Earlier commits from March 2017 - Mary 2017 include: * updated README * licensing * fixed kthread arg passing by using stack bottom, not top (LIKE AN IDIOT!). * kthreads with args/retval wrapping are working but i can't figure out how to actually call them once reconstructed from the stack! * threading is working! dunno how to return from a thread yet though, haha. * DOES NOT RUN. context seitching still in progress * DOES NOT BUILD. still working on context switching code * added initial context switching framework. DOES NOT WORK yet * Added rust log functionality, closes #1 * large reorganization of source * fix keyboard issues, basic kbd is working now. fixed stupid error in keycodes_ascii crate * keyboard works now with unsafe VecDeque as a queue, but there's no real issue with it using unsafe static mut * DOES NOT BUILD. In-progress commit. In the kbd interrupt handler, we cannot use Mutex (will cause deadlock), which means we can't use lazy_static. Tried to use Once<>, but it's not working with RefCells that would allow mutability. Need to find an alternate solution. * keyboard still causing deadlock somewhere. might be the fact that the KBD_QUEUE mutex is being locked by both the kbd interrupt handler and by the rust_main * keyboard works on the interrupt side, but my main loop that reads from the KBD_QUEUE in our main function causes the system to lockup... * keyboard driver compiles but untested at runtime * keyboard library compiles, but may not work yet. Still need to remove other dependencies on std library, like the queue crate * added initial keyboard indirection layer and keyboard scancode to ascii library, which will be its own separate crate. * fixed interrupt table indexing issue * interrupts work but keyboard handler isn't finished yet, so it can only be triggered once * added basic serial I/O support for debugging to QEMU console

Rust's log crate supports no_std, we should utilize it and use
set_raw_logger()to write to serial port.The text was updated successfully, but these errors were encountered:
