LVGL is an open-source graphics library to create embedded GUI.
By its flexibility, this toolkit is well matching Oniro project's requirements to build a multiple kernel OS for IoT devices or enable interactions in a multiple devices environment.

DESCRIPTION:Igalia has been developing a new open source Mesa driver for the Raspberry Pi 4 since December 2019, and FOSDEM 2021 had a presentation with the status of the driver at that point. This talk will describe the current status of the driver, and discuss the improvements on the driver since last year presentation, focusing on all the work that was done to improve the driver performance, and a high level overview of the path that got the driver Vulkan 1.1 conformant. Finally, we will talk about future plans and how to contribute to the on-going development effort.

Then, the VKEXTcustombordercolor extension will be explained together with the problems that were found in it thanks to Mesa's Zink OpenGL-on-Vulkan driver. This lead to the creation of the complementary VKEXTbordercolorswizzle extension recently, which will be explained as well.

This lowers battery usage, improves latency and leaves the 3D engine free for clients to use. The display engines found in modern GPUs often can support this zero-copy mechanism only if the buffers have been allocated in a special fashion. However, buffers allocated this way won't be optimal for rendering, and only a handful of buffers can be directly displayed.
As a result, a trade-off between zero-copy display and optimal rendering needs to be made. The compositor is the natural place where a decision can be made, because it has a global view of all apps which need to be presented. Once the compositor has taken a decision, it needs to be communicated to the clients. The brand new linux-dmabuf feedback protocol enables this negotiation between the compositor and the clients.
If you're up for some window system integration madness, grab some popcorn and come enjoy the show!
