Hi Amir,

I am still unable to get the QCOMTEE driver to work on db845c. As I can see machine: "qcom,sdm845" is not supported for tzmem based on SHM brigde here: drivers/firmware/qcom/qcom_tzmem.c +81. I am still seeing following logs from userspace:

# /mnt/unittest -d [test_print_diagnostics_info][31] test_get_client_env_object. [test_supplicant_release][65] test_supplicant_worker killed.

I think you should first check here for SHM bridge support. If available then only add a QTEE platform device.

On platforms not supporting SHM Bridge, the module should fall back to non-SHM mode. Isn't it the case?
