Drew Galbraith f26fd73116 [Zion][Denali] Move to MSI for AHCI devices. 
This will allow us to properly do interrupts for XHCI devices in the
future.

Also move PCI device header parsing to a shared library.

Get rid of the old irq register format which supplied an irq number and
instead pass the appropriate irq number back out to the caller.

Drew Galbraith d7c1022b7f [Zion] Print RBP on GP Fault. 2023-12-08 14:30:24 -08:00
Drew Galbraith 8adde27d9b [Zion] Add a thread sleep call. 
For now this can only sleep in increments of the scheduler quantum
(currently 50ms). It also uses a somewhat ineffecient way of tracking
the sleeping threads - it will scale linearly with the number of
sleeping threads.

Drew Galbraith 2dd69f5844 [Zion] Map user stacks in as regular MemoryObjects. 
This allows us to easily track the physical memory so it
can be freed when the thread exits. It also simplifies the page fault
handler as it just needs to check regular mappings to find a user stack.
