Andreas Kling	1b2ef8582c	Kernel: Make File's can_read/can_write take a const FileDescription& ... Asking a File if we could possibly read or write it will never mutate the asking FileDescription&, so it should be const.	2019-11-04 14:03:14 +01:00
Andreas Kling	b2e502e533	Kernel: Add Thread::block_until(Condition). ... Replace the class-based snooze alarm mechanism with a per-thread callback. This makes it easy to block the current thread on an arbitrary condition: void SomeDevice::wait_for_irq() { m_interrupted = false; current->block_until([this] { return m_interrupted; }); } void SomeDevice::handle_irq() { m_interrupted = true; } Use this in the SB16 driver, and in NetworkTask :^)	2019-07-14 14:54:54 +02:00
Andreas Kling	dcfa93e71f	SB16: Use a snooze alarm to block the current thread while playing.	2019-07-13 20:15:17 +02:00
Robin Burchell	6c4024c04a	Kernel: First cut of a sb16 driver ... Also add an AudioServer that (right now) doesn't do much. It tries to open, parse, and play a wav file. In the future, it can do more. My general thinking here here is that /dev/audio will be "owned" by AudioServer, and we'll do mixing in software before passing buffers off to the kernel to play, but we have to start somewhere.	2019-07-13 08:00:24 +02:00
