Ok thanks.

odeprez added a comment to T925: ATF v2.5-rc0 fails to build rk3399 support with gcc11.

Is this building natively on arm64 host?

Can you please provide the link to the gcc11 toolchain you use?
AFAIK latest public Arm release of the cross compiler toolchains is 10.2 (https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads)

Raghu as you are originator for this ask; can you state more about the requirements as to the why we'd really need to do so?

odeprez added a comment to T897: Implement retrieving of memory region by specifying address ranges.

In particular this is about specifying the offset field in the endpoint memory access descriptor.

odeprez added a comment to T896: Implement FFA_RXTX_UNMAP_32 interface.

The possible envisioned scenario is related to booting TF-A+UEFI and support for authenticated variables.

odeprez added a comment to T723: Support Arm SMMU.

SMMUv3.2 supports secure Stage-2 translations and that's the feature we intend to enable as a first step.
The IP also supports "nested translations" aka S-EL1 SMMU paravirtualization although we're not looking at this option immediately.

odeprez added a comment to T723: Support Arm SMMU.

We're considering the SMMUv3.2 support which covers the Secure Stage-2 mappings (https://developer.arm.com/documentation/ihi0070/latest).
This is still in initial investigation phases, but we hope to share design details and early patches by end of Q4'20.

Nerver mind :) Glad if it works now. Cheers, Olivier.

The log seems to show additional options versus the regular TF-A build:
-march=armv8-a -O2 -pipe -fstack-protector-strong -fno-plt

Unfortunately the option won't show on asm files, but only on C files.

I tried on an arm64 machine (using gcc8.3) but did not reproduce the issue.

I suspect this problem arises because of building natively (although I agree this should normally work).

odeprez added a comment to T632: End-of-interrupt (EOI) handling is missing for RAS interrupts.

I'm not too much versed into RAS error handling, so please take my explanation below with care.
I suggest you send the question to the TF-A ML to get more sensible insights.
