 Posted: Wed Aug 18, 2021 9:15 pm Post subject: RPI4 arm64 xfce slow and sticky v4c with high CPU usage of X |
 |
|
Ok i went ahead and installed arm64 on rpi4 modelB 4G.
Everything was easy.
I used makeoptions 4 and still everything was ok.
It boots fine into xfce.
But i have a problem i suppose with the vc4 driver.
Plz first have a look at my emerge --info

The issue is i keep having a constant 40% cpu usage from X.
This doesnt happen with my Devuan arm64 installation.
By the way I used the above to chroot into Gentoo when I was building the system.

I created an initrd with dracut.
I dont know if it is necessary but i assumed a kind of copy-paste approach from Devuan to Gentoo.
I have linux-firmware-installed
I moved my / on mini ssd and it works just fine.
I installed the contenets of /boot by cloning
https://github.com/raspberrypi/firmware
My dmesg
https://pastebin.com/3S0qxSsw
My rc.log
https://pastebin.com/3epyZL4c
I have "libinput" in input_devices in make.conf.Is it ok?
Your precious wisdom would really be very very welcome.
Thanks a lot Guys.

I FOUND IT!!!
In make.conf
VIDEO_CARDS="v4c v3d"
That is I appended v3d.
Now it works flawlessly.
Still wifi is giving me trouble though....

I connected an ethernet cable so wifi became insignificant.
BUT now i see there is NO binary web browser for arm?
Oh my!!!
What am i supposed to do now?
Build one on a pi?

alamahant,
Cheat. Feel free to use my arm64 binhost.
The Pi4 is no too bad a build system.
-- edit --
The wifi chip and its firmware is intended to with with EFI firmware, which the PI does not have.
You need the .txt file to provide the data that the EFI firmware would provide.
-- edit --
Built on a Mudan arm64 server, with 8 cores and 128G RAM ...
| Code: | Mon Aug 16 12:51:33 2021 >>> www-client/firefox-91.0
merge time: 3 hours, 40 minutes and 54 seconds. |

Everything seems perfect now if not for a new slight glitch.
Although cpu usage is reasonable both when playing youtube and vlc 15-40%(i am satisfied with this number.In other arms i had 100-200%),there is a slight pause sometimes like its buffering.Not only youtube but also vlc.
I have cpupower installed and running with "--governor performance" and also rng-tools.
What would be causing this occasional stutter when playing video?
Is there any way to remedy this?
Thanks again....
