Drew Galbraith 53ff49b265 Add preprocessor directives to supress logs per file. 
Makes the output much cleaner by default but allows for getting more
infor if debugging in the future.

Drew Galbraith add533071b Use APIC for interrupts rather than PIC. 
Still rely on the PIT for now rather than the local APIC timer.

Drew Galbraith 6c10c57bfa Mass rename memory object variables. 
Use shorthand:
AddressSpace -> vmas
MemoryObject -> vmmo

The VM prefix makes these a little more distinguishable in code.

Drew Galbraith a8a4f8d9ab Add checks to mammoth thread lib 2023-06-07 00:25:04 -07:00
Drew Galbraith e246f28d9c Get the second process elf from a MemoryObject instead of hardcoding. 
Allows us to delete the CopyIntoNonResidentProcess function and simply
rely on the MemoryObject copy functions.

Drew Galbraith eb454300e6 Move elf loader into the init loader in the kernel 2023-06-07 00:08:21 -07:00
Drew Galbraith 23895b5c6c Spawn Processes using memory primitives rather than and elf loader. 
This allows us to remove the temporary syscall for that style of process
spawn.

Drew Galbraith 2e1357255c Create a RefCounted type and use it for Thread. 
This should prevent me from actually creating 2 shared ptrs of
a single kernel object with their separate ref counts.

Drew Galbraith f22dd66c8d Manage KernelStacks separately rather than just allocing bytes. 
Create a global KernelStackManager that will handle the relevant allocs.
 2023-05-30 21:28:44 -07:00
Drew Galbraith 3c3341a90f Add a process spawn syscall and use it to start a proc. 
Also add a skeleton VirtualMemory manager to be used per process.
 2023-05-30 20:55:03 -07:00
Drew Galbraith 5bcf1f4e4a Add a second process to be loaded by the bootloader. 2023-05-30 20:54:37 -07:00
Drew Galbraith b9b45c5e45 Add the ability to copy memory to non resident process. 
Use/Test this by loading the user space elf from the kernel process
before it starts rather than as a part of the first thread.

This simplifies thread start a fair bit.
 2023-05-30 01:27:47 -07:00
Drew Galbraith f6609983d2 Move away from using recursive mapping for page tables. 
Having the HHDM-based mapping allows us to more easily map data into
non-resident processes.
 2023-05-30 01:06:01 -07:00
Drew Galbraith c6921b5459 Add validity check in shared ptr 2023-05-30 01:05:50 -07:00

variable.
 2023-05-29 23:35:44 -07:00
Drew Galbraith b58186265e Split Yield and Preempt into separate scheduling functions. 
This switch makes the logic for each much easier to parse.
 2023-05-29 23:09:39 -07:00
Drew Galbraith 3fee5ac9d7 Rework scheduler to store the current thread separately. 
This works better with the sleep thread and lets us check state
transitions more easily.
 2023-05-29 22:54:22 -07:00
Drew Galbraith 656687b183 Schedule on PIC timer raise. 
This causes a page fault because we don't properly handle the sleep
case.
