we only care about the beta problem until the next macOS release, which is imminent I think
<marcan>
the RC is out, right?
<marcan>
so this will stop being a problem very soon
<marcan>
in the meantime, using the beta with kmutil to run stuff isn't a problem in practice

Will the Linux userspace eventually load from the internal SSD, or will it always require an external USB drive?

M1f4a9[m]: there is nothing preventing booting from the SSD other than having the right drivers

Great, I was worried there would be some security measures preventing it
<M1f4a9[m]>
I guess I'll buy the maxed out Mac Mini with a 2TB SSD then

jannau: I tried the corellium kernel on my macbook air (8 core GPU; 16 GB RAM) and it hangs at reboot with the message: Starting linux loader stub.\nLoader complete, relocating kernel...
<sven>
m1n1 won't boot the corellium kernel without some modification fwiw

sven: ~.
<sven>
it's still early for this whole project. give it a few weeks :)
<Glanzmann>
sven: Sorry, macbook was sleeping. I assume that the Asahi kernel has soon all the drivers that the corellium kernel has and than I'm happy to run the asahi kernel.
<Glanzmann>
sven: Yes, I got it. However I'm eager to try it out and I'm happy with assembling the vdmtool.
<Glanzmann>
Also I look forward to try the pongoos bootloader.
<sven>
eventually everything will be in the upstream kernel anyway :)
<sven>
if you want to try out the corellium kernel it's best to stick to their tooling for now.
<Glanzmann>
Got it, but it doesn't seem to work on the macbook air anyway.

At least not on my. I updated macos 11.2 and execute the shell script, no luck yet.

Glanzmann: the shell script from their blog post seems to fetch a fixed and old linux.macho (loader and kernel binary)
<jannau>
use this one: https://downloads.corellium.info/linux.macho either by replacing the URL in the script or by downloading it manually and just executing just the kmutil configure-boot command from the script

I see. I'll try it now.

jannau: That worked. Not much use yet, because I'm out of USB ports. But it boots up, I have X, smp appears to be working. If the system would load into RAM, I could have put an ethernet card.
<Glanzmann>
and plugged an apple usb-c adapter instead of the keyboard and now I have network.
<Glanzmann>
Tried to play a video with mpv using the frambuffer, which worked but utilizing 8 cores half.
<Glanzmann>
Benchmarked the RAM speed which was 20 GB/s read using sysbench. Comparable with the previous topline ryzen generation. The new ryzen deliveres 30 GB/s.
<Glanzmann>
4k video drops frames. But works as well.
<jannau>
macos is on my mac mini approximately factor two faster for multithreaded AV1 decoding using dav1d
<jannau>
decoding without rendering that is
<Glanzmann>
I see.
<jannau>
hw-virtualised linux under macos is roughly the same speed as native macos.
<Glanzmann>
Wow. I see. jannau What do you use? paralles or the hypervisor that ships with macos?
<ar>
Glanzmann: just wondering, what sysbench options did you use?
<Glanzmann>
jannau: Can you walk me through your setup, I would like to try that. Especially if I get a fullscreen X so that I can use my linux custom key binding for fvwm2 ....
<ar>
Glanzmann: ryzen 4750U with these options gets: 131072.00 MiB transferred (14859.37 MiB/sec)
