Because fat type is tied to cluster count

Is it a mistake though

Who unironically uses fat12 with technology from 2024

#

neon crane Who unironically uses fat12 with technology from 2024

per spec, the type of FAT is determined by the size of the volume

#

and supporting FAT12 and FAT16 is a few dozen more lines of code

#

especially in a high level language like C

spare sky Jul 2, 2024, 1:12 PM

analog berry Because fat type is tied to cluster count

^ whoops, infy already mentioned it

warped plinth Jul 2, 2024, 1:15 PM

Its used automatically for small filesystems

#

You cant force a bigger fat type because of what luk said

neon crane Jul 2, 2024, 1:18 PM

#

analog berry Its used automatically for small filesystems

who would want a <2mb file system

spare sky Jul 2, 2024, 1:19 PM

#

neon crane who would want a <2mb file system

would you want to refuse mounting a very small file system because it has too few clusters?

#

just for the sake of saving 8 lines of code

neon crane Jul 2, 2024, 1:20 PM

#

i mean fair enough

#

but it's not just “8 lines of code”

#

you gotta write different next-cluster-number accessing logic

spare sky Jul 2, 2024, 1:21 PM

#

which is like a handful of lines

#

well, except when it goes over sector boundaries

#

but that is also not more than a dozen lines

neon crane Jul 2, 2024, 1:22 PM

#

like

if (IsFat32()) {
    ReadSector(buff, sector + currCluster / 128);
    return uint32Ptr(buff) + currCluster % 128;
} else if (IsFat16()) {
    ReadSector(buff, sector + currCluster / 256);
    return uint16Ptr(buff) + currCluster % 256;
} else { // Fat12
    // huh
}

neon crane Jul 2, 2024, 1:22 PM

#

spare sky well, except when it goes over sector boundaries

lol

#

thats fucked up

#

but yeah just a couple more lines

#

oh its not that hard

#

the other diff is how to identify the root directory

spare sky Jul 2, 2024, 1:23 PM

#

nah

neon crane Jul 2, 2024, 1:23 PM

#

on fat32 it's linked to a cluster specified in the BPB

spare sky Jul 2, 2024, 1:23 PM

#

it's the same as FAT16

neon crane Jul 2, 2024, 1:23 PM

#

and is a regular cluster chain

#

on fat16 and fat12 its fixed I believe

spare sky Jul 2, 2024, 1:23 PM

#

so if you already do FAT16, you already have FAT12 root directory support

spare sky Jul 2, 2024, 1:29 PM

#

neon crane like ```c if (IsFat32()) { ReadSector(buff, sector + currCluster / 128); ...

oh well, I guess if you want to write a function that returns a pointer to a FAT entry in a buffer, then it's not easy for FAT12
I have readFATEntry and setFATEntry functions, basically

neon crane Jul 2, 2024, 1:34 PM

#

spare sky oh well, I guess if you want to write a function that returns a pointer to a FAT...

It's really not

analog berry Jul 2, 2024, 2:59 PM

#

spare sky which is like a handful of lines

Tbh root dir being at a fixed place and fixed size is annoying

spare sky Jul 2, 2024, 3:00 PM

#

well, I'm assuming already having implemented FAT16

#

well my ext2 driver is a bit borked and I've managed to half consistently reproduce it by untarring and editing a file in that tarball

#

its nothing too apparent at first glance but it ends up having e2fsck scream at me

#

and later down the line will cause an assert fail

#

hm it could be some vnode refcounting memes

robust bobcat Jul 7, 2024, 12:18 AM

#

ext2 is always fun

grand shadow Jul 7, 2024, 1:02 AM

#

yup, it is a refcount meme

#

link count = 0 with one last reference to it somewhere

#

which explains the behaviour its getting, which is leaving more things allocated than expected by e2fsck

#

hm it doesn't seem like a bug with ext2 in specific, also reproducible on tmpfs

#

well at least I actually know the issue now

grand shadow Jul 7, 2024, 3:24 PM

I Am Not Releasing The File

finally

./configure also caused this and iirc git clone too

so gonna check that as well

one less bug though

gonna see if git clone still does it

I wanted to see if astral could run a rainbow triangle opengl program

analog berry Jul 9, 2024, 4:27 PM

The real question is does it boot on real hw

grand shadow Jul 9, 2024, 4:27 PM

#

Last time I checked it got to a bash prompt but the kb didnt work

#

That was like last year tho lol

obsidian pivot Jul 9, 2024, 4:28 PM

that doesn't matter, it must only be able to run rainbow triangle

grand shadow Jul 9, 2024, 4:28 PM

#

obsidian pivot I wanted to see if astral could run a rainbow triangle opengl program

Probably can, quake is perfectly playable so if mesa is ported I dont see why not

obsidian pivot Jul 9, 2024, 4:28 PM

#

it has opengl?

#

3.3?

analog berry Jul 9, 2024, 4:28 PM

obsidian pivot Jul 9, 2024, 4:28 PM

(for my triangle program specifically)

analog berry Jul 9, 2024, 4:28 PM

obsidian pivot it has opengl?

