Bananymous f1c2284512 Kernel: Fix keyboard layout for underscore 2023-12-01 12:31:16 +02:00
Bananymous 1cfab4ae04 BuildSystem/Kernel: Enable -Wextra and -Werror in kernel 
Only needed to fix some unused variable bugs
 2023-12-01 01:22:53 +02:00
Bananymous 2ac28cba6e BuildSystem: Don't build lai with -Wstack-usage 
Lai has two functions that trigger warnings on gcc. There isn't
really anything I can do about it, so just disable the warning
 2023-12-01 01:22:53 +02:00
Bananymous ebe465e81e Kernel: cast between inheritance with static_cast 
using reinterpret_cast is not a good idea. preferably we would use
dynamic_cast, but that is not possible since kernel is compiled with
-fno-rtti.

Bananymous c10dffd719 Kernel: Make internal framebuffer bpp constexpr defined in libc 2023-11-29 20:07:33 +02:00
Bananymous 45d8d76e87 Kernel: Use the correct bpp when writing to framebuffer 2023-11-29 00:31:24 +02:00

Bananymous 0adb28e23f Kernel: Delete the now obsolete VesaTerminalDriver 2023-11-22 21:59:11 +02:00
Bananymous d4aa33b18b Kernel: Implement TerminalDriver for Framebuffer device 
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.

Bananymous 4ba3a17af3 Kernel: Add more APIs to FramebufferDevice 2023-11-22 21:56:27 +02:00
Bananymous e9d762892c Kernel: Implement basic framebuffer device 
This allows exposing framebuffer to userspace
 2023-11-22 20:34:41 +02:00
Bananymous 52807366bf Kernel: Make Ext2 filesystem use BlockDevice instead of Partition 2023-11-21 15:20:24 +02:00
Bananymous b437d4eb41 Kernel: TmpFS doesn't mark any functions as final 
I didn't think these would be overloaded, but they are
 2023-11-21 15:19:34 +02:00
Bananymous 8b7f3f1fb2 Kernel: Add common {read,write}_blocks() api to BlockDevice 2023-11-21 15:19:07 +02:00
Bananymous c607f5385e Kernel: Move Partition to its own file 2023-11-21 15:16:04 +02:00
Bananymous 5293ae070d Kernel: ProcFS inodes reflect processes ruid/rgid 
setgid/setuid did not change the permissions of procfs inodes. This
made Shell launched by init not appear in meminfo.
 2023-11-18 14:26:44 +02:00
Bananymous a312d75bb2 Bootloader: Implement VESA video mode query and pass it to kernel 
Kernel now gets framebuffer from bootloader. Framebuffer dimensions
and bpp are hardcoded in bootloader, but will probably be read from
config file at some point.
 2023-11-17 22:45:35 +02:00
Bananymous 065eec430e Kernel/Bootloader: banan-os can now be booted with my bootloader :D 2023-11-17 20:33:02 +02:00
Bananymous 41065d2f9a Kernel: Don't calculate divisor in a for loop in ext2 inodes 2023-11-17 19:02:01 +02:00
Bananymous 3daf3d53a3 Kernel: Serial now uses random size for some serial ports 
If the serial port doesn't repond with a size, just use a random
one. There is no reason to ditch the whole output if you cannot
determine its size.
 2023-11-17 18:56:02 +02:00
Bananymous ec56e9c6f1 Kernel: Don't use multiboot2 explicitly. Parse it to common structure 
This allows support of multiple different bootloaders
 2023-11-17 18:54:59 +02:00
Bananymous 447da99f0b Kernel/LibC: Implement readlink and readlinkat 2023-11-11 23:16:52 +02:00
Bananymous 2191ca46bb Kernel: Make TmpFS enforce max page count. 2023-11-07 16:13:21 +02:00
Bananymous cec04a2858 Kernel: Remove now obsolete RamFS 
Everything is using now the better TmpFS which uses physical pages
for page allocation instead of the static kmalloc memory.

Bananymous c20f773c5d Kernel: /tmp is now TmpFS instead of RamFS 2023-11-07 02:36:22 +02:00
Bananymous a46b2f43d9 Kernel: Make ProcFS use the new TmpFS internally 2023-11-07 02:35:44 +02:00
Bananymous a20f8607de Kernel: Implement TmpFS Inode unlinking and deletion 2023-11-06 21:49:12 +02:00

Bananymous 639fd8804c Kernel: Implement TmpFS directory listing 2023-11-06 21:05:58 +02:00
Bananymous cbb2c37e00 Kernel: Implement TmpFS inode chmod 2023-11-06 20:11:34 +02:00
Bananymous ab4f033385 Kernel: Cleanup TmpFS code and block access doesn't require allocs 
TmpFS blocks are now accessed with a simple wrapper
 2023-11-06 20:07:09 +02:00
Bananymous 1ed08f62d3 Kernel: TmpInode blocks are on demand allocated 2023-11-06 10:44:37 +02:00
Bananymous 8164c15b6c Kernel: Implement read/write/truncate for TmpFileInode 2023-11-05 02:28:43 +02:00
Bananymous f9bf47ab30 Kernel: Start work on proper TmpFS in Heap instead of kmalloc memory 2023-11-04 18:18:45 +02:00
Bananymous e5ffadb109 Kernel: Add better APIs for fast page 2023-11-04 18:13:16 +02:00
Bananymous 6d899aa6ce BuildSystem: using sysroot doesn't need root privileges anymore! 
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.
 2023-11-04 17:50:43 +02:00
Bananymous 120f7329b1 BAN: Update ASSERT api 
its now much harder to mix < with <= and > with >=
