Hi,

I'm trying to get Kodi 21 running on Gentoo in GBM mode, on an AMD GPU (Phoenix, 780M). I already have one Kodi (19 though...) running on an Intel GPU, just to boast I know a little bit what I'm doing.
Kodi opens the `/dev/dri/card0` node, gets all resolutions supported by the TV,enumerates EGL extensions, and gives up. This happens with both GL and GLES compilations.
Debug log snippets:

Any ideas?

After an evening of digging, at EGLUtils.cpp:323, eglChooseConfig() returns 0 matched configs. Makes sense that it doesn't work.
Something is very wrong with kodi + GBM + radeonsi...