Mesa has opengl 4.5

#

Fully in software

obsidian pivot Jul 9, 2024, 4:29 PM

but does he have opengl?

analog berry Jul 9, 2024, 4:29 PM

Yes

obsidian pivot Jul 9, 2024, 4:29 PM

hold up lemme cross compile my triangle

grand shadow Jul 9, 2024, 4:29 PM

Tyrquake does software rendering on its own thing Im pretty sure

I dont have opengl

#

I will accept a mesa and llvmpipe pr tho meme

#

Or I can do that when I get home

analog berry Jul 9, 2024, 4:31 PM

Wait u don't have mesa ported?

grand shadow Jul 9, 2024, 4:31 PM

Ohh

#

Well shouldnt be too hard

grand shadow Jul 9, 2024, 4:32 PM

#

The biggest thing is the llvm part of it but meh I can do that as a break from trying to catch that extra vnode refcount

#

Smth is causing the conftest vnodes to have an extra reference when running ./configure

#

Which kinda breaks ext2 a bit

#

If the system is turned off

analog berry Jul 9, 2024, 4:48 PM

u can shutdown the system?

you can use soft pipe

it'll handle quake 3 right enough

warped plinth Jul 9, 2024, 8:56 PM

so theoretically, if i just mount the iso provided on github, copy out the kernel & initrd to my boot partition, then make a limine entry, it could work?

warped plinth Jul 9, 2024, 9:16 PM

#

so it loads the kernel, but, it seems stuck on smp? it just prints smp: 12 processors then seems to freeze. is there a kernel option to disable smp?

grand shadow Jul 9, 2024, 9:26 PM

#

weird

#

Pass nosmp to the cmdline

#

Think thats the option

#

My ipi might not work on real hw or smth

#

And Ive probably fixed some bugs from the version in the release page its like over a month old I think

#

Doesnt even have a page cache lol

warped plinth Jul 9, 2024, 9:29 PM

#

oh yea lol, i should specifically mention i'm using the release, not built from source

grand shadow Jul 9, 2024, 9:30 PM

Otherwise thats another thing Ill have to debug if its not fized in source

You could get it to boot but your keyboard and touchpad wouldn't work

grand shadow Jul 9, 2024, 9:40 PM

grand shadow Jul 9, 2024, 9:41 PM

like I did with old astral

grand shadow Jul 10, 2024, 12:49 AM

I'm starting to think that it might be something to do with the fact that first first pages of the 4gb+ section are in the initrd

and my multiple page allocation (used by the flanterm initialisation) doesn't like that too much

warped plinth Jul 10, 2024, 11:53 PM

ahh

grand shadow Jul 10, 2024, 11:54 PM

and start passing commands to it to draw stuff

it's the last 2 that are the hard part

craggy tide Jul 11, 2024, 2:40 AM

i do not think hardware to test with is the issue

grand shadow Jul 11, 2024, 2:43 AM

#

its decently stable on real hw without smp

#

with smp it boots to fvwm but then gets funky and locks up

#

and runs better than on kvm I think

#

either way it runs on the two computers I have to thats a win

#

even tho my laptop is better supported cuz ps2 mouse

craggy tide Jul 11, 2024, 2:49 AM

#

just get a motherboard with ps2 ports

#

like seriously, godsent

either that or wait for me and @robust geyser to finish our portable USB driver :^)

grand shadow grrr I need to fix these last few bugs but the motivation is severely lacking

What helps me with that is to take a day to just chill out, then promise to come back stronger tomorrow and tackle at least one large problem, then actually follow through with it

Idk if it'll help you, but it does with me

neon crane Jul 14, 2024, 5:24 PM

#

@grand shadow what references did you use for your NVMe driver?

analog berry Jul 14, 2024, 5:25 PM

#

the nvme spec is very good

grand shadow Jul 14, 2024, 5:26 PM

#

yeah, mostly the spec

neon crane Jul 14, 2024, 5:27 PM

#

i saw a lot of macros reading astral's impl, why is that?

#

also which parts of the spec were used? the base spec?

grand shadow Jul 14, 2024, 5:30 PM

#

yeah the base spec

grand shadow Jul 14, 2024, 5:30 PM

#

neon crane i saw a lot of macros reading astral's impl, why is that?

I mean is there any issues with that?

neon crane Jul 14, 2024, 5:32 PM

#

No

#

I was just curious about the reasoning

grand shadow Jul 14, 2024, 5:32 PM

idk I just felt like it was more readable than having a bunch of shifts and masks everywhere

neon crane Jul 19, 2024, 5:01 PM

@grand shadow found an issue I think

#

https://github.com/Mathewnd/Astral/blob/rewrite/kernel-src/include/x86-64/arch/pci.h#L70

#

#

the edgetrigger and deassert are supposed to be flipped

#

so you or the value with 1<<15 if edgetrigger is FALSE and not true

#

same with deassert

#

the OSdev wiki article on PCI doesnt have this issue

uh, that doesn't sound right

#

your assessment that is, doesn't sound right

#

in that what you see at the top there is not Limine output

#

at any point

fleet osprey Jul 21, 2024, 2:04 AM

#

Yeah, of course
Thats astral

#

Was my wording confusing? Sorry

craggy tide Jul 21, 2024, 2:04 AM

#

yes

fleet osprey Jul 21, 2024, 2:05 AM

#

Limine looked like that
Had that random garbage at the bottom, and the bottom half of the limine boot menu at the top

#

The same state persisted into astral, where it hung (that pic)

craggy tide Jul 21, 2024, 2:05 AM

#

can you show a picture of that

craggy tide Jul 21, 2024, 2:05 AM

#

fleet osprey HP ProBook 4540s Uhhh... Yeah

likewise with this, is this before or after booting astral?

fleet osprey Jul 21, 2024, 2:05 AM

#

Mhmm, and that was before

#

After booting on the probook it showed a garbled version of an astral error message

#

Undecipherable

craggy tide Jul 21, 2024, 2:07 AM

#

it looks like a wrong pitch

#

are both of these systems BIOS?

