Hi,
Another out of curiosity question about: VERBOSE: SMMUv3: Memory allocated at 0000008800043000 for CMDQ
Hafnium as SPMC in the secure side must allocate data structures only from secure memory. Do you confirm this memory range is marked secure by the TZASC controller?
Regards, Olivier.

Hi,
1/ About: VERBOSE: SMMUv3 Total StreamTable entries: 16777216
I wonder if this is a realistic value suggesting SMMU_S_IDR1.S_SIDSIZE=24? In which case the stream table size would grow up to 1GB. Can you confirm this parameter value on your platform?
Also can you confirm the smmu base address on your platform, as it may be that hafnium probes the smmu io space from a wrong address?
2/ can you tell which commit hash you're using for hafnium?
We've observed random stack overflows corrupting data sections (in this case the smmu static data) because of stack size limitation. Can you confirm you have this change in your tree: https://git.trustedfirmware.org/hafnium/hafnium.git/commit/?id=64b421e19a061...
Thanks, Olivier.

Hi, when I enabled SMMU by set the config file as follows： aarch64_toolchains("secure_aem_v8a_fvp") { cpu = "cortex-a57" origin_address = "0x06000000" boot_flow = "//src/boot_flow:spmc" console = "//src/arch/aarch64/pl011" iommu = "//src/arch/aarch64/arm_smmuv3" gic_version = 3 gicd_base_address = "0x2e000000" gicr_base_address = "0x2e140000" gicr_frames = 8 heap_pages = 100000 max_cpus = 8 max_vms = 16 # branch_protection = "standard" toolchain_args = { plat_ffa = "//src/arch/aarch64/plat/ffa:spmc" plat_psci = "//src/arch/aarch64/plat/psci:spmc" plat_interrupts = "//src/arch/aarch64/plat/interrupts:gicv3" plat_prng = "//src/arch/aarch64/plat/prng:prng" secure_world = "1" pl011_base_address = "0x2A400000" smmu_base_address = "0x3FC00000" smmu_memory_size = "0x400000" # enable_mte = "1" plat_log_level = "LOG_LEVEL_VERBOSE" } }
I encountered a problem，The log is as follows， there is not enough memory for init SMMU， I have define “heap_pages to 100000”， but it's still not enough，Do you have any suggestions?
