12:16 <maxg_> Hi, where does one get started on reverse engineering parts like the touch id hardware? I read trough the wiki where I found descriptions of how things work on the apple silicon systems, I did not find information about which tools/processes are used to conduct this kind of development tho, I would appreciate some starting point on where I can read up on those things. I assume this question has been answered a lot of times

12:16 <maxg_> so if you could just point me to such an answer

12:18 <j`ey> maxg_: m1n1 is the main tool you will use

12:23 <j`ey> there's a bunch of experiments in proxyclient/experiments where you can took a look at how it works

12:27 <maxg_> Ah, so I need to get started by using the proxy mode, then analyze what macOS is doing is what I assume? Thank you, proxyclient/experiments is an ideal starting point

12:28 <j`ey> yup

12:28 <j`ey> you can trace macOS

12:29 <j`ey> (to trace macOS you need a separate macOS install to run it over)

12:46 <maxg_> Okay so I was going trough this special macOS install documentation and I see "Install m1n1 as custom boot object", this build/m1n1.bin file, do I provide it to 1tr using some kind of removable storage or how?

12:47 <j`ey> just on the macOS file system somewhere

13:42 <janneg> I usually use `python -m http.server --directory build` on my dev system and `curl -O dev:8000/m1n1.bin` in 1tr

13:44 <j`ey> (oh woops, I misread that, didnt see the '1tr' in the question)

14:45 <roxfan> what's SDSB mentioned here? https://github.com/AsahiLinux/docs/wiki/HW%3AApple-Instructions

14:48 <roxfan> i guess some kind of barrier but what?

14:58 <sven> looks like something that was left over in some xnu or llvm strings or source code

14:58 <sven> we probably only know the name

15:21 <roxfan> huh

15:32 <sven> it might from that weird XNU source drop where they included llvm bitcode instead of compiled object files

15:33 <sven> there's "mild_dsb_enabled" in there

15:33 <sven> maybe it's that?

15:33 <sven> roxfan: ^--

15:34 <roxfan> hmm
