Bananymous 0b5fcb3f88 Kernel/LibC: Add crt* files to LibC and remove crt0 from kernel 
There was no reason for libc get crt0 from kernel.

Bananymous f33c0bad99 Toolchain: Clone GCC and Binutils from git 
This feels much cleaner than just downloading tar balls from
pregiven urls. Also patching works much better like this!

I added --disable-initfini-array since global constructors were
not called.

Bananymous 18f61c5427 Kernel: Fix ACPI DSDT address 
Read x_dsdt address only if fadt's length contains it. Bochs seems
to have version 1 fadt without the x_* fields.

Bananymous 229082a1b2 BAN: Rewrite String with small string optimizations 
String now holds a 15 byte sso buffer. I'm not sure what the size
should actually be but 15 will work for now. Maybe the sso buffer
should be contained in an union with one bit flag in size instead of
variant that uses extra 8 bytes for type index.

This patch buffs sizeof(String) from 24 bytes to 32 bytes on 64 bit.
I assume this is much better version than the old which had to make
allocation even for empty strings :D.

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 d98f84f9d3 BAN: Update ByteSpan API

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 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 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.

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 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.

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

I used to treat all ethernet deivices as E1000 but now it is actually
verified before initialization
