Bananymous 26922ebb51 Kernel: Remove stack size check for keyboard layout initialization 
Keyboard layout loading can take around 1 KB of stack for i686 target
 2024-04-22 21:11:04 +03:00
Bananymous 7480e71801 BuildSystem: Download binutils and gcc as tar balls 
I am not sure why I changed this earlier. This is much cleaner and
faster as git doesn't have to recieve all patches and resolve deltas

Bananymous 9ac3f48fcb Bootloader: Implement better memset and memcpy for 32 bit addresses 2024-04-20 18:14:05 +03:00
Bananymous 0e405755ad General: Update README badge 
Tokei's own badge was kind unreliable and slow. I now parse the tokei output into json on server side and make shields.io query it.

Bananymous 34b10f61ce Kernel: Make PIT reserve its IRQ 
PIT did not reserve IRQ leading to kernel panic if it was being
initialized.

Bananymous b268293402 Kernel: Fix Buffer evaluate and store for sizes >= byte 
All reads and writes were to the first byte. This patch adds the

Bananymous f9943b60e4 Kernel: Fix mutex try_lock return value 
WHY IS GCC NOT COMPLAINING FROM HEADERS... I used almost 2 hours
trying to locate why AML was broken
 2024-04-17 01:16:43 +03:00
Bananymous f97fb1b35d Kernel: Evaluate _REG on devices for embedded controller if needed 2024-04-17 01:16:43 +03:00
Bananymous b959181afd Kernel: Remove ACPI namespace from itself 
This removes unnecessary cyclic reference
 2024-04-17 00:52:05 +03:00
Bananymous cbc27a94ac Kernel: AML cleanup IfElse code 2024-04-17 00:49:07 +03:00

 2024-04-16 17:36:04 +03:00
Bananymous f1b2d7530d Kernel: Rework AML namespace and object hierarchy 
Remove tree-like structure from AML. This allows more spec compliant
parsing of named objects inside not yet declared devices.

This also allows AML to be run thread safely. All object adds/removes
are now guarded by a mutex.
 2024-04-16 16:47:45 +03:00
Bananymous b6587b32b9 Kernel: ACPI ignore events from non-existent ports 2024-04-16 00:00:07 +03:00
Bananymous b89bafa165 Kernel: Add support for power button shutdown 
This patch implements basic support for power button using ACPI
fixed events. I still need to implement general purpose events
and embedded controller for full power button support.
 2024-04-15 23:55:25 +03:00
Bananymous 9fac5f94ba Kernel: Fix entering ACPI mode 
My condition to check wheter to enter ACPI mode was incorrect.
I only entered ACPI mode if I already was in ACPI mode :DD
 2024-04-15 15:05:48 +03:00
Bananymous 5affc73ee6 Kernel: Parse ACPI namespace only after TTY is initialized 
This allows better debugging when there is no serial port available.
 2024-04-12 16:47:17 +03:00
Bananymous 027016ddae Kernel: Load all SSDTs and PSDTs 
Spec says to load all tables with unique OEM table IDs but that seem
wrong.
 2024-04-12 16:45:00 +03:00
Bananymous 8f2f98b7b4 Kernel: AML implement SleepOp 2024-04-12 16:17:14 +03:00

Bananymous 74940ed33c Kernel: Cleanup AML code and fix bugs 
I can enter ACPI mode on my own laptop!
 2024-04-12 16:03:14 +03:00
Bananymous 17871bb3ca Kernel: Fix ACPI namespace initialization 
ACPI spec says that only SSDTS with unique OEM table IDs are to be
loaded.

Add loading of ACPI 1.0 PSDTs

Bananymous 89c4abc07a Kernel: Cleanup AML device initialization 
_STA and _INI are now properly called on call devices
 2024-04-12 02:00:30 +03:00
Bananymous 46b5a7697c Kernel: Implement dummy \_OSI method for AML 
This always returns Zero (not supported)
 2024-04-12 01:49:54 +03:00
Bananymous dd8060d64f Kernel: Add FieldElement access attribute for AML interpreter 2024-04-12 01:49:15 +03:00
Bananymous afb1d7ef0c Kernel: Implement more features for AML parser/interpreter 
Added
   - BankField
   - BufferField
   - PowerResource
   - ThermalZone
   - Reference
   - Package element forward declare
 2024-04-12 01:47:40 +03:00
Bananymous 93ddee5956 Kernel: Implement locking for AML 
Now global lock uses the actual global lock. Currenly if no lock
can be acquired, we just panic the kernel so that I remember to
implement it properly once AML is running concurrently.
 2024-04-11 01:48:46 +03:00
Bananymous 0184e5beb5 Kernel: AML tries to initialize processors when entering ACPI mode 
I had forgotten that Processors used to be a different definition
in AML.

I also implemented reads/writes for FieldElement/IndexFieldElement
that fit in 64 bits. Reads and writes to buffer are still a TODO.
 2024-04-11 01:48:46 +03:00
Bananymous 3f2e110eab Kernel: Entering ACPI mode now actually enables ACPI 
I used to only initialize devices, but now I send ACPI_ENABLE if
machine is not hardware reduced.
 2024-04-11 00:17:03 +03:00
Bananymous 0ff68b7d66 Kernel: Make ACPI load all SSDT headers after DSDT is loaded 2024-04-10 15:03:54 +03:00
