Testing Kernel GFX Drivers How to get drm/i915 off the number 1 spot on the kernel regression list ... 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.
