Bananymous bc1d1bf919 LibC: implement and call __cxa_finalize() on exit() 
This allows global destructors to be actually called

Bananymous f05b9a6877 Kernel/LibC: Add crt* files to LibC and remove crt0 from kernel 
There was no reason for libc get crt0 from kernel.

Bananymous ea5ed3001e 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 f312c3a4d7 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 1af3ca19ab 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 0757834176 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 3bffbe330d BAN: Update ByteSpan API 
Add ByteSpan::as_span<T> and const versions of as() and as_span()
require T to be const.

Bananymous 091c5b6a66 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

is a good start.

Bananymous 1e2c2fb973 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 5bfeb9f3ca 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 db5c24b2a5 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 e2e5c31d54 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 be3efb0b92 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 48980b56ab 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 b767317a7a 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.
