Ubuntu 20.10 / Debian 11 for ODROID-N2/C4/HC4

[tobetter]

Since you probably only want to switch once a new installation is less work.
The implementation of the boot is slightly different between the stock distribution and the tobetter distribution. The same difference is going to bite you if you try to build a 5.x.y kernel for the stock distribution (the DTB's are different).

Just for 5.10.y you can just use the petitboot option with the 20.04 tobetter ubuntu distribution.
Only for 5.10.y with panfrost you might prefer an upgrade to 20.10 from the tobetter 20.04.

I would make and installed package list ("apt list --installed" or "dpkg --get-selections") and an easily accessible partial backup from /etc/ and /home/. (And besides that I'd still make a complete system backup, but that should be optional).

Thanks. I decided to start new again.
/ded/watchdog is disabled on this kernel, right?
How can I enable it? CONFIG_WATCHDOG=y and CONFIG_WATCHDOG_CORE=y ?

No, WATCHDOG features are enabled already.

Code: Select all

No, WATCHDOG features are enabled already.

But /dev/watchdog isn't there. Or it is in another place?

Also if possible, please enable the "interactive" governor on the next kernel.

Looks like 'interactive' governor is removed?

Let me check the watchdog later.

If you tune ondemand it can behave similar to interactive

Odroid N2+

mesa 5:21.1.0-devel+202102141635~groovy

Reporting that lightdm display is broken, although I can log in to desktop with the right password. Gnome-shell seems to be working with occasional random log outs.

[specs]

I have the same problem wth my n2+.

This is the error message seen with dmesg:
Feb 15 21:47:00 n2plus kernel: [ 1677.520588] panfrost ffe40000.gpu: js fault, js=0, status=INSTR_INVALID_ENC, head=0x771c9c0, tail=0x771c9c0

Further like you say, lightdm is messed up, the mate-shell does not work right (xterm works though).
I tried to compare installed versions, but until now I have no clue.

I can tell it's not the kernel since I use a custom kernel before and after the upgrade:

Quick workaround
Before providing the right solution for the screen glitch after updating the latest packages, let me share a workaround to fix the issue. Please take the script below, same commands is attached as a file, and run from your ODROID-N2/C4/HC4. This script will revert the current mesa package to previous one built on 2021/Feb/11 and screen glitch won't happen. Sorry about this happens, build queue in my build server is temporary closed and recent version after 2021/Feb/12 will be removed soon.

[20210219] 5.10.16 kernel is coming

It's been long time to update new kernel version, I've pushed 5.10 kernel branch to build queue and new kernel version will be available in a couple of hours, still ARM Mali Bifrost will be supported but Panfrost won't with Ubuntu 20.04 since 20.04 package repository becomes too complicated. At some point sooner than later, the default kernel will be switched to 5.11 that I am currently preparing to publish the package.

Interesting features:

• Device tree overlay will be supported - the device tree support is limited currently but will be added more like Hardkernel's stock 4.9 kernel and will use the same instruction to choose and apply the device tree overlay blobs.

• 3.5"/3.2" small LCD device can be supported - continue to the device tree support, 3.2"/3.5" LCD product from Hardkernel can run with mainline kernel finally, more detail instruction will come later.

• ARM Mali GPU can be overclocked to 1000MHz, currently the max freq is 800MHz - some users already had tried to overclock the GPU upto 1000MHz which is 200MHz more than max currently, you can run 1000MHz if you won the silicon lottery.

• 'linux-image-5.10.0-odroid-panfrost-arm64' kernel package' is deprecated - this is for Ubuntu 20.10 users only. Since several patches for the Panfrost drivers are merged to officialy Linux 5.10 repository the same package is no longer required, I've managed a couple of packages to prevent the driver conflict between 'Bifrost' and 'Panfrost'.

• I've performed glmark2 testing with the version 2021.02 very recent version, please review the chart at the end of this post

• And several updates...

How to update the new kernel version?

Code: Select all

$ sudo apt update
$ sudo apt dist-upgrade

If you were using the kernel package linux-image-5.10.0-odroid-arm64, please follow up tese commands.
After these commands, your C4/HC4 must run as nomal except the bug from Panfrost. Also, display glitchy problem that happened a couple of days ago has been fixed by resetting the working package, mesa package won't be updated sometime untill the issue is resolved.

