Drew Galbraith 1cebe547c0 [zion] Allow the sleep thread to be preempted. 
We can't yield it when the next thread is unblocked for now because it
may still be holding a lock that the prempted thread is waiting on.

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 15:09:15 -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.
 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 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.
 2023-06-16 01:52:59 -07:00
Drew Galbraith e5da93757a Working AHCI DMA IPC from yellowstone to denali. 
We have a weird bug in context switching where a process's rsp0 ends up
pointing at the wrong value sometimes which crashes the OS.
