* io: add serial output through port 0x3f8 (qemu)Tianhao Wang2024-06-11
| | | | | not yet wrapped with fmt macros because I want some thing stateless. (i.e. I don't want to pass `&mut self` to write_str...).
* chore: remove unused depsTianhao Wang2024-06-11

* mm: fix Range type and addr roundingTianhao Wang2024-06-11
| | | | Signed-off-by: Tianhao Wang <shrik3@mailbox.org>
* mm: add stack based PMATianhao Wang2024-06-11
| | | | | | | use 8MiB reserved array to manage up to 4GiB of physical memory (4K Pages only) Signed-off-by: Tianhao Wang <shrik3@mailbox.org>

* multiboot: get memory info from MB infoTianhao Wang2024-06-11
| | | | Signed-off-by: Tianhao Wang <shrik3@mailbox.org>
* multiboot: basic support for multiboot infoTianhao Wang2024-06-11
| | | | | | | | well, it's not trivial to use bios function because thanks to grub + multiboot, we are already in protected mode when the startup code takes control. Also the MB info is easier to play with than BIOS (or ACPI) Signed-off-by: Tianhao Wang <shrik3@mailbox.org>
* keyboard: pad key translation tableTianhao Wang2024-06-11
| | | | | | | | some keys such as the Win key has larger scancode, causing out-of-bound read in the translation table. As a temp fix pad the tables with 0 up to 100 chars. Signed-off-by: Tianhao Wang <shrik3@mailbox.org>

* PS/2 Keyboard controller: baselineTianhao Wang2024-06-11
|
* add IOPort structTianhao Wang2024-06-11
| | | | So that device IO can be be synchronized.
* keyctl: use bitflags for key modifiersTianhao Wang2024-06-11
| | | | Merge key modifier getters and setters
* make device_io a arch independent interface.Tianhao Wang2024-06-11
| | | | | In arm we will be using MMIO instead of the IO instructions. However the peripherals should use the same interface for IOs.
* basic interrupt/PIC supportTianhao Wang2024-06-11
|
* add println! and panic! macroTianhao Wang2024-02-01
| | | | | The rust lazy_static requires interior mutability. I have to include a Mutex impl (spin::Mutex). But I'd like to implement my own primitives.
