Hi Vinod, I don't know what's them compile? Does means 'the driver has public driver, so any arch will compile it'? If so, the compile qdma module need enable config options 'CONFIG_FSl_QDMA' and other architecture should be hide the options. The driver supported arm or arm64 arch, If I change Kconfig to solve compile issues, Can I do that? config FSL_QDMA tristate "NXP Layerscape qDMA engine support" + depends on ARM || ARM64 select DMA_ENGINE select DMA_VIRTUAL_CHANNELS select DMA_ENGINE_RAID select ASYNC_TX_ENABLE_CHANNEL_SWITCH help Support the NXP Layerscape qDMA engine with command queue and legacy mode. Channel virtualization is supported through enqueuing of DMA jobs to, or dequeuing DMA jobs from, different work queues. This module can be found on NXP Layerscape SoCs.
