Hi Rebecca,

qemu is currently not supported for use with the SPM at S-EL2.

The two available options are FVP (https://trustedfirmware-a.readthedocs.io/en/latest/components/secure-partiti...) or Total Compute platform (https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs/...)

Regards, Olivier.

I'm having problems building TF-A with SPM/S-EL2 support. I can build with PLAT=fvp fine, but building with PLAT=qemu results in the error:

LD /home/rebecca/src/arm-trusted-firmware/build/qemu/release/bl31/bl31.elf /home/rebecca/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-ld: /home/rebecca/src/arm-trusted-firmware/build/qemu/release/bl31/spmd_main.o: in function `spmd_setup': spmd_main.c:(.text.spmd_setup+0x74): undefined reference to `plat_spm_core_manifest_load' spmd_main.c:(.text.spmd_setup+0x74): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `plat_spm_core_manifest_load' make: *** [Makefile:1136: /home/rebecca/src/arm-trusted-firmware/build/qemu/release/bl31/bl31.elf] Error 1

The command line I'm using is:

make PLAT=qemu DEBUG=0 \ CROSS_COMPILE=~/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- \ SPD=spmd CTX_INCLUDE_EL2_REGS=1 BL32=bl32.bin BL33=bl33.bin \ SP_LAYOUT_FILE=sp_layout.json ARM_ARCH_MINOR=4 all fip

Adding the following files to BL31_SOURCES in plat/qemu/platform.mk resolves the problem, but I suspect that's not the correct solution?

plat/common/plat_spmd_manifest.c common/fdt_wrappers.c