Code: Select all

$ sudo apt update
$ sudo apt install linux-image-5.10.0-odroid-arm64
$ sudo reboot
$ sudo apt purge linux-image-5.10.0-odroid-panfrost-arm64

More detail will be added if required and 1-2 pages will be added to https://docs.linuxfactory.or.kr/

Thanks for the new updates, it is good to see my favorite OS improve.

Some things I did not understand.
I've done the updates.

Code: Select all

apt update

For Odroid-N2Plus, do we need to uninstall panfrost !?

Code: Select all

$ sudo apt update
$ sudo apt install linux-image-5.10.0-odroid-arm64
$ sudo reboot
$ sudo apt purge linux-image-5.10.0-odroid-panfrost-arm64

How can I do this, a little tutorial would make me very happy.
I saw it somewhere on the forum and tried it, but I'll have to get lost inside the forum.

Are you using Bitfrost on 20.10?
Did you install the mesa package or it's been installed automatically?
Do you have the black screen on login screen or after login?

Change MAX_FREQ=799999987 to MAX_FREQ=1000000000 in /etc/default/gpufrequtils, and reboot it.

How can I do this, a little tutorial would make me very happy.
I saw it somewhere on the forum and tried it, but I'll have to get lost inside the forum.

{ARM Mali GPU can be overclocked to 1000MHz, currently the max freq is 800MHz - some users already had tried to overclock the GPU upto 1000MHz which is 200MHz more than max currently, you can run 1000MHz if you won the silicon lottery.}

Change MAX_FREQ=799999987 to MAX_FREQ=1000000000 in /etc/default/gpufrequtils, and reboot it.

Thanks, I made the GPU 1000mhz.

Do you have any information about the gpu governors?
For cpufreq you can use cpufreq-utils, for gpufreq for now I can write directly ot /sys but is there a common tool for the purpose?

I want to check how much power is saved by lowering the clock and setting powersaving as governor, since for my purpose the power used in idle mode is rather governing.

I've not made a tool for GPU but only create a method to change the governor and frequency using /etc/defaults/gpufrequtls since for some reson it did not work dynamically like CPU. Also the sys path for Bifrost and Panfrost are different. Please check the link for this.

Fair enough.

After tweaking a bit you will probably only set it once at boot.
I guess the only people tinkering around with it are those who want to squeeze a little extra performance out of their hardware.

It gives a bit better but not significant...
How did you compare?

glmark2-es2-wayland. Both around the 10xx mark

It's around 10xx with glmark2-es2-wayland, with 1000MHz is a bit faster but...
download/file.php?id=13648

hardinfo - GPU drawing
800Mhz 3284.78
1Ghz 3361.72
I think I'll just run 800Mhz

[specs]

When waching a movie with mpv the gpu clock hardly scales op above 250MHz on my N2.
I think that underlines I'm not much of a power user.

Only when I put an xterm on top of a (fullscreen) movie I see peaks of 800 MHz (does Linux/X11 not stack windows efficiently?).
Also when I compile a kernel in the background the GPU clock scales up.
I guess that's because the GPU is desperately trying to keep in sync while the rest of the system is loaded.

Typical readings:

Code: Select all

CPU 0-1: 1000 (1000 Mhz - 1800 MHz / conservative)
CPU 2-5: 1800 (1000 Mhz - 1800 MHz / conservative)
GPU    :  250 ( 250 Mhz -  800 MHz / simple_ondemand)
Thermalzone 0: 38.2 C
Thermalzone 1: 37.9 C

(When compiling the kernel the temperature gets higher off course.)

I use a small python script for the overview, repeatedly used with "watch".
(I know it is a only course indication, not professionally written.)

Hello @tobetter,
There are some things I don't understand or misunderstand, can you help me please.

My installation list with Netboot-Installer:
Shouldn't I install "sudo apt install linux-image-5.10.0-odroid-panfrost-arm64" anymore? Should I get this off my list?

