Bananymous d941e6d70b General: Update README features and environment variables 2025-07-17 21:45:48 +03:00
Bananymous b65068dc7d BuildSystem: Add support for building initrd image 
This is nice for testing when there isn't xhci controller available or
my usb stack fails :)

Bananymous d5301508ec Kernel: Increase kernel thread stack size 
HACK HACK HACK

This is just to make banan-os boot on one razer laptop where AML
triggers a stack overflow :)

Bananymous 793cca423b Kernel: Fix system timer disabling 
I was actually not disabling system timer (HPET, PIT) when using lapic
timers for scheduling. This made BSB get too many timer interrupts :D

Bananymous 3960687f9d Kernel: Parse PCIConfig opregion address on read/write 
I was testing on some hardware and _ADR does not have to exist in the
namespace when opregion is parsed :)

Bananymous 3ec7aad432 Kernel: Increase PS/2 timeout and detect more keyboards 
I was testing on a old T61

Bananymous 995dfa1455 Kernel: Fix AML PCIConfig OpRegion accesses 
Apparently I'm not supposted to calculate device/function from the
offset, but parse them from the acpi namespace :)

This allows PCI PIN interrupt routing actually work

Bananymous 544c8dbc13 Kernel: Optimize AML interpreter stack usage 
There is a very hacky no-inline hack that I am not proud of but it drops
the stack usage of few functions A LOT.

Previously Virtual Box could not boot with our 8 page stack, but these
changes allow it to boot on 5!

Bananymous 8da4f80453 Kernel: Add custom stack to double fault handler 
This prevents triple faults!
 2025-07-02 23:14:52 +03:00
Bananymous 6084aae603 Kernel: Add guard pages to kernel and userspace stacks 2025-07-02 23:12:36 +03:00
Bananymous e1319a06f2 Kernel: Remove accidentally commited debug prints 2025-07-02 23:09:57 +03:00
Bananymous 51fd7a607d Kernel: Fix IDE controller waiting 
We did not correctly wait until controller is ready to receive data on
write command. Also remove possible kernel panic if controller sends
unexpected interrupts
 2025-07-02 22:04:41 +03:00
Bananymous 8aff315c7b LibC: fflush file in setvbuf before updating the buffer 2025-07-02 01:54:03 +03:00
Bananymous 8e0d79f301 ports: Fix `make` compilation with new toolchain 2025-07-02 01:54:03 +03:00
Bananymous 8a0269d29e Kernel: Remove kernel processes 
Kernel can just use raw threads, pretty muchs the only thing that
process provides is syscalls which kernel threads of course don't
need.

Also this makes init process have pid 1 :D

Bananymous 892e16dfb1 Kernel: Increase PS2 timeout to 300 ms, load PS2 in separate thread 
PS/2 seems to hit command timeout sometimes on slow emulation so
increase the timeouts.

Also move PS/2 device initialization to a different thread because
device indentification waits for timeouts.

Bananymous 92e4078287 Kernel: Rewrite ThreadBlocker 
This gets rid of a very old bug where kernel panics when thread is being
woken up and unblocked at the same time on different cores. This
required adding a new lock to SchedulerQueue::Node and adding a cap to
how many threads a threadblocker can simultaneously block. I don't think
I ever block more than five threads on the same ThreadBlocker so this
should be fine.

Bananymous 41e1819072 Kernel: Align argv and envp to pointer boundary 
This bug was found with ubsan
 2025-07-02 00:17:42 +03:00
Bananymous fb7e9719a1 Kernel: Add fast fill method to framebuffer device 
This makes `clear` much faster when running without kvm!
 2025-07-02 00:17:42 +03:00
Bananymous c2d09b64ca Kernel: Drop 24 bpp support from double buffer 
I don't even know why this was supported, I am not planning on making
the fb anything other than 32 bpp
 2025-07-02 00:17:42 +03:00
Bananymous 1b2aa6c2da Kernel: Fix unaligned access in AML 
Found with ubsan
 2025-07-02 00:17:42 +03:00
Bananymous a5b4cee298 Kernel: Load USTAR from a boot module if loading root partition fails 
This allows banan-os to boot on hardware where we don't have working
storage driver or the storage driver fails (pretty common with my usb
mass storage drivers...)

Bananymous 17f1ac10e3 Kernel: Don't ignore modules passed with multiboot2 2025-07-02 00:17:42 +03:00
Bananymous c67198032f Kernel: Rewrite TmpFS block and inode allocation 
This makes creating files and appending to then A LOT faster. Some code
I tested took 40 seconds in the previous implementation and less than a
second on the new one!

This code is really sketcy, I hope I'll never have to touch it again :)
