rigid fable
im getting annoyed at myself cause i always write shitty code
one reason you do so because you are trying to make it work without stopping for a second and thinking about the best way to implement it. Before even writing code, design it, then code it following that design. If it does not work instead of ditching the design continue by following it further.

OKAY IMAGE LOOKS VALID RIGHT?
IT LOOKS LIKE A VALID ADDRESS
lemme dereference the data
yep 0xbb as EXPECTED
OKAY AND THE ENDING ADDRESS
LOOKS VALID
LOOKS CORRECT RIGHT?
thats the limit
hmmm doing this causes this
how???
so memsetting causes this
for some reason memsetting img is causing something to happen to the framebuffer
huh????
like what?????
wicked loom
are you sure your pmm isn't perhaps allocating pages of the framebuffer as free?
or more generally, anything not usable
surreal path
are you sure your pmm isn't perhaps allocating pages of the framebuffer as free?
let me check
CAUSE THIS SHOULDNT HAPPEN AT ALL
yea?
same thing when calculating the hhdm?
so something weird is very much happening
VERY weird

i miss too much code to tell

your screenshots are incomplete
okay one second
for calculating the hhdm limit in my vmm ^
surreal path
just upload all your code somewhere
okay ill like put everything onto github
se

sec
surreal path
it has to be how im calculating my vmm hhdm limit
because the framebuffer address wouldnt be outside the hhdm right????
RIGHT????
UMM???
yea thats correct???
so why is it calculating the hhdm limit wrong
surreal path
Whats hhdm limit
hhdm limit is the end of the hhdm mappings
in the virtual address space
this is what should be expected
but for some reason
calculating the hhdm limit seems to not be working properly
ionic jetty
I noticed that you dont count reserved pages in vmm.c:vmm_init(void)
Is that related maybe?
surreal path
I noticed that you dont count reserved pages in vmm.c:vmm_init(void)
no cause
For base revision 0, the above-4GiB identity and HHDM mappings cover any memory map region.
For base revision 1, the above-4GiB HHDM mappings do not comprise memory map regions of types:
Reserved
Bad memory
limine spec says
the hhdm mappings in base revision 1 do NOT include reversed
ionic jetty
I thought thats supposed to mean limine doesnβt map them
surreal path
I thought thats supposed to mean limine doesnβt map them
huh??
ionic jetty
/ doesnt setup page map entries for these areas
if theres usable - reserved - usable areas the end of the second usable area is still at usable1.length + reserved.length + usable2.length
reserved just means that theres acpi tables there for example
instead of ram
tawdry mirage
well acpi tables are usually acpi reclaimable or acpi nvs :^)
surreal path
well acpi tables are usually acpi reclaimable or acpi nvs :^)
which i do count
tawdry mirage
reserved is stuff like bad ram, stolen memory, mmio, etc
ionic jetty
well acpi tables are usually acpi reclaimable or acpi nvs :^)
i wanted to make a point here : )
but yeah mb
surreal path
reserved is stuff like bad ram, stolen memory, mmio, etc
so i still gotta calculate reversed too?
ionic jetty
yes
surreal path
okay makes sense
surreal path
that solved everything
no weird framebuffer fuckery
time to test with flanterm now
!
ionic jetty
reserved is stuff like bad ram, stolen memory, mmio, etc
by stolen memory you mean like bootloader stolen memory? since that has its own memmap entry type afaik
or are you referring to smth else

but yeah why not have some fun in between
yea
wicked loom
yeah, the point is to have a seamless transition between the bootloader's console and the kernel console, preserving the wallpaper, margins, font, scaling, and everything; all the parameters flanterm needs
elder shoal
the real benefit I'd imagine is that you won't need to resize the image data to use for the background since the bootloader already did that
kind root
why is this transition needed?
elder shoal
but then you can also set for the bootloader and kernel to boot into different resolutions so

