Hi all,
I want to boot one or more OPTEE on SEL1, with using Hafnium (v2.4) on
SEL2 and TF-A (v2.4) on EL3, and Arm FVP. Before I can boot multiple
Cactus SP, but I can find little infos about booting OP-TEE.
Can you provide some useful guide?
Sincerely,
WANG Chenxu
Hi,
Note we now have two jenkins jobs started on patch submission:
The regular Hafnium builder running unit tests, hypervisor test suite on qemu, static checks and checkpatch.
A new job running the test_spmc.sh script on FVP, corresponding to the Hypervisor+SPMC configuration with a single and multiple partitions.
This has been a long road, thanks to everyone involved from multiple teams.
Both test results are reported to the gerrit code review.
It remains to fix the Verified+1 vote, based on the two above results. Hope to improve it soonish.
Regards,
Olivier.
Hi,
Can someone please help me in understanding how TF-A (EL3) forwards FF-A calls to Hafnium (SEL2)?
And what Hafnium code I should look into for seeing how Hafnium handles these calls?
Regards,
Rahul

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?
Regards,
Rahul

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
