2022-08-04syscalls: add _syscall_sleep()dzwdz
2022-08-03kernel: reuse a single allocation for all vfs_requests of a processdzwdz
$ iostress 32 512 0 > /vtty # before 512 calls, 0 bytes. avg 121133 $ iostress 32 512 0 > /vtty # after 512 calls, 0 bytes. avg 103540 103540/121133 = ~85% I think the tiny bit of added complexity is worth it here.
2022-07-26shared: move some headers from shared/ to camellia/dzwdz
2022-07-18syscalls: implement execbufdzwdz
i have been planning to implement something like this for a while now. it should be faster when doing consecutive syscalls (to be tested). it will also be helpful in writing the elf loader
2022-07-09kernel/pipes: process queueingdzwdz
2022-07-08kernel/proc: remove the type argument from process_handle_getdzwdz
2022-07-05kernel: initial partial pipe supportdzwdz
2022-05-06kernel/proc: reorganize the functionsdzwdz
2022-05-06kernel/proc: get rid of the PS_DEADER state, free processes asapdzwdz
2022-05-05kernel/proc: remove WAITS4IRQdzwdz
2022-05-05kernel: ps2 driver is now a separate backenddzwdz
2022-05-05kernel/proc: remove deathbeddingdzwdz
2022-05-02syscalls: fork() noreap flagdzwdz
2022-05-02shared: fix some stuff i broke + compiler warningsdzwdz
2022-05-02kernel/vfs: always separately allocate the request objectdzwdz
2022-05-01kernel/proc: `process_handle_get` for safely accepting handle idsdzwdz
2022-05-01kernel/proc: make handles separate refcounted objectsdzwdz
2022-04-28kernel/proc: reparent deathbedded processesdzwdz
dead processes now can't have alive children
2022-04-21kernel: consolidate `process_seed` and `run_init`dzwdz
2022-04-21kernel/proc: only expose `process_switch_any()`dzwdz
other parts of the kernel don't need to care about which process exactly gets switched into
2022-04-21kernel/proc: only kill deathbedded processes on switch attemptdzwdz
this makes `process_transition` safe again, as it won't be able to free processes. it was a pretty unintuitive behaviour
2022-04-21kernel: recursive kill()dzwdz
2022-04-21kernel: `shutdown()`; temporarily print process states on shutdowndzwdz
2022-04-16kernel/vfs: store the queue in `vfs_request` itselfdzwdz
2022-04-14kernel/proc: only change state through `process_transition`dzwdz
2022-04-14kernel: store a pointer to the callback function in .waits4irqdzwdz
removes `proc.c`'s pointless dependency on `vfs/root.h`
2022-04-14kernel: basic page allocator, `process_free`dzwdz
2022-04-12kernel/proc: implement `process_next` for simple process iterationdzwdz
2022-04-12kernel: make all sizes unsigned, sort out the sign messdzwdz
2022-04-10kernel: idle processdzwdz
2022-04-10kernel: process_find_multipledzwdz
2022-04-07kernel/vfs: implement a vfs request queuedzwdz
2021-11-02fork2 refactor: every process now has (only) a single controlled vfs_backenddzwdz
2021-10-04implement process_kill()dzwdz
2021-10-04remove support for processes returning strings on exitdzwdz
This isn't really all that useful, it doesn't enable anything that wasn't possible before. With it removed I'll be able to implement process_exit() in a much simpler way.
2021-09-21refactor `await_finish` into `process_try2collect`dzwdz
the new name is terrible, but at least the function now has a clear purpose
2021-09-20use a single struct for all fs_wait return valuesdzwdz
2021-09-18remove `struct process.stack_top` - it was unuseddzwdz
2021-09-15fs_wait: pass the file ID toodzwdz
2021-09-12implement part of `fs_respond`dzwdz
2021-09-12implement most of fs_waitdzwdz
awaited_req is a garbage name but i couldn't come up with a better one. i also have no idea how to handle all the failure states
2021-09-12vfs request refactor pt1dzwdz
2021-09-11replace `user_ptr` with a linux-style `__user` annotationdzwdz
2021-09-08save the vfs_op_request in the process structdzwdz
2021-09-08process struct: replace the generic saved_addr with an uniondzwdz
2021-09-08scaffolding for user fs dispatchdzwdz
2021-09-04refactor finding empty handles to a functiondzwdz
2021-09-04rename file descriptors to handlesdzwdz
2021-08-24switch to using user_ptr for pointers coming from userlanddzwdz
this avoid accidental dereferences, and now it's easy to tell apart which pointers are safe to directly read and which aren't. cons: - const is completely discarded
2021-08-24replace () with (void) in function definitionsdzwdz
`()` means that any amt of arguments will be accepted, which isn't what i want
