I have some manifest code in TF-A side in below link. Maybe I should remove this patch from TF-A? Is there any document that describe the manifest loading and SP image loading process? I only find Hafnium case in this link: https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/compon...

HI Achin,
There is no log from CPU1 when I set log level as 40. The BL31 size limitation prevent me to set log level as 50. Could you help confirm that all manifest file related packing is done in optee-os side for Cortex-A53 case? I mean nothing should checked in TF-A side for invalid manifest case. I see code just check NULL pointer and emit "Invalid or absent SPM Core manifest".
Regards, Jun

Hi Jun,
It seems to me that OP-TEE is not initialising at all since the SPMD in EL3 cannot locate its manifest file.
This should not cause an issue when Linux later attempts to turn on secondary CPUs. Are there any TF-A logs on CPU1 at all?
cheers, Achin ________________________________ From: Jun Nie jun.nie@linaro.org Sent: 22 April 2021 08:26 To: Olivier Deprez Olivier.Deprez@arm.com Cc: tf-a@lists.trustedfirmware.org tf-a@lists.trustedfirmware.org; Achin Gupta Achin.Gupta@arm.com; Gyorgy Szing Gyorgy.Szing@arm.com; Manish Pandey2 Manish.Pandey2@arm.com Subject: Re: How does SPM impact PSCI functions?
Hi Olivier,
BTW: Below log is emitted by the LInux kernel. Does FFA logic in OPTEE impact PSCI function?

Hi Olivier,
Below are git repo, log and build option. But OPTEE log disappear after TF-A enabling SPM. I guess it is due to manifest loading failure and OPTEE is skipped in boot chain. For the OP_TEE, I ported the SPM patches on branch https://git.trustedfirmware.org/OP-TEE/optee_os.git/log/?h=psa-development, except the last one: 1ba62d4 SPMC: Pass device regions to SP. That patch introduce build failure. Thanks for your time!

Hi Jun,
Can you provide the TF-A and OP-TEE git trees/branches you use? TF-A SPMD upstream expects usage of FFA_SECONDARY_EP_REGISTER FF-A v1.1 ABI that your OP-TEE version might not be using.
Also please share logs from TF-A and OP-TEE boot.
Thanks, Olivier.

Hi,
I just find that secondary CA53 CPUs boot fail with error -95(as below definition and log) in the kernel after enabling SPM with option: SPD=spmd SPMD_SPM_AT_SEL2=0. How does SPM impact PSCI functions? Or which code lines should I check to debug this?
#define EOPNOTSUPP 95 /* Operation not supported on transport endpoint */
