sources/
  Recursive hypervisor library code.
sources/drivers/vmm_rec/
  Static recursive hypervisor library.
sources/drivers/vmm_rec_env/
  Implementation of a remote attestation prover using Abyme library.
sources/drivers/82579LM/
  Bare metal UEFI Intel e1000e network controller driver.
sources/drivers/eric/
  ERIC PCIe peripheral UEFI driver.
  ERIC can be used as : a DMA attack platform as well as a remote attestation
      verifier.

Submodules

abyme-challenge/
  There is the implementation of challenges sent from ERIC prover to Abyme
  verifier in a remote attestation scheme.

edk2/
  Submodule for QEMU/OVMF firmware needed if using QEMU

  dependencies : acpica; nasm

  $ git submodule update --init
  $ make -C BaseTools
  $ . ./edksetup.sh BaseTools
  $ cat Conf/target.txt
  $ OvmfPkg/build.sh \
    -a IA32 -a X64 \
    -D SECURE_BOOT_ENABLE \
    -D TPM2_ENABLE -D TPM2_CONFIG_ENABLE \
    -D FD_SIZE_2MB -D EXCLUDE_SHELL_FROM_FD

  For SMM debugging go and see :

gnu-efi/
  Submodule for GNU efi toolchain to build efi applications

  $ make

uefi-gdb/
  Submodule for efi applications and drivers debugging with gdb

Working directories to create if needed (rules associated in make targets)

img-arch/
  Archlinux cdrom and distro disk to be used with QEMU target

  $ wget https://<archrepo>/archlinux-yyyy.mm.dd-x86_64.iso -O arch.iso
  $ qemu-img create -f qcow2 vdisk.qcow2 10G

  And install eventually archlinux on vdisk.qcow2
  Note that you can work using the live disk only
