14 hourskern/amd64: Implement syscall domains and windowsIan Moffett
A syscall domain in the L5 kernel is a fixed list of "syscall windows", each syscall window represents a specific platform and/or syscall model. A platform latch within each domain determines which window / platform should be visible. Since syscall domains are per-process, these changes are local to their respective processes.

17 hourskern: init: Add copyrightIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
17 hourskern/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>

32 hourskern/amd64: cpu: Add process load balancingIan Moffett
This commit introduces load balancing of processes between cores by using a scalable "CPU arbiter" which decides how to fetch the next core descriptor. Signed-off-by: Ian Moffett <ian@osmora.org>

Use the OSMORA kernel configuration framework to add options for L5Lunos to parse during early startup. Signed-off-by: Ian Moffett <ian@osmora.org>

38 hourskern: elf: Fix frame calcs + style cleanupIan Moffett
Allocate more than one frame that exists and increment by one if zero. We also did some style fix ups, added an #undef and a break. Signed-off-by: Ian Moffett <ian@osmora.org>

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>

3 dayskernel/amd64: Add task state segment logicIan Moffett
This commit implements the task state segment and splits up processor initialization into two seperate stages. The cpu_conf() function is apart of the first stage and sets up things that should be going by the time the kernel is started / early init. The cpu_init() function runs later functions that initialize further platform specific subsystems. Signed-off-by: Ian Moffett <ian@osmora.org>
