 2024-09-12 23:55:34 +03:00
Bananymous 467ac6c365 Kernel/LibC: Implement SOCK_CLOEXEC and SOCK_NONBLOCK 
This removes the need for fcntl after creating a socket :)
 2024-09-11 21:59:11 +03:00

Bananymous 64a3893f6f Kernel: Add command line option to disable AML parsing 
This can be handy if my broken AML parser crashes or hangs while parsing
AML :D
 2024-09-10 16:20:24 +03:00
Bananymous eabe759ebf Kernel: Don't require APs that are not started to start :D 2024-09-10 16:19:43 +03:00

Bananymous de35cec2e1 Kernel: Allow private file mappings past file end 
This is just to make memory mapping ELF files easier :D
 2024-09-05 14:48:42 +03:00
Bananymous 2f241e1b61 Kernel: Implement FileBackedRegion::clone 2024-09-05 13:59:09 +03:00

Bananymous 827eec6af0 Kernel: Make .rodata read-only and add -orphan-handling=error 
I don't really know why .rodata was marked writable :D
 2024-08-30 15:33:02 +03:00
Bananymous 8da2f12ba6 Kernel: Only load program headers of interpreter if its present 
I was loading program headers of both executable and interpreter but
that is incorrect. The interpreter will itself load the program headers
of the executable.
 2024-08-28 21:19:37 +03:00
Bananymous 2bf65ef512 Kernel: Invoke ELF interpreter instead if it is specified 2024-08-28 17:06:32 +03:00
Bananymous d20752c318 Kernel: Make OpenFileDescritorSet::open take rvalue 
This gets rid of some implicit allocations from copy constructors
 2024-08-28 16:36:10 +03:00
Bananymous 5f66ef34dd Kernel: map userspace arguments after the entry point 
This allows cleaner memory layout for processes that are not loaded to
default location
 2024-08-27 22:46:08 +03:00
Bananymous da0b4cd40e Kernel: Allow MAP_FIXED in mmap 2024-08-27 22:45:49 +03:00
Bananymous 2c520391eb Kernel/LibC: Add support for init_array and fini_array 2024-08-27 00:47:03 +03:00
Bananymous 7c4b9218f2 Kernel: VirtualTTY now resets ansi state before printing anything 2024-08-25 17:56:06 +03:00
Bananymous 72f8138ca1 Kernel: Disable scheduler load balancing until I get it fixed 
Scheduler keeps crashing all the time when running on multiple cores.
This patch disabled the load balancer, which seems to get rid of most
scheduler crashes.
 2024-08-25 15:37:17 +03:00
Bananymous 991ae4383a Kernel/LibC: Implement fchmod 2024-08-25 15:07:42 +03:00
Bananymous 2ce7205c80 Kernel: Add command line option to disable debug printing 
The whole system can crash when debug output and tty output are done at
the same time. This patch is just a hack to prevent the crash :D
 2024-08-25 15:02:15 +03:00
Bananymous fb35f06cf5 Kernel: Add better support for bootloaders loading the kernel 
Before I assumed that bootloaders loaded the kernel at physical address
0, but this patch kinda allows loading to different addresses. This
still doesn't fully work as kernel bootstrap paging relies on kernel
being loaded at 0
 2024-08-22 14:48:21 +03:00
Bananymous abc788c756 Kernel: Improve output message when dumping all syscalls 2024-08-22 14:48:21 +03:00
Bananymous 63b616dc2e Kernel: Hack non-blocking support for sockets 
This is not thread safe and can still block if two programs refering to
the same socket try to read data at the same time
 2024-08-22 14:48:14 +03:00
Bananymous cba12efeb1 Kernel: Ignore optional_actions in SYS_TCSETATTR 
Currently all terminals are syncronous, so the actions don't do anything
 2024-08-22 14:47:54 +03:00
Bananymous 37cd4ed504 Kernel: Add support for CSI @, b, d to VirtualTerminal 2024-08-22 14:04:45 +03:00
Bananymous 869bba4dad Kernel: Add check for panic in timer interrupt handler 
Previously processors would not get notified about kernel panic if they
were idling
 2024-08-22 14:03:03 +03:00
Bananymous 23194d1f53 Kernel: Implement basic random device to /dev/random 2024-08-22 14:02:26 +03:00
Bananymous 969563c06a Kernel: Don't load AP init code to 0xF000, but relocate it later 
This cleans up the kernel executable as bootloaders don't have to
load AP init code straight to 0xF000, but it will be moved there once
kernel is doing the AP initialization.

Bananymous 066e8e1cc2 Kernel: Remove unnecessary debug logging from VFS initialization 2024-08-18 20:51:10 +03:00
Bananymous 5cd7b40165 Kernel: Make BananBootloader info struct header compatible with C 2024-08-18 20:51:10 +03:00
Bananymous c7b134ba4b Kernel: Fix NVMe controller namespace numbering 
namespace numbers were incrementing globally instead of per controller.
This led to two single namespace controllers creating nvme0n1 and
nvme1n2
 2024-08-18 20:51:10 +03:00
Bananymous ff62c262fe Kernel: Fix PS/2 scancode set 2 keycodes for the bottom row keys 2024-08-18 20:51:10 +03:00
Bananymous 42e2c15e0c Kernel: Add ps2=<scancode set> command line argument 
This allows forcing specific scancode set on broken PS/2 emulations
 2024-08-18 20:51:10 +03:00
Bananymous 40c6989374 Kernel: Implement AML ObjectTypeOp 2024-08-18 20:51:10 +03:00
Bananymous 71dc373610 Kernel: "Fix" AML _OSI string to return true for windows strings 
This is the way its supposed to be done as other code paths are
untested...
