<tsujp>
how can I install emacs devel (i.e. HEAD of master branch) on Asahi Remix? It doesn't look like there's a package for it via `dns search emacs` and I'm not familiar with any required patches for Fedora or Asahi Remix.
<tsujp>
If I can compile master as-is (just passing configure.ac flags) and it _should_ work then I'll do that
<tsujp>
also coming from macOS it is time to once again deal with unified CTRL that Microsoft started, damn them, instead of having a nice seperate super key (command) and CTRL

tsujp: dont see a reason why you couldnt just compile it
<cy8aer>
I built 29.2 with "--with-pgtk" at least and it works fine (but on Debian testing).

j`ey: i dont expect there to be a problem with a manual compile but wanted to ask just in-case
<tsujp>
i may have a look and see if nix has a packaged devel build because I _might_ try experiment with doing emacs' package management via nix (so things like ripgrep replacing grep etc.) can be more declarative but every time I touch nix it's a massive headache
<tsujp>
i also don't know how well installing nix onto fedora would play
<tsujp>
versus just git clone, ./configure.ac --flags, done

yeah nix looks ugly asf
<tsujp>
might try what i've always wanted to: using a headless microVM and having that somehow display a graphical window such that the host can interact
<tsujp>
curiously i see a bunch of articles about krunvm and what not for gaming with Steam and FEX. I don't care about playing games, and I _assume_ that the complex workarounds here (from my understanding thus far) are accomodations for the 16k page size Asahi uses versus the 4k page size games expect
<j`ey>
yup
<tsujp>
For something I am compiling myself I could likely just use crun in krun mode and do graphics _stuff_ and I have an emacs window which is executing in the microvm but which i can use in my KDE desktop environment?
<tsujp>
not sure what graphics _stuff_ is required though, all the custom mesa driver compiles and copr stuff like `asahi-krun` probably not required (16k vs 4k) so just default packages?

j`ey: it's minimal but with Pipewire, right?
<j`ey>
PaulFertser: yes, I managed to get it working a little now
<j`ey>
wpctl set-profile helped
<PaulFertser>
j`ey: I mean ALSA has no facilities for Bluetooth at all so you need either Pipewire or Pulseaudio or there's some not-super-reliable external driver for ALSA. If you're using Pipewire anyway it's natural you concentrate on controlling it with wireplumber, yes.
<PaulFertser>
I wonder if the Bluetooth profile is supposed to be switching automatically when you start recording.
<j`ey>
16:26:00 < pv[m]> Wireplumber 0.5.x always shows a source for BT headsets. It'll autoswitch to HFP if recording starts
<j`ey>
so I may have to upgrade to f40
<PaulFertser>
(from a2dp to hfp)
<PaulFertser>
I see you got real expert advice already, good :)

okay so I have a container with emacs compiled, everything works with buildah and podman (running emacs in terminal mode)... now to try the main event: running it as a GUI from within that microVM
<tsujp>
I don't know how to do that though... do I start a wayland session in the microVM or expose the hosts wayland session to the microVM?
<j`ey>
when Ive played with this, Ive done the latter.. but I always felt something was wrong with permissions

hmm, I got no idea what to do next honestly
<tsujp>
some _stuff_ with virtio but I don't know what
<j`ey>
tsujp: for sharing files?
<PaulFertser>
For getting Wayland inside VM
pb17 has joined #asahi
<PaulFertser>
I think the famous microVM gaming example is using "sommelier" for that, right?

ah maybe not virtio, virgl

Ah okay it is sommelier, a wayland compositor that delegates compositing to a host compositor

okay so slp added support for virtio-gpu to libkrun which means a virglrenderer backend can be used (for virtio-gpu) and that virtual device in the guest is what sommelier transports the API calls over in order to proxy calls from the guest microVM to the host (as far as I understand)
<tsujp>
this does require a change in virglrenderer which slp has made but which is not yet in Asahi Linux, is that right?
<tsujp>
`dnf info virglrenderer` shows version 1.0.1 and I don't see a merge request from slp's implementation (of virglrenderer) on their fork to the main repo
<tsujp>
AFAIK also this can be used without virglrenderer but at that point you'd only have software rendering in the microVM, so virglrenderer _is_ the hardware accelerated component here
<tsujp>
it's 3:35 am so im going to go to bed now and maybe get this working tomorrow since I kinda-sorta-a-little-bit understand what is going on (yet to get to mesa though, oh boy)
<PaulFertser>
You probably do not really need hw acceleration for Emacs though.

<j`ey>
yeah, just try without for now
<PaulFertser>
Also, there was that additional work to get native DRM contexts (?) forwarded over virtio.
gspbirel56 has joined #asahi
<j`ey>
I got some virtgl thing working, that seemed to help a lot when I was trying a VM with a GUI
<j`ey>
but without any extra packages, just what fedora currently has, that would probably be fine for emacs

KDDLB: I'm not sure if there is *release* that supports restoring a macOS .ipsw into an Apple Silicon Mac, it's possible you have to build it from latest git sources
<j`ey>
tpw_rules: you have a guide?
pb17 has quit [Ping timeout: 480 seconds]
<nicolas17>
I know a few years ago someone was reverse engineering that stuff and had to write his own tools, because trying to capture the USB traffic of the whole restore process (restoring with Apple Configurator) caused a ~20GB capture and Wireshark just died :D
<KDDLB>
I tried and it got stuck because it didn't see the Mac getting into Recovery mode
