Re: [Hafnium] .git submodules increase hafnium code size

by Olivier Deprez

Hi Varun, We had similar requests raised internally. 1- First in context of Total Compute delivery from Arm OSS platforms: a. ability to build only the SPMC on TC0 platform (not all reference targets such as qemu, rpi4, fvp) b. use a Yocto provided toolchain. @Arun, your view on how those two items were solved is beneficial to further elaborate our plans. 2- A similar request as 1.b to build Hafnium as part of a distribution on arm64 host: https://developer.trustedfirmware.org/T898 In my view there are two consumers: -A distribution only requiring the Hypervisor/SPMC output binary ("out/reference/.../hafnium.bin") using any toolchain (be it arm64 or x86 host, and arbitrary clang version). -The Hf CI framework/automation needs the above, plus the test framework and tests (dependency on googletest, linux submodules etc). It's important to keep this item alive while trying to solve above item. As you noticed, the Hafnium Hypervisor/SPMC and test environment builds are closely coupled by the use of ninja/gn flow and scripts. They are using a fixed toolchain version through prebuilts to ensure builds are "reproducible", in particular with regards to the Hafnium CI. We intend to approach those problems in the course of Q3 in Arm OSS roadmap. As an early exploration we already have: -clang 12 compiler upgrade. This is necessary if wiling to use any arbitrary clang version: https://review.trustedfirmware.org/q/topic:%22od%252Fhf-clang12%22+(status:… -Ability to build on arm64 host (done, internally). -Identify the flow/script changes such that external dependencies can be used (on-going, internally). I thought of localizing common dependencies to python/shell scripts by the use of definition files included in the mentioned scripts. This is only an early investigation, I will check how this intersects the changes you provided. Regards, Olivier.

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. If you wish to reproduce a known working setup you can use below command lines using master for each tree: TF-a-tests: make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp DEBUG=1 TESTS=spm -j8 Hafnium: make PROJECT=reference TF-A: make CROSS_COMPILE=aarch64-none-elf- SPD=spmd CTX_INCLUDE_EL2_REGS=1 ARM_ARCH_MINOR=5 BRANCH_PROTECTION=1 CTX_INCLUDE_PAUTH_REGS=1 PLAT=fvp DEBUG=1 BL33=../tf-a-tests/build/fvp/debug/tftf.bin BL32=../hafnium/out/reference/secure_aem_v8a_fvp_clang/hafnium.bin SP_LAYOUT_FILE=../tf-a-tests/build/fvp/debug/sp_layout.json all fip Run the model: <path-to-fvp>/FVP_Base_RevC-2xAEMv8A -C pctl.startup=0.0.0.0 -C cluster0.NUM_CORES=4 -C cluster1.NUM_CORES=4 -C bp.secure_memory=1 -C bp.secureflashloader.fname=trusted-firmware-a/build/fvp/debug/bl1.bin -C bp.flashloader0.fname=trusted-firmware-a/build/fvp/debug/fip.bin -C cluster0.has_arm_v8-5=1 -C cluster1.has_arm_v8-5=1 -C cluster0.has_branch_target_exception=1 -C cluster1.has_branch_target_exception=1 -C cluster0.has_pointer_authentication=2 -C cluster1.has_pointer_authentication=2 -C cluster0.restriction_on_speculative_execution=2 -C cluster1.restriction_on_speculative_execution=2 -C pci.pci_smmuv3.mmu.SMMU_AIDR=2 -C pci.pci_smmuv3.mmu.SMMU_IDR0=0x0046123B -C pci.pci_smmuv3.mmu.SMMU_IDR1=0x00600002 -C pci.pci_smmuv3.mmu.SMMU_IDR3=0x1714 -C pci.pci_smmuv3.mmu.SMMU_IDR5=0xFFFF0472 -C pci.pci_smmuv3.mmu.SMMU_S_IDR1=0xA0000002 -C pci.pci_smmuv3.mmu.SMMU_S_IDR2=0 -C pci.pci_smmuv3.mmu.SMMU_S_IDR3=0 It should end up with the following test results: ******************************* Summary ******************************* > Test suite 'FF-A Version' Passed > Test suite 'FF-A RXTX Mapping' Passed > Test suite 'FF-A Direct messaging' Passed > Test suite 'FF-A Power management' Passed > Test suite 'FF-A Memory Sharing' Passed > Test suite 'FF-A features' Passed > Test suite 'SIMD,SVE Registers context' Passed > Test suite 'FF-A Interrupt' Passed > Test suite 'SMMUv3 tests' Passed ================================= Tests Skipped : 0 Tests Passed : 20 Tests Failed : 0 Tests Crashed : 0 Total tests : 20 ================================= NOTICE: Exiting tests.