has a feature been proposed to allow smp cores to not go crazy before enabling them
to like put them to sleep
and make them interruptible
to wake em
wicked loom
no
that would involve loading an IDT on the parked cores
plus they don't "go crazy"
like sure they hit 100% but realistically only for a split second, and the pause mitigates any real power draw spike
ionic jetty
that would involve loading an IDT on the parked cores
so thats out of question for you?
wicked loom
no
i am just saying that that would be needed
and also pondering what would anyone gain from this feature
ionic jetty
i mean it would be a cool optional feature to enable if you want to test on smp systems without having smp support for example
surreal path
man i suck at designing logos
ionic jetty
i mean it doesnt really provide anything
but i just thought it could be nice
up to you : )
wicked loom
i mean it would be a cool optional feature to enable if you want to test on smp ...
but for that you can like
not have the SMP feature
lol
if you don't support SMP why would you have the feature, right?
and if you have the feature and simply never spin the cores up for whatever reason, at that point it's kinda on you
ionic jetty
okok stop being right i just thought it may be nice
obviously its not gonna add a lot of value
wicked loom
hey i am not trying to be right
i am trying to understand the use case
before i go and add it
and here it seems pretty redundant
ionic jetty
i dont know any excpet for reducing cpu load while not having provided the cores with their function pointer
it just bothered me a bit when I ran on real hw wihtout smp
that my pc went to like 60% power usage
which surprised me since I thought that pause calms it down more
wicked loom
it depends on the uarch
elder shoal
cant you just tell them to go to a cli hlt loop or something
wicked loom
and you also have to keep in mind that it's only meant for small durations
elder shoal
inside the kernel
ionic jetty
sure
ionic jetty
it was just an idea i'll just admit it isn't very useful okay 
wicked loom
it's okay
i actually love discussing this
and trying to figure out if there may be a reason to do things differently or add new features
forgive me if i sound like i am trying to shoot the idea down, i kinda am
that's the whole point, shoot ideas that don't add much value down (after considering them of course)
else we'd end up with a trillion features and 99% of them redundant
elder shoal
ntfs on limine pls
kind root
that my pc went to like 60% power usage
how do u even track this
wicked loom
which is also why i am happy when people try to shoot my ideas down like what i mentioned earlier with the thing
kind root
anyway pause is not enough lol
p/c state management is what u need
thats a lot of complex code
ionic jetty
how do u even track this
i dont but it got hot and the fans went crazy, 60% is a guess
wicked loom
pause is better than no pause
surreal path
man i suck at logo design
wicked loom
it's only meant for a very short duration of time
ionic jetty
thats a lot of complex code
well yeah thats bloat for a bootloader anyways
kind root
thats my opinion about smp in a loader anyway, but yes
wicked loom
like realistically, even without pause altogether it shouldn't be relevant when the kernel is supposed to spin cores up in a split second
but pause does actually reduce power consumption quite a bit

wicked loom
i talked to people in the industry
they say the main thing it could do is alleviate validation cost/time; but whatever it is i do not believe it is worth breaking backwards compat for

but that's my personal belief
wicked loom
if they really wanted to go all out they should just redo the encoding :^)
i do agree
if you're gonna do X86S then ditch x86 entirely
i'd rather see Intel move to making ARM chips or whatever
tawdry mirage
i mean you can keep the source-level asm syntax but just reorganize the encoding so things aren't as long
e.g. REX
tawdry mirage
i mean an extra byte because you want a 64-bit operation and not a 32-bit one kinda stings
esp because byte/{,d}word is baked into the opcode for some instructions
wicked loom
it's still comparable in density to aarch64
tawdry mirage
yeah the average density is about the same as on aarch64
i've seen 4 vs 4.5 bytes/instruction for aarch64 and x86 respectively mentioned, but i have a feeling that those figures fail to account for constant pools you end up needing on aarch64
for 32-bit value constant loads or whatever
wicked loom
X86S is literally just "x86 but we now hate legacy OSes so we refuse to run them despite the CPU still needing the same exact decoder anyways because we don't actually drop 32-bit compat mode"
it stinks
tawdry mirage
for 32-bit value constant loads or whatever
mov eax, 0x11223344 is 5 bytes but ldr x0, =0x11223344 is 8 bytes total (because it's actually a pc-relative load from a constant pool)
cinder plinth

I finally ran sudo apt update on my wsl install and 229 packages can be upgraded. Run 'apt list --upgradable' to see them.

You can do it from an arch install????
you can do it from anywhere, since the install instructions basically tell you to set up partitions, and download and extract the rootfs tarball onto the new root fs
as long as you can chroot into it
i did have to reboot into a liveiso to shrink the arch partition originally, but after that i just rebooted back into arch to do the actual install

do yall think I should spend the next few days setting up gentoo or use fedora and just work on Nyaux
surreal path
i was joking
no Iβm genuinely considering it
finite summit
The best linux distro is obviously debian
surreal path
I think honestly what Iβm gonna like do
is just try setting up gentoo cause I rlly like gentoo
Even if it takes me days

another one bites the dust...

