driver stack

Phoronix: "Intel's Linux graphics driver stack is often at the forefront of X.Org / Mesa innovations, from Intel being the first driver having in-kernel video memory management to being the first driver with mainline kernel mode-setting support to even being the driver that often first receives support for new OpenGL extensions in Mesa."

Phoronix: "... but AMD is putting forth its own notable effort as well. They have multiple full time employees working on open-source support and have released specifications and programming documentation for their entire range of chips.

The past few months have seen a flurry of activity in graphics related development, and a fair amount of this is centered around AMD hardware."

Phoronix: "We had found that using some of the latest kernel code had improved the performance some, but still there were major regressions within Intel's new Linux driver stack."
