Dear seL4 friends, With the great success of the seL4 summit 2022 behind us, we are now already looking at the seL4 summit 2023! This should happen around Sep/Oct 2023. We have started investigating options for the location, and we would like your feedback. We would very much appreciate if you could fill in this very short survey to tell us your opinion between USA (likely Minneapolis) and Australia (likely Sydney) or any other feedback you have: https://forms.gle/k4XxYaYeudYUie9U8 <https:… [View More]

Experimental project on seL4 microbenchmarking
by Nataliya Korovkina 20 Nov '22

20 Nov '22

Hi seL4 friends, I’d like to share an experimental project on seL4 microbenchmarking inspired with my experience with sel4bench suite. Your thoughts on the concept and its practical use will be greatly appreciated. Motivation (informal) Measuring execution times of short code paths, which we can meet in seL4 microbenchmarking, is a good way to immerse oneself into the domain of compiler and microarchitectural optimizations. Implementation of “early processing” measurement methodology in … [View More]

Cross Core IPC
by Sid Agrawal 24 Oct '22

24 Oct '22

Hi, I came across Gernot Heiser's blog post on "How to use seL4 IPC" [1]. The article explicitly says that doing cross-core IPC is a bad idea. This statement led to a series of questions for me, which I hope you guys can help me with. Scenario ------------ We have a system with two cores. Let's say that a physical memory server is running on core0, my application is on core1, and they are somehow pinned to those cores. The application wants some physical memory (frame capabilities) from the … [View More]

Suitability for a project
by James Hillman 19 Oct '22

19 Oct '22

Hi Sel4 developers, I am new to this forum and hoping this is the right place to bounce my project idea off. I typically use FPGA to enforce security in my products but there are lots of reasons why FPGAs are not suitable for all use cases. I have also used low end microcontroller where one can review all the code to understand the security risks. My latest project however involves two USB processes (one for each physical connection) with high throughput expectations. And to pass data streams … [View More]

I was interested to see the Google news re. KataOS which I suspect confirms that my sort of requirement / entry point is someway out. I was also reading about ARM Morello / CHERI work. Although I appreciate this is taking a different, perhaps flawed, path of some new hardware memory protection. Appreciate any feedback you can humour me with.
