Kernel: Add prefs font for terminal output before file system
2023-02-23 01:22:50 +02:00
a4980acc88
Kernel: Fonts can now be parsed from the filesystem and set to terminal
...
We currently dont have a fallback font if we cannot get to filesystem
initialization, but that will come later. I can't test on real hardware
for this reason.

Kernel: Sleep now actually sleeps and allows idling
2023-02-19 18:52:25 +02:00
460fc3a29f
Kernel: Start working on filesystem
...
We have a basic PATA driver (for reading) and gpt parser.

All: rename every function from UpperCamelCase to snake_case
...
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

Kernel: Implement somewhat functioning multithread support
...
This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D

Kernel: Add option to disable Serial output
...
This makes all debug output to appear on the TTY
2023-01-25 22:51:42 +02:00
c0bc002ac6
Kernel: Move debug printing to its own file
...
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized

1b9f7aa815
Kernel: Rewrite the whole VESA driver
...
We dont support vga text mode currently. I might add it later if needed.
I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
2023-01-23 13:21:53 +02:00

3f7a61a4d2
Kernel: VESA driver has now second buffer for fast scrolling
...
This allows us to not read from video memory, since it was very slow
I also implemented fast path for graphics clearing and scrolling if bpp is 32

Kernel: You can now disable APIC from the grub commandline
2022-12-20 11:57:09 +02:00

Kernel: Replace PIC with APIC
...
If APIC/IOAPIC is not found, we fallback to PIC
Interrupts don't seem to work on real hardware (?)

kprint is now just a #define to Printer::print<terminal_putc>.
This allows us to use same print formatting for serial output :)
