Hi. New here. I know microphone support for M1 Max mbps is WIP - but where? I'm not sure which repo to look. Looking to see if I can lend a hand in some awy.

ariejan: As I understand the main problem is not the microphone hardware support itself but the beam forming stuff. And in this channel chaos_princess talked about it some month ago.

<chadmed>
the beamforming and noise cancellation stuff is a pain
<chadmed>
there is no sane way to replicate what coreaudio has for that in linux without more stupid custom plugins
<chadmed>
its also unclear how the microphone array is actually supposed to work. there are three mics in the laptops but two of them seem acoustically coupled to the chassis or something
<nickchan>
measured cpu frequency reached 2508 MHz
<nickchan>
using modified proxyclient/experiments/cpu_pstates.py
<nickchan>
the register that corellium called CLUSTER_PSINFO1_GET() and CLUSTER_PSINFO2_GET() in linux-m1
<nickchan>
that register (at a different offset) on a10 seems to be writable
<nickchan>
which allows arbitrary changes in meaning of the pstates
<nickchan>
so like what frequency and voltage pstate N is
<nickchan>
in the example above I am modifying the definition of pstate 1
<nickchan>
so yeah that's an overclock primitive
<nickchan>
on a10 the cpu ratio is (((psinfo1 & 0xffffffff) >> 0xe) & 7) / 5 + ((psinfo1 >> 4) & 0xff) / ((psinfo1 & 0xf) * 2 + 2)
<nickchan>
haven't figured other fields and psinfo2 yet but presumable has to do with core and sram voltage
<nickchan>
the cpu ratio is multiplied with the 24 MHz clock to get the final frequency

<nickchan>
not sure if they are locked down on m1
<nickchan>
a safe test would be to say, overwrite the definition of pstate 3 with defintion of pstate 4
<nickchan>
and see if those states are the same now

<ariejan>
cy8aer thanks for the update. I'll try to find it in the logs.
<nickchan>
though i must say that state is very unstable
<nickchan>
probably because i didn't mess with the other fields
<m3thos>
talking about generic x86 windows application support, that woud be very much appreciated. there are a bunch of applications (closed source) that aren't released for linux-arm64, for example: Slack, Zoom, Discord
<chaos_princess>
all of those are electron wrappers, just use the web version

they're not entirely equivalent with the web version
<nickchan>
something like 2400 MHz is a lot more stable though
