9:17:56 iska I want to flatten out the mezzano cdrom a little bit so I can boot it in uefi

9:50:04 iska it wants like 13k pages while I can only load 11 before running out of heap

9:59:50 iska anyone has a clue why efi has that memory limit to begin with, and can I remove it? cc fitzsim

10:04:45 fitzsim I didn't use EFI, I used coreboot/Libreboot

10:04:56 fitzsim can you install those? they'll probably be way less annoying

10:07:29 fitzsim or you could test in a VM with OVMF first, to get your bearings

10:47:20 iska fitzsim: I don't think there's any support for c612 chipset in coreboot

10:55:23 iska best I can do is manually modifying the bios and fiddling with settings

11:04:49 iska changed bios settings a little

11:05:27 iska Looking for paging disk with UUID 5C:F6:EE:79:2C:DF:5:A1:BA:4B:63:25:C4:1A:5F:10

11:05:27 iska (before "could not find boot device" panic)

11:12:29 iska FF's on apic still there

11:23:43 iska oh wow, disabling XAPIC2 fixed that

11:49:31 iska how is apic done in mezzano?

11:53:01 froggey hmm, interesting. there's no xapic2 support. I guess it should do some validation to make sure the apic version is right

11:55:12 froggey local apic stuff is all handled by supervisor>x86-64>cpu.lisp, it's used for the preemption timer & smp support

11:56:15 froggey does it get further with xapic2 disabled?

12:04:47 iska nope, still can't detect the drive

12:05:48 iska which input offset do I need to satisfy flatten-image?

12:06:13 iska (on the iso)

12:14:53 froggey I'm not sure that works, I always produced a raw image, flattened that, then generated the iso from the new flattened image

12:16:15 iska I want to re-flatten that image so it may fit in what efi kboot allows me to use

12:27:17 iska actually, my own cdrom I made a while back gives me a panic in efi too. Clears up a lot of things

12:29:57 iska gives almost same results, but it does a bunch of 8042 stuff instead of waiting

12:31:44 iska Okay, I'm gonna make a brand new image and make it a smaller cdrom

12:33:43 iska still doesn't clear up why it exactly needs iso in uefi to get further than a black screen

13:23:09 froggey basically the bootloader is very dumb when doing memory allocation during load, and if the image is large or fragmented that causes more allocations within the loader, which exhausts the internal heap

13:23:12 froggey another bug to fix

13:39:19 iska especially when function area becomes large
