[NOTES] Multi Core support

[Giovanni]

Not really, the ARM port already runs on Cortex-A, it is a good solution.

Hi,

Just my 2 cents.
Software running on hi-end cores would run Linux, Android, Windows,....to benefit from existing softwares, packages, stacks,...
ChibiOs, any other RT kernel, would run on the Cortex-M cores to handle ..... the real time stuff

So, for these kind of devices and OSes, there is a need of IKSP, inter-kernel support package.

An IKSP is a nice idea.

There is space for an RTOS IMHO for applications like hypervisors and trust zone, Linux and the rest would run in a VM. You could have Linux and a realtime VM with RTOS.

Update, the change is mostly complete in the RT7 branch.

Now I need to set up a platform for testing, a dual Cortex-Ax or Cortex-R52 or dual PowerPC.

What was the outcome of all this? Any plans to merge this into master? Any official Cortex-R support in ChibiOS?

[Giovanni]

Hi,

Not yet but it will happen, basically it is the existing ARM port with minor improvements.

Multi core in RT7 is mostly done, I am waiting for a suitable platform to test it.

ChibiOS already supports Cortex-A and I have already MP1 boards. Cortex-A is not really a focus for ChibiOS, you want to run Linux on something like that, this is why I am not pushing on the MP1.

L5, W and newer H7s have higher priority.

ST Stellar MCU was announced only 11 months ago and it's complete silence since?

[Giovanni]

That is the R52 I was referring to...

I am involved on Stellar development, I can't disclose details but it is alive and well, it will be awesome

C'mon, can you say anything? 2020 availability or 2023? flying lead packages or only BGA?

[Giovanni]

Packages are under discussion, cannot comment, sorry.

Personally I would like to see multiple options.
