The Linux kernel has over 26 years of development, and in that time a rather large number of licenses as well as license header variants have accumulated in it. Scanners can only guess at what’s meant, and usually a significant amount of manual verification work is needed to “clear” the kernel by companies before they can use it in a product. Last year, the kernel community agreed on using the SPDX ids as a way of moving us towards being able to understand the licensing of the kernel with a “grep”. A brief overview of the state of the kernel licensing cleanup will be presented, as well as tooling available to help. Discussing the kernel subsystems that Linaro is active in, and any problems with applying the SPDX ids in files, will be the focus of the remainder of the session.

Supporting Complex MIPI DSI Bridges in a Linux systemFriday, September 24, 2021
Display interface solutions are often critical to design due a mismatch between System On Chips(SoC) and it’s associated application-specific display devices. A display interface bridge prevents this mismatch by converting...

SAN19-106 - What’s new in VIXL 2019?Friday, October 4, 2019
VIXL is a ARMv8 Runtime Code Generation Library which contains three components:
- Programmatic assemblers to generate A64, A32 or T32 code at runtime.
- Disassemblers that can print any instruction emitted by the assemblers.
- Simulator can simulate any instruction emitted by the A64 assembler on x86 and ARM platform. It is configurable, vector length for SVE, for example, and it supports register tracing during the execution.
In this talk, were going to introduce:
- What is VIXL? It is already deployed and is considered “mature”, for example, it has been adopted by Android ART compiler for its ARM backends: AArch64 and AArch32.
- CPU feature management and detection.
- New Armv8.x instructions support, e.g. BTI, PAuth, etc.
- New SVE (Scalable Vector Extension) support.
