Phoronix: Re-Introducing GEM-Free UMS Support In The Intel Driver
It seems like it was just yesterday, but Intel introduced the Graphics Execution Manager more than two years after they had a falling out with TTM. In switching over to using GEM for their in-kernel video memory management, and subsequently supporting kernel mode-setting and then introducing UXA to GEM-ify the EXA 2D acceleration architecture, there was a lot of problems. Fortunately, most of these problems were worked out as this more advanced Intel Linux driver stack matured and for the better part of a year now the experience has been pleasant for users of most Intel GMA chipsets...
