Linux KMS Mode
KMS (Kernel Mode Setting) mode is a feature where RetroArch can use the OpenGL driver outside Xorg, running straight in the virtual terminal. It is a fairly obscure feature, but very powerful in a console scenario.
To use KMS mode you need:
- Recent version of MESA (9.0+) (dev)
- libgbm 9.0+, libdrm (dev)
- Open source driver which supports KMS
- ./configure with flags "--enable-kms" and "--enable-egl"
These require a fairly up-to-date distro.
After compiling RetroArch, you should see this when running
KMS: KMS/EGL context support: yes
If KMS mode is working correctly, RetroArch should start up outside Xorg as well.
