📄 Description

To see characters echoed in the UEFI shell, launch with USB keyboard on XHCI (and logging still works):

export QEMU_KEYLOG_PATH="$PWD/keystrokes.log"
./build/qemu-system-aarch64-unsigned
-M virt -cpu cortex-a72 -m 512M
-display cocoa
-device virtio-gpu-pci
-device qemu-xhci
-device usb-kbd
-device usb-mouse
-monitor none
-serial null
-drive if=pflash,format=raw,readonly=on,file=build/pc-bios/edk2-aarch64-code.fd
-drive if=pflash,format=raw,file=build/pc-bios/edk2-arm-vars.fd

Build steps used on macOS M1:

  • Install deps: brew install pkg-config meson ninja glib pixman libslirp dtc sdl2 gnutls.
  • From repo root: rm -rf build && mkdir build.
  • Configure for aarch64 with Cocoa/slirp (DTC include/lib set for Homebrew):

cd build
CFLAGS='-I/opt/homebrew/opt/dtc/include'
LDFLAGS='-L/opt/homebrew/opt/dtc/lib'
PKG_CONFIG_PATH=/opt/homebrew/lib/pkgconfig:/opt/homebrew/share/pkgconfig
../configure --target-list=aarch64-softmmu --enable-cocoa --enable-slirp --disable-werror

  • Build: ninja (or ninja -C build from repo root).
  • Binary to run: build/qemu-system-aarch64-unsigned.
