kmi/src/uapi/dispatch.c, branch master ACTIVE - Kernel with migrating threads as IPC https://metanimi.dy.fi/cgit/kmi/atom?h=master 2026-01-25T15:14:53Z implement dmem semi-properly 2026-01-25T15:14:53Z Kimplul kimi.h.kuparinen@gmail.com 2026-01-25T15:14:53Z urn:sha1:cd41ed1758f4842d7b78870385e16b579cc89c38 + Add tests and fix virtual mapping, this is enough to start writing proper userspace drivers improve killing processes/threads, test 2024-08-26T15:51:10Z Kimplul kimi.h.kuparinen@gmail.com 2024-08-26T15:51:10Z urn:sha1:b25156373cd89792b1c457b77699bb7f9beb430d + Remove sys_kill() as we should be using a two-stage process where a thread is first orphaned by sys_detach(), and then the thread itself calls sys_exit() after it has done all necessary cleanup in init. add ipc_notify testcase, remove ipc_ghost 2024-08-22T11:57:14Z Kimplul kimi.h.kuparinen@gmail.com 2024-08-22T11:57:14Z urn:sha1:c3ea570bae8f7daeac8e0614a958e983fcf9940e + 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. change sys_ret handling to always include id 2024-08-22T10:19:50Z Kimplul kimi.h.kuparinen@gmail.com 2024-08-22T10:19:50Z urn:sha1:66b39eb7ce9605cbb70defdca7f0eb144855ddcd add malloc test 2024-08-21T20:31:48Z Kimplul kimi.h.kuparinen@gmail.com 2024-08-21T20:31:48Z urn:sha1:97ffab0a8472981b927d0f4e81bb72f6ecd69b86 add ipc_tail() 2024-07-18T14:39:15Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-18T14:39:15Z urn:sha1:f9e23e6e41068d63d42f950941c3d2fc155ef21c + 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 start working on tests 2024-07-09T19:12:27Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-09T19:12:27Z urn:sha1:e8a1df103cc28419dd7d4439c0b1d1739d110f78 + 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. add req_page back in as I realized it's useful 2024-07-07T18:47:14Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-07T18:47:14Z urn:sha1:219c27d420fe0abe5515cefc2513c6fe60aafdf9 + Can be used to pass contiguous memory regions to things like virtio block devices for implementing disk drivers etc. make executable entrypoint universal callback 2024-07-07T15:12:55Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-07T15:12:55Z urn:sha1:fe4c623cb9320226866829317cea8ba0c49e7dbc + 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 pretty massive virtual memory rewrite 2024-07-06T15:14:04Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-06T15:14:04Z urn:sha1:76517486919657ecadda9867125dc6730f29a5b7 + 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.
