analoq, probably. kernel side GPU stuff is very much in the reverse engineering phase at the moment, so there is at best just a framebuffer, no acceleration.
<alyssa>
marcan: how'd you get macOS to do a linear framebuffer with DCP?
<roxfan>
iboot prepares one iirc

iboot has a special interface I thought
<marcan>
alyssa: mouse cursor
<alyssa>
marcan: got it.
<alyssa>
meanwhile I got baby's first DCP crash
<pipcet[m]>
out of curiosity, how are you interfacing with the DCP? m1n1 or linux?
yashi is now known as analoq
<analoq>
Graypup_: thanks
<alyssa>
pipcet[m]: m1n1 right now
<alyssa>
Trying to get dcp.py in 4k
<sorear>
analoq: video decoding is not part of what is being discussed as "gpu"
<pipcet[m]>
alyssa: awesome! I might have to get a mini after all :P

Do we know what codecs the M1 supports natively?
<rowang077[m]>
* Do we know what codecs the M1 supports native decode/encode for?
<analoq>
sorear: good to know. But still it looks like support isn't quite there yet to be able to use one as an htpc/nas/server :D

<rowang077[m]> "Do we know what codecs the M1 su" <- I know they are 8. Writing GPU drivers should allow to interact with them.
<alyssa>
no?

hmmm, I copied my /System/Library/Kernels/kernel.release.t8101 and Im now running it with run_guest, but I just get the coloured apple logo and nothing on the uart :(
<j_ey>
hm, maybe I have updated my main macOS install since I made the linux partition

j_ey: I had a similar issue, it was because my kernel cache and my macos install were of different versions. I updated the wiki with details for reference to help duplicate: https://github.com/AsahiLinux/docs/wiki/SW:Hypervisor I tested it with macos 11.5.2
<landscape15[m]>
So you have to update also the firmware files in the Asahi Container?
<jeffmiw>
but I had things on the uart showing some macos panic. did you check the baudrate ?
<jeffmiw>
landscape15[m]yes
<j_ey>
jeffmiw: I set it to 11520
<j_ey>
115200
<landscape15[m]>
Ok get it.
<j_ey>
I'll try and get the kernelcache from m1n1s partition later
<jeffmiw>
j_ey: this is what I have benn using 115200 8N1
<sven>
did you open the secondary usb interface?
<sven>
and baudrate etc. shouldn't matter there
<j_ey>
yes picocom /dev/ttyACM1
<sven>
hm.. that should work
<jeffmiw>
if you only see the coloured apple logo and no progress bar you are vey early in the process
<sven>
you can also try to break the run_guest.py script and look at the backtrace to see where it's suck
<j_ey>
I didnt think to try bt, but it was weird because p.hv_translate(hv.ctx.elr) gave me 0x0
<j_ey>
wait I dont have symbols, so bt wnt help
<sven>
that sounds very broken
<sven>
you can always reverse engineer what's going on ;)
<sven>
seriously though, some functions are rather obvious
<j_ey>
I'll start by trying to get the 'right' kernelcache anyway, hopefully that just works(tm)
<jeffmiw>
you may want to check the ttyACM : if I restart the MBA M1 but the previous run_guest is still open, the USB interface will be allocated to ACM1 & 2
<j_ey>
I've been careful with that
<j_ey>
should probably setup a udev rule
<jeffmiw>
I have a config working so if you still have issue after using the right kernel cache, we can compare to figure out what is different on your side, let me know
