Liav A e606ff3751 Kernel/VirtIO: Determine VirtIO device class also with the PCI device ID 
According to the VirtIO 1.0 specification:
"Non-transitional devices SHOULD have a PCI Device ID in the range
0x1040 to 0x107f. Non-transitional devices SHOULD have a PCI Revision ID
of 1 or higher. Non-transitional devices SHOULD have a PCI Subsystem
Device ID of 0x40 or higher."

It also says that:
"Transitional devices MUST have a PCI Revision ID of 0. Transitional
devices MUST have the PCI Subsystem Device ID matching the Virtio
Device ID, as indicated in section 5. Transitional devices MUST have the
Transitional PCI Device ID in the range 0x1000 to 0x103f."

So, for legacy devices, we know that revision ID in the PCI header won't
be 1, so we probe for PCI_SUBSYSTEM_ID value.
Instead of using the subsystem device ID, we can probe the DEVICE_ID
value directly in case it's not a legacy device.
This should cover all possibilities for identifying VirtIO devices, both
per the specification of 0.9.5, and future revisions from 1.0 onwards.

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.

How do I read the documentation?

Man pages are available online at man.serenityos.org. These pages are generated from the Markdown source files in Base/usr/share/man and updated automatically.

When running SerenityOS you can use man for the terminal interface, or help for the GUI.

How do I build and run this?
