wlroots 🚀 - wlroots does not appear to start nested using the wayland backend if the hardware doesn't ...

Yes. The interaction with split display/render devices is not trivial.

I think we have two solutions:

If we don't have a render node, just use the primary node. This is annoying because these are legacy for rendering operations (we'd need to handle stuff like drmAuthenticate).
Somehow detect which render node can be used with the primary node, and fallback to the surfaceless platform if none matches. Need to figure out how to share buffers with the Wayland and X11 backends when using surfaceless.

Note that in the case of qxl, Mesa will fallback to llvmpipe, so it's not going to be great in any case. At least until we have https://github.com/swaywm/wlroots/issues/2399.

We now pick the primary node when we're missing a render node. Please re-open if you can still reproduce.

Looks like I am missing something after building wlroots master?

Can you obtain debug logs?

wl_drm is missing here, this sounds like a Weston bug.

emersion on 16 Apr 2021

Odd, it happens under wayfire and gnome-shell too...

n3rdopolis on 16 Apr 2021

Maybe an issue with your GL stack then.

emersion on 16 Apr 2021

Perhaps. I'll try to reevaluate my Mesa compile options

n3rdopolis on 16 Apr 2021

You'll want to make sure Mesa advertises EGL_WL_bind_wayland_display.

emersion on 16 Apr 2021

👍1

I am building a newer mesa with

meson --buildtype=plain --prefix=$INSTALLDIR -Dgles1=enabled -Dgles2=enabled -Dplatforms=x11,wayland -Dgallium-drivers=swrast,nouveau,svga,r300,r600,radeonsi,virgl,iris,zink,tegra,swr -Ddri-drivers=r100,r200,nouveau,i915,i965 -Dosmesa=true -Dgallium-xa=true -Dgbm=true -Dshared-glapi=enabled -Dllvm=true  -Dshared-llvm=true -Dvulkan-drivers=intel,amd -Dllvm=true build

don't know what I could be missing. I wonder if it's the software gallium driver...

Logs from the outer compositor would be useful.

Ah, it uses llvmpipe, which means no hardware acceleration. It's probably pretty slow.

You may want to try to setup hardware acceleration, or to try out the new Pixman renderer we just merged in wlroots.

emersion on 17 Apr 2021

Trying the new pixman renderer and it seems to improve things for sway, not wayfire quite yet.

As far as llvmpipe goes, it seems to do the same if I set GALLIUM_DRIVER=softpipe and to swr as well... Maybe it's how I am building Mesa. Odd that the software renderers in Mesa don't support wl_drm.

And yes, hardware acceleration would be nice, but this is a Live CD, so I am trying to do my best to ensure it runs even on inferior hardware, (which is why as you may notice in the log that I pulled and build the simplekms driver)

EDIT: going to further look at my Mesa config, sway works with the Pixman renderer, Sway doesn't work with my mesa on the DRM backend, but it _does_ with the system mesa. (so I must have some mesa config option wrong, or there is some regression in Mesa somewhere)

n3rdopolis on 18 Apr 2021

Ah, I didn't realize you want llvmpipe on purpose. In general users don't want to use it but Mesa ends up selecting it anyways.

Yeah, Wayfire makes pretty heavy usage of GL, so Pixman isn't going to work there. Also wlroots can't yet run the Pixman renderer with the DRM backend, this will be resolved with https://github.com/swaywm/wlroots/pull/2700.

I've created this issue to run llvmpipe: https://github.com/swaywm/wlroots/issues/2871. This isn't trivial to fix.

👍1

wlroots does not appear to start nested using the wayland backend if the hardware doesn't support render nodes
