Quite a lot has made its way into the Linux 2.6.31 kernel, particularly Radeon kernel mode-setting
and the new TTM
GPU memory manager, but now the merge window for this release cycle is closing. Linus Torvalds last night released Linux 2.6.31-rc1 as the first test release of this new code. Besides the new graphics work within the Direct Rendering Manager side, this kernel boasts various new drivers, enhancements to other drivers, and updates to existing file-systems.
While not pushed within the merge window, Linus hopes to still merge the SCore architecture and a few other changes into Linux 2.6.31.
