Bananymous 36baf7b0af Kernel/LibC/DynamicLoader: Update process start ABI 
We now use SysV abi for process startup
 2025-04-15 23:05:52 +03:00
Bananymous a0123e7c2d Kernel: save and load sse context in more spaces 2025-04-02 12:58:39 +03:00
Bananymous 2bf65ef512 Kernel: Invoke ELF interpreter instead if it is specified 2024-08-28 17:06:32 +03:00
Bananymous 0dd74e3c9d Kernel: Implement syscalls for i686 and cleanup x86_64 
This actually allows i686 to boot properly!
 2024-04-03 02:23:23 +03:00
Bananymous fe386fa819 Kernel: Implement thread start trampoline for userspace 
This is needed on i686 to set segment registers.

Bananymous 2106a9e373 Kernel: Rework scheduler/processor stacks. 2024-04-02 12:34:42 +03:00
Bananymous 5050047cef Kernel: Rewrite whole scheduler 
Current context saving was very hacky and dependant on compiler
behaviour that was not consistent. Now we always use iret for
context saving. This makes everything more clean.
 2024-03-29 18:02:12 +02:00
Bananymous 2dd0bfdece Kernel: Make i386 thread tramplines crash 2024-03-26 00:10:42 +02:00
Bananymous fe17958b9f Kernel: Rename rsp->sp and rip->ip 
This makes more sense if we support i386
 2024-03-22 15:41:15 +02:00
Bananymous 896b919c9d Kernel/LibC: pass environ pointer to process 2023-06-05 21:12:08 +03:00
Bananymous e0a72defa2 Kernel: Add argc and argv to process entry 2023-05-16 00:27:49 +03:00
Bananymous ec316391c5 Kernel: argc is passed as zero to userspace 2023-05-11 18:28:32 +03:00
Bananymous 8ee63f8264 Kernel: We can create basic userspace processes 
These are still allocated on the kernel memory
 2023-04-12 17:52:36 +03:00
Bananymous f924ac9265 Kernel: Threads can now be terminated mid execution 2023-04-10 21:07:25 +03:00
Bananymous 3f01f936a1 Kernel: Fix framepointers on started threads 2023-04-10 21:07:25 +03:00
Bananymous af854ec9e1 Kernel: Thread creation now takes void(*)() as entry and void* as data 
This simplifies threading for the future and gets rid of (undefined?)
cast of member function pointer to address
 2023-03-09 15:33:42 +02:00
Bananymous 1dd61e93b6 Kernel: Threads cannot take arguments anymore 2023-03-02 01:56:09 +02:00
Bananymous 1bd8b0fe5c Kernel: Sleep now actually sleeps and allows idling 2023-02-19 18:52:25 +02:00
Bananymous 6fab26692b Kernel: remove unnecessary function from x86_64 Thread.S 2023-02-02 23:48:18 +02:00
Bananymous 5b5e620d8a Kernel: Improve multithreading support 
We can now use arbitary BAN::function<void(...)> as the Thread.
I also implemented multithreading for i386 since it was not done
on the initial multithreading commit.
