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.

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.
