AMD Vega核心架构显卡终于要来了!AMD Linux驱动团队今天为AMDGPU开源显卡驱动发放了100多个补丁,从而提供对Vega的全面支持。
Vega核心基于全新的GFX9架构,这和Polaris GFX8架构有很大不同,因此驱动支持也要全方位更新。
据了解,Linux驱动为Vega新架构增加了大约4万行代码,从而可以支持新的BIOS界面、硬件IP、UVD 7.0视频解码器、VCE 4.0视频编码器、RadeonSI 3D、电源管理、DC显示输出、SR-IOV虚拟化等等。
值得注意的是,新驱动列出了七个不同的Vega ID(Fiji核心当时只有两个),自然对应七款不同型号,目测包括Radeon RX游戏卡、Radeon Pro专业卡、Radeon Instinct计算卡等,可谓“蜂拥而出”。
另外,新驱动还加入了七个Polaris 12 ID,对应着新的低端卡Radeon RX 550,但还没有看到Vega 11核心。