just use fedora lol
fedora works okay
surreal path
so you'll end up getting so busy on compiling packages
My CPUβs fast
I compiled the entire Linux kernel in like
20 minutes
kind root
u didnt compile the entire kernel
u compiled whatever subset of drivers was selected in your config
kind root
anyway i wouldnt waste days on this
surreal path
π
kind root
cant think of a more boring thing
finite summit
making a distro of the NT kernel is probably more amusing if you like reverse engineering
Actually
finish NyaUX
and make your PC run it
surreal path
ah yes
kind root
finish NyaUX
let him get back to you in 50 years
finite summit
anyway
I got dumb stack corruption bugs to deal with
and memory corruption
and scheduler bugs
kind root
i thought u had asan
surreal path
Go fix em
finite summit
Turning on ASAN causes them to happen
kind root
bro
finite summit
except for the scheduler bug
kind root
how do u even manage to produce so many bugs
finite summit
I'll boot into my kernel, and debug the first of the bugs that comes at me
finite summit
how do u even manage to produce so many bugs
Skill issues mainly
kind root
lol
finite summit
stack traces are also fucked so I can only know up to one frame of the stack
a lot of my debugging now is guess work
kind root
fix them
kind root
yes
finite summit
This time
kind root
have you grown as a coder
kind root
good idea
finite summit
I'll try to get a UBSan and ASAN as soon as possible
So I have more possible ways of testing
and detecting bugs
anyway enough cluterring this thread
I'll say any progress on the bug in my thread

i wanted to do that at some point but i have absolutely no clue how windows even starts up and it would be a fuck ton of reverse engineering which im not very good at so i just gave up after thinking about it for a while lol
finite summit
also microsoft probably wouldn't be very happy if you did that
thorn bramble
why
im just writing code
im not publishing their code or doing anything illegal
i am almost 100% sure that it would be just fine
it would probably be very useless but whatever

on my latest exams that I took last week and the week prior to that, I didn't even study, I'd just study 1 class before it and I got 10/10 in almost every test
surreal path
I KNOW ITS BEEN A FEW DAYS BUT IM BACK !!!!!
I ONLY HAVE LIKE 1 EXAM LEFT !!!
TOMOROOW AND THEN I CAN WORK ON NYAUX
π
also i got gentoo working as well
π
(idk why it uses so much ram at idle, even with just the tty it takes like 300-400mb of ram? must be because i didnt compile the kernel and just used the gentoo dist bin kernel)
surreal path
gonna try booting nyaux on real hardware for the lols
rigid fable
also i got gentoo working as well
4gb ia way too much
rigid fable
you might as well use Windows 10 with wsl if you are fine with such memory consumptions
surreal path
ima fix by compiling my kernel
rigid fable
yea idk why
search on the internet, else change distro
surreal path
why wont uacpi compile π undefined reference to `__popcountdi2'
grrr
it worked on wsl!
what tf does this mean
surreal path
im looking
like wait
ok fixed π
adding the option -march=x86-64-v2
fixed it
bro...
it worked on fkn wsl
what tf is going on
what da flip
why is it giving me an address from the hhdm
what the flippers
surreal path
presumably you have a different compiler version than you had on wsl?
idk i guess?
i dont know why this is happenin tho
this makes no sense !
what???
what the fuck?
ummmm
interesting
umm why is uacpi giving me this bogus size
kind root
did u enable sized frees or are u just reading an uninitialized register
surreal path
did u enable sized frees or are u just reading an uninitialized register
i enabled sized frees
kind root
u have a function with that signature, that doesnt mean u enabeld it
thats not how this works
kind root
in a C file?
surreal path
yea
kind root
do u know how C works?
surreal path
oh i forgor
again
i know C works i just remembered this
again
im stupid
woopsies
oopsie
yea it works now
!!!
thanks copyobject abuser for reminding me of the same exact issue i had before i had completely forgot about !
kind root
np
surreal path
so get the madt?
surreal path
since u have uacpi `uacpi_table_find_by_signature(UACPI_MADT_SIGNATURE)`
where is uacpi_madt_signature defined?
surreal path
thanks
thorn bramble
when were the acpi table structures added?
i was looking for it a few days ago because i swear ive seen it
but i couldn't find it
kind root
just yesterday lol
thorn bramble
just a pointer to a pointer
kind root
^
surreal path
so i need to create a uacpi_table
kind root
yup
surreal path
ok cool
thorn bramble
i don't think you're supposed to free those btw
kind root
you dont
thorn bramble
as i thought, just something to keep in mind
kind root
yea
thorn bramble
it most likely is one
surreal path
i never knew!
kind root
I would check the return value but oh well
tawdry mirage
looks like
how tf are you living without a proper print function
surreal path
how tf are you living without a proper print function
serial_print π
tawdry mirage
`kassert(uacpi_table_find_by_signature(...) == UACPI_STATUS_OK);`
kassert might be a bad choice if it's removed with NDEBUG
tawdry mirage
serial_print π
which doesn't print to the screen...
kind root
Use it
surreal path
which doesn't print to the screen...
yea it prints to serial

