Sting boots on Qualcomm Dragonboard 410C

Big update first! We have been able to achieve Sting-based multi-CPU boot on Qualcomm Dragonboard 410C. The board in one of the first development boards based on 64-bit ARMv8 for embedded computing and IoT applications. This path-clears Sting execution on a real silicon and testifies our ability to run on all phases of validation. What next? We will try to enable different kinds of tests, hit few erratas and collect coverage data of our tests. A comprehensive report on these activities will be published in the next newsletter. Detailed bring-up report

Report: Coverage for new IP/sub-systems

We are in a constant process of adding support for new IP/system architectures and protocols to ensure maximum possible validation coverage for the target systems that we run on. This is going to be a rolling update/report in every newsletter edition.
Recently, the support for the following protocols/IPs were added in Sting - Secure Digital (SD), Multi Media Card (MMC), ARM PrimeCell DMA Controller (PL330), ARM CoreLink DMA Controller (DMA330), PCI express (based on E1000 device).
A generic device driver development model is very soon going to be presented to seamlessly support new devices/IPs in future under Sting. Stay tuned for more updates.

Update: Focused test development framework

Developing tests to accurately target a scenario in random testing can be a challenge. We have developed a test development framework called Snippets in Sting to address this issue. Using that, one can generate any test stream of operations across multiple IPs, assign the resources used by it, distribute random traffic in and around, control its scheduling etc.
This framework can be used as the de facto test development vehicle for focused scenarios like barrier litmus tests for memory ordering.
