- Email: soren.sandmann@gmail.com
Current status
- Targeted release: Fedora 18
- Last updated: Mon Jul 23
- Percentage of completion: 87.29%
Detailed Description
The lack of hardware acceleration for the Render extension 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 the spice libraries.
Contingency Plan
None necessary, revert to previous release behavior.
Documentation
Release Notes
- Support for Render acceleration in QXL device and driver
