NicoD Posted December 23, 2019 Posted December 23, 2019 Hi all. I've been working with the OPi3 and PineH64 model B the last days to try installing MESA and DRM drivers to make Panfrost work. This doesn't seem to work. Every time I install Mesa and reboot. It boots into the desktop normally, but a few seconds later the screen goes into one color. Everything is unresponsive. Can't go to a terminal window. Numlock is stuck... Just tried again with compositor disabled. It does take a bit longer before it blocks. But it still happens about a minute in every time. I can't find a ttl adapter for better debugging. I'll order new ones. Both the OPi3 (bionic 5.4) and PineH64(bionic 5.3) have the same issue. I'm using self built images. You can try it with the script here Don't install all, only install mesa and drm. It seems to install well, but after reboot everything is broken. Any clue would help. Cheers. 0 Quote
NicoD Posted December 23, 2019 Author Posted December 23, 2019 Panfrost does work on the H6. Except for hanging the system. I was able to start supertuxkart to see it's using panfrost. And then the system crashed. This time just showing what was on the screen instead of one color, but still crashed fully. I'm sick of it. I have no idea what I could do. 0 Quote
@lex Posted December 27, 2019 Posted December 27, 2019 I have been told LE 9.8.8 has panfrost working smooth , i think it's a @jernej's work. (not sure) I have no idea how to fetch this version and have a look at panfrost diff. Maybe you can. In my experience i have applied all available patches and still not stable enough. 0 Quote

NicoD Posted February 18, 2020 Author Posted February 18, 2020 I'm still getting nowhere with it. After installing panfrost onto Armbian Bionic and reboot I get this result. (OPi3) I think I'll throw in the towel. If anyone fas more succes then I have, please let me know. 1 Quote
JORGETECH Posted March 12, 2020 Posted March 12, 2020 @NicoD How did you even got Panfrost to work? I am trying your script in the Orange Pi Lite 2 using Armbian Ubuntu Bionic (kernel 5.5.8) and I can't get glxinfo to recognize the Mesa Panfrost driver, it still says it's using llvmpipe. Is there anything else I'm missing, like special Xorg configuration? 0 Quote

ning Posted March 12, 2020 Posted March 12, 2020 if you use wayland session, panfrost is used by default. if you use Xorg, a config file is required, which is same as lima. please follow: https://gitlab.freedesktop.org/lima/web and make sure your xorg >= 1.20 2 Quote
ning Posted March 12, 2020 Posted March 12, 2020 if you use ubuntu, don't build mesa your self, you can use https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers if you insist to build your self, please also update libdrm and libglvnd. these two deps are also important. 3 Quote

I thought that the problem lied in the DTS/DTSI files because the GPU and Display Engine have a line saying "status = disabled" which lead me to believe they were disabled due to instability (it may have a different meaning, correct me if I'm wrong). However, I don't know if that's true since I compiled LibreELEC for the Orange Pi Lite 2 successfully and Panfrost just works with the 5.5.6 Linux kernel, which means that the problem may lie elsewhere (I think LibreELEC uses GBM for the display rendering though, not X11). Maybe @jernej can give a better answer.

I tried making a custom Xorg file as described in that wiki, but it still uses llvmpipe for both GL and GLES. Also,I don't know what to put in the "MatchDriver" field since sun4i-drm seems to be related to older AllWinner SoCs (H6 is sun50i).

No, they are disabled because nobody took time to properly enable them in board DTS until now (it will be in 5.7). 26 minutes ago, JORGETECH said: sun4i-drm seems to be related to older AllWinner SoCs (H6 is sun50i). No, sun4i-drm is for all Allwinner SoCs, it supports Display Engine 1.0, 2.0 and 3.0. It's just named by Linux tradition where it takes name of first (oldest) supported platform. 3 Quote

Ok, now I understand better how hardware is defined in DTS files. I realized the Orange Pi Lite 2 DTS is really barebones compared to the Orange Pi 3. I can wait for kernel 5.7 to test more. The question I have is: How does it work in LibreELEC if the same DTS is used? (Is it only needed for X11 acceleration?) EDIT: I answered my own question. The LibreELEC pull request for Orange Pi Lite 2 (which I merged on my local repository) adds the GPU and Display Engine entries in the DTS. So Armbian would need to merge that in the first place, @Igor can you take a look at the commits from this pull request (if you have the time of course)?, it has both the GPU and DE added to the DTS unlike Armbian's one. I would do it myself but I fear I would break the working patch since I have to learn more about git and diff. EDIT: I enabled the gpu myself but I found the system to be unstable after doing that, I will try to debug it with UART (SSH crashes too) and report back.

As always, thanks for the useful advice and answers. 2 Quote
JORGETECH Posted March 21, 2020 Posted March 21, 2020 With a serial to USB converter I got some logs of the crash, it actually provokes a kernel panic. It doesn't always immediately crash but I can see screen corruption. Should I send the logs to kernel devs or Mesa devs? opilite2_panfrost_crash.txt 0 Quote

JORGETECH Posted March 23, 2020 Posted March 23, 2020 (edited) I examined @AndreBotelho's DTB and it's not really much different from the DTB I'm already using, so I don't think it would change anything. However, patches like this could help, I think I should wait first for the Armbian patches to be adapted for 5.6 kernel and then continue testing. Forget it, it's already been merged, but I still have my doubts over the posted DTB. Edited March 23, 2020 by JORGETECH Correction 1 Quote

Like I said it just a quick fix while it is not merged, I've built Armbian from source and the hdmi still is not working with default DTB so using Libreelec source( works but buggy) I've changed some options on the DTB( I'm not expert). It appears that the hang is beeing caused by the GPU clock table and the dummy clock driver from Panfrost and the HDMI missing sound and resolutions is due to some bug on voltage source option. 1 Quote

Myy Posted April 7, 2020 Posted April 7, 2020 Looks like some memory unit not prepared correctly, based on the first faults. Did you try showing this to the folks at irc://#panfrost@irc.freenode.net ? 0 Quote
Werner Posted April 8, 2020 Posted April 8, 2020 Not yet. However I answered to the already existing issue report from @NicoD at https://gitlab.freedesktop.org/panfrost/linux/-/issues/2 0 Quote
Myy Posted April 8, 2020 Posted April 8, 2020 Do you have the entire dmesg that comes with it ? Maybe there's some message like a broken MMU or IOMMU. Or some other messages that might indicate that the problem is not directly within panfrost. Also, did you try this patch : https://github.com/jernejsk/LibreELEC.tv/blob/linux56/packages/linux/patches/amlogic/amlogic-0001-FROMLIST-drm-panfrost-Don-t-try-to-map-on-error-faul.patch This might just crash the driver earlier though. EDIT : The patch is actually mainlined. Here's the commit (and patch) : https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/panfrost/panfrost_mmu.c?id=eb9d8ddbc107d02e489681f9dcbf93949e1a99a4 0 Quote
Werner Posted April 8, 2020 Posted April 8, 2020 Aight, this is what I've got so far: It seems like Panfrost does not like to be run on dvfs. Put the gpu governor to userspace and fix its frequency. This way it will run halfway stable. It still throws some errors to the dmesg but at least it does not crash. Heatsink is mandatory! 0 Quote
Werner Posted April 8, 2020 Posted April 8, 2020 They are still there. But it is not crashing any more. 0 Quote