fleet osprey Jul 21, 2024, 2:08 AM

#

Both are UEFI, but I would need to double check what mode they're booting in, as theyve both had CSM on or off in various times

craggy tide Jul 21, 2024, 2:09 AM

#

well for the first one, Limine tells you

#

you said you can see the top of the screen

fleet osprey Jul 21, 2024, 2:09 AM

#

Heres limine in the glitched state, in CSM mode, on the Latitude

rn_image_picker_lib_temp_55efd5c6-429b-4b73-95fe-197744c05388.jpg

craggy tide Jul 21, 2024, 2:09 AM

#

ah okay so it is the bottom

#

try UEFI

fleet osprey Jul 21, 2024, 2:10 AM

#

Let me try again with UEFI boot and see if it's the same, one sec

#

Yeah, same idea at the same time lol

craggy tide Jul 21, 2024, 2:10 AM

#

yeah

#

lol

fleet osprey Jul 21, 2024, 2:10 AM

#

Nah looks fine on UEFI

#

Weird

#

Astral hangs at the same spot, ending with PCI logs, though

craggy tide Jul 21, 2024, 2:11 AM

#

well i was expecting UEFI to look fine tbh

#

what about the other machine?

fleet osprey Jul 21, 2024, 2:12 AM

#

The ProBook does those glitches on UEFI

#

Just checked

craggy tide Jul 21, 2024, 2:13 AM

#

likewise, what about BIOS?

fleet osprey Jul 21, 2024, 2:13 AM

#

Working on it

craggy tide Jul 21, 2024, 2:13 AM

#

kk

fleet osprey Jul 21, 2024, 2:14 AM

#

Weird
Works fine on BIOS

craggy tide Jul 21, 2024, 2:14 AM

#

i wouldn't say it's weird

#

both of these issues seem related to the way the framebuffer information has been passed to the bootloader

#

switching BIOS and UEFI changes that radically

fleet osprey Jul 21, 2024, 2:16 AM

#

In each case I can vouch that GRUB works on this machine
I used both of these machines with Linux at various times, with both BIOS and UEFI mode

craggy tide Jul 21, 2024, 2:16 AM

#

both of them or just the latter?

#

and especially, at which resolution

fleet osprey Jul 21, 2024, 2:19 AM

#

The ProBook, Latitude (the 2 we were just talking about), and T480 support both, and have been used with both, at native laptop panel resolution (varies between machine)
The T14 has only been used in UEFI
The OptiPlex 755 and Precision T1650 have both only been used in BIOS

craggy tide Jul 21, 2024, 2:19 AM

#

to be clear

#

i meant what resolution was GRUB using

#

because Linux has its own video drivers

#

so the issue wouldn't apply

fleet osprey Jul 21, 2024, 2:20 AM

#

Yes, that's what I was referring to as well, GRUB runs at full resolution

#

I could go double check if necessary on each if you want, I have a bootable GRUB USB

craggy tide Jul 21, 2024, 2:21 AM

#

that would be nice, if it's not too much effort

#

alongside having GRUB print the video mode info

fleet osprey Jul 21, 2024, 2:21 AM

#

No prob
That's kind of what I'm here doing lol, testing things since I have some spare time

craggy tide Jul 21, 2024, 2:22 AM

#

ty lol

#

it is actually quite unfortunate and weird to see 2 of your machines both fail with Limine, and in similar video mode related ways

#

i can't say i've ever seen anyone report anything similar before

#

especially the shifted up framebuffer one

fleet osprey Jul 21, 2024, 2:24 AM

#

Also, Astral has the same bug as on the T480, here in the ProBook in BIOS
Might want to double check this image in QEMU quick, since its weird that this image would have the same weird issue on 2 machines

rn_image_picker_lib_temp_e2a593c3-4417-4c7b-a9ec-a38ce4ec7f63.jpg

craggy tide Jul 21, 2024, 2:25 AM

#

there could be actually a chance of your drive being faulty or the image being corrupted :^)

fleet osprey Jul 21, 2024, 2:26 AM

#

Possible, that's why I'm checking in QEMU directly with the image Mathew linked

#

While I wait for it to boot I'll check those laptops with GRUB

craggy tide Jul 21, 2024, 2:28 AM

#

i'd say that i think the broken drive hypothesis is more likely than the image being faulty; that said having you try a known-working image on a different usb stick would be the proof that neither are the case

fleet osprey Jul 21, 2024, 2:33 AM

#

- ProBook - BIOS: GRUB defaults to 1024x768 (and displays correctly like that), but if told to use 1366x768 (native panel res), works fine
- ProBook - UEFI: Same as above

- Latitude - BIOS: GRUB defaults to 1024x768 (and displays correctly), but if told to use 1920x1080 (native panel res), works fine
- Latitude - UEFI: same as above

#

also astral booted fine in QEMU so ig it's just either a Ventoy issue (would be weird, since limine seems to successfully load the initrd, typically when I see ventoy issues, whatever I'm booting just fails to find the drive at all) or a bad USB stick issue

#

let me try another stick, flashed directly, on the 2 machines that made it far enough to care

craggy tide Jul 21, 2024, 2:40 AM

#

whenever you can, try this on a fresh usb stick, as well

📎 template.iso

fleet osprey Jul 21, 2024, 2:41 AM

#

lmfao, the probook wants nothing to do with booting the USB directly, at least in BIOS mode
in UEFI it's the same garbled mess, but in BIOS it just kicks me to PXE boot

#

welp

craggy tide Jul 21, 2024, 2:44 AM

#

some machines may not like this kind of hybrid ISO on a USB stick in BIOS mode

#

that's not that interesting of a find

#

setting the protective MBR GPT partition as bootable may get them to boot, but then they won't boot in UEFI mode on other machines so whack-a-mole

#

so in UEFI you still get the wrong pitch-looking one?

