2023-12-19kernel/amd64: lapic: Fixup LAPIC state trackingIan Moffett
This commit removes the lapic_set_base() function and certain globals from the Local APIC driver so it won't cause problems on hardware with many CPU sockets or that is just wacky. Signed-off-by: Ian Moffett <ian@osmora.org>

2023-12-13kernel/amd64: trap: Add TRAP_NONE defineIan Moffett
This commit introduces the trap type TRAP_NONE to allow for general interrupts as they also use the `trap_frame' but are not interrupts that will occur during instruction execution. Signed-off-by: Ian Moffett <ian@osmora.org>
2023-12-13kernel/amd64: machdep: Cleanup processor_init()Ian Moffett
This commit cleans up processor_init() by tidying up and reordering calls to ensure things will be set up in the correct order. Signed-off-by: Ian Moffett <ian@osmora.org>

This commit fixes some horribly broken TSS code. It is unclear how it got this broken. Signed-off-by: Ian Moffett <ian@osmora.org>
2023-12-13kernel/amd64: trap: Log instruction pointerIan Moffett
This commit adds some logic to trap_handler() which makes it show the instruction pointer from the trapframe. Signed-off-by: Ian Moffett <ian@osmora.org>

2023-12-11kernel: init: Fixup call orderIan Moffett
Some virtual memory routines are called by processor_init()... This is a temporary workaround until these calls are moved to processor_init() Signed-off-by: Ian Moffett <ian@osmora.org>
2023-12-11kernel/amd64: Update arch(9)Ian Moffett
This commit cleans up arch(9) as a few things were noticed. First, it would make sense to identify cores (described by the cpu_info structure) in every arch ported, thus the lapic_id has been changed to id so it can be shared. Some annotations have also been added for the sake of clarity. The manpage for arch(9) has also been cleaned up. Signed-off-by: Ian Moffett <ian@osmora.org>
