2024-08-22add ipc_notify testcase, remove ipc_ghostKimplul
+ A bit easier to implement just ignoring the ipc_resp() arguments than try to enforce that a notification is exited from by ipc_ghost(), especially in cases where the root process has been killed.
2024-08-22change sys_ret handling to always include idKimplul
2024-08-21add malloc testKimplul
2024-07-18add ipc_tail()Kimplul
+ ipc_kick() does a forward and a tail at the same time The idea with ipc_tail() is to allow 'trusted' calls, so for example a process is not allowed to willy-nilly open a file, as it has to go via init(), making the eid 1. This way the receiver can know that the request has gone through init() and can open up a new connection (file, whatever) after which requests from that pid/tid are allowed without init() intervention
2024-07-09start working on testsKimplul
+ Current setup will likely not last long, just a stopgap until I figure out how I want to build each testcase etc. Probably dir based, but I'll probably add some scripts that generate the build rules for each test case (or binary?). Also, should probably put ouput files in a build directory and keep the source clean, but again, good enough for now. Will have to start implementing more extensive tests, and probably come up with some way to compare textual output etc.
2024-07-07add req_page back in as I realized it's usefulKimplul
+ Can be used to pass contiguous memory regions to things like virtio block devices for implementing disk drivers etc.
2024-07-07make executable entrypoint universal callbackKimplul
+ Effectively means that all executables can be called into, but if an exe doesn't want to deal with anyone else it should just set a flag like `not_really_a_server` or whatever
2024-07-06pretty massive virtual memory rewriteKimplul
+ The system is now a bit simpler and hopefully easier to understand, while also extending the shared memory to be 1:N, where there is one owner who may become a zombie while waiting for the N to die.
2024-07-04generalize orphantsKimplul
+ Allow threads to make themselves become orphants
2024-07-04add zombie and orphan threadsKimplul
+ Should write this down somewhere but the idea is that when a process gets killed, it frees all the memory it can, making all threads within that process orphans. Orphaned threads are assigned to the init process, which will generally call exit() on each one. Zombie threads are threads that own some bit of shared data, and whose reference count is above zero. They may not be swapped to or called, even though they take up space in thread map and reserve their thread ID.
2024-07-02more complete interrupt handling outlineKimplul
+ Still largely untested, should really try to come up with a proper testsuite, at the moment it's mostly me trying things out in the (as of yet unreleased) kmx repo
2024-07-01expand notifications into interrupt handlersKimplul
+ Terminology is still a bit poor, and will still have to write documentation + implement ipis properly
2024-06-01add sleep syscallKimplul
+ Sets the current core to sleep
2024-05-24rename common to srcKimplul
+ I keep starting to type src and wondering why autocomplete won't work, I guess src is just uncounciously a better name
