13 hours	kern/amd64: proc: Don't dequeue procs in idle loop	Ian Moffett
	There is no need to dequeue any processes in the idle loop as this happens once per timer interrupt Signed-off-by: Ian Moffett <ian@osmora.org>
13 hours	kern/amd64: proc: md_proc_yield -> md_proc_idle	Ian Moffett
	Improve naming to be less confusing Signed-off-by: Ian Moffett <ian@osmora.org>
15 hours	kern/amd64: Introduce kernel threads	Ian Moffett
	Introduces kernel threads. by using the proc_ktd() function, one can spawn a CPL 0 running thread to the desired code. Signed-off-by: Ian Moffett <ian@osmora.org>
3 days	kern: proc: Implement process sleeping and waking	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
3 days	kern/amd64: Try to continue if no proc on switch	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
3 days	kern/amd64: Set RBP when kicking processes	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
5 days	kern: proc: Remove redundant flag set	Ian 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 days	kern/amd64: proc: Mark process as exiting on kill	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
6 days	kern: proc: Add initial penv block support	Ian 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 days	kern/amd64: Attempt to dequeue on a cores first go	Ian 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>
2025-09-23	kern/amd64: proc: Deallocate mapped frames on exit	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19	kern/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>
2025-09-17	kern/amd64: proc: Add proc_kill() routine	Ian 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>
2025-09-17	kern/amd64: proc: Add initial context switch logic	Ian Moffett
	This commit introduces new functions that will be useful for having multiple processes run on the system. - Add md_proc_yield() - Add md_proc_kick() - Add md_sched_switch() Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-16	kern/amd64: proc: Do not kick proc in md_set_ip()	Ian Moffett
	Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-16	kern: proc: Add initialization code for ring 3	Ian 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>
2025-09-16	kern: proc: Add initial proc init + PCB code	Ian 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>
