>Any methodology I could help contribute on?

Several people have already contacted me today with this request. This is how I give out details and share current progress with you.

Yes, you can help, most people on HN could. It is not that difficult work and it is not just low level debugging, coding and FPGA hardware. It is also organizing and even simple sales, talking to funders. With patience, you could even get paid to help.

>any place you have your current progress written up on?

Not any place in public, because of its value for zero-day exploits. This knowledge is worth millions.

I'm in the process of rewriting my three scientific papers on reverse engineering Apple Silicon low level instructions.

>it seems vague with how far people have currently gotten and exact issues.

Yes, I'm afraid you're right, my apologies. It's very much detailed and technical stuff, some of it under patent and NDA, some even sensitive for winning economic wars and ongoing wars (you can guess those are exiting stories). It even plays a role in the $52.7 billion US, €43 billion EU and $150 billion (unconfirmed) Chinese Chips Acts. Apple Silicon is the main reason TSMC opened a US factory [1], keeping its instruction set details secret is deemed important.

If you want more information, you should join our offline video discussions for more info. Maybe sometimes sign an NDA for the juicy bits.

While understanding the GPU’s microarchitecture might be useful for exploits it’s definitely not worth “millions”.

You are right. The zero-day exploits might be worth roughly a million each, but not the family tree of native GPU's, ANE, CPU instruction sets and microarchitecture on which they would be based.

My apology for writing unclearly, English is not my native language. I'm surprised it is yours.

Saving on energy, programming effort and purchase cost of a supercomputer in case of M4 instruction sets and microarchitecture knowledge would also save millions.

I doubt that, largely because nobody is really using Apple silicon for supercomputing efforts.
