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
2022-04-14kernel: port init's `printf` implementationdzwdz
2022-04-14kernel: basic page allocator, `process_free`dzwdz
2022-04-11kernel: implement `cpu_pause()` in assembly, remove `irq_interrupt_flag()`dzwdz
2022-04-11kernel/arch: only allow IRQs in the idle processdzwdz
2022-04-10kernel/driver: modify the ps2/serial drivers to use ring_tdzwdz
2022-04-10kernel/i386: rewrite the serial driver to wait for IRQdzwdz
proper multiprocess support!
2022-04-10kernel: idle processdzwdz
2022-04-09kernel/vfs: prevent the vfs functions from switching processesdzwdz
2022-04-07kernel: remove the `/tty` devicedzwdz
2022-04-07kernel: add a /com1 devicedzwdz
2022-04-05kernel/ps2: don't discard entire buffer on partial readsdzwdz
2022-03-30kernel: remove the keyboard driver, add a `/ps2` devicedzwdz
2022-03-27kernel/vfs: partial ATA drive supportdzwdz
2022-03-27style: remove the semicolons after cases in ISRdzwdz
2022-03-27kernel/tty: poll only on IRQs, don't burn cyclesdzwdz
2022-03-27kernel/i386: implement the ps/2 keymap as an arraydzwdz
2022-03-26kernel: IRQs; PS/2 keyboard supportdzwdz
2021-11-14shared: use a single implementation of mem* functions everywheredzwdz
2021-10-15slightly clean up all the assembly codedzwdz
2021-10-15kernel: quit QEMU once there are no running processes leftdzwdz
2021-10-08ATA: implement the IDENTIFY PACKET DEVICE commanddzwdz
2021-10-08remove return statements from void functiondzwdz
2021-10-08ata: proper drive type detection; soft reset; 400ns delay functiondzwdz
2021-10-07ATA: detect device typedzwdz
2021-10-07ATA: read identify data, detect drive sizedzwdz
2021-10-07kernel/i386: fix port_in16's return value sizedzwdz
2021-10-07kernel/i386: add 16bit port io functionsdzwdz
2021-10-07kernel/i386: rename the port io functions with their bit lengthdzwdz
2021-10-06kernel/i386: implement part of ATA IDENTIFYdzwdz
2021-10-05isr: simplify the exception handlerdzwdz
2021-10-05kill the process that caused an exception instead of panickingdzwdz
2021-10-02implement serial/tty inputdzwdz
2021-10-02serial: implement a selftestdzwdz
2021-10-02rename kernel/arch/log.h to io.hdzwdz
it's not related to logging but to general io, the old name didn't make sense
2021-09-21start using sparse's `-Wnon-pointer-null`dzwdz
While I personally don't see a reason to use NULL instead of 0, I assume that whoever made that a sparse default knew what they were doing.
2021-09-21start using sparse's `-Wdecl`dzwdz
2021-09-20create a few specialized panic()sdzwdz
thanks to this i can tell which ones are placeholders, and which ones should stay
2021-09-19call sysenter_setup before kmain_earlydzwdz
makes the code slightly simpler, imo
2021-09-18merge `kernel/types.h` and `init/types.h`dzwdz
2021-09-14merge the `syscall_handler` and `_syscall` declarationsdzwdz
i think that making the call a bit more "transparent" makes the code nicer
2021-09-14add support for 4-parameter syscallsdzwdz
2021-09-12log cr2 on page faultsdzwdz
2021-09-12make the inline functions staticdzwdz
otherwise this doesn't compile with -O0
2021-09-11replace `user_ptr` with a linux-style `__user` annotationdzwdz
2021-09-11fix the `sparse` warningsdzwdz
2021-09-05move most of the memory stuff to kernel/mem/dzwdz
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
2021-08-22kernel: implement assertdzwdz
