Detailed Description

The current spice GPU driver for Linux guests is an X.org only driver. A kernel modesetting driver needs to be developed along with a new X.org driver that runs on top of it.

Benefit to Fedora

Fedora acts closer to native hardware inside spice VMs.

Scope

Develop a basic modesetting driver for QXL GPU Develop an acceleration/memory management interface for QXL GPU. Develop a new X.org driver on top of the new interfaces.

How To Test

Test inside a virtual machine with QXL support. plymouth should show up along with smooth booting. X should work as usual.

User Experience

There should be no regressions from the non kms driver experience.

If the qxl module isn't loaded (compiled out or forced not to load via kernel command line) driver should work as usual without kms.

Older drivers will not be supported when kms module is loaded. Fedora will update the kernel side by side with xf86-video-qxl so this won't be a problem.

Dependencies

kernel changes - drivers/gpu/drm/qxl X.org changes - updated xf86-video-qxl

Contingency Plan

Do nothing, stay as we are now.
