Added finding the next free cluster
Added name to long name
Added long name to short name
Added tests for above

Added createLongNameEntry + tests

Moved tests to bottom

Added createShortNameEntry + test

Used the RTC for the date and time for the created short entry

Tidied createEntries


A bit of refactor

No symlinks for FAT32

findNextFreeCluster updates FAT

Reordered tests to better follow the FAT32FS code
FAT32 has no support for symlinks, so removed code around this.
Removed open_args from createNode as it doesn't need it

Added writeEntries + tests

Write the short and long entries to disk
findNextFreeCluster update cluster chain with parent cluster

Added FAT32 write + tests

This Added the ability to create files and directories and write to files.
Added location of the short dir entry for the file so can update the size of the file on disk
Added folders to the test FAT32 directory.
Also fixed minor bug in mkfat32

Added check for destroying the filesystem


Fixed error message for cluster size


Simpler if condition


0x0FFFFFFF => 0xFFFFFFFF


Spelling


Fixed test

Refactored tests for the scheduler and task


Revert "Refactored tests for the scheduler and task"

This reverts commit 2bf56a368bc18f2bd2d33c385e3672d07e4431d9.

Refactored tests for the scheduler and task


Task fmt


Task fmt again >:(


Ramdisk

Added vfs init to initialise the root node
Added the ramdisk.initrd file to grub
Update makeiso to copy the ramdisk to the modules folder
Add a ramdisk step to create a ramdisk to be leaded by grub and parsed by the kernel
Add test files for runtime tests of ramdisk

vfs.init => vfs.setRoot


Improved ramdisk step

Also spelling

Changed name for the initrd

Initial scheduler
Fix TSS

Also change to .{} syntax where appropriate.
Added the SS segment
Fixed spelling

Refactoring GDT


Multitasking working for now


WIP scheduler

Refactored Bitmap a bit

WIP still


Task switching working

Handlers return the stack pointer that will be used to restore the tasks stack, normal handlers will return the same stack pointer it was called with where task switching will return the stack pointer of the next task and restore its state using the interrupt stub.

Initial scheduler done


Created a stage 2 init task


Change u32 to usize


Move Task to arch specific


WIP


WIP2


Removed esp from task, replaced with stack_pointer


Removed the debug logs


Fixed init task stack


Change pickNextTask to pointer manipulation

This allows less allocations so faster switching

Temporary enable interrupts for some runtime tests

PIT and RTC need interrupts enabled to run their runtime tests

Renamed schedule => pickNextTask, comptime bitmap for pids not task init

And some other stuff: No pub for the task anymore
Use the leak detector allocator

Fmt


Fix unit tests

And some other stuff :P

PR review

Moved Task out of arch and have the stack init in the arch file
Mocking clean up
Removed commented code
Renamed createTask to scheduleTask where the user will have to provide a task to schedule
Removed redundant pub in log runtime test
Removed global allocator for scheduler
Cleaner assembly in paging

Fmt


Added new Scheduler test mode


Added new test mode to CI


Removed one of the prints


Added doc comment, task test for i386


Removed test


WIP


Runtime tests work

Have a global set in one task and reacted to in another. Also test that local variables are preserved after a task switch.

Removed new lines


Increased line length


Move the allocation of the bool above the task creation

Remove the old and in with the new
Added the new testing to the OS files

Some spelling
INOUT => IN/OUT
Added some doc comments to log

Added the new runtime to the build + added the None test mode

Moved some stuff around
None test mode is the default to run/build the OS normally with no runtime tests.

Add the new runtime testing to the CI


Updated README and CI


Increased timeout


Print the log message


Spelling


Move runtime to test folder


Add new RT to tty


Add a log to use the unmapped memory to cause page fault in release


Ensure the integer overflow happens even in release builds
