Drew Galbraith 09ac87e6f5 [yellowstone] Recieve all caps via init port. 2023-06-17 00:17:43 -07:00
Drew Galbraith 2ea1f90690 [zion] Add a direct port write for the kernel 2023-06-17 00:07:58 -07:00
Drew Galbraith 528723e490 [mammoth] Create a method for getting initial caps. 2023-06-16 23:51:49 -07:00
Drew Galbraith 21b73b5b92 [zion] [yellowstone] Pass the denali VMMO by port as a POC. 
Preparing to bootsrap via port write rather than hard coding capability
ids.

Drew Galbraith 242a18ae3c [zion] Finish cleaning up process capability interface. 
Make all functions generic and specify existing/vs new cap.

Drew Galbraith 30bb10207e Add the Denali disk driver. 
Begin enumerating information from the PCI structure and HBA AHCI
structures.

Currently the PCI structure address is hardcoded but it should be
passed via a capability from the init process in the future.

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 7c9d1075eb Move sys/test to Yellowstone init process. 2023-06-07 11:18:35 -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 b06c76e477 Create a MemoryObject class and use it to load programs. 2023-06-06 21:44:10 -07:00
Drew Galbraith b5ad454ad1 Move Process & Thread to the object folder. 2023-06-06 20:18:53 -07:00
Drew Galbraith 4e278a4664 Make a KernelObject base class for all Capabilities. 2023-06-06 20:13:07 -07:00
Drew Galbraith d358c1d672 Move process be to RefCounted 2023-06-06 19:12:46 -07:00
Drew Galbraith b0c2a6732b Always create threads in CREATED state. 
Simplify the process class to have threads marked as runnable
separately.

Drew Galbraith e2aad55a8a Only dump bootloader modules once. 2023-06-06 15:04:34 -07:00
Drew Galbraith 1db93e5b12 Move PML4 initialization into the VirtualMemory class. 2023-05-30 21:39:19 -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 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 7fe6c24aa5 Add a ProcessManager class to store Process objects. 
Trying out a new method for exposing global objects directly via a
variable.
 2023-05-29 23:35:44 -07:00
Drew Galbraith 7184f527a0 Jump to user mode. 
This instantly creates a page fault as we always map pages with ring 0
permissions.
 2023-05-29 13:06:08 -07:00
Drew Galbraith aefb4f082b Add a kernel ELF module and load it in a new process. 
Don't yet jump to userspace.
