Intel Working On TTM Integration For Discrete vRAM Management

More than a decade ago when the open-source graphics driver stack was being modernized with kernel mode-setting and better handling the stack for OpenGL, composited desktops and the like, TTM (Translation Table Maps) was born for managing GPU video RAM by the kernel Direct Rendering Manager drivers. While Intel initially expressed interest in TTM, they ultimately decided to create GEM as the Graphics Execution Manager for handling their video memory management needs. Now in 2021 with Intel aggressively pursuing discrete graphics, they are working on TTM support.

Fortunately, now there is a happy next chapter to the CUPS printing story.