fleet osprey Jul 21, 2024, 2:46 AM

#

yup

craggy tide Jul 21, 2024, 2:46 AM

#

alright

#

i really hope this isn't a situation where GRUB just has a list of quirks for these specific machines

fleet osprey Jul 21, 2024, 2:47 AM

#

And on the T480 with UEFI, Limine works great, then Astral gets to here and it just hangs here it seems

craggy tide Jul 21, 2024, 2:47 AM

#

fleet osprey lmfao, the probook wants nothing to do with booting the USB directly, at least i...

just to be clear, this is with the ISO i sent or the astral one?

fleet osprey Jul 21, 2024, 2:47 AM

#

keyboard LEDs don't seem to respond

fleet osprey Jul 21, 2024, 2:48 AM

#

craggy tide just to be clear, this is with the ISO i sent or the astral one?

that's astral, I'm about to test your ISO rn, just didn't want to reflash twice

craggy tide Jul 21, 2024, 2:48 AM

#

alright, hopefully the ISO i sent boots in both modes

fleet osprey Jul 21, 2024, 2:51 AM

#

template works great with T480 UEFI, doesn't boot on T480 BIOS

#

testing on ProBook now

#

works great on ProBook BIOS, boots but garbled on ProBook UEFI

#

works great on Latitude UEFI & BIOS

craggy tide Jul 21, 2024, 2:54 AM

#

was the T480 even having an issue to begin with?

#

wait, the latitude being the one with the shifted-up framebuffer issue?

fleet osprey Jul 21, 2024, 2:55 AM

#

nope but I just already had it hooked up so I figured I would check

fleet osprey Jul 21, 2024, 2:59 AM

#

craggy tide wait, the latitude being the one with the shifted-up framebuffer issue?

yup, Latitude had the bugged graphics in BIOS with Ventoy -> Astral ISO, but not UEFI
unfortunately the Astral ISO doesn't boot flashed directly with BIOS, I could try setting the partition as bootable like you said and see if I could get it to boot to try to reproduce it though

craggy tide Jul 21, 2024, 3:01 AM

#

but the iso i sent does work booted directly in BIOS mode?

#

because you said it works great BIOS and UEFI

fleet osprey Jul 21, 2024, 3:01 AM

#

yeah

#

astral doesn't though

#

¯_(ツ)_/¯

craggy tide Jul 21, 2024, 3:03 AM

#

the wrong pitch could have to do with some shenenigans pulled off by Ventoy

#

would be interesting to load this iso with Ventoy to see if it can reproduce

fleet osprey Jul 21, 2024, 3:05 AM

#

but only the ProBook in UEFI mode had the wrong pitch bug if I'm not mistaken
it's the only one that's 100% garbled

#

well actually yeah I could try that, idk what i was thinking of there 🤦

#

yeah, ProBook UEFI -> Ventoy -> template still has the busted pitch

craggy tide Jul 21, 2024, 3:08 AM

#

ah sorry nvm

#

this is the shifted up fb

#

not the wrong pitch

#

the wrong pitch one is the completely garbled one

fleet osprey Jul 21, 2024, 3:08 AM

#

yup

craggy tide Jul 21, 2024, 3:08 AM

#

so this is shifted up then?

#

with Ventoy?

fleet osprey Jul 21, 2024, 3:09 AM

#

ProBook UEFI -> Ventoy -> template has the bad pitch, as did everything else I tried with it booting Limine in UEFI

craggy tide Jul 21, 2024, 3:10 AM

#

what about the Latitude one though?

fleet osprey Jul 21, 2024, 3:10 AM

#

Latitude BIOS (the one with the shifted up screen) -> Ventoy -> template is fine

#

the same setup booting astral is not

craggy tide Jul 21, 2024, 3:11 AM

#

that's odd

#

i wonder if the Astral Limine config file forces a resolution or something

fleet osprey Jul 21, 2024, 3:13 AM

#

doesn't seem like it

#

#

let me try to reproduce this config

fleet osprey Jul 21, 2024, 3:15 AM

#

the file hashes don't match up, so presumably they're different versions of limine

craggy tide Jul 21, 2024, 3:15 AM

#

they are but it shouldn't matter

#

can you send liminebg.bmp

fleet osprey Jul 21, 2024, 3:16 AM

#

it's gonna take a hot minute to upload on my DSL, give it ~1m, it's like 24MB

craggy tide Jul 21, 2024, 3:16 AM

#

no worries

fleet osprey Jul 21, 2024, 3:16 AM

#

ah, that was faster than I thought

craggy tide Jul 21, 2024, 3:19 AM

#

ok try this

📎 template.iso

fleet osprey Jul 21, 2024, 3:21 AM

#

k, one sec

#

bugged when loaded via ventoy

#

let me try directly

#

not bugged when loaded directly

craggy tide Jul 21, 2024, 3:24 AM

#

ok so the template that i sent earlier, when loaded via ventoy, is fine, but this template isn't?

fleet osprey Jul 21, 2024, 3:24 AM

#

I believe so

#

let me double check

#

indeed

#

Latitude BIOS -> Ventoy -> old template.iso is fine
Latitude BIOS -> Ventoy -> new template.iso has the same pushed up on the screen issue

craggy tide Jul 21, 2024, 3:27 AM

#

ok then it sounds like some sort of memory corruption of some kind

#

try this one

📎 template.iso

fleet osprey Jul 21, 2024, 3:30 AM

#

works fine via ventoy

craggy tide Jul 21, 2024, 3:32 AM

#

yeah i think i may have some idea of what's going on here

fleet osprey Jul 21, 2024, 3:32 AM

#

hm?

craggy tide Jul 21, 2024, 3:33 AM

#

it's probably a memory corruption related to when Limine draws the shading around the terminal box

#

with this specific shading width

#

which happens to be the same as the margin width

#

now the issue is: how to reproduce without needing Ventoy's "layout randomisation" lol

fleet osprey Jul 21, 2024, 3:37 AM

#

also it's interesting that it only happens on that one laptop
I can't reproduce that issue on anything else

craggy tide Jul 21, 2024, 4:03 AM

#

@fleet osprey could you try this one?

