Marcin Undak	3cc5752a69	Kernel: Refactor Aarch64 MailBox class ... The goal was to reduce common setup of messages. Changes: * MailBox turned into singleton to follow existing patterns * Removed device specific messages from MailBox requiring clients to know the details instead * Created base Message class which clients should deriver from It really simplify the usage for more complicated message queues like framebuffer setup - see followup commits.	2021-10-31 12:35:53 +01:00
Nico Weber	bc213ad7a2	Kernel: Add a Timer class for aarch64 ... For now, this can only query microseconds since boot. Use this to print a timestamp every second. This busy-loops until a second has passed. This might be a good first use of interrupts soon. qemu used to not implement this timer at some point, but it seems to work fine even in qemu now (qemu v 5.2.0).	2021-10-02 21:23:28 +01:00
