Comment On This Article

For those wishing to better understand more of the internal workings of Intel's i915 DRM driver that provides the kernel-side portion to their Linux graphics driver, Ben Widawsky of the Intel Open-Source Technology Center has written a great blog post that's the start of the series documenting the Global GTT.

The initial post targets the low-levels of the i915 driver and covers the Global Graphics Translation Table (GTT) that takes care of the address mapping from the GPU virtual address space to physical addresses.

For those wishing to learn more about Intel's DRM driver and graphics drivers in general, I encourage you to read Ben Widawsky's blog post.
