a configuration for the installer.

Glad to know to know it works, I am wondering how long the netboot installer runs to complete the installation.

Hello,

Anyone tried to put your installation on uSD ? Because i tried on two installation went fine. But system did not boot ;-(
BTW both SD cards work with other distros without problems. And i tried both MMC and SPI switch.

I installed the minimal image of ubuntu disco on sd, and booted with spi switch on mmc. Then I installed the new kernel, the wayland support, made some adjustments to the user permission as reported above and, at least, installed the desktop package.
It booted fine.
With petitboot I dind't have a video output, but I don't know if it is a bug in the mainline kernel or is the same issue I always had with my LG lcd TV (I always need to edit the boot.ini file to manually set the screen resolution).

[Sav]

Just a suggestion: could it be more prductive to discuss in this thread only of the kernel development and open a new thread about the wayland and the desktop environment?

You were ahead of me, I was writing the same.
I fully agree with you, keep this thread for kernel features missing in the mainline and keep managing the rest somewhere else, maybe another thread of mine about Netboot installer. I am thinking of updating the thread.

FYI, I am building the Linux kernel 5.x using my Github, https://github.com/tobetter/linux/tree/stable-v5.4, and an update will be managed through my package repository. Your patches are always welcome.

So how far are we from having a minimal Linux distro that is roughly equivalent to the current official HardKernel Ubuntu (based on 4.9.x) for the N2? I run a headless server configuration with no need for graphics or audio, but would like to use the GPU via OpenCL. I'd like using the 5.4.x kernel to be as effortless as using what HK provides. And I don't want to have to be an expert in building kernels, etc.

I read through the whole thread and 3rd party news sites. I am a little bit confused regarding the state of the ODROID N2 in mainline especially with the release of linux 5.5
It would be great, if someone could summarize the current state of affairs
My plan is to run mainline archlinux arm or armbian on the odroid n2 as headless servers. Can I just use the mainline kernel packages? (tried with archlinux arm 5.4 - no boot) Are patches still required to the mainline kernel for a headless plain server setup? What about uboot or petitboot, which one should be used for this kind of setup?

[elatllat]

... confused ...

uboot + kernel from the post just before yours (patches for usb and speed).
if someone points out a concise patch for audio, h265, etc I'll add them but for now those are lost in chewitt's kodi branch.

[MoikvanDoik]

Hello everyone,
I managed to switch from 4.9 to 5.5.0 with elatllat's script. Thank you for that!
Everything I need works fine, but there a two problems.
1. output of free -m shows

Code: Select all

free -m | head -n 2
              total        used        free      shared  buff/cache   available
Mem:           3422         918        1358          51        1145        2290

So there is a bit of ram missing. I read the post of Rising_Sun, where he changed the memory value to 0xf0000000, but I don't know exactly in which file.
I have mevererics debian release since I got my N2 and changed the value in /opt/linux/arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2.dts to

Code: Select all

	memory@0 {
		device_type = "memory";
		reg = <0x0 0x0 0x0 0xf0000000>;

But nothing changed. I had a similar problem with kernel 5.4.13, but I think I could use almost 3,6 GB of ram.
2. When I reboot my device, I have to manually unplug and replug my USB-SSD to get it recognized. There are no problems with my two 10 TB HDDs. Could that be a driver issue?

Maybe someone can help
Thank you!
