ARM CCA Emulation

Note, this is the old version which was started by Huawei. The new version, which was started by the Linaro and ARM community is at https://github.com/Huawei/Huawei_CCA_RMM/wiki/ARM-CCA-emulation-on-QEMU-(New-Community-Version) We host them in the same repos under different branch.

This documentation describes how to run ARM CCA test cases in QEMU emulation environment.

Disclaimer: This is not an actual product of Huawei. Use it for research purpose only. Do NOT use it for production.

Prepare the environment

The current directory contains three subdirectories:

qemu (https://github.com/Huawei/Huawei_CCA_QEMU.git branch cca-v6.2)
tf-a-tests (https://github.com/Huawei/Huawei_CCA_TFTF.git branch qemu-v6.2)
trusted-firmware-a (https://github.com/Huawei/Huawei_CCA_TFA.git branch qemu-v6.2)

Prepare the compiler: export PATH=/path/to/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf/bin:$PATH

Compile

mkdir qemu/build
cd qemu/build
../configure --target-list=aarch64-softmmu --disable-docs --enable-debug
make
cd ../..

make -C tf-a-tests CROSS_COMPILE=aarch64-none-elf- PLAT=qemu DEBUG=1 USE_NVM=0 SHELL_COLOR=1 TESTS=realm-payload tftfr
make -C trusted-firmware-a CROSS_COMPILE=aarch64-none-elf- ARCH=aarch64 PLAT=qemu ARM_DISABLE_TRUSTED_WDOG=1 ENABLE_RME=1 DEBUG=1 BL33=../tf-a-tests/build/qemu/debug/tftfr.bin all fip

rm -f flash.bin
dd if=trusted-firmware-a/build/qemu/debug/bl1.bin of=flash.bin bs=4096 conv=notrunc
dd if=trusted-firmware-a/build/qemu/debug/fip.bin of=flash.bin seek=64 bs=4096 conv=notrunc

Run Test Cases

./qemu/build/qemu-system-aarch64 -nographic -serial telnet::54341,server -smp sockets=2,cores=4 -machine virt,secure=on,virtualization=on,gic-version=3 -m 2048 -cpu max -d unimp,guest_errors,rme -D qemu.log -bios flash.bin

In another console, run telnet localhost 54341. You should get the following output:

$ telnet localhost 54341
Trying ::1...
Connected to localhost.
