Greetings,

I see the libvulkan.so.* libs now, but I don't see any sample binaries that look like Vulkan. Is there a list somewhere for all the files in vulkan-samples?

Regards

If the samples don't link with libvulkan directly, it won't get pulled
into the images. How are they loading that library, is it via dlopen()
somewhere? Invisible dlopen() dependencies typically need to be listed
explicitly in RDEPENDS.

As a quick fix, you can add vulkan-loader to the same
CORE_IMAGE_EXTRA_INSTALL list.

I have the impression that the only binary vulkan-samples installs is /usr/bin/spirv-cross . Are there other packages that install more samples?

I suppose you need to look at compile and install logs for vulkan-samples. And how the installed items get split into packages. I’m short, inspect ${WORKDIR} for it.

For the time being I use vulkan-tools so I get vulkaninfo. It fails apparently due to no appropriate driver available.

I think adding virtio-experimental to mesa may be necessary, right? Or is there another core recipse that will add mesa vulkan drivers?

As I said you need to inspect the working directory of the recipe to find out what goes where.

What are the qemu params to activate swrast vulkan driver? And do I still need mesa vulkan package? meson logs show it wasnt't compiled with vulkan-drivers.

I think swrast Vulkan driver may be a better option to start with. At least that is contained entirely in qemu guest so you won’t have to wrestle with pass through code paths to the host which are all experimental. It’s entirely uncharted waters for me as well.

Is editing meson_options.txt the recommended way to customize Mesa in Yocto?

You do, yes. It’s not qemu, it’s in Mesa. You can see the options here:

Ok, I added these two lines now to a file named virglrenderer_0.9.1.bb . Bitbake now says:

ERROR: Nothing PROVIDES 'ninja-nativevulkan-loader' (but virtual:native: ... DEPENDS on or otherwise requires it)

ERROR: Required build target 'core-image-weston' has no buildable providers.

Missing or unbuildable dependency chain was: {'core-image-weston', 'meta-extsdk-toolchain', 'qemu-helper-native', 'qemu-system-native', 'virglrenderer-native', 'ninja-nativevulkan-loader'

i guess you would also need to add venus support to virglrenderer.bb for qemu:

DEPENDS:append = "vulkan-loader vulkan-headers"

EXTRA_OEMESON += "-Dvenus-experimental=true"

but i have never tested this
