Hi Yann,

I had a quick look into failed cases, both of the failed test cases build with TF-A build option PSCI_EXTENDED_STATE_ID=1.
The failure is because of psci_is_last_cpu_to_idle_at_pwrlvl() returning PSCI_E_DENIED (called by psci_validate_state_coordination()  function)
I have created an action item to analyse it further.

Thanks
Manish

Subject: [TF-A] PSCI patches fail TF-A-tests on 2 platform configs
 
Hi,

Patrick has sent 2 correction patches for PSCI stack in OSI mode there:
https://review.trustedfirmware.org/q/topic:%22fix_psci_osi%22

But when running CI+2, there are 2 platforms for which 2 PSCI OSI tests
are failing:
fvp-ext-pstate-ea-el3|fvp-default|fvp-tftf-fip.tftf-cortexa57x4a53x4-debug
fvp-ext-pstate-ea-el3|fvp-default|fvp-tftf-fip.tftf-aemv8a-debug

I'm not familiar with those test configs, but when checking lava logs,
I see those traces for failing tests:

The "Resumed from suspend state" message interleaved with "Going into
suspend state" seem strange, but I cannot say what could be wrong there.

Maybe there is something wrong with the TF-A patches?
Or the platforms tests or configs need to be updated?
If you have any clue that would be very helpful!


Thanks,
Yann
