General informations

The Linux kernel configuration item CONFIG_FSL_DPAA has multiple definitions:

QorIQ DPAA1 framework support found in drivers/soc/fsl/qbman/Kconfig

The configuration item CONFIG_FSL_DPAA:

• prompt: QorIQ DPAA1 framework support
• type: bool
• depends on: (( CONFIG_FSL_SOC_BOOKE || CONFIG_ARCH_LAYERSCAPE ) && CONFIG_ARCH_DMA_ADDR_T_64BIT )
• defined in drivers/soc/fsl/qbman/Kconfig

The Freescale Data Path Acceleration Architecture (DPAA) is a set of hardware components on specific QorIQ multicore processors. This architecture provides the infrastructure to support simplified sharing of networking interfaces and accelerators by multiple CPUs. The major h/w blocks composing DPAA are BMan and QMan.

The Buffer Manager (BMan) is a hardware buffer pool management block that allows software and accelerators on the datapath to acquire and release buffers in order to build frames.

The Queue Manager (QMan) is a hardware queue management block that allows software and accelerators on the datapath to enqueue and dequeue frames in order to communicate.

Freescale DPAA 1.x support found in drivers/soc/fsl/qbman/Kconfig

The configuration item CONFIG_FSL_DPAA:

• prompt: Freescale DPAA 1.x support
• type: bool
• depends on: ( CONFIG_FSL_SOC_BOOKE || CONFIG_ARCH_LAYERSCAPE )
• defined in drivers/soc/fsl/qbman/Kconfig
• found in Linux kernels: 4.9–4.18
