https://lwn.net/Articles/822521/
Covering patches used in the Android Common tree to provide partial cache flushes for DMA-BUFs, and what issues and blockers need to be resolved for this functionality to move upstream.
Major new features since last year's LPC include
- RAW capture
- GStreamer element
- V4L2 compatibility layer (allowing V4L2 application to use libcamera transparently through LD_PRELOAD)
- Support for new platforms
- Raspberry Pi (with a fully open-source implementation of the image processing algorithms)
- i.MX7
We have continued working on the Android HAL implementation...

Despite having capabilities to specify access control at a high level of granularity, SEPolicy is typically added in the development process as an afterthought; to accord the same permissions to a given set of processes that were developed with no regard to access restrictions. On Android - where SEPolicy operates in mandatory access control (MAC) mode - OEMs typically rely on tools such as...