📎 template.iso

craggy tide Jul 21, 2024, 4:03 AM

#

fleet osprey also it's interesting that it only happens on that one laptop I can't reproduce ...

it's likely some very specific corruption, idk

fleet osprey Jul 21, 2024, 4:03 AM

#

sure, one sec

#

same issue, but now there's a cyan box around the bottom, left, and right of "real" screen

craggy tide Jul 21, 2024, 4:06 AM

#

same issue in the sense that it's shifted?

#

(the cyan box is intentional)

fleet osprey Jul 21, 2024, 4:07 AM

#

craggy tide same issue in the sense that it's shifted?

yeah

craggy tide Jul 21, 2024, 4:07 AM

fleet osprey Jul 21, 2024, 4:32 AM

#

Oh really? Ok then, I would've thought if the fb pointer corrupted it would just be dumping image data somewhere in RAM, or elsewhere (and probably crash)

craggy tide Jul 21, 2024, 4:33 AM

#

i mean it would, and it likely did, it's whatever was before the actual framebuffer window

#

it's just that the pointer got corrupted a bit, only a low byte or something, that caused it to slide back a bit

#

but still have parts of it visible

fleet osprey Jul 21, 2024, 4:34 AM

#

Ahh, I see

#

Ok then
Well I'll try that new build on the ProBook when I'm back then

craggy tide Jul 21, 2024, 4:34 AM

#

sure

#

i have a uhhhh

#

my guess would be 80% chance that it is fixed

#

the issue is just too similar and too coincidental, and caused by Astral's Limine config settings (well, not caused, but it shows because of that)

#

@fleet osprey this fails both when loaded with Ventoy and not, right?

fleet osprey Jul 21, 2024, 6:19 AM

iirc it does, yes
I can check again, hang on

what's the resolution of this laptop? can you try editing the config to change the resolution to something else?

1366x768

craggy tide Jul 21, 2024, 6:22 AM

i'll send you an img

you should be able to mount that and edit the config

craggy tide Jul 21, 2024, 6:24 AM

it's ini INTERFACE_RESOLUTION=1234x1234

btw

fleet osprey Jul 21, 2024, 6:26 AM

k

#

working on it

#

forcing 1024x768 (what GRUB defaults to) works

#

but forcing 1366x768 break, unlike on GRUB

#

interesting

craggy tide Jul 21, 2024, 6:34 AM

#

could you print the mode info with grub

#

for 1366x768, or generally the mode listing it prints

#

google how to do it because i do not remember

fleet osprey Jul 21, 2024, 6:34 AM

#

sure

#

oh yeah it's not vbeinfo on UEFI

#

it's videoinfo

#

craggy tide Jul 21, 2024, 6:39 AM

#

but that's UEFI

#

the issue happens on BIOS right?

fleet osprey Jul 21, 2024, 6:40 AM

#

nope

#

this issue only happens on UEFI

#

not BIOS

craggy tide Jul 21, 2024, 6:40 AM

#

oooooooohhhhhhhhhhhhh

#

holy shit

#

i thought it was BIOS lmao

#

sorry

fleet osprey Jul 21, 2024, 6:40 AM

#

have you been hacking the wrong code this entire time?
lmao, sorry

craggy tide Jul 21, 2024, 6:40 AM

#

yes

#

i did sort out some issues there though

#

i needed to do it anyways so i guess there's that

#

that explains why there were no changes with different tests lol

fleet osprey Jul 21, 2024, 6:41 AM

#

yeah

craggy tide Jul 21, 2024, 6:42 AM

#

so the pitch according to grub appears to be exactly 1366*4

#

let's see what Limine thinks the pitch is, i guess

#

there may be an issue with calculating the colour depth in Limine

#

i see no other place where it could fail

fleet osprey Jul 21, 2024, 6:45 AM

#

could try forcing it to always think 4 no matter what anything else says to see if that's it I suppose

craggy tide Jul 21, 2024, 6:46 AM

#

i mean i feel like that'd work

#

but sure let's try

fleet osprey Jul 21, 2024, 6:47 AM

#

well yeah but then if that ends up not being the issue at all, you don't need to go debug that code
idk, that's typically how I try to solve issues

craggy tide Jul 21, 2024, 6:48 AM

#

📎 template.hdd

craggy tide Jul 21, 2024, 6:48 AM

#

fleet osprey well yeah but then if that ends up not being the issue at all, you don't need to...

oh no, i mean, i understand that and i completely agree, but when i am confident something isn't needed, especially when sending images to other people is necessary, i try to avoid it

fleet osprey Jul 21, 2024, 6:50 AM

#

hmmm

#

that didn't fix it

craggy tide Jul 21, 2024, 6:50 AM

#

oh damn

fleet osprey Jul 21, 2024, 6:51 AM

#

I flashed that image, set the res to 1366x768 in the new config file, booted, and it's still the same

craggy tide Jul 21, 2024, 6:55 AM

#

try this, i force the pitch to 5464 manually

📎 template.hdd

fleet osprey Jul 21, 2024, 6:59 AM

#

still busted... somehow

craggy tide Jul 21, 2024, 7:03 AM

#

odd

#

looks exactly the same?

