This is a KMS driver for Matrox G200 chips. It supports the original
MGA G200 desktop chips and the server variants. It requires 0.3.0
of the modesetting userspace driver, and a version of mga driver
that will fail on KMS enabled devices.

bool "Disable Write Combine mapping of VRAM"
depends on DRM_MGAG200 && PREEMPT_RT
help
The VRAM of the G200 is mapped with Write-Combine to improve
performances. This can interfere with real-time tasks; even if they
are running on other CPU cores than the graphics output.
Enable this option only if you run realtime tasks on a server with a
Matrox G200.
