Not recommended for performance. config FSL_DPA_HAVE_IRQ bool default y config FSL_DPA_CAN_WAIT bool default y config FSL_DPA_CAN_WAIT_SYNC bool default y config FSL_DPA_PIRQ_FAST bool "fast-path processing via IRQ" depends on FSL_DPA_HAVE_IRQ default y ---help--- By default, configure fast-path handling to be triggered by IRQ. Drivers can modify this at run-time, but for linux it makes sense for all handling to be triggered by IRQ, unless a special run-to-completion application is being built. config FSL_DPA_PIRQ_SLOW bool "slow-path processing via IRQ" depends on FSL_DPA_HAVE_IRQ default y ---help--- By default, configure slow-path handling to be triggered by IRQ. Drivers can modify this at run-time, but for linux it makes sense for all handling to be triggered by IRQ, unless a special run-to-completion application is being built. config FSL_DPA_PORTAL_SHARE bool "allow portals to be affine to multiple CPUs" default y ---help--- If the kernel, via its device-tree, will be required to use a single Qman or Bman portal for multiple CPUs, then select this option. Note however that compiling with this option will result in a very slight (but non-zero) overhead even when the feature is not being used. config FSL_DPA_UIO tristate "Export USDPAA portals via UIO" depends on UIO default y ---help--- Portals are exported as UIO devices for use by USDPAA (User Space DataPath Acceleration Architecture) applications. config FSL_BMAN bool "Freescale Buffer Manager support" default y if FSL_BMAN config FSL_BMAN_PORTAL bool "Bman portal support" default y ---help--- Compiles support to detect and support Bman software corenet portals (as provided by the device-tree). config FSL_BMAN_CONFIG bool "Bman device management" default y ---help--- If this linux image is running natively, you need this option. If this linux image is running as a guest OS under the hypervisor, only one guest OS ("the control plane") needs this option. config FSL_BMAN_TEST tristate "Bman self-tests" depends on FSL_BMAN_PORTAL default n ---help--- This option compiles self-test code for Bman. config FSL_BMAN_TEST_HIGH bool "Bman high-level 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_BMAN_TEST_THRESH bool "Bman threshold test" depends on FSL_BMAN_TEST default y ---help--- Multi-threaded (SMP) test of Bman pool depletion. A pool is seeded before multiple threads (one per cpu) create pool objects to track depletion state changes. The pool is then drained to empty by a "drainer" thread, and the other threads that they observe exactly the depletion state changes that are expected. config FSL_BMAN_DEBUGFS tristate "Bman debugfs interface" depends on FSL_BMAN_PORTAL && DEBUG_FS default y ---help--- This option compiles bman debugfs code for Bman. endif # FSL_BMAN config FSL_QMAN bool "Freescale Queue Manager support" default y if FSL_QMAN config FSL_QMAN_PORTAL bool "Qman portal support" default y ---help--- Compiles support to detect and support Qman software corenet portals (as provided by the device-tree). config FSL_QMAN_BUG_AND_FEATURE_REV1 bool "workarounds for errata and missing features in p4080 rev1" depends on FSL_QMAN_PORTAL default y ---help--- If this option is selected, the driver will be compiled with workarounds for errata as well as feature limitations (relative to more recent parts) of p4080 rev1. On unaffected revisions, this support incurs only a negligable overhead, typically only a couple of instructions per non-fast-path operation (the fast-path operations are unaffected). If in doubt, say Y. config FSL_QMAN_POLL_LIMIT int default 32 config FSL_QMAN_PORTAL_DISABLEAUTO_DCA bool "disable discrete-consumption support on cpu-affine portals" default n ---help--- By default, auto-initialised cpu-affine portals support discrete-consumption acknowledgements, but this may be unimplemented in the simulation model. config FSL_QMAN_NULL_FQ_DEMUX bool "support NULL demux handlers" default y ---help--- Normally, incoming frame dequeues and messages from Qman to a software portal provide a direct demux to the owner of the corresponding FQ. However, exotic "zero-conf" possibilities can be supported if other cpus (or operating systems) can schedule "NULL" FQs to a receiver's portal. If this option is selected, the driver will support this feature, but it adds a small overhead to the hottest-path in the driver, so it should be disabled unless needed. config FSL_QMAN_DQRR_PREFETCHING bool "support prefetching or DQRR (if stashing disabled)" default y ---help--- Normally, portals are configured to stash DQRR entries, but if this is not the case, then s/w needs to invalidate and prefetch ring entries. Selecting this option supports both cases and chooses the best one at run-time, but introduces a small overhead in some hot paths of the driver, so disable it if you know stashing will be configured. config FSL_QMAN_CONFIG bool "Qman device management" default y ---help--- If this linux image is running natively, you need this option. If this linux image is running as a guest OS under the hypervisor, only one guest OS ("the control plane") needs this option. config FSL_QMAN_TEST tristate "Qman self-tests" depends on FSL_QMAN_PORTAL default n ---help--- This option compiles self-test code for Qman. config FSL_QMAN_TEST_STASH_POTATO 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. config FSL_QMAN_TEST_HIGH 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_ERRATA bool "Qman errata-handling self-test" depends on FSL_QMAN_TEST default y ---help--- This requires the presence of cpu-affine portals, and performs testing that handling for known hardware-errata is correct. config FSL_QMAN_DEBUGFS tristate "Qman debugfs interface" depends on FSL_QMAN_PORTAL default y ---help--- This option compiles qman debugfs code for Qman. # H/w settings that can be hard-coded for now. config FSL_QMAN_FQD_SZ int "Size of Frame Queue Descriptor region" default 9 ---help--- This is the size of the FQD region defined as: PAGE_SIZE * (2^value) ex: 9 => PAGE_SIZE * (2^9) # Corenet initiator settings.
