ids.
 2023-06-16 15:58:50 -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.
 2023-06-16 01:31:23 -07:00
Drew Galbraith ffa2d97a64 First iteration of denali server 2023-06-15 16:20:29 -07:00

interrupts.

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

passed via a capability from the init process in the future.

Drew Galbraith 50201fe6df Updated PCIe walk to be recursive and dump the offset of the sata drive 2023-06-08 00:24:50 -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

 2023-06-07 08:24:10 -07:00
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.
