ACPI is documented, that's completely independent from the Hurd. That being said, start from the start: the shutdown trigger is performed by the shutdown translator, in shutdown/shutdown.c, which calls into the acpi translator. Then it's a matter of following the function calls, put mach_print() calls along the way, and check what is actually happening. Samuel
Re: poweroff support on Hurd?
I'm running baremetal on a T61 (32bit) laptop. The poweroff (shutdown -h now) also doesn't work, hurd terminates but system remains on. Here's a situation on my system: wojciech@saiph:~$ showtrans /servers/shutdown /hurd/shutdown wojciech@saiph:~$ showtrans /servers/acpi /hurd/acpi wojciech@saiph:~$ showtrans ls /servers/acpi/tables APIC BOOT FACP MCFG SSDT SSDT SSDT TCPA 'ASF!' ECDT HPET SLIC SSDT SSDT SSDT dunno what I'm looking at unfortunately, docs needed. cheers Voitek [PS. picking up on what Samuel wrote in this thread, I'm willing to look at the source when time permits, as well as many aspects of Hurd; this is why I bought that laptop:). ACPI would be cool to see the remaining battery percentage... For now I got stuck in the trivial stuff such as Xorg won't start etc., have to resolve that first.] --- /^..^\ ( (••) ) (|)_._(|)~ Wojciech (Voitek) ANISZEWSKI OrcId : https://orcid.org/-0002-4248-1194 Scholar: https://tinyurl.com/y28b8gfp RG : https://www.researchgate.net/profile/Wojciech_Aniszewski Twitter: @echo_dancers3 GPG ID : AC66485E Le 2023-12-07 13:03, Svante Signell a écrit : On Thu, 2023-12-07 at 08:16 +0200, Martin-Éric Racine wrote: [2023-12-07 08:14](HURD i386)perkelix@pxeth:~$ showtrans /servers/shutdown /hurd/shutdown [2023-12-07 08:14](HURD i386)perkelix@pxeth:~$ showtrans /servers/acpi /hurd/acpi [2023-12-07 08:14](HURD i386)perkelix@pxeth:~$ ls /servers/acpi/tables/ APIC FACP SSDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT [2023-12-07 08:14](HURD i386)perkelix@pxeth:~$ On one of my images: ls /servers/acpi/tables/ APIC FACP HPET WAET

?? There are plenty of wiki pages, and the whole source code is just
there to be looked at. The shutdown translator is 160 lines long and
will tell you which RPC it's trying to do to shut down the machine. From
there you have everything.
Read the source, Luke.
This was said to people 20-30 years ago when the free software movement
deployed, this is just exactly the same now, for exactly the same
reasons.

mach_print("foobar\n"); is a very powerful tool, for a start, to know
what is actually happening.

Possibly. The thing is, given how Hurd remains a sketchily documented OS, I wouldn't remotely know where to look or using what tools. Martin-Éric
