Hi, We would like to propose the following topic for discussion at the Tech Forum tomorrow.
* RME Granule Protection Table (GPT) block fusing
The GPT L1 entries needs to be fused to avoid TLB shattering for RME enabled CPUs. We will talk about the different prototype approaches tried in TF-A (EL3 firmware) and issues with each approach. We have a patch in review in which implements the “brute force” fusing algorithm. We explain our reasoning for picking this approach and possible future enhancements which may resolve some of the issues anticipated. Also the fine- grained locking scheme implemented for GPT manipulation will also be discussed.
The patch in review is here : https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/26674. For design details of the GPT Library, please refer here : https://trustedfirmware-a.readthedocs.io/en/latest/components/granule-protec... .
Best Regards Soby Mathew