#

maybe the pitch is reported the same as what GRUB says

#

and the issue is that it's not true

#

which would tie in with this UEFI being fucked and GRUB probably having some quirk

fleet osprey Jul 21, 2024, 7:05 AM

#

craggy tide looks exactly the same?

yeah, same thing

#

and it really wouldn't shock me to learn that HP of all manufactureres wrote terrible firmware for a crappy consumer grade laptop

#

it's just odd that neither GRUB, nor Windows, or anything else that I've found has this same issue

craggy tide Jul 21, 2024, 7:10 AM

#

well but on my end i can say that it is likewise odd that no other machine exhibits this symptom :^)

#

i'll keep looking at the code and trying to find debug paths/solutions and let you know

fleet osprey Jul 21, 2024, 7:32 AM

I don't see any reason it shouldn't be
if I boot ventoy it says UEFI, and in the BIOS setup it says the boot mode is UEFI Native with no CSM

I can also select UEFI "Hybrid" w/ CSM, or Legacy mode

the issue is that Limine framebuffer is bugged, having the wrong pitch, only on 1366x768 mode, which is listed as ^^^^

Mint did you look at the values you're getting from it?

Just dump the video mode struct

And try overwriting pitch to native screen size * 4

i did that already

fleet osprey Jul 21, 2024, 8:29 AM

only requirement to make it break is it needs to either not specify a resolution, or force 1366x768

any other res works fine

it could be a massive coincidence

hell

you don't even need to draw a square

just draw a vertical line @analog berry

and don't tell me you don't know how

it's just x_pos + pitch * i

in a for loop

#

would you look at that

fleet osprey Jul 21, 2024, 9:20 AM

that is exactly 100% the same output, I'm nearly certain
I'm seeing the same patterns of pixels

craggy tide Jul 21, 2024, 9:20 AM

all i did was try 1366x768 on ovmf qemu

that one still supports 1366x768

#

well i guess having this reproducer is nice

#

nvm i'm stupid, no shit the problem only exists with ovmf lol

#

uhhhh

#

that pitch looks fine

#

the Limine template looks fine when it boots

#

it means it's some sort of drawing issue?

oh no wait

that changes the res

yeah okay

@fleet osprey does this look the same for you?

on the ProBook the actual kernel looks fine with this ^^^ template
idk when that changed, because it didn't initially, and didn't test that on the other ones, I just assumed it wouldn't work, since Limine's interface was busted

It's coherent, which is more than I can say about Limine's UI on there lol

craggy tide Jul 21, 2024, 9:32 AM

try drawing a white vertical line at x=1365

craggy tide Jul 21, 2024, 9:54 AM

#

ok so i think in qemu the screen is 1360

#

and actually reported wrong

#

hence why the minus 24 makes it work

#

and also why it breaks Linux and FreeBSD too

#

but their laptop, i have no idea

#

maybe checking the EDID, but idfk

flat copper Jul 21, 2024, 9:55 AM

#

maybe it's 1368? 1365?

#

but that sounds odd

craggy tide Jul 21, 2024, 9:55 AM

#

why would the default UEFI mode be broken

flat copper Jul 21, 2024, 9:55 AM

#

hmmm

#

idk

fleet osprey Jul 21, 2024, 9:55 AM

#

and why wouldnt it break in grub

#

or windows pe

#

or anything else

craggy tide Jul 21, 2024, 9:58 AM

#

that, i do not know

fleet osprey Jul 21, 2024, 10:25 AM

#

Just spent 30m trying to netboot that laptop, just to realize I already had Linux on it 😭
But yes, according to Xorg, it is in fact 1366x768, so I don't think UEFI is lying about it

aghhh I need the willpower to work on this

#

I have an old 2000s x86-64 computer laying around

#

its new enough to be 64 bit but old enough that it doesn't boot with uefi iirc

#

I should try to see if astral boots on that

#

some time

wild marsh Jul 24, 2024, 9:48 PM

#

i have a stack of 3 x86_64 laptops from around 2008 if you want me to test it on them

grand shadow Jul 24, 2024, 9:48 PM

#

I mean I don't expect it to work that much on real hw rn and I'd much rather test it somewhere I can easily debug

#

ty tho

neon crane Jul 24, 2024, 9:48 PM

#

same but i think i might try it regardless of whether math wants or not

grand shadow Jul 24, 2024, 9:49 PM

i mean on one of them managarm boots up fine into weston (off of ahci even)

grand shadow Jul 24, 2024, 9:51 PM

#

I'm gonna update the iso on avalios.dev to be the under the newest commit

wild marsh Jul 24, 2024, 9:51 PM

one has a slightly messed up madt and managarm doesn't like that (two ISOs for the same irq)

how messed up is it

wild marsh Jul 24, 2024, 9:52 PM

#

iirc there's 2 madt ISOs for pic irq 9

#

one with actual flags, and the second one that just says default flags

#

also it MCEs while booting linux but that's neither here nor there meme

grand shadow Jul 24, 2024, 9:55 PM

#

wild marsh one with actual flags, and the second one that just says default flags

I suppose in those cases if you even want to support machines like that you just have to use the one with actual flags?

wild marsh Jul 24, 2024, 9:56 PM

#

i guess? some time ago i checked what linux does in that case but i forgor

#

iirc it just doesn't care about the second entry?

grand shadow Jul 24, 2024, 9:57 PM

#

if it works it works

wild marsh Jul 24, 2024, 9:58 PM

#

wild marsh iirc it just doesn't care about the second entry?

i think the code might not have any checks for it and it reinserts the irq into the array but default flags just mean it doesn't overwrite whatever they already were so it works out

grand shadow Jul 24, 2024, 10:01 PM

#

well I copied the updated iso into https://avalios.dev/astral.iso if y'all want to try it

#

@wild marsh @neon crane

grand shadow Jul 24, 2024, 10:05 PM

#

grand shadow I have an old 2000s x86-64 computer laying around

thinking of it, it could be a pretty interesting way to test my shit on real hw
it has 2 dvd drives one connected to ide and one on sata, a floppy disk if I even feel like it and iirc several old internal hdds

#

just don't know if it even works, last time I powered it on was 2021 IIRC

wild marsh Jul 24, 2024, 10:05 PM

if i was really motivated i could grab an athlon 64 x2 computer from the attic to test :^)

I think thats the cpu in that computer

#

I have a spare ps2 keyboard and a spare screen, I could just leave it neatly set up in a corner and test it

#

yeah I think this weekend I'm gonna clean the dust off it and see if its working at all

wild marsh Jul 24, 2024, 10:26 PM

#

i'm starting to suspect something is wrong with the image

#

none of the 3 laptops even got into limine

#

all stuck on a blank screen with just the text mode cursor

#

also does not boot as a hard drive image in qemu...

