TODO

For right now, this is just a place to track todos.

For anything that absolutely must be done before sending the initial patchset to the mailing list for feedback the TODO item is tagged with [RFC].

Current RFC target is: enable hypervisor dynamic memory and UART

TODO

• Support Device Tree and fix drivers/passthrough/riscv/iommu.c usage of device tree
• Change riscv/mm.c and friend to use pte_t instead of unsigned long [RFC]
• Discover ranges of memory via device tree parsing instead of hardcoded [RFC]
• Cleanup _setup_initial_pagetables to reduced reproduced variables [RFC]
• Refactor page table entry routines into functions/macros [RFC]
• Debate the naming of link_ and load_ variable names. Are they clear?
• Properly implement guest atomics guest_atomics.h
• Implement EARLY_PRINTK
• Determine a way to not stomp over OpenSBI (causing a PMP fault) when finding an address space for the heaps [RFC]
  • There are some ideas in the works using the FDT to pass OpenSBI's protected space to the hypervisor, further investigation needed...
• Implement a scheme to prevent re-mapping already used pages with map_domain_page() in mm.c, the scheme ARM uses will not work for RISC-V sv39.
• Setup trap vector (currently there is no IRQ handling)
