|
|
Name decided & creation of os-k.eu
|
|
|
|
2018-12-06 @os-k-team <os-k-team@os-k.eu>
|
|
Actually started project, began MBR, decided directories organization, created
|
|
this file and others
|
|
|
|
2018-12-08 @os-k-team <os-k-team@os-k.eu>
|
|
* MBR : actually supports Long Mode Compatibility Verification
|
|
* A20 line Enabling : added
|
|
|
|
2018-12-21 @os-k-team <os-k-team@os-k.eu>
|
|
Boot in two stages
|
|
* First stage : 512B MBR code that loads second stage loader from FAT16
|
|
* Second stage : enables A20, switches into lm and write colored text =D
|
|

2019-03-17 @os-k-team <os-k-team@os-k.eu>
|
|
Migration to GRUB
|
|
* Kernel : boots, prepared by the loader. Both are loaded by GRUB
|
|
* Multiboot : chose to use v1 because the v2 lacks on documentation
|
|
* Architecture Support : x86_64 ONLY
|
|
|
|

|
Memory and terminal
|
|
* Memory map and basic malloc function : functionnal
|
|
* Buffer library : implemented for terminal
|
|
* Stack : 8MB long and isn't anymore in conflict with the kernel space
|
|
* sprintf functions : created
|
|
|
|
2019-04-09 @os-k-team <os-k-team@os-k.eu>
|
|
* Terminal : now buffered (static)
|
|
* Whole Project Tree : big reorganization
|
|
* Makefile : suffered a lot, so we improved it
|
|
* (KeStartPanic) : doesn't need to lock the terminal
|
|
* Basic heap and memory allocator : created
|
|
|
|

|
Interrupts and I/O
|
|
* IDT, ISR exception handler : created
|
|
* RTC time based ticks : created but buggy
|
|
* Keyboard IRQ handling (TODO buffer BStdIn) : functionnal
|
|
|
|
2019-04-27 @os-k-team <os-k-team@os-k.eu>
|
|
IDT Overhaul
|
|
* IDT : can now register new IRQ handlers at runtime
|
|
* Exception handler : crashdumps with registers
|
|
* RTC time based ticks : functionnal
|
|
|
|
2019-05-06 @os-k-team <os-k-team@os-k.eu>
