17:25 <cza> hello, i was wondering if anyone could tell me what's the recommended way to hack on m1n1? im trying to add a few things to the hypervisor but im not sure what would be the fastest way to test out my changes. im looking into handling some missing system registers like PMCCNTR_EL0 (reading it gives me a sync abort), is there perhaps a way to handle that using the proxy? im not very well versed with aarch64 and apple platforms but i'm

17:29 <j`ey> cza: the apple cpu's have a non archtiectural PMU, so I guess that register just isnt there

17:29 <cza> yeah i figured that out, the esr was weird but there seems to be an apple PMU equivalent

17:29 <cza> so i wanted to somehow work around that and return the value from one of these registers

17:31 <j`ey> not sure if the proxy can handle that, but you could edit m1n1 itself to do it

17:32 <cza> is there an easy way to run the new build of m1n1 as the hypervisor?

17:32 <cza> so i can run the uefi os under the newly built hypervisor

17:33 <cza> or do i have to put it on the efi partition for stage 1 to chainload? that sounds like it will take a lot of time to test a single build

17:33 <j`ey> you can chainload m1n1 via the proxy, yeah

17:34 <j`ey> m1n1 stage1 -> proxy mode -> chainload stage2 m1n1 and then load u-boot

17:34 <cza> so the proxy mode i get by using -v boot args comes from stage 1?

17:35 <j`ey> yeah

17:36 <cza> alright, what im wondering about is after loading my new payload with newly built m1n1 and uboot how do i get this *whole thing* to run under the m1n1 i just chainloaded?

17:36 <cza> sorry if i cant explain what im talking about

17:36 <cza> but i want the newly built m1n1 to act as the hypervisor

17:37 <j`ey> cza: take a look at the proxyclient/tools/run_guest.py and proxyclient/tools/run_guest_kernel.sh scripts

17:37 <j`ey> as well as the wiki, it has some info about this

17:38 <cza> im using the run_guest.py script already, but i think im just misunderstanding the boot process

17:39 <cza> it seems to me that when i use the run_guest.py script, whatever payload i provide is what is run under the hypervisor, is that correct?

17:39 <j`ey> yep

17:40 <cza> so now, can the chainloaded m1n1 that's running under the hypervisor run as a hypervisor itself?

17:40 <cza> because if not, then any exceptions from the underlying os will be caught by stage 1 m1n1

17:40 <cza> which does not contain my changes

17:41 <j`ey> yes it can

17:41 <j`ey> if you use proxyclient/tools/chainload.py

17:42 <cza> ah, that makes a lot more sense

17:42 <cza> i knew i was doing something wrong because none of my changes were actually there

17:43 <cza> i'll give that a go, thanks!

17:43 <j`ey> if you see the output of the chainload, it should say something about being at EL2

17:45 <cza> yep that's exactly what it says after it reconnects to the proxy, thank you for that!

17:45 <cza> ill give that a go now that my code is actually being run :^)

17:46 <j`ey> is this windows or something

17:46 <cza> the thing im trying to run under m1n1? yep lol

17:47 <cza> i worked on porting a bootloader to m1 a few days ago and now i wanted to see how far windows can get

17:48 <cza> though the bootloader was light work compared to this, some minor memory related stuff + weird framebuffer format

17:48 <j`ey> https://github.com/AppleWOA

17:49 <cza> i see, someone had that idea before me, not surprised

17:49 <cza> i should give that a go, it probably can get windows way further than i'll ever do on my own, especially with no knowledge about the platform :p

17:49 <cza> thanks for the link!

18:07 <opticron> there's also this page from the project originator, but it's a bit more stale: https://github.com/amarioguy/AppleWOAProject/blob/gh-pages/index.md
