Developer meeting / doing kernel in C

Hi everyone , I have been busy with browser stuff. So that’s why I haven’t posted here for a while.

Last night I started to tinker with the RPCemu code on Genode aarch64. I figured out that the SWI system in RISC OS can easily be adopted to run Genode code. Which means that I can have “module” features running in Genode. Hijacking a SWI call is easy, but injecting code/data into RISC OS is more dificult.

The plan is to move HAL to Genode. I also need shared memory, not relying on a emulator to read write.

The goal is to have a completely transparant system, whith fast cpu emulation. It needs to keep 100% compatibily with current RISC OS.

Regarding RISC OS on Linux:
I think it is great, but not exactly what I want. In theory my work can be adopted to run with Linux as kernel instead of Genode base-hw.

If you want to talk about that I think a better way is the Linux Port. A total makeover is really a lot of work a splinters scarce time and resources

If going to aarch64 , things needs to be changed. If not ,a complete emulation is needed. Running RISC OS on top of Genode is currently my own leisure project. It isn’t someone elses roadmap and I don’t get paid for it. No one is forced to like it! :D

It’s always better when people have fun doing what they do.
I find more is achieved that way.

If you can get paid for the outcome, that’s a bonus. It should never dictate the requirement.

But if you’re using QEMU on the port, then performance might suffer and RO might not be so fast as it is on ARM.

Michael Grunditz, are you familiar with Gerph’s Pyromaniac project, which I think aims towards something similar? (At least in the sense of intercepting SWI calls to allow RISC OS programs to run in a new environment.)

I wasn’t aware of pyromaniac! Looks very interesting! Absolutely fantastic!

Amazing, it should’ve be named PINE (PINE Is Not an Emulator anyone?) because it’s some sort of RISCcy WINE

(PINE Is Not an Emulator anyone?)

But the P would stand for Pyromaniac and that breaks the recursion.

How about PING? – (Pyromaniac Is Not GNU)

The recording of Gerph talking about it at ROUGOL is here – https://youtu.be/YBtVgvJNeNQ

And at the following month’s meeting he showed it running the WIMP. Not very usefully, because sprites aren’t implemented yet, but still amazing to see it functioning at all!

I suggest a meeting first weekend of february.
Saturday 6/2. We need someone who can host it.

I’m curious to know whether the suggested video meeting went ahead, and if so, was there any particular outcome(s) from the meeting?

I am also curious. Did this go ahead?
