Following a discussion about GPU and multimedia device integration, Linaro and other ARM stakeholders will be working towards a unified memory management solution for embedded systems that support multiple architectures and SoCs.
A preliminary discussion was held at the Linux Foundation's Embedded Linux Conference last week and another embedded memory management meeting will take place during the Ubuntu Developers' Summit next month in Budapest. They also plan to have another discussion in September during the Santa Rosa Linux Plumbers' Conference. As part of this special interest group, there's also a dedicated mailing list to the topic.
Additional details can be found on the Linaro Wiki for graphics and the mailing list announcement. Embedded memory management is considered a priority item for graphics along with system-wide GPU profiling and benchmarking for OpenGL ES 2.0 / compositing.
Now if only more embedded SoC vendors were concerned with providing open-source graphics driver stacks...
