7 hoursdocs: Add syscall updates to readme progressIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
7 hourskern/amd64: syscall: Use current platform latchIan Moffett
Use the current platform latch when selecting a syscall window from the current domain. Signed-off-by: Ian Moffett <ian@osmora.org>
9 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.

12 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>

Add a testing program for ELF loading purposes. This is to be removed in later versions of Lunos Signed-off-by: Ian Moffett <ian@osmora.org>
27 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>
27 hourskernel/amd64: mp: Use NULL instead of wrappingIan Moffett
It is best to return NULL when there is no next CPU instead of wrapping so we have an indicator at where the list ends. Signed-off-by: Ian Moffett <ian@osmora.org>
