The following items will be graded for this checkpoint.

Programming assignment:

src/pci.c
- pci_init
- Add delegation functions necessary to handle VirtIO devices.
- Make sure you properly handle type 0 and type 1 devices.
Add a file called src/virtio.c and associated src/include/virtio.h
- In this file, set up the descriptor table, driver ring, and device ring for all VirtIO device. Recall VirtIO devices have a unique vendor ID in the PCI ECAM.
- The Makefile will automatically pick up any *.c file in the src directory, so your virtio.c will be seen by the Makefile.
  - You may need to 'make clean' prior to building when you add a new file.
src/main.c
- - Add pci_init() call. This will need to be made after the MMU is turned on and the paging/heap have all be initialized.
Always consider asynchronicity when writing your code! If another HART could possibly map to a page table, it must be locked!

Create a tag called "checkpoint2". I will grade checkpoint2, or if that doesn't exist, the master branch.
