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.
 2023-06-16 15:58:50 -07:00
Drew Galbraith 75b1f2d21c [zion] Store capability ids on the CapabilityTable. 
This is preferable to storing it in the capability itself since the id
is really just an index for the containing process.
 2023-06-16 15:27:09 -07:00

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.
 2023-06-16 14:53:57 -07:00
Drew Galbraith b4902a79ef [zion] Add per-process CapabilityTable object 
Store this information in it's own object to make the API clearer.

Drew Galbraith be12fa9a19 Add mutex fixme 2023-06-16 14:25:23 -07:00
Drew Galbraith 4e328c2f7a Set RSP0 on context switch 
Previously we only set it on thread init which caused interrupts to
stomp on the stack of the most recently started thread, potentially
overwriting their cr3 and other variables and causing a crash.

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.
 2023-06-08 02:36:59 -07:00
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 bd32e85164 Fix race condition in page fault handler. 
We enabled interrupts before getting the value of cr2 in the handler.
If the handler was preempted, cr2 could have been overriden by a page
fault in a separate thread or process.
 2023-06-07 22:24:50 -07:00

Makes the output much cleaner by default but allows for getting more
infor if debugging in the future.
 2023-06-07 13:51:13 -07:00
Drew Galbraith add533071b Use APIC for interrupts rather than PIC.

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.
 2023-06-07 00:30:26 -07:00
Drew Galbraith e246f28d9c Get the second process elf from a MemoryObject instead of hardcoding.

 2023-06-07 00:19:15 -07:00
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.
