Three years ago, the Intel kernel gfx driver infamously occupied the top spot on the regression list. This sordid state has massively improved thanks to a big effort over the past few years.

This talk will detail what we've all done to achieve this. Process improvements, improvements in the driver, test-suite infrastructure and new testing techniques developed to exercise specific features will all be covered. And of course a unsparing look at what didn't work out, what still needs to be improved, and the plans for the near future won't be missing, either.
