High-throughput asyncrhonous driver API?

by Andrew Warkentin

I remember talk in one of the developer hangouts I was in about a proof of concept for a high-throughput asynchronous driver layer for seL4 (presumably based on notifications). Has code for this been released anywhere? I'm going to be starting on my own IPC transport layer and I want to include asynchronous message passing as an option.

Re: Reminder seL4 developer hangout

by Nataliya Korovkina

Hi all, I'd like to offer a short topic: status of Github repositories of Core Platform as well as repositories of seL4 with sel4CP support. The reason I'm asking is I'm looking to add Ultra96v2 support to sel4cp. I have added the board to sel4cp (locally), but the point is that the current seL4 branch "sel4cp-core-support" is behind the seL4 mainline, so I locally applied patches with Ultr96V2 support to the branch. Eventually, all works fine, and I don't mind having a better understanding of which repositories it's reasonable to contribute.

There is no recording, but I'm planning to put together a high-level summary and post that next week.

Yes, they clash. The audience apart from June, you, and me is distinct, though, so it shouldn't really be a problem.

OpenPower/PowerPC/ppc64le port: major concerns and obstacles

by Isaac Beckett

Hello seL4 devel! Recently I was on the developer hangout meeting and brought up a ppc port. Interest seemed low, and some even called ppc a “niche” architecture which seems unfair. There was also the much more concrete concerns of funding and overall maintenance. I believe an PPC port would be very valuable, and I plan to do a whole essay/write up of some sort, but I am also not the most familiar with the technical challenges, and could use more information on those. I do think there is definitely people who would want to run seL4 on PowerPC platforms. PowerPC is one of the few ISAs that has existing, modern hardware without closed-source binary blobs, which I believe pose a real threat to the trustworthiness of the hardware seL4 is currently capable of running on.

What sort of powerpc hardware are people using and able to develop for? I really only know of game consoles, and with the exception of the PS3, these tend to be so locked down that people don't seem to port other operating systems to them. I know that Raptor Talos workstations are quite nice and not so expensive when you compare them with the current state of RISC-V systems that are actually usable as desktops, but they are still out of reach of many hobbyists. IIRC someone (Gerwin?) recently did a breakdown of the costs of a port to a new architecture, including costs of verification. I guess the challenge is finding someone for whom that cost is well worth it. -- William ML Leslie
