Hi Masami,

Have you compiled OP-TEE with the CFG_VIRTUALIZATION set ?

https://urldefense.com/v3/__https://optee.readthedocs.io/en/latest/architect... [optee[.]readthedocs[.]io]

I have also been trying to bring OPTEE up on the QEMU aarch64 environment with xen but not much success as yet.

Long time ago I used QEMU to develop virtualization support. So it is one of the supported platforms. Can you share what issues you encountered?

I still haven't reached the part where I enable OP-TEE. My issues are with the initial XEN setup on QEMU with TF-A images in path. I have a working setup with uboot->Xen->Dom0 linux on QEMU.

Next I tried adding BL components in the flow. Linux boots up but crashes. BL1 -> Bl2 -> Bl31 -> uboot -> xen -> Dom0 Not sure but this may be due to the additional parameters I pass in QEMU (-machine virt,secure=on). Crash log which I see * 1.757127] megasas: 07.714.04.00-rc1*

On the u-boot prompt , I manually modify the fdt passed to xen.

Any pointers on what could be possibly going wrong will be very helpful.

Hi Alex,

Have you enabled the OP-TEE support on Xen on your matchartbin?

When I ran Xen Dom0 with OP-TEE, I got below error.

[ 6.482047] optee: probing for conduit method. (XEN) d0v18 Unhandled SMC/HVC: 0xbf00ff01 [ 6.482301] nvme nvme0: 1/0/0 default/read/poll queues [ 6.490154] optee: api uid mismatch [ 6.498962] optee: probe of firmware:optee failed with error -22

Would you know this issue?
