Hello,

 

I'm porting one of my application to Armbian. But where can I found libkms ?

I did a apt-cache search but it didn't found anything ?

 

Thanks

If it is not provided by upstream (Debian or Ubuntu to say) you may need to build it on your own.

Well, it is supposed to be part of libdrm but has been disabled as per a ticket I found.

The only examples I found to directly use Linux' frame buffer using DRM use it to retrieve display geometry and bitmap

 

you can use https://github.com/Caesar-github/libdrm-rockchip/tree/rockchip-2.4.101-2-ubuntu18.04 as an example;

copy the libkms entry from debian/control over to the libdrm sources, set libkms=true in  debian/rules, add dh_makeshlibs -plibkms1 -V'libkms1 (>= 2.4.89)' -- -c4 to rules after override_dh_makeshlibs.

 

 

ok, thanks : I'll try.

As I would avoid to force users to recompile system's packages, I patched my framework as well to fall back to framebuffer as well.

Retropie has a fork (https://github.com/RetroPie/mesa-drm) which builds libkms for this purpose.
