how to use: grab sptm, txm and a kernelcache. they're all in the preboot volume or just use ipsw extract --sptm and --kernel and then python3 proxyclient/tools/run_guest.py -l m4_`date +%Y%m%d-%H%M%S`.log --sptm-mode=emulation --sptm m4pro_sptm.b --txm m4pro_txm.b m4pro_kernelcache.b -S […]

(Almost) all of that is upstream in m1n1 now which means that our hypervisor finally works with SPTM, TXM and XNU on at least M4 Pro now! It's not perfectly stable but good enough to trace most hardware. Let's see about M5 next, it might just work if I manage to disable cL4 / exclaves there […]

Nothing new, but I'm disappointed. Many years ago, Linux represented the alternative. The question was: "Why don't you just use Windows? It's easier." And the answer was, almost always: "To be free." The "bazaar" spirit of Linux and its distributions made us feel free. Personally, I've always […]

@vbabka just what kind of conference was that? 😳

@never_released a year ago that would've been an exciting project and I would be very curious how they archived it. Now I just don't even care :/

#kr2026 was fun! Had to leave a bit early to make it back to Germany but will definitely try to attend again next year, and then stay an additional night. Haven’t been to any other conference where just about every single talk was amazing

they also seem to try to do an online transaction that requires 3d secure authorization while also not supporting that in their terminal so i'm really not sure what their plan here is. even if i gave them one my real credit cards the transaction would fail for the same reason.

And finally: Initial USB4/Thunderbolt support for M1/M2/M3 on LKML: lore.kernel.org/asahi/20260830-b4-a… Note that this doesn't do PCIe or DispalyPort tunneling yet and is only useful if you want to connect two machines via USB4NET together for […]

You know how usb devices don't seem to work in #asahilinux after a suspend/resume cycle unless you replug them? thunderbolt does it better: After you suspend with an active connection you get to resume directly into a DART SError! But this made us realize what the actual problem is even for the […]

@valpackett also kinda funny that usb3-via-4 tunneling just works :D it's not the same sequence macos does because that would need an additional out of band notification but surprisingly this time the PHY seems to tolerate it. usually it answers to such abuse with a full SoC reset

Sven Peter @sven.social.treehouse.systems.ap.brid.gy · 22/08/2026

@valpackett it doesn't help that all my devices either negotiated usb/dp-altmode combined because they had SS ports downstream or just didn't have any downstream usb ports so I just never noticed

Sven Peter @sven.social.treehouse.systems.ap.brid.gy · 10/08/2026

@valpackett the native host interface itself works now, but only control ring 0 so even host to host still needs a bit more work. Devices are recognized but no tunnels can be brought up yet because the „other side“, I.e. PCIe, Display Controller and dwc3, is not done yet. Still makes for a nice […]

@valpackett I saw the original series and asked to be cced but then wasn’t so I was quite surprised they landed already. The rebase was rather annoying but luckily worked out. This is all related to the quite significant work on top of that since the Apple TBT/USB4 controller is quite unusual […]

@Sobex there's some pin/gpio that has to be configured with the pinctrl driver and when reworking all of this for the upstream atcphy i accidentally moved it to the wrong pin controller. I only looked at MMIO traces and compared macos vs. linux and that just didn't show up in the peripherals I […]

We also have this "minor" issue that we can't easily run our hypervisor on M4+ to trace and reverse engineer the hardware because Apple disabled their ARM ISA extensions in our boot mode. The major problem here is GXF/SPRR which changes the way […] [Original post on social.treehouse.systems]

during that time I finally took a stab at how we'll handle sleep states in #asahilinux. usually, this is done by PSCI running in a higher level (e.g. EL3) reached via hypercall but we're already running the kernel in the highest level possible. instead, someone proposed years ago to (ab-)use EFI […]

@valpackett that’s… odd. usb2 is surprisingly tolerant of the wires used and I’ve run it over much worse connections. maybe double check the solder joints 🤔

Stopping the system fans to heat up the system to shift clock phase by a few femtoseconds is one of the less hinged ideas I’ve seen come out of CERN lol. (AFAIU this was an experiment for a software retrofit to hardware otherwise incapable of such adjustments)

@fay59 yeah, I really haven’t been able to build something that’s not a greenfield project or proof of concept and you really have to take a very close look at the output because even the fancy models still get stuff wrong all the time.
