Hafnium - Memory attributes precedence checks for mem share

by Joao Alves

Hi Andrew, We have been revising some aspects of the memory sharing implementation. The specification describes a set of precedence rules for the memory attributes specified in the memory transaction descriptor, including: Memory type, cacheability, shareability. The sender would fill the memory attributes for the region to be shared. After memory send, the receiver should retrieve the regions, filling the memory attributes on its transaction descriptor that comply with the referred precedence rules. The referred rules can be found in section 10.10.4 of the newly release FF-A v1.1 beta spec<https://developer.arm.com/documentation/den0077/c/?lang=en>, as follows. Memory type precedence rules ( < reads as is less permissive than): * Device-nGnRnE < Device-nGnRE < Device-nGRE < Device-GRE < Normal Cacheability precedence rules: * Non-cacheable < Write-Back Cacheable Shareability precedence rules: * Non-Shareable < Inner Shareable < Outer shareable These checks are not part of the handling of FFA_MEMORY_RETRIEVE_REQ. Was there an implementation defined reason for this? If so, could you please provide the rationale? Thank you in advance for your help. Best regards, João Alves

Re: [Hafnium] Problems running Hafnium at S-EL2 with TF-A master

by Olivier Deprez

Hi Rebecca, No problem asking. Not immediately related to the TF-A log, but the image specified as BL32 shall rather be the secure Hafnium build (hafnium/out/reference/secure_aem_v8a_fvp_clang/hafnium.bin). The TF-A boot log suggests that the first secure partition is not found within the FIP image. So there is a problem in terms of provisioning the SP into the FIP and have the BL2 loader finding it. It can be a mismatch with UUIDs, or related to the contents of the json layout file. If that's an information you can share, let us know the nature of the secure partition image you wish to have TF-A loaded and booted by Hafnium.

The test command line that fails is: timeout --foreground 300s ./test/hftest/hftest.py --driver=fvp --out out/reference/aem_v8a_fvp_clang --out_initrd out/reference/aem_v8a_fvp_vm_clang --out_partitions out/reference/aem_v8a_fvp_vm_clang --log out/reference/kokoro_log hafnium --initrd test/vmapi/arch/aarch64/aarch64_test Error log is: ERROR: SMMUv3: Linear Stream Table cannot be supported when StreamID bits > 7 ERROR: SMMUv3: Failed to initialize driver Panic: Could not initialize IOMMUs. Has anybody seen this issue? I'll try to debug but thought I'll send an email in case somebody already knows the answer to this. Wondering if I'm missing a knob in the FVP. -Raghu
