Hi all,
I am not sure whether it is OK to ask the question here, but I still
wish you can help me address the problem.
I used to test Hafnium with FVP, and the Linux kernel is provided by
arm-reference-platform. Recently I want to test something on an OPTEE
kernel (rather than a cactus OS). But, since the provided linux kernel
is a bit old (v5.3), its /drivers/tee/optee will not send FF-A calls.
I find that Linux introduces FF-A ABI to OP-TEE driver since v5.16,
which is a relatively new kernel. Previously I download the Linux
kernel here ( https://git.linaro.org/landing-teams/working/arm/kernel-release.git),
but they only provide old kernels. I also try to replace the "linux"
directory with the upstream Linux v5.17 source code, and use the guide
here (https://community.arm.com/oss-platforms/w/docs/459/modify-linux-kernel-conf…)
to compile. But the source seems to be inconsistent with the
arm-reference-platforms.
Can someone help me?
Sincerely,
WANG Chenxu
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?

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
