Curious about the top contributors to the open-source Intel Linux kernel driver, Ben Widawsky of Intel's Open-Source Technology Center did some analysis.
When looking at the total lines of code counted within the latest Intel Linux DRM driver, Jesse Barnes was the top Intel contributor with more than 16,255 lines of code. Following Jesse were Chris Wilson and Daniel Vetter with each above ten thousand lines of code in the mainline kernel driver.
This analysis though is only counting the Intel i915 DRM driver and not Intel's DDX/X.Org driver, their Mesa i915/i965 DRI drivers, or other Linux graphics components. For those wishing to find out more of Widawsky's analysis, read his blog post
