Drew Galbraith 242a18ae3c [zion] Finish cleaning up process capability interface. 
Make all functions generic and specify existing/vs new cap.
 2023-06-16 15:09:15 -07:00
Drew Galbraith fc94bc5bf5 [zion] Update process interface to simplify capability insertion. 
Take a templated KernelObject with explicit permissions.
 2023-06-16 15:04:33 -07:00
Drew Galbraith a47bac9966 [zion] Dynamically check Capability type. 
Instead of passing an enum with the capability when creating it, relying
on polymorphism and a template struct tag to determine the object type
at runtime.

This is cleaner and avoids errors where we pass the wrong capability
type with the cap and do a bad cast at runtime.

Drew Galbraith b8b6576b7f Cleanup AHCI Ident a bit and reduce logging 2023-06-12 23:32:24 -07:00
Drew Galbraith 6986f534f8 Add a method for blocking threads on ports. 
Additionally add the first lock class since we are becoming more
concurrent.

Drew Galbraith 0f0e39d1e9 Further parse AHCI information. 
Send an IDENTIFY command to each drive and set up a hook to handle
interrupts.

Drew Galbraith 47e3d11060 Add a syscall for creating a physical memory VMO 2023-06-08 02:36:47 -07:00
Drew Galbraith 56789400d7 Allow mapping the PCI Config so Yellowstone can map it. 
This is a temp system call. Evemtually we should probably supply the
root process with all of the system physical memory objects.
 2023-06-07 22:45:42 -07:00
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 a5c4d40575 Refactor error types and error reporting 2023-06-07 08:51:23 -07:00
Drew Galbraith 81b925eea0 Add a basic IPC setup with Channel Object. 
Pass a process a channel endpoint on startup that it will use to
get it's initial capabilities.

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 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.
