Etnaviv, Mesa 3D and Novena (Page 1 of 2)

Hi xobs,

Thanks. Do you have any ideas about the availibility of EGL implementation, as part of the Mesa delivery? That would be awesome, as it will allow running Wayland on the top of the fully free graphics stack.

Regards.

I am not that familiar with linux graphics so that's why I am asking If i am correct to assume that for the 2d acceleration it kinda looks like this?:

GPU <> Galcore(vivante supplied gpl)(kernel) <> libdrm (with etnaviv support)(userspace) <> xserver-xorg-video-armada(with etnaviv support)(userspace)

And for 3d like this?:

GPU <> Galcore(vivante supplied gpl)(kernel) <> libdrm (with etnaviv support)(userspace) <> mesa(with etnaviv support)(userspace)

I have been looking around and saw that https://github.com/austriancoder  has been recently active with etnaviv
but I couldn't find any publicly available information about Jon Nettleton's https://github.com/linux4kix or russell king's http://ftp.arm.linux.org.uk/cgit/ progress. russel king's name has not been named by xobs or bunnie as being an participant in the current development, but he has developed a big part of the etnaviv project so that's why i named him.

What's the status of 2D acceleration?  How hard is it to enable experimentally on my own machine?

Using that config I get:

[ 11967.876] (EE) armada(0): etnaviv: unable to open: No such file or directory
[ 11967.876] (WW) armada(0): [drm] Vivante initialization failed, running unaccelerated

Seems likely that the issue is I lack https://github.com/austriancoder/linux/ … ng/etnaviv in my kernel.  Going to try playing with that.

I am now running on branch v3.19-novena-etnadrm-r3 from xobs' novena-linux git, which has etnaviv enabled as a built-in module, but I get the same error from X...

etnaviv support is definitely still a work in progress.  In particular, it fails frequently when resuming from hibernate.

I think you're still using vivante/galcore.  You'll need to edit /usr/share/X11/xorg.conf.d/60-novena.conf and uncomment these lines:

    Option "Screen"        "0"
    Option "AccelModule"   "etnadrm_gpu"

I grabbed the source package for the X11 driver, and narrowed the problem down to this line in etnadrm.c :

conn->fd = drmOpen("etnaviv", NULL);

I'm reading about drmOpen now, but I'm not really sure what's likely to be failing.

@ballanux installing just the kernel image and two xserver packages from that link worked for me, thanks!

I now get the same error as you.  etnadrm_dri is definitely a thing in that source tree, but it doesn't seem to compile to its own .so?

I'm not sure how these binaries are different from the kernel/xserver packages I was building from source.  I definitely needed both, though, since the xserver packages without the kernel clearly tried to use GPU, but then would fail and X would not start, until I installed the kernel from that link.

yes, mplayer also crashes for me, I use vlc with auto settings for video output

Anyway, I only can play videos of 720x400px or so, if its 720px vertical it gets stuck and only plays audio

Edit: if you want mplayer to work you can use the following options:

mplayer -vo x11 -fs video_file.mp4

or

mplayer -vo x11 -fs -zoom -framedrop video_file.mp4

but the last one may be dropping a lot of frames...

Also, regarding mplayer, there's some bug I have yet to track down.  mpv should work, though, and is mostly a drop-in replacement.
