05:48 <marcan> axboe: I see linux does have a panic_notifier_list mechanism, but it isn't really used for much aside from some core stuff

05:49 <marcan> do you think it'd make sense to hook that into nvme or the block layer as a whole, like macOS does?

05:49 <marcan> considering it's a panic situation, I'm guessing it would make sense to do it in individual drivers which have an emergency shutdown mechanism (like NVMe)

05:49 <marcan> instead of trying to make it wholly generic

12:02 <j`ey> jannau: if there was a GPU driver, it could still be used with simpledrm right?

12:02 <j`ey> there's no coupling between GPU and DCP there

12:05 <kettenis> you'd have to render into the live framebuffer; would be hard to avoid glitches that way

12:05 <kettenis> (but I'm not really and expert here)

12:06 <j`ey> more of a conceptual question than, obviously using DCP would be better in the end :D

12:08 <alyssa> j`ey: "yes but don't"

12:09 <j`ey> alyssa: fair

12:34 <_jannau_> the DCP driver should be good enough for testing the GPU driver. I should see that the m1n1 changes are merged to make testing easier.

12:35 <_jannau_> a little annoying since they depend on not formalized devicetree bindings

12:37 <_jannau_> kettenis: does openbsd ignore "reserved-memory" nodes with unknown compatibles?

12:38 <kettenis> OpenBSD ignores reserved-memory nodes of any type at this moment

12:39 <kettenis> Solely relies on the EFI memory map to describe reserved regions

12:39 <kettenis> So the real question is what u-boot does...

12:43 <kettenis> I think the relevant code lives in lib/efi_loader/efi_dt_fixup.c:efi_carve_out_dt_rsv()

12:44 <kettenis> doesn't look in any way at the compatible property of the node

12:44 <kettenis> so I think you're in trouble there

13:13 <axboe> marcan: yeah we can wire that up, I can take a look

17:03 <sven> https://f.svpe.de/c677aa8b4d557e7b99fd8c59903cf840bac3d68969ac415bb2ff53e40c77000a_xnu-bootargs.txt list of everything that probably is a usb bootarg generated by setting a breakpoint to PE_parse_boot_argn and just dumping the first string argument

17:03 <sven> the ones with -debug are usually fun and take a "level" as an argument. generally whatever-debug=0xffff is good enough to enable everything

17:03 <sven> erm. *XNU bootarg
