Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	select GENERIC_ALLOCATOR
	help
	  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.

if FSL_DPAA

config FSL_DPAA_CHECKING
	bool "Additional driver checking"
	help
	  Compiles in additional checks, to sanity-check the drivers and
	  any use of the exported API. Not recommended for performance.

config FSL_BMAN_TEST
	tristate "BMan self-tests"
	help
	  Compile the BMan self-test code. These tests will
	  exercise the BMan APIs to confirm functionality
	  of both the software drivers and hardware device.

config FSL_BMAN_TEST_API
	bool "High-level API self-test"
	depends on FSL_BMAN_TEST
	default y
	help
	  This requires the presence of cpu-affine portals, and performs
	  high-level API testing with them (whichever portal(s) are affine
	  to the cpu(s) the test executes on).

config FSL_QMAN_TEST
	tristate "QMan self-tests"
	help
	  Compile self-test code for QMan.

config FSL_QMAN_TEST_API
	bool "QMan high-level self-test"
	depends on FSL_QMAN_TEST
	default y
	help
	  This requires the presence of cpu-affine portals, and performs
	  high-level API testing with them (whichever portal(s) are affine to
	  the cpu(s) the test executes on).

config FSL_QMAN_TEST_STASH
	bool "QMan 'hot potato' data-stashing self-test"
	depends on FSL_QMAN_TEST
	default y
	help
	  This performs a "hot potato" style test enqueuing/dequeuing a frame
	  across a series of FQs scheduled to different portals (and cpus), with
	  DQRR, data and context stashing always on.
