Summary

This feature adds support for the X Render Extension to the QXL paravirtualized device and to the Xorg QXL driver.

Owner

  • Name: Ssp
  • Email: soren.sandmann@gmail.com

Current status

  • Targeted release: Fedora 17
  • Last updated: Wed Sep 28
  • Percentage of completion: 5%


Detailed Description

The lack of hardware acceleration for the Render acceleration is the main source of performance problems when Fedora is used as a guest on a Fedora host.

Benefit to Fedora

This will make the Fedora experience better when it is used as a guest in a virtualized environment.

Scope

Several components are affected by this feature:

- The QXL device in Qemu must be extended to accept Render commands

- spice-server must be extended to marshall Render commands

- spice-client must be extended to draw Render commands

- The QXL X driver must be extended to generate Render commands.

How To Test

Good tests include running the cairo test suite against an X server running on the guest. Also the cairo performance test suite, the render-check program are useful.

User Experience

Fedora virtualized guests should feel more responsive.

Dependencies

Render support will need to be accepted into Qemu.

Contingency Plan

None necessary, revert to previous release behavior.
