Sorry, but the bar for adding recipes to oe-core is higher than a single 
all-purpose word 'useful'. Useful to whom? What does the tool do? Is it 
essential for making an embedded system? You really should write a 
(much) longer commit message, for a start.

Well it is sort of an equivalent of glxgears for checking whether or not 
GBM-based rendering actually works. We have piglit for testing, eglinfo 
for getting information about the EGL & GLES support, and kmscube also 
adds a visual output to see that rendering actually behaves nicely.

I am also using kmscube to test/debug mesa on our boards. i am also in
favor of having the recipe in oe-core, for the reason stated above.

[PATCH v2] kmscube: add recipe

[Carlos Rafael Giani]

This is a demo application that draws a three-dimensional spinning cube
using EGL on top of KMS, via Mesa's GBM library. A rough counterpart to
glxgears, it is a useful tool for BSP makers to try the 3D rendering
functionality based on EGL and OpenGL ES in a KMS environment, without
having to set up Wayland or X11.

It is also interesting for Yocto-based  projects that do not need any
windowing environment and instead render their visual output fullscreen
to KMS directly, since they can use it as a reference.

This is much better, but will have to wait until after 2.3 is out.

FWIW, I tested this recipe on Dragonboard 410c and 820c, with a newer
upstream commit compared to what you have in this version:

-SRCREV = "e56980c28766ffb0bf8edee96b529a5b47f97137"
+SRCREV = "0d8de4ce3a03f36af1817f9b0586d132ad2c5d2e"

it worked fine, including for video mode using Gstreamer and h/w video
codecs (vl42)

thanks for the recipe!
