Bananymous 2d34b2b8a3 BuildSystem: Add bos short hand for building with zsh completions :) 2023-10-28 22:23:29 +03:00
Bananymous 76f48f095c Kernel: Rewrite a lot of ext2 code 
This commit consists of multiple big changes

1. blocks for inodes are now allocated on demand
  - reading from non allocated block will just return zeroes
  - writing to non allocated block allocates it

2. code doesn't really use raw pointers anymore
  - all casts to uint32_t or structures are now replaced with
    spans. either as<T> or as_span<T> which both are bounds
	checked

3. code doesn't depend on random macros for accessing indirect blocks
  - i added some recursive functions which take care of this :)

Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem

Bananymous 3566ddab00 BAN: ByteSpan can be sliced without specified size

Bananymous 07f8c972b3 Shell: Set get old termios earlier 
I sourced the config file before getting old termios. Sourcing
updated the termios so old_termios was always in non canonical, non
echoing mode.

Bananymous c71ac588b2 BuildSystem: Fix bugs in new build system 
I had not tested the new build system with clean toolchain build
but it seems to work now.

Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.
 2023-10-24 11:56:00 +03:00
Bananymous 71cad2fc38 BAN: Implement ByteSpan 
This is a span over exisiting containers/data types. I'm not too
happy with the constructors and assignment operators, but they will
work for now

Bananymous 61c7a68f4a BAN: add helper to cast Span<T> to Span<const T> 2023-10-20 04:59:08 +03:00
Bananymous c17cdb39d5 Kernel: Map multiboot2 memory in PageTable initialization 
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.
 2023-10-17 01:15:08 +03:00
Bananymous 69a39b7077 Kernel: Start using multiboot2 instead of multiboot 
This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.

Bananymous 0c88c74b76 Kernel: ATABuses are but to compatibility mode if possible 
I don't support native mode ata bus (irq sharing) so ata buses are
but to compatibility mode if possible.
 2023-10-16 16:56:12 +03:00
Bananymous c4a640bcb6 Kernel: Fix ATADevice naming 
ATADevice now stores its name instead of using static buffer. Old
static buffer was changing on every name query. I just hadn't noticed
since virtual machine disks were always sda.

Bananymous 0fdf8b6f68 Kernel: Fix PCI bugs 
IO BarRegion used vaddr instead of the correct paddr. Add API for

verified before initialization

executing function to be in clean environment
