6 dayskernel: Introduce per-arch M_WORD_SIZEIan Moffett
The machine word size describes how many bytes of data can be processed at once. Add a per-arch M_WORD_SIZE constant to represent this platform specific characteristic. This commit also adds an MALIGN() helper macro to sys/param.h which can be used for optimization purposes in cases where you want data to be perfectly aligned on a machine word boundary.

8 dayskernel: vsr: Add 'td' argument for most funcsIan Moffett
Allow specification of which process should be targeted for specific operations. Signed-off-by: Ian Moffett <ian@osmora.org>
9 dayskernel: Introduce initial VSR implIan Moffett
This commit introduces the initial implementation of Virtual System Resources (VSRs). Virtual system resources enable specific subsystems to control global state while the VSR acts as a middle man between the process, and the actual resource itself. This allows the products of certain operations to be routed to either the global state or a local (per-process) "shallow copy" whose data and side effects are only visible through that process. An example of something this would be useful for is some sort of transparent access control mechanism where if a process should not modify global system-wide state, it can at least modify the state for itself.

Introduce reporting of the number of halted cores for the scheduler accounting logic. Signed-off-by: Ian Moffett <ian@osmora.org>
10 dayskernel/amd64: Keep track of which cores are onlineIan Moffett
Give each core a bit that indicates whether the core is online or halted. We also provide a cpu_halt() which marks the core as offline. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
14 dayskernel: subr: Check uaddr against mmap ledgerIan Moffett
When validating memory addresses coming from userspace, we currently only check if it is within range of the program stack or data. However, data may also be allocated in the heap which involves addresses stored in the memory map ledger. In order for user programs to be able to pass references to that kind of memory to syscalls, we must be able to check the addresses against ledger entries as well.

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-17kernel/amd64: mp: Pin one idle thread to each coreIan Moffett
Each core on the CPU gets one idle thread so that it is always up to something. To ensure these threads are not bouncing wildly between cores and are always ready for their respective processor to take when they have no threads to grab. We must call proc_pin() on each for every processor. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-17kernel: sched: Add support for CPU pinningIan Moffett
This commit introduces support for pinning processes to specific cores which can be useful for things like, keeping core-specific workthreads running on their respective processors as well as mitigating very specific cases of false-sharing and performance degradation caused by a thread jumping between cores which requires cache-line entries to be thrashed around between them. Threads pinned to a specific core will always see their cached data in the same L1, L2, etc. Signed-off-by: Ian Moffett <ian@osmora.org>

Deprecate SPAWN_WAIT in favor of waitpid() Signed-off-by: Ian Moffett <ian@osmora.org>

2025-07-17kernel/amd64: Set up seperate syscall stackIan Moffett
It is a good idea to have a completely different stack during syscalls. This commit implements a TSS IST entry for syscalls. Signed-off-by: Ian Moffett <ian@osmora.org>

2025-07-16kernel: Sort out switch MI/MD switch logicIan Moffett
Certain operations dealing with context switches are better off being implemented as machine dependent routines which allows us to be flexible with what we can do, as well as the extra benefit of requiring less workarounds to keep things MI. Signed-off-by: Ian Moffett <ian@osmora.org>
