Radeon DRM Queues More Changes, RV6xx UVD For Linux 3.18
Phoronix: Radeon DRM Queues More Changes, RV6xx UVD For Linux 3.18
With the DRM merge window for drm-next now closing earlier going forward than in past kernel releases, another Radeon DRM-Next pull request was already submitted for Linux 3.18...
For regulars here, UVD isn't interesting really. As for userptr, larger coverage's needed. Given how memory management (bandwidth GPU <-> RAM, bookkeeping of allocations, fragmentation, TLB, MMU) is significant part of GPU driver correctness, performance et al. actual original content - say, analysis, synthesis, a bunch of links describing relevant stuff in detail - would be more than welcome.
Since titles are short, please, don't pad them with "queues more changes", "r600 uvd, mm/userptr" is what's of ANY interest.
UVD more important than you might think
I've got two machines I set up for friends with older/smaller CPU's that can only play 1080P HD video by using GPU acceleration. My little netbook does not HAVE video acceleration hardware, thus cna't play 1080p by any means but can play 720p when using a lightweight desktop like IceWM. I suspect there are a lot of laptops out there that have discrete graphics that can play H264 video but either can't play 1080p in CPU at all or use too much battery to do so. Hardware playback should be much more power efficient, if this was not so my camera could not play back its own video files.