Code: Select all

sudo apt install odroid-homecloud-display
sudo vi /etc/apt/sources.list
:% s,focal,groovy,g
:wq
sudo vi /etc/apt/sources.list.d/ppa_linuxfactory_or_kr.list
:% s,focal,groovy,g
:wq
sudo apt update
sudo apt dist-upgrade
sudo apt autoremove
sudo apt install linux-image-5.10.0-odroid-panfrost-arm64
sudo reboot
sudo apt install --reinstall odroid-alsa
sudo nano /etc/netplan/50-cloud-init.yaml
network:
  renderer: NetworkManager
  ethernets:
    eth0:
      dhcp4: true
  version: 2
sudo apt install ubuntu-desktop
sudo apt install kubuntu-desktop

Not necessary to install linux-image-5.10.0-odroid-panfrost-arm64 anymore, it won't be updated. Using the default kernel is fair enough after 5.10.16.

Thanks @tobetter,
I already tried this yesterday (that setup with netboot-instaler) and it performed very well.
But with the update, panfrost cannot be uninstalled, it gives an error.
Won't there be panfrost in your images anymore and why?
Regardless of the panfrost question, I am quite satisfied with the performance of the new version.

What error do you meet with which command?

You do not misunderstand the statement. Still Panfrost driver is there but no longer need to use separate package linux-image-5.10.0-odroid-panfrost-arm64 since every patch for Panforst is merged into single branch and it will be provided with linux-image-5.10.0-odroid-arm64.

Regardless of the panfrost question, I am quite satisfied with the performance of the new version.

Thanks.

Thanks for the answer,
English is not my native language and with Translate I might be missing or misunderstanding things.
I'm also a very rookie for Linux and software, some terms make no sense at all to mine.
I may be asking more stupid questions than this ring, I'm sorry for that already.
-------
I have 5-6 OS on my SSD and I occasionally experiment. I am trying to decide which OS is smoother and faster in daily use.
In order to get the best performance in this regard.
While installing kubuntu-desktop with Netboot-instaler, I have to upgrade to 20.10 version. Should I run the command "sudo apt install linux-image-5.10.0-odroid-panfrost-arm64" after 20.10 version upgrade- not?
Again, the same question is valid for Groovy-Gnome-Desktop.

For example, I installed Groovy-Gnome-Desktop with Netboot-instaler. During the installation I did not run the command s "sudo apt install linux-image-5.10.0-odroid-panfrost-arm64". I am very pleased with its speed and stability.

Replied the same in another thread, you do not need to install linux-image-5.10.0-odroid-panfrost-arm64 any more. But still you will have Panfrost driver with linux-image-5.10.0-odroid-arm64.

[chewitt]

This solves the GPU governor issue: https://github.com/chewitt/linux/commit ... 8ac2a5deb4

it should be partnered with this: https://github.com/chewitt/linux/commit ... 399ce43d12

both should be merged in Linux 5.12

[20210223] New kernel 5.11 is coming

New kernel 5.11 is uploaded and default kernel will be switched on coming weekend hopefully.

** BUT DO NOT UPDATE WITH THE NEW KERNEL 5.11 IF YOU ARE RUNNING DESKTOP WITH PANFROST DRIVER **
It's because we had bad experience of broken UI issue about 10 days ago and desktop UI had many issues, therefore old version of Mesa package had been uploaded that works with Linux kernel 5.10.16 today. New kernel 5.11 also requires another compatible Mesa package which is not incompatible with 5.10 kernel, this makes us keep using 5.11+ kernel once new mesa package is uploaded for Linux kernel 5.11, this would be ok if 5.11 kernel does not make critical issues.

In case if you like to install new kernel 5.11 with new packages, please do follow up the commands below at your own risk.

Code: Select all

$ echo "deb http://ppa.linuxfactory.or.kr groovy testing" | sudo tee -a /etc/apt/sources.list.d/ppa_linuxfactory_or_kr.list
$ sudo apt update
$ sudo apt dist-upgrade
$ sudo sed -i "/testing/d" /etc/apt/sources.list.d/ppa_linuxfactory_or_kr.list
$ sudo reboot

EDIT:
For ARM Mali Bifrost users: 5.11 has a change that cannot build DKMS packages which breaks to build Mali Bifrost driver package mali-bifrost-dkms, still figuring out to make it work and will come with official kernel switch to 5.11.
