Task fmt


Task fmt again >:(


Ramdisk


Added NotOpened error for file read and write
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


Rename RamdiskFS => InitrdFS


Add deinit for initrd

Add newline parsing
The symbol name can have spaces.
Changed the parseName to use the newline parsing.
Also used str.len

Missed whitespace => newline

Fix the size alignment
The size alignment need to use alignAllocLen and not alignForward as the size align may not be a power of 2.

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

Use the standardTargetOptions for built targets
This will allow the user to build the OS with more fine grain, but there is a white list of supported build targets.
Closes #129

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
