06:32 <Ry_Darcy> Here is a little (big) puzzle for some or all of you. Running Debian 6.3.x on an M1 Mini. I can compile the abovementioned kernel using rust (installed version 1.66) with no problems, do the dpkg magic and the machine reboots with no problems. I prefer a .config very much trimmed-down to avoid running with top-heavy and unnecessary drivers/debug options etc. All very well, if however, I try to compile a 6.4-rcx kernel using the .config file mentioned

06:33 <Ry_Darcy> the option to enable rust using "make LLVM=${CLANG_VERSION} menuconfig" is not appearing at all. make LLVM=${CLANG_VERSION} rustavailable - returning "Rust is available" is displayed, which is initially reassuring. To regress somewhat, in scripts/min-tool-version.sh, echo 1.62.0 is hard-coded. With my current version of Rust (1.69), I have adjusted scripts/min-tool-version.sh accordingly, but still no options for rust in make menuconfig... Anyone an

06:35 <Ry_Darcy> Anyone any bright ideas/pointers..?

07:02 <mps> Ry_Darcy: I can confirm your observation. last night superficially looked at 6.4-rc2 and found same as you

07:05 <Ry_Darcy> Strange.. I wonder what is missing/incorrect..

07:06 <mps> I don't have much free time last days to look what is needed for 6.4

07:14 <Ry_Darcy> Further information, I even downgraded rust to 1.62 (rustup override set 1.62) to see if it would make any difference, same result - no rust options in menuconfig.

07:21 <mps> HAVE_RUST=n

07:23 <mps> result of `make LLVM=1 rustavailable` is https://tpaste.us/xyjw

07:28 <Ry_Darcy> The bindgen error can be corrected with "cargo install --locked --version 0.56.0 bindgen" methinks.

07:28 <mps> arch/Kconfig have config HAVE_RUST

07:28 <Ry_Darcy> The first error 1.62<-> 1.66 is another matter...

07:29 <mps> could be missconfig in 6.4-rc2 upstream

07:42 <Ry_Darcy> No idea. Perhaps.

08:01 <Ry_Darcy> Frustrating, because all of this rust stuff is not working/failing silently so I do not know where to look.

08:08 <jannau> try until `make rustavailable` doesn't fail

08:08 <jannau> is there anything interesting in v6.4-rc which requires rust?

08:10 <mps> I don't see anything

08:12 <jannau> upstream hasn't yet bumped to rustc/bindgen versions, so you need 1.62 / 0.56. asahi kernel has patches to bump the required versions

08:13 <mps> I'm playing with 6.4 for riscv SBC, not for m1

08:20 <Ry_Darcy> As mentioned already, downgrading to rust 1.62 will still not work.

08:21 <Ry_Darcy> The 6.4-rc2 kernel I downloaded from Asahi (tags).

08:35 <mps> Ry_Darcy: does it have asahi patches or it is clean copy of mainline

08:37 <jannau> mps: I'm not sure if rust support is there for all architectures. I'm not even sure if the arm64 rust support was already merged

08:38 <mps> also I'm not sure, I build with rust only asahi-wip kernels

08:40 <mps> (imo, rust is not yet good idea to use for kernel)

08:41 <jannau> Ry_Darcy: no arm64 rust support in v6.4-rc2, v6.4-rc2 is the upstream tag from Linus without asahi GPU driver

09:00 <Ry_Darcy> That would explain things. Thank you. As stated already, kernel 6.3 (with GPU etc.) compiles flawlessly with rust.

10:44 <Ry_Darcy> @Jannau any new on the M2 Mini installer, even a test installer, despite DCP issues? This has been lying on my desk now for five months - unused :(

10:45 <Ry_Darcy> new = news

10:48 <ChaosPrincess> if you dont need a display and ok with operating it over serial, its not hard to hack together an installer that supports it yourself

10:48 <ChaosPrincess> probably won

10:48 <ChaosPrincess> 't even need to make changes, just run the installer from git

10:49 <jannau> x = x ** y

10:50 <jannau> if you get apple devices early you could send them to marcan which might speed things up

10:50 <Ry_Darcy> @ChaosPrincess Thanks for the information. I would need a display in my case.

10:50 <ChaosPrincess> in that case, well, wait until we get dcp support

10:50 <ChaosPrincess> or, y'know, start hacking on it yourself

10:50 <Ry_Darcy> Quite..

10:52 <ChaosPrincess> well, yea, it has macos, so...

10:52 <ChaosPrincess> and its not a console/iphone where you want to stay at a lower official firmware if you want to run your own stuff

10:52 <Ry_Darcy> Not quite on release day. macos, no thanks. Let it sit further then.

10:52 <ChaosPrincess> so why buy early and leave on shelf

10:53 <marcan> release was 4 months ago, for a start

10:53 <marcan> not even, a bit less

10:54 <Ry_Darcy> Masochism, eagerness, perhaps.

10:54 <marcan> if you purchase an unsupported device that's on *you*, and every time you annoy the developers you are making us even less likely to prioritize supporting your device

10:55 <Ry_Darcy> Ordered in Jan. Came at the start of Feb. One of those exotic 24GB models.

10:56 <Ry_Darcy> Don't be so bloody snotty. I asked this question about two months ago. That is hardly annoying anyone.

10:58 <psykose> and 4 months too :-)

10:58 <mps> psykose: you have apple silicon machine?

10:58 <psykose> nope

10:58 <mps> ah ok. I had a hope

11:02 <chadmed> macos isnt *that* useless, you can definitely use the machine

11:02 <chadmed> honestly the very worst thing about it for me in daily use is how shit the default terminal app keybinds are

11:02 <chadmed> im so used to konsole i just instinctively go to use konsole shortcuts and end up on a new virtual desktop or something

11:03 <psykose> it's also not that outlandish to just put a whole vm fullscreen and forget it half the time, i've seen people do that

11:03 <psykose> not free of course in performance :p

11:03 <mps> also, when I got first m1 I used qemu on macos to have linux (alpine ofc). I have no idea how to use macos for my work

11:04 <psykose> i think you type brew install a bunch of times and you get a compiler

11:04 <psykose> easy

11:04 <mps> rihgt

11:05 <mps> even used qemu when it had to be patched for HVF to work. Happily my son communicated with upstream to get these patches working

11:06 <chadmed> i have a terrible thinkpad for work so my machines are just for having fun + playing

11:06 <mps> even now I think that the qemu on macos could be very useful

11:07 <mps> with linux in qemu, meant to say

19:10 <TellowKrinkle> Ry_Darcy: Okay, now imagine that 60 other people do the same thing. Now you've gone from one every two months to one a day. See how that might get annoying?
