## Feature Matrix for radeonhd
**This page is only for free [[radeonhd|radeonhd]] driver.**
**See [[RadeonFeature|RadeonFeature]] for radeon (xf86-video-ati). THIS PAGE IS NOT FOR [[FGLRX/CATALYST|ATIProprietaryDriver]] DRIVERS PROVIDED BY AMD/ATI.**
Also check out the [[RadeonProgram|RadeonProgram]], [[GalliumStatus|GalliumStatus]], and [[ATIRadeon|http://dri.freedesktop.org/wiki/ATIRadeon]] at DRI wiki.
* "**DONE**" means that it is implemented and relatively bug-free.
* "**MOSTLY**" means that it is implemented but has some known bugs.
* "**WIP**" means that someone has started on the initial implementation.
* "**BIOS**" means only if supported by your BIOS. No software support. Yet.
* "**SLOW**" means that the feature is implemented and bug-free, but slow. Improvements may or may not be planned.
* "**STALLED**" means that whatever code has been written is accumulating color and texture similar to that 3 week old slice of pizza in your fridge.
* "**N/A**" means that the feature is not supported by the hardware.
* "**N/N**" means that the feature will not be implemented, because a better alternative is or will be available.
* "**TODO**" means that someone needs to write the code. The required knowledge to write the code may or may not be known. Please ask on #radeon/#radeonhd if you want to get your feet wet on this.
* "**UNKNOWN**" means that the current status of this item isn't known. You are free to update it if you know. [[!table header="no" class="mointable" data="""
