Server KMS Drivers


Servers generally ship with fairly simple GPU hardware that can provide scanout and a small amount of VRAM. Currently we use drivers to drive these chipsets. However a set of simple KMS drivers could be written along with a single driver to drive this hardware. Bringing the featureset of KMS to these chipsets.

Detailed Description

Chipsets such as MGA based serverengines and AST chipsets are mainly found in servers, providing KMS drivers for these allows consolidation of userspace and kernel drivers across desktop and servers.

Benefit to Fedora

Going forward we only want to support kernel modesetting based drivers instead of legacy user modesetting drivers. It also allows a single userspace driver to drive these chipsets generically.


Develop a kernel modesetting driver for MGA G200SE chipsets based on driver. Develop a kernel modesetting driver for AST chipsets based on driver. Develop a userspace generic KMS driver to drive these chipsets unaccelerated. (Possibly develop an XGI KMS driver for Z7/Z9).

How To Test

Have server hardware with MGA SE, AST or XGI hardware. Desktop variants may not be suitable. Install system and see if the installer works and if the console and desktop work post install.

User Experience


kernel changes. changes.

Contingency Plan

Do nothing, stay as we are now.


Release Notes

Server chipset drivers are moved into the kernel for better future support.
