5 dayskern/amd64: bus: Use higher half VA for MMIOIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskern: proc: Remove redundant flag setIan Moffett
The PROC_EXITING flag is already set within the MI layer of the process management core Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskern/amd64: proc: Mark process as exiting on killIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskern: proc: Add initial penv block supportIan Moffett
This commit introduces the initial support for the process environment block and implements argv and argc. Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskern/amd64: Attempt to dequeue on a cores first goIan Moffett
When a CPU core first starts up, it has no proceses to assign to itself. This commit ensures that the processor will right away start trying to find tasks to grab from its runqueue. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-27kern/amd64: panic: Halt all processors on panicIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-23kern/amd64: proc: Deallocate mapped frames on exitIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: bus: Simply return bus_space, don't remapIan Moffett
As of now, the bootloader handles setting up the MMIO regions and we'll need huge page support (2 megs) for reassigning MMIO space Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: pci: Add bus framework and PCI BAR mapperIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern/amd64: proc: Add proc_self()Ian Moffett
Introduce a new proc_self() function to get the current running process on the current CPU core. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-17kern/amd64: proc: Add proc_kill() routineIan Moffett
Add a new function to kill processes and clean them up. They will then be marked as EXITING and it is up to the parent to do the rest. Signed-off-by: Ian Moffett <ian@osmora.org>

2025-09-16kern: proc: Add initialization code for ring 3Ian Moffett
This commit introduces several new functions for switching the processor into a ring three context along with its task's respective process descriptors to be implemented correctly. - Add md_set_ip() to update proc instruction pointer - Add stack definitions - Add stack mapping logic ... Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-16kern: proc: Add initial proc init + PCB codeIan Moffett
This commit introduces the initial logic for putting process descriptors in an initialized state. This commit also introduces the process control block definition. Signed-off-by: Ian Moffett <ian@osmora.org>
