Bananymous e0011d22f2 Kernel: Move ACPI to its own directory and namespace 2024-04-04 15:00:13 +03:00
Bananymous 89ca4c8a8b Kernel: Implement IPI broadcasting 2024-03-09 23:53:38 +02:00
Bananymous 23a2f8b903 Kernel: Cleanup multiprocessor startup by removing magic numbers 2024-03-07 17:01:17 +02:00
Bananymous 29fd682672 Kernel: Store current processor pointer in IA32_GS_BASE 
This allows easier access to processors fields
 2024-03-07 16:05:29 +02:00
Bananymous 8141b9977d Kernel: Per processor information is now stored in class Processor 
This allows us to allocate processor stacks, and other per processor
structures dynamically in runtime. Giving processor stack to
ap_trampoline feels super hacky, but it works for now.
 2024-03-03 22:30:06 +02:00
Bananymous c035d3c82c Kernel: Start all processors on kernel boot 
Processors don't do anything, except print hello message and halt.
 2024-03-03 02:19:43 +02:00
Bananymous 18253b6966 Kernel: Replace InterruptController CriticalScopes with SpinLock 2024-02-29 19:15:33 +02:00
Bananymous d94f6388b7 Kernel: Fix all broken locks from new mutexes 2024-02-28 22:45:34 +02:00
Bananymous dfe5a2d665 All: Cleanup all files 
Add newline to end of files and remove whitespace from end of lines
 2024-01-24 15:53:38 +02:00
Bananymous c6130f33d7 Kernel: Implement MSI, MSI-X and interrupt reservation 2024-01-13 18:21:21 +02:00
Bananymous 888e44ce0b Kernel: Allow getting ACPI headers with same signature 2023-10-13 11:24:21 +03:00
Bananymous 27eb5af6f0 Kernel: Rework interrupt mechanism 
All interruptrable classes now inherit from Interruptable which
has methdo handle_irq which is called on a interrupt.
 2023-10-05 18:53:45 +03:00
Bananymous 4842d5e2b9 Kernel: APIC now uses MMIO namespace functions for mmio 2023-08-10 21:07:23 +03:00
Bananymous 3139391e06 Kernel: Change PageTable API 
Getting free pages not reserves them, so you don't have to hold
the page table lock :)
 2023-08-02 22:09:14 +03:00
Bananymous 4086d7c3be Kernel: rework the whole PageTable structure 
We now have page table structure for kernel memory which is shared
between all processes.
 2023-07-05 23:41:35 +03:00
Bananymous 5bb1f2a48c Kernel: Rename MMU to PageTable 
This is more descriptive name for what it actually represents
 2023-05-29 21:06:09 +03:00
Bananymous 869de7283f Kernel: MMU::get() is now MMU::kernel 
MMU is can now be locked with RecursiveSpinLock.

Scheduler now has get_current_tid() that works before the Scheduler
is initialized. This allows RecursiveSpinLock usage early on.
 2023-05-28 16:18:18 +03:00
Bananymous 55bb0084aa Kernel: namespace and function renames 
MMU moved to namespace kernel
Kernel::Memory::Heap moved to just Kernel
MMU::map_{page,range} renamed to identity_map_{page,range}

Add MMU::get_page_flags
 2023-04-28 14:48:38 +03:00
Bananymous 0030f035be Kernel: Rename MMU::{un,}allocate... to MMU::{un,}map 
This is more appropriate name for the behaviour :D
 2023-04-19 21:50:30 +03:00
Bananymous 88f60b5e41 Kernel: Map all ACPI tables on initialization 
This makes their usage much easier and less error prone

They won't mapped be processes when we get to there, so this won't be
a problem
 2023-04-18 10:18:15 +03:00
Bananymous fdb4eb6042 Kernel: Move kmalloc and MMU to Memory directory 2023-04-18 10:18:15 +03:00
Bananymous c7286396d8 Kernel: Move ACPI to its own file 2023-03-27 17:30:45 +03:00
Bananymous 2e6e0d0ef5 Kernel: FIX ubsan complaining about unaligned addresses for STDHeaders 2023-03-08 22:55:44 +02:00
Bananymous 8a52c0f9d7 Kernel: Cleanup RSDP parsing code 2023-03-07 00:41:13 +02:00
Bananymous 9756de02ef Kernel: MMU now takes flags when allocating pages 2023-03-01 21:21:56 +02:00
Bananymous 9b8de5025a All: rename every function from UpperCamelCase to snake_case 
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)
 2023-02-01 21:05:44 +02:00
Bananymous 6dc22b7251 Kernel: Add actual register values to x86_64 kernel panic 
Very hackish implementation, but we now get actual registers at the
time of the interrupt happening
 2023-01-30 18:52:38 +02:00
Bananymous bfe3426f6d Kernel: Add processor dump flag to APIC 2023-01-26 13:13:46 +02:00
Bananymous e00d18029d Kernel: rewrite some of APIC since it didn't work with xsdts for some reason 2023-01-26 02:57:14 +02:00
Bananymous c0bc002ac6 Kernel: Move debug printing to its own file 
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized
 2023-01-25 22:51:42 +02:00
Bananymous 48348c9e57 Kernel: Cleanup APIC code. Remove unnecessary defines and add consts 2023-01-25 19:00:41 +02:00
Bananymous ba53582f23 Kernel: Rewrite APIC and PIC more OOP friendly 
x86_64 port is slowly coming together
