Bananymous 0d67e46041 Kernel: Add config read/write api to PCI 2023-09-22 17:20:35 +03:00
Bananymous bc1087f5a7 Kernel: Add pointer validation API to page table 2023-09-22 17:20:35 +03:00
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
 2023-09-22 17:20:28 +03:00
Bananymous 5fae3cec2a Kernel: Implement SYS_SYNC and add sync executable to userspace 
You can (and have to) manually sync disk after writes to it.
 2023-09-11 01:26:27 +03:00
Bananymous b0c22b61ec Kernel: Writes to disk are not synchronous anymore 
Implement "proper" DiskCache syncing

Bananymous aa59142bfa Kernel: Fix ext2 file write 2023-09-11 01:20:39 +03:00
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 720bc418a6 All: Clear lines with only whitspace in them 2023-09-10 00:31:42 +03:00

Bananymous 7e08f0fb66 Kernel: Start work on making inodes more thread safe 
All inode operations are now locked and thread blocked
 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.
 2023-09-08 11:46:53 +03:00
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...
 2023-09-08 02:43:08 +03:00
Bananymous e631eb7a7a Kernel: Fix possible out-of-bounds disk access in ext2 2023-09-08 02:42:53 +03:00
Bananymous 7c11ea3694 Kernel: Cleanup TTY::read() 2023-09-07 15:27:21 +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
 2023-09-07 15:06:27 +03:00
Bananymous 0deab1be51 Kernel: Remove bitmap debug printing from ext2 inode allocation 2023-09-06 01:25:09 +03:00
Bananymous 5a623adaa6 Kernel: Correct inode links count 2023-09-05 14:46:56 +03:00
Bananymous ddd36af0f1 Kernel: Add /dev/tty symlink that targets the current tty 2023-09-05 01:07:52 +03:00
Bananymous 35fd30ee29 Kernel: Implement basic RamSymlinkInode 2023-09-05 01:07:52 +03:00

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.
 2023-09-04 19:34:18 +03:00
Bananymous 9b47603a1d Kernel: Make serial devices to their own class 2023-09-04 14:57:05 +03:00

Bananymous cbd2519b9a Kernel: better handle kernel errors 2023-08-29 00:13:21 +03:00
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.

Bananymous 8c282a5d83 Kernel: O_SEARCH doesn't require any permissions

This allows us to stat e.g. device files for which we don't have
the permissions.
