CMA-memory-to-offload-FNN-PLUS-module-to-eNPU - #1023
Conversation
…ion for AudioReach Add a dynamic CMA pool for the AudioReach audio stack on qcs6490-rb3gen2. Use alloc-ranges to let the kernel pick a free address rather than a fixed reg, which avoided EFI-reserved memory at 0x9cc00000. Add 4 MiB alignment to satisfy CMA_MIN_ALIGNMENT_BYTES. Wire memory-region into q6apmdai so the q6apm-audio-mem-cma child driver can attach the pool. Based on the equivalent implementation for lemans (SA8295P).

…eNPU audio offload Add the three LPASS AML stream IDs to remoteproc_adsp in the kodiak EL2 overlay so that the q6apm-audio-mem-cma child driver can obtain an IOMMU domain via iommu_get_domain_for_dev(dev). Without these SIDs the CMA device has no IOMMU domain (has_iommu=0) and IOCTL_MAP_HYP_ASSIGN falls through to the SCM path, which fails on RB3Gen2 because Gunyah owns the SMMU. SID assignments: 0x1860 / mask 0x9 — ML Activation + Weights + Write streams 0x1862 / mask 0x1 — ML Config + Bias streams 0x1864 / mask 0x0 — ML Normalized Data stream Link: https://lore.kernel.org/all/20260825133333.376591-1-karthik.s@oss.qualcomm.com/ Signed-off-by: shaspand <shaspand@qti.qualcomm.com>