i restarted my project today and first thing i did was add nanoprintf
lol
i should start a thread for my thing soon too i guess
kind root
i should start a thread for my thing soon too i guess
Do it rn
surreal path
it says that after the header theres the local apic address
thorn bramble
nah i dont have nearly enough to show
kind root
it says that after the header theres the local apic address
Look at acpi_madt
thorn bramble
uacpi gives you all the structures in acpi.h
kind root
And cast the table->virt_address
surreal path
ah okay π
thorn bramble
nah i dont have nearly enough to show
i'll post it when my memory allocator survives uacpi stress test :^)
kind root
That table is variable length and has a list of entries you will need to walk and record
surreal path
thats an address
kind root
Yea
tawdry mirage
yea it prints to serial
yeah my point is that you don't have any centralized logging
thorn bramble
btw don't use that lapic address, it doesn't reflect the actual value that's in the msr that's per core and might have been overwritten, shouldn't matter in most cases but it's probably the best to read it from there and mask off first 12 bits since it also contains some flags iirc
surreal path
That table is variable length and has a list of entries you will need to walk an...
huh?
steady flume
nya :3
tawdry mirage
the madt is a packed array of entries
which has lapic entries, ioapic entries, ISOs
surreal path
isos?
kind root
Interrupt source overrides
surreal path
what does that mean
kind root
Read the spec
tawdry mirage
pic irq number -> gsi
surreal path
Read the spec
spec in the sdm right
surreal path
ACPI represents all interrupts as βflatβ values known as global system interrupts.
i am not following
this is quite confusing but thats 5 lapics and 2 io apics
and whatever 192 is which acording to ACPI spec is a GIC Distributor (GICD)?
idk what that is
kind root
You fucked up the parsing lol
thorn bramble
make sure to increment the pointer by the size of the structure you're reading
kind root
Gic stuff is arm only
surreal path
make sure to increment the pointer by the size of the structure you're reading
im just doing this for loop
tawdry mirage
the combination x86 and arm machine
kind root
Bruh
tawdry mirage
im just doing this for loop
the entries are not all of the samee size
surreal path
im probs doing something stupid
thorn bramble
yes very wrong
surreal path
the entries are not all of the samee size
oh makes sense
β οΈ
is madt->entries->length in bytes?
or
surreal path
okay
thorn bramble
including all the entries and the header itself
kind root
it's the size of the entire table
Entries is an array
The length of the table is table.hdr.length
thorn bramble
aren't the entries inline?
thorn bramble
yeah but the length of the madt is the size of the header + all of the entries, right?
kind root
Yeah
thorn bramble
right that's what they asked
kind root
is madt->entries->length in bytes?
This is just wrong
surreal path
please tell me this is correct π
thorn bramble
yes that is correct
surreal path
okay
thorn bramble
it gives you the lengths of all entries in bytes
thorn bramble
now you need to iterate through them, the array starts at madt->entries and ends at (char*)madt->entries + length_of_entries
each iteration you need to advance by entry->length bytes
until you reach the end of course
surreal path
alr
thorn bramble
you can do something like this
size_t offset = 0;
while (offset < length_of_entries) {
struct acpi_entry_hdr *entry = (void*)madt->entries + offset;
// ...
offset += entry->length;
}```i guess i'm spoon feeding but eh
surreal path
i was doing something VERY cursed lol
kind root
Yup
surreal path
so we got 1 lapic
an ioapic
a bunch of "interrupt source overrides"
and a "local apic nmi"
whatever that and interrupt source override are
kind root
175 is probably wrong
surreal path
175 is probably wrong
bruh
uint64_t length_of_entries = madt->hdr.length - sizeof(madt->hdr);
size_t offset = 0;
while (offset < length_of_entries)
{
struct acpi_entry_hdr *ent = (void*)madt->entries + offset;
serial_print("WE GOT AN ENTRY!: TYPE!: ");
serial_print(itoa(wow, ent->type));
serial_print("\n");
offset += ent->length;
}
this is all im doing lol
