2025-09-20kern: Initialize ACPI before cpu_conf() callIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: syscall: Add initial write(2) stubIan Moffett
Here we add a write(2) stub and add it to the UNIX syscall interface. We also move the UNIX syscall numbers into compat/unix/syscall.h Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: proc: Add address checking routineIan Moffett
Add routine to check if an address is valid within a process's address space. More work will need to be done with this but this introduces a great starting point Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: proc: Move sys_exit() to sys/compat/unix/*Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: proc: Keep track of mapped areas with rangesIan Moffett
This commit adds a virtual memory range queue to the process descriptor in order to keep track of mapped pages and free their respective frames upon program exit. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: vfs: Add namei() prototype functionIan Moffett
Introduce a namei() prototype function to build upon when implementing core namei() logic. The prototype simply implemenets the path parsing and mimicks a UNIX-like (shell) namei output. Signed-off-by: Ian Moffett <ian@osmora.org>

2025-09-17kern/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.

2025-09-15kernel/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>