#

@grand shadow

grand shadow Jul 24, 2024, 10:34 PM

#

wild marsh also does not boot as a hard drive image in qemu...

wtf

wild marsh Jul 24, 2024, 10:34 PM

#

qemu-system-x86_64 -cdrom astral.iso -enable-kvm -m 2G vs qemu-system-x86_64 -hda astral.iso -enable-kvm -m 2G

#

did you run limine bios-install astral.iso?

grand shadow Jul 24, 2024, 10:35 PM

#

I just uploaded the iso my makefile makes

wild marsh Jul 24, 2024, 10:35 PM

#

hmm

grand shadow Jul 24, 2024, 10:35 PM

#

doesn't work with -hda on qemu here too

#

does work with -cdrom

wild marsh Jul 24, 2024, 10:36 PM

#

hmm i wonder if i have any dvd i could burn the image to :^)

grand shadow Jul 24, 2024, 10:37 PM

#

I don't see why it wouldn't work tho

#

maybe it worked for me cuz I was using rufus or something?

wild marsh Jul 24, 2024, 10:38 PM

#

possible

#

also now that i think about it, i think only one of the laptops actually has enough ram to load the initrd

grand shadow Jul 24, 2024, 10:39 PM

#

I could send the minimal iso image which uses much less ram

#

70mb initrd

📎 astral.iso

wild marsh Jul 24, 2024, 10:43 PM

#

nice

#

i ran limine bios-install on the image and it now attempts to boot with -hda

#

but complains about a size mismatch

#

even though i did use the same version (?)

grand shadow Jul 24, 2024, 10:53 PM

#

techflash had managed to get it on an usb

#

@fleet osprey what did you use

fleet osprey Jul 24, 2024, 10:54 PM

#

for what
to put the ISO on a USB?

#

if UEFI you can just dd it

#

if BIOS and you're lucky you can also just dd it, but it's not garuanteed to work

wild marsh Jul 24, 2024, 10:55 PM

#

the instructions from limine barebones should work

fleet osprey Jul 24, 2024, 10:55 PM

#

I used Ventoy to boot the ISO from a filesystem (and works on everything), but it might have been what caused the issues with init failing to load on the machines where it got that far

wild marsh Jul 24, 2024, 10:55 PM

#

to make an image that should also boot on bios

fleet osprey Jul 24, 2024, 10:56 PM

#

wild marsh to make an image that should also boot on bios

it works fine on BIOS on a couple of machines when dd'd iirc
it's just because you're not supposed to do that with an ISO specifically, if I remember the issue correctly

wild marsh Jul 24, 2024, 10:56 PM

#

yeah but the instructions are specifically to make a hybrid image

#

that both works as an iso and a hdd image

grand shadow Jul 24, 2024, 11:05 PM

#

wild marsh the instructions from limine barebones should work

think I do use something derivated from that

neon crane Jul 25, 2024, 10:26 AM

#

@grand shadow hey, it seems like https://github.com/Mathewnd/Astral/blob/rewrite/kernel-src/io/block/nvme.c#L720 software progress isnt supported on QEMU

#

do you even use it for anything?

grand shadow Jul 25, 2024, 10:30 AM

#

Spec said to do something with it iirc

#

Pre-boot Software Load Count (PBSLC): Indicates the load count of pre-boot software. After
successfully loading and initializing the controller, pre-boot software should set this field to one
more than the previous value of the Pre-boot Software Load Count. If the previous value is 255,
then the value should not be updated by pre-boot software (i.e., the value does not wrap to 0). OS
driver software should set this field to 0h after the OS has successfully been initialized.

neon crane Jul 25, 2024, 10:36 AM

I see

neon crane Jul 25, 2024, 5:45 PM

@grand shadow oops

#

grand shadow Jul 25, 2024, 5:50 PM

neon crane

Yeah that happens cuz I try to map everything into the hddm including overlapping stuff

neon crane Jul 25, 2024, 5:50 PM

#

note: this is running on an Intel Pentium D, a CPU from like 2005 or 6

grand shadow Jul 25, 2024, 5:50 PM

#

I should fix that and send you a new iso when Im home

neon crane Jul 25, 2024, 5:50 PM

#

why do you need to map stuff into the HHDM anyway?

