Makefile
- Added the -std=c++17 flag to enable better constexpr support.
- Removed optimizations as the system would crash with them. The BlueScreen would show an empty callstack on crashes with -O2 so I guess the problem is the missing ebp or something like that.
Changes
- Removed the Input.h/Input.cc files
- Made device classes singletons
- Changed the multitasking assembly (use stack instead of thread_state)
- Many changes to the scheduler (strategy is still round robin):
- Merged dispatcher into the scheduler
- Scheduler no longer uses queue but vector
- Scheduler owns threads (no outside references)
- Threads are addressed by tid from the outside
- Threads are deallocated automatically when killed/exited
- Retrieve threads from the scheduler without deallocation
- Scheduler manages blocked threads
Additions
- Some stream manipulators for CGA_Stream (color) and OutStream (fixed width)
- Logging class with support for colored serial port output
- Main menu to start demos
- A very basic system to broadcast keyboard events to threads
- Basic implementation of vector with iterator support
- Basic implementation of unique_ptr
- Basic implementation of fixed size array (just a wrapper for C-style arrays)
Bugs
- Can't exit the PCSPKdemo (bluescreen)
- Random bluescreens that are hard to pinpoint
- Tree Allocator (uses a red black tree to find best-fit blocks) crashes when freelist root is removed
