This commit includes a lot of small changes and additions needed to finalize the base implementation of VirtIOQueues and VirtDevices: * The device specific driver implementation now has to handle setting up the queues it needs before letting the base device class know it finised initialization * Supplying buffers to VirtQueues is now done via ScatterGatherLists instead of arbitary buffer pointers - this ensures the pointers are physical and allows us to follow the specification in regards to the requirement that individual descriptors must point to physically contiguous buffers. This can be further improved in the future by implementating support for the Indirect-Descriptors feature (as defined by the specification) to reduce descriptor usage for very fragmented buffers. * When supplying buffers to a VirtQueue the driver must supply a (temporarily-)unique token (usually the supplied buffer's virtual address) to ensure the driver can discern which buffer has finished processing by the device in the case in which the device does not offer the F_IN_ORDER feature. * Device drivers now handle queue updates (supplied buffers being returned from the device) by implementing a single pure virtual method instead of setting a seperate callback for each queue * Two new VirtQueue methods were added to allow the device driver to either discard or get used/returned buffers from the device by cleanly removing them off the descriptor chain (This also allows the VirtQueue implementation to reuse those freed descriptors) This also includes the necessary changes to the VirtIOConsole implementation to match these interface changes.

SerenityOS
Graphical Unix-like operating system for x86 computers.
About
SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.
I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.
Sometimes I write about the system on my github.io blog.
I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