#

are you rebuilding all the page tables?

grand shadow Jul 25, 2024, 5:50 PM

Yeah

neon crane Jul 25, 2024, 5:51 PM

#

makes sense

analog berry Jul 25, 2024, 5:55 PM

Lol astral has been tested on more hw than mathew would want i feel like LuL

#

just because its so cool

neon crane Jul 25, 2024, 6:00 PM

#

#

on my other PC it looks like this

grand shadow Jul 25, 2024, 6:02 PM

#

32 bit hpet makes sense

#

Thats also on my todo list which I have been procrastinating with ftl lately

#

The 32 bit hpet and overlapping ranges thing also happened on some of techflash's computers so thats fix some of those as well

#

Wonder if theyd happen on that desktop of mine sitting around

neon crane Jul 25, 2024, 6:07 PM

#

what's the HPET used for here

#

in my instance, only for calibrating the APIC timer

#

or well, that was what nanoshell64 used it for, I don't support the hpet in boron (it's commented out)

grand shadow Jul 25, 2024, 6:12 PM

#

I use it for calibraring too but I also use it for keeping the time with some precision without needing to service an interrupt but that can be delegated to another timer easily

neon crane Jul 25, 2024, 6:36 PM

TSC :^)

fleet osprey Jul 25, 2024, 8:28 PM

grand shadow The 32 bit hpet and overlapping ranges thing also happened on some of techflash'...

iirc they're of about the same ages too
HPET issues was on my ThinkPad T14 Gen 1 AMD
VMM issues was on my Dell Optiplex 755 (Core 2 Duo E8400, circa 2007)

neon crane Jul 25, 2024, 8:33 PM

fleet osprey iirc they're of about the same ages too HPET issues was on my ThinkPad T14 Gen 1...

similar issues as me huh

fleet osprey Jul 25, 2024, 8:34 PM

#

well, you didn't spark a multi hour long debug session the ended in the fixing of multiple video bugs on Limine, and the conclusion that the HP ProBook 4540s in UEFI specifically, has busted video modes

#

so you're having better luck than me so far

craggy tide Jul 25, 2024, 10:17 PM

#

i am not done with debugging that for the record

#

the probook

craggy tide Jul 25, 2024, 10:18 PM

#

wild marsh even though i did use the same version (?)

yeah but it also needs to be built by the same toolchain

#

for obvious reasons

wild marsh Jul 25, 2024, 10:36 PM

#

okay fair i didn't actually think about that

grand shadow Jul 25, 2024, 11:13 PM

#

alright, I fixed the overlapping entries thing

#

now I need to see what I'm gonna do about supporting a 32 bit hpet or doing smth else entirely

grand shadow Jul 26, 2024, 12:25 AM

#

I'll do that tomorrow actually, I'm not going to uni so I'll be able to come home earlier from work

grand shadow Jul 26, 2024, 2:08 PM

#

I should also try to build gcc again now that the funny ext2 stuff has been fixed

neon crane Jul 26, 2024, 2:14 PM

#

woo!

grand shadow Jul 26, 2024, 2:36 PM

#

As for the 32 bit hpet support, making it so it increases once every nanosecond and getting an interrupt once it overflows (so around once every 4.3 seconds) doesnt sound too bad to be honest

neon crane Jul 26, 2024, 3:28 PM

#

grand shadow As for the 32 bit hpet support, making it so it increases once every nanosecond ...

Does the HPET do interrupts?

grand shadow Jul 26, 2024, 3:42 PM

#

neon crane Does the HPET do interrupts?

Yeah

neon crane Jul 26, 2024, 3:52 PM

#

Nice

grand shadow Jul 27, 2024, 10:37 PM

#

so qemu doesn't support FSB irqs

#

for the hpet

#

I want to support both legacy replacement and fsb as the 32 bit fallbacks

#

so I have to hope vmware or vbox support these

#

vmware supports fsb

I don't know if anyone who rolls their own kernel is going to have Wayland running

grand shadow Jul 27, 2024, 11:33 PM

#

managarm did

#

bruh they only added a -trace for hpet recently

#

I'm gonna have to compile qemu from source again, fun

#

might as well leave it compiling and go sort out dinner

grand shadow Jul 28, 2024, 2:12 AM

#

the legacy replacement irq routing is done, now for the fsb message stuff

grand shadow Jul 28, 2024, 2:48 AM

#

grand shadow vmware supports fsb

I think I had misread it cuz its not now

#

ah well should work on enough pieces of hardwaire with legacy replacement only

#

and if it doesn't I will curl up into a ball and cry

#

also @fleet osprey @neon crane, I fixed that vmm initialisation bug and support a 32 bit hpet now so if you feel like testing it again on those computers thatd be cool

📎 minimal.iso

#

w/ a full distro on the usual https://avalios.dev/astral.iso

fleet osprey Jul 28, 2024, 3:14 AM

oh sweet the full one is already updated? alr

btw I'll also retest that PS2 init code on the Precision since you said you weren't sure if it had the updated code or not last time

I never tested nvme on real hw, great that it at least initialises lmao

fleet osprey Jul 28, 2024, 4:25 AM

#

on Linux it seems like all of my key presses are coming from AT Translated Set 2 Keyboard, it reports a PS/2 keyboard as being connected, and I don't see any keyboard-looking devices on USB, so I'm fairly certain it's PS/2

#

but ig that makes sense, you did say PS/2 support is iffy

grand shadow Jul 28, 2024, 4:25 AM

#

Yeah

#

Qctually ps2kbd didnt even seem to grt called?

fleet osprey Jul 28, 2024, 4:27 AM

#

smh, I still can't get the image flashed with dd to boot on legacy BIOS
I even tried in Windows with rufus this time and says that it's "not compatible with ISO/File Copy mode", so it had to fall back to dd mode
one sec, let me break out the Ventoy disk again, because ig that's the only way I can try to see if it can boot on the OptiPlex

#

even if I might not be able to get to a root prompt

#

I can at least test if it crashes in the VMM like it did last time

#

well while I wait for that to copy, I'll try this out on the Precision, where it hung doing PS/2 stuff

#

Also doesn't boot in BIOS there, let's see if UEFI works first then I'll try it in BIOS with Ventoy when its done copying

grand shadow Jul 28, 2024, 4:32 AM

#

grand shadow Qctually ps2kbd didnt even seem to grt called?

Only way I can see this happening in the code is if it silently fails the self test by timing out, weird

#

I should add a print for that tbh
