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.

Bug fixing and other quality&stability efforts in 2012, features implemented and merged, quick overview of Haswell hardware and a look forward to what's in the pipeline for 2013 ...

This talk covers the desing of dma_buf as merged into Linux Kernel 3.3 and deep-dives into some of the technical issues that make buffer sharing non-trivial. It will also explore what's definitely still missing and look at what crazy stuff still might come to dma_buf in future.
