AMD to open up graphics specs
http://www.0xdeadbeef.com/weblog/?p=302
a new road for AMD and ATI
根據這兩篇所提到,AMD決定開放前ATI的硬體規格(回朔至R500為止)給社群,使得Open Source社群可以完整使用Radeon chipset的2D/3D功能,並且所有人都可以取得完整的文件而不需受到NDA限制。
- To develop of a fully functional 2D and 3D driver that supports all of their newer radeon chipsets. This will be done in full collaboration with the open source community and will have the direct participation of hackers from companies like Red Hat and Novell.
- To release documentation that anyone can use to build and support drivers for their chips.
從這個狀況來看,一兩年內ATI的硬體在Linux下的support應該會大幅改善,考慮XBMC的Linux化,這個演進應該蠻值得期待;但是短期內因為還是只放2D規格,3D規格不知道什麼時候才放,所以這次短期內唯一意義等於只有「2D Open Source Driver支援到R500以後的硬體」而已。

過去Intel因為採行Open Source策略而受到社群大幅歡迎,現在的話AMD也跟進了,但是這兩家都存在CPU這個最大的戰略物資,這應該不是手上只有GPU的NVIDIA可以輕易跟進的。
不過除了基本教義派,我想這並不會真的提高太多ATI硬體的吸引力倒是真的…._A_

“I’d rather have a slower video card that actually works, than a fast one that doesn’t”
“That’s why nearly all Linux gamers and more than 60% of Windows gamers buy Nvidia cards. They’ve had better drivers for ages. Not open source, which disturbs some of the hardcore, but great drivers nonetheless.”
也就是說,因為東西能用、因為性能與Windows沒有落差,所以即使只有binary Driver,在Linux上目前NVIDIA的產品還是非常有吸引力;雖然包含FireGL功能在內都有開放,但是實際上ATI在Linux下的性能差距與Windows下有50%以上的落差,這當然會讓人感覺還有規格沒開出來,更別提即使在Windows底下的性能都和NVIDIA有落差。
[EDIT]
看起來AMD好像不是嘴巴說說….9/12,RV630的完整register列表文件出爐。
http://www.x.org/docs/AMD/
據稱 Novell 會在下周發表根據這些資料編寫的open source driver。
但是這些文件基本上仍然只有2D spec,沒辦法拿來寫3D加速的driver….
