This script will download and build a minimal AArch64 Linux, BusyBox, QEMU and Valgrind. You will need roughly 10 GB of disk space.

Intended usage: Cache access analysis for AArch64 binaries.

On Ubuntu 18.04.1, just run:

./build.sh

You will probably need to update the toolchain paths:

• CROSS_COMPILE_ELF
• CROSS_COMPILE_LINUX

There may be some dependency checks missing. If you find one, please create a PR or write an issue.

The build.sh script will print the proposed command at the end.

The folder exchange will be shared between the host FS and the QEMU guest (/mnt).

The script is supposed to exit if any of the commands fail and builds all four targets in the order listed below (Versions).

• Linux 5.6.16: Minimal build for AArch64. The shared folder is using Plan 9 folder sharing over Virtio.
• Busybox 1.31.1: Standard build for AArch64
• QEMU 5.0.0: Build for AArch64 with support for virtio and kvm
• Valgrind 3.16.0: Standard build for AArch64. Note the numerous "Implementation tidying-up/TODO notes" in README.aarch64.

valgrind --tool=cachegrind ./my_program

Documentation on Cachegrind can be found here:

• https://valgrind.org/docs/manual/cg-manual.html

The cache layout can be set using:

• --I1=<size>,<associativity>,<line size>
• --D1=<size>,<associativity>,<line size>
• --LL=<size>,<associativity>,<line size>
