Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work. 2018-10-16 11:01:38 +02:00			`#pragma once`

Implement event loop timers. GObjects can now register a timer with the GEventLoop. This will eventually cause GTimerEvents to be dispatched to the GObject. This needed a few supporting changes in the kernel: - The PIT now ticks 1000 times/sec. - select() now supports an arbitrary timeout. - gettimeofday() now returns something in the tv_usec field. With these changes, the clock window in guitest2 finally ticks on its own. 2019-02-01 03:50:06 +01:00			`#include <AK/Types.h>`
