Open-Source Radeon Tries Again For PCI-E 2.0
Phoronix: Open-Source Radeon Tries Again For PCI-E 2.0
David Airlie sent in some PCI Express 2.0 patches for the Linux kernel DRM this morning, which will hopefully allow supported Radeon graphics cards to run at PCI-E 2.0 speeds by default...
PCIE3 isn't needed for graphics yet anyway
Once the OpenCL code is running full speed it will become more important to get that supported, but it's not an urgent need yet. Better to focus on other performance optimizations and power management for now.
PCIE2 was needed badly, so this is good news.
