anna	60ec99692c	serial: "fix" buffer truncation bug ... DMA just uses one buffer rather than two now lmao	3 years ago
anna	d4411fd6b6	mutex: add wait queue and spinlocks	3 years ago
anna	7e6dbad05f	sched: complete rework of context switching ... The old strategy was to only do context switching from within the PendSV handler. This worked fine until now because all syscalls were handled either atomically or just returned -EAGAIN if the resource was locked or busy. However, with the introduction of I/O wait, we need to be able to sleep directly from within the kernel by moving the context switching completely into the kernel.	3 years ago
anna	60f1ebea8a	arch: use CMSIS after all ... It was inevitable, tbh. I really wanted to do everything entirely from scratch, but all those hardware registers are just too much to be maintained by a single person. And since i plan on supporting different boards at some point in the future, it would be complete madness to redo everything for that board.	3 years ago

anna	adce3f3ed7	arch/at91sam3x8e: update struct reg_sw_snapshot ... With my discovery of how to actually use thumb2 instructions in assembly files, the layout of register snapshot has changed because they are now pushed in consecutive order.	3 years ago
