Panfrost Status on Odroid N2

[jonathon]

Knowing this it would be nice to have a systemd unit file that does the change for us on system startup:

As an alternative, systemd-tmpfilesd provides another approach:

Code: Select all

$ cat /etc/tmpfiles.d/set-gpu-min-freq.conf
w /sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/min_freq  - - - - 799999987

This will write the value on boot.

You can also check for supported frequencies over here:

Code: Select all

$ cat /sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/available_frequencies 
124999998 249999996 285714281 399999994 499999992 666666656 799999987

Not sure if this is useful at all but I was curious to measure current panfrost performance (mesa from git) when running GL applications on XFCE and Gnome. I ran glmark2 first 4 tests (glmark2 segfaults after this because of a glmark or panfrost bug) so here is the chart I generated on LibreOffice after running glmark2 on each environment:


Note: this is using the performance governor

It shows Gnome running on both Wayland and X11 and one can see that Wayland offers better performance for GL applications on this environment. Meanwhile, with XFCE I ran also the test twice, one with compositing enabled and the other with compositing disabled and results with compositing disabled are really nice, everything feels snappier without compositing and the supported GL applications run better, so at least these results are concrete and not just placebo effect

[jgmdev]

For those that haven't noticed yet, if enabling layers.acceleration.force-enabled on firefox to get better rendering performance notice that this option will cause panfrost to stall and system unresponsiveness after opening more than 1 tab. This unresponsiveness doesn't always happens immediately, depends on the content been rendered.

[jgmdev]

Latest mesa from master is doing improper color mixing for videos. On archlinux I reverted to the mesa-arm-git package from this commit ef06f1bb03c and videos work correctly.

[jgmdev]

The improper video color mixing is fixed now and some other good news from our friend at phoronix:

@jgmdev

Do you have a guide (link) for setting up Panfrost with xcfe?

@jgmdev

Do you have a guide (link) for setting up Panfrost with xcfe?

All you need is an updated kernel with panfrost patches and updated mesa preferrably from latest work on master/git.

Kernel:
https://github.com/tobetter/linux/tree/ ... y-panfrost
https://github.com/chewitt/linux/tree/amlogic-5.10.y

Here is an update to the not so scientific testing of panfrost using glmark2, but now also including wayfire and a fresh build of mesa from master git (commit: 67de6356f84):



1. There is a significant performance boost when running wayfire which is a wlroots based compositor, which seems to indicate that wlroot compositors are the best option for panfrost now.

2. XFCE without compositing seems to have regressed and also while doing the test noticed that with the recent mesa build the default compositing of xfwm4 which uses glx doesn't works properly so to fix it I used xpresent xfconf-query -c xfwm4 -p /general/vblank_mode -s xpresent, the positive news is that now xfce with xpresent compositing is faster than running without compositing.

3. Gnome seems to have stayed almost the same with a little bit of more frames per seconds for both X11 and Wayland, and wayland still offering better performance on this desktop environment.

[jgmdev]

Got curious with previous results and added sway to the mix, the numbers on wayfire are still better but sway is pretty close been both wlroots based.

Thats really great news. I just fired up my n2+ yesterday and tried newest mesa-git with amlogic 5.11 kernel and was disappointed by opengl 2.1 showing up. Thanks for keeping the arch repository uptodate, it really helps testing things.

[cdu13a]

[Edit: I made a bit of an oops, and posted the wrong results for the N2. I have edited the post to correct this.]

While still a long way to go before matching the binary blob for performance. It's still great to see amazing progress on features.

For those interested in a comparison of N2 (Mali G52) vs C4 (Mali G31) using Panfrost with just drm/gbm.

Desktop OpenGL 3.1 on Mali GPUs with Panfrost:

[odroid]

I know well it is still very early stage. But I want to hear about Vulkan API implementation.
Is there any news about Vulkan support from Panfrost?

[chewitt]

The devloper "Icecream95" started work on a vulkan driver a few months ago but work is currently paused while some required/enabling work on the scheduler takes place. I believe the scheduler things are now done or at the point where things can move forwards again, so hopefully the vulkan effort will resume soon.

See: https://gitlab.freedesktop.org/icecream ... commits/vk

Panfrost developers enabled GL3 by default for Bifrost !

This is a bit of a dream come true.
