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 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 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 1b2aa6c2da Kernel: Fix unaligned access in AML 
Found with ubsan

Bananymous 81ff71a97f Kernel: Track the number of recursive spinlocks a thread is holding 2025-06-06 06:51:15 +03:00
Bananymous eecdad50a6 Kernel: Fix most of mutex + block race conditions 
All block functions now take an optional mutex parameter that is
atomically unlocked instead of having the user unlock it before hand.
This prevents a ton of race conditions everywhere in the code!

Bananymous 0e0d7016b3 Kernel: Rename has_hangup -> has_hungup 2025-05-17 12:39:23 +03:00
Bananymous 1bcd1edbf5 Kernel/LibC: Implement basic epoll 
This implementation is on top of inodes instead of fds as linux does it.
If I start finding ports/software that relies on epoll allowing
duplicate inodes, I will do what linux does.

I'm probably missing multiple epoll_notify's which may cause hangs but
the system seems to work fine :dd:

Bananymous 9f3f8f950a Kernel: Add better panic message for failed shutdown 
ACPI shutdown does not work on the web emulator and running `poweroff`
crashes on `ASSERT_NOT_REACHED()`.

Bananymous 3800d5420e Kernel: Collect created AML nodes in add_{named,alias}... 
This makes it harder to miss adding scoped objects. Before I was not
deleting all types of nodes on method return

Bananymous b145c1ab64 Kernel: Add easier api for evaluating ACPI nodes 2025-04-01 23:09:20 +03:00
Bananymous 83c66901f8 Kernel: Fix reboot when ACPI is disabled 
If ACPI was disabled ACPI::reset() would page fault when accessing
namespace instead of checking wheter namespace is initialized :D

Bananymous 82978da5e3 Kernel: Cleanup AML code 2025-01-17 16:20:00 +02:00
Bananymous a5cf92b2ff Kernel: Use uint64_t instead of size_t for AML node conversion 
This allows 32 bit to compile again :)

Bananymous d7b4f54983 Kernel: Check Control Method Battery _STA bit 4 
This bit indicates wheter the battery is actually present.

Bananymous 3a6cdfff45 Kernel: Fix ACPI namespace initialization 
Now _REG, _STA, _INI are called in the order my laptop expects them to
be called. This was kinda weird because what uACPI was doing did not
work.

\_SB_.PCI0.LPC0.EC0_.BAT0._STA required \_SB_.PCI0.LPC0.EC0_._REG to be
called
\_SB_.PCI0.LPC0.EC0_._REG required \_SB_.PCI0._STA to be called

Now I call all the _REG methods of a device after calling _STA/_INI and
after performing the whole _STA/_INI sequence i call rest of missing
_REG functions

Bananymous 4e364bd2f6 Kernel: Add support for ACPI Control Method Batteries 
The implementation is kinda weird but it exposes some battery
information to userspace!

Bananymous 869f4011a1 Kernel: Replace the old AML interpreter by a new, better one 
The old AML interpreter was trash and did not follow value/reference
semantics at all. It was also super slow, one of my machines taking over
7 seconds to parse ACPI namespace and call _INI and _STA.
