Graphics Working Group

The Graphics Working Group aims to maintain and improve the Android and Linux graphical related stacks for current and future GPUs used in modern ARM devices like smart phones, tablets and netbooks. We also work to advance the use of General Purpose computing on GPUs.

The Tech Lead is Tom Gall, and the Project Manager is James Elliott.

The team is divided into the following teams: Display, Unified Memory Management, Media and Libs and GPGPU.

Releases

The Graphics team releases both as part of the month official Linaro releases as well as pushing patches "when ready" upstream to a variety of projects or to our own software repositories. All of these actions when taken together constitute releasing software from the Linaro Graphics Working Group.

Each individual Subteam has their own accomplishments from month to month and those are listed on the various subteam pages.
