Hi Manish,
That's another question I wanted to follow up with. Is there any real benefit of MTE for BL31 given that it doesn't allocate memory dynamically. I guess stack tagging is the only use of MTE in BL31?
The concern in the original email is whether the support is incomplete. Can you confirm?
Thanks, Okash

Hi Okash,
Could you please let us know the real use case/requirement where you want MTE to be available at EL3?
Thanks, Manish Badarkhe

Hi,
I wanted to check the status of MTE support for bl31 itself. It seems like the support was added [1] for clang and armclang but I couldn't find the memory attribute to map pages as tag checked [2]. Is there something I missed?
Thanks, Okash
