Hi,
Notice the test_spmc.sh script looks broken on master (notifications vm to sp test fails). We'll investigate and hopefully provide a fix shortly.

Hi,
I am trying to build BSP part of Total Compute platform from the following link:
https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs…
But I am facing some issues in Board Support Package Build section, after running following command:
bitbake tc0-artifacts-image
I am getting the following Error during one of the executing tasks of above command:
ERROR: secure-partitions-1.0+gitAUTOINC+2fc7e10c7c-r0 do_fetch: Fetcher failure for URL: 'http://gee.cs.oswego.edu/pub/misc/malloc.c;name=dlmalloc'.
Unable to fetch URL from any source.
Can I please get some help with this error?
Regards,
Rahul
Looking at the trusted firmware documentation it says that “Only Arm’s FVP platform is supported to use with the TF-A reference software stack.” Have you gotten this to work on a physical device, or do I need to add support for my own board?
Thanks,
Friedrich
Hi Rahul,
Notice Hafnium as an hypervisor (in the normal world) is no longer a 'supported' configuration. It's still mainly maintained as legacy and for test purposes.
The project focuses on the SPM (aka Hafnium in the secure world).
Adding an hypervisor is a bit beyond the scope of the project.
The best reference for you is perhaps to reproduce the Total Compute platform:
https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs…
If you build the BSP part (no Android),
you get this setup: linux (NS EL1/0), no hypervisor, TF-A at EL3, Hafnium at SEL2, OP-TEE at SEL1.
You can run the optee xtest suite from linux console which reaches OP-TEE as a secure partition through Hafnium.
Regards,
Olivier.

Hi Olivier,
I wanted to try Hafnium with FVP but could not find the clear instructions like the ones available for Hafnium with QEMU.
In Hafnium Documentation, I was able to run tests with FVP with following command:
$ make && kokoro/test.sh --fvp
But I could not find instructions to run Hafnium and primary VM with Linux on FVP separately from Testing purposes, like in case of QEMU.
If Hafnium with QEMU is not going to work in secure world, from where can I find instructions for running Hafnium with VMs (Linux, OPTEE) on FVP in normal and secure world?
Regards,
Rahul

Hi Rahul,
TF-A + SEL2/Hafnium isn't supported on qemu.
All our testing is done on Arm's FVP, or Total Compute platform.
Regards,
Olivier.

Hi Olivier,
Thanks for helping.
Also, I want to run Hafnium with QEMU in secure world.
From where can I get the instructions for that purpose?

Hi,
In your experiment, everything runs in the normal world.
Hafnium at NS EL2.
The primary VM hosting linux at NS EL1.
Regards,
Olivier.

Hi,
I have just started to learn about Hafnium and I am following Getting Started steps of it.
I built DTB with
/dts-v1/;
/ {
hypervisor {
compatible = "hafnium,hafnium";
vm1 {
debug_name = "Linux VM";
kernel_filename = "vmlinuz";
ramdisk_filename = "initrd.img";
};
};
};
And after setting up RAM disk, I was able to boot into Linux VM with following command:
qemu-system-aarch64 -M virt,gic_version=3 -cpu cortex-a57 -nographic -machine virtualization=true -kernel out/reference/qemu_aarch64_clang/hafnium.bin -initrd initrd.img -append "rdinit=/sbin/init"
But I am unable to understand whether Hafnium and Linux are running in Normal World or Secure World or At which Level (EL1, EL2, S-EL1 or S-EL2...) Hafnium and Linux are running.
Can I please get some help in understanding this?
Regards,
Rahul

Hello team,
Currently the amount of memory allocated for GICR frames is determined by the number of supported CPUs. However, the GIC redistributor might have more frames than the number of PEs. In such a case, it is possible that the core index constructed from GICR_TYPER register points to a non-existent PE. For such a case, the GIC discovery and init sequence should move to the next redistributor frame. Today, the code asserts if there are holes in the CPU topology or if GICR_FRAMES > MAX_CPUS.
Downstream Tegra platforms provide more GICR frames than number of CPUs and require the support posted to gerrit [1]. Request the team to review and post feedback.
Thanks.
