Bananymous c9e09b840e Kernel: Add LAI as a dependency 
I did not feel like implementing AML interpreter now, and wanted
everything AML has to offer. I will be writing my own AML interperter
at some point.

Bananymous 7774f56ab6 Kernel: PCI devices can now create region for BAR 
This creates either MEM or IO region for read/write access to PCI
device.

Bananymous 14a608effd 1000th COMMIT: Kernel: Add basic E1000 driver 
This driver is only capable to read mac address and enable and read
link status

Bananymous 5fae3cec2a Kernel: Implement SYS_SYNC and add sync executable to userspace 
You can (and have to) manually sync disk after writes to it.

Bananymous 202c38a65a Kernel: Improve open() POSIX compatability 
Also rename Process::sys_creat -> create_file since it is not
actually a syscall and only used by open as a healper.

 2023-09-10 00:31:42 +03:00
Bananymous 9e4a87021c Kernel: Fix directory permissions 
We did not care about X bit in directories and instead used only the
R bit for search/read.

Bananymous 5887f6bcaa Kernel: Ext2 directories can allocate new blocks if needed 2023-09-08 10:29:26 +03:00
Bananymous 5d67559e33 Kernel: Fix bug in disk writing 
I have used two weeks in locating a bug in my ext2 implementation
while the bug was actually in disk write. If you called write_sectors
on disk it would write the first sector_size bytes repeatedly to all
asked sectors and this corrupted the disk...

Bananymous e631eb7a7a Kernel: Fix possible out-of-bounds disk access in ext2 2023-09-08 02:42:53 +03:00

Bananymous c1fd341698 Kernel: TTY now reads input byte by byte 
This allows correct behaviour for character streams / keyboard
handling. Serial input can now send working ^C :D

Bananymous 33c81f00b7 Kernel: Receive interrupts for COM1 and COM2 input 
The input has to still be attached to terminal
 2023-09-04 22:07:40 +03:00
Bananymous 55714b90cd Kernel: Rework whole Terminal structure 
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

Bananymous e8a73f9696 BuildSystem: use -a with rsync 
This allows cmake to not rebuild whole project every time
 2023-08-28 11:38:17 +03:00
Bananymous b05cf9ef09 BuildSystem: Base sysroot is now distributed as a tar ball 
This allows file and directory permissions work as intended.

cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

the permissions.
