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.
