Real Time kernel is out of linux kernel upstream for long time. It keep contributing much of key features into upstream, like high resolution timer, lockdep, thread irq, PI, ftrace, etc. The Linux foundation setup a group to merge it all into upstream. This session is going to review RT requirements, the block issue in upstream kernel, and the solution to fix them in RT. We also go through the current out of upstream RT code. Introduce the base stone of RT features: sleeping spin_lock. This session also covers the basic criteria of RT, the general testing tools.

In areas such as automotive where faulty software could lead to a risk to human safety, software development is often covered by functional safety standards such as ISO 26262. The Development tools used to produce software are themselves complex pieces of software that are far from bug free. In the worst case a development tool can silently inject a fault into the output of its customer's software or give false assurances by failing to detect a diagnoseable error in the input. The functional safety standards used in these markets require the developer's tool choice and specific usage of it to be justified against a standard risk assessment schema, a process known as 'qualification'. In this presentation I will present: - Introduction to functional safety concepts - How these are applied to development tools - ARM's experience in producing the ARM Compiler Qualification Kit and how we adapted it to cover components derived from open source. The content assumes no prior knowledge of functional safety, the technical focus is on development process.

The ACPI PM domain supports the so called direct_complete path during system sleep in a way to avoid wasting power, but also to decrease the system suspend/resume time. However, the direct_complete path has limitations and doesn’t perform well in all scenarios. The so called, runtime PM centric path, often offers a better option. This session compares the two concepts and gives an update on the related work for ACPI PM domain.

Building a totally secure boot system goes through establishing a full trust relationship among all the different involved software layers, to prevent execution of unauthorized software. Doing that by implementing a complete Chain Of Trust based on existing industry standards and open source software guarantees interoperability, stability and easy maintainability. This presentation will describe how this goal can be achieved on ARM systems from the very first firmware executed at power-on up to the Operating System execution by combining ARM Trusted Firmware with EDK2, two reference open-source implementations of the ARM Trusted Board Boot Requirement and UEFI Secure Boot specifications respectively.
