Kernel: Cleanup TTY::read()
2023-09-07 15:27:21 +03:00
b30af0edca
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

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
323de3c866
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.

Kernel: Make serial devices to their own class
2023-09-04 14:57:05 +03:00

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

BuildSystem: use -a with rsync
...
This allows cmake to not rebuild whole project every time
2023-08-28 11:38:17 +03:00
80e7a89f67
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.

38e72019c7
Kernel: kill() with negative pid actually matches pgid
2023-08-22 14:54:15 +03:00

Kernel/LibC: add dup() syscall and function
2023-08-17 12:03:29 +03:00
871c792976
Kernel: O_SEARCH doesn't require any permissions
...
Except read permissions for all directories in the path
This allows us to stat e.g. device files for which we don't have
the permissions.

2023-08-10 22:01:30 +03:00
b0c8a9cdc4
Kernel: Fix slave PIC
...
we dont mask interrupt 2 in PIC since it corresponds to the
slave PIC. Also cleanup PIC code :)
2023-08-10 21:52:31 +03:00

Kernel: HPET doesn't use the legacy mapping anymore
2023-08-10 21:08:32 +03:00

Kernel: APIC now uses MMIO namespace functions for mmio
2023-08-10 21:07:23 +03:00
0b8396b1a6
Kernel: IDT now sends EOI for every interrupt
...
EOI is sent before calling the interrupt handler. This should be fine
since all interrupts are processed with interrupts disabled
2023-08-09 09:57:02 +03:00
55ef793a74
Kernel: Validate HPET tick period
2023-08-09 09:50:38 +03:00

2023-08-09 08:57:50 +03:00
6fcb191ca0
Kernel: Add PageTable::Flags::CacheDisable
...
Also fix multiple places where we were using uint8_t as page table
flags instead of PageTable::flags_t which we promoted to uint16_t
while back.

2023-08-04 16:06:47 +03:00
c732297623
Kernel: Rename TimerHandler to SystemTimer
...
I changed SystemTimer to only handle the "best" supported timer
it can initialize.
2023-08-04 16:06:47 +03:00
ca5a097ef5
Kernel: Add function to retrieve boot time as timespec
2023-08-04 16:06:47 +03:00
1f8a5f0ce5
Kernel: F11 now prints current time to debug output
...
This allows better timer percision and system freeze checks
2023-08-04 15:22:51 +03:00

IO ports
2023-08-04 15:12:29 +03:00

Kernel: Move RTC to Timer directory

PIT ms counter seems to be off by multiple seconds/minute. I will
be probably changing to HPET for system time
