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.
