*************************************************************************
-ccree specific items
-a.k.a stuff fixing for this driver to move out of staging
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+1. ???
-1. Move to using Crypto Engine to handle backlog queueing.
-2. Remove synchronous algorithm support leftovers.
-3. Separate platform specific code for FIPS and power management into separate platform modules.
-4. Drop legacy kernel support code.
-5. Move most (all?) #ifdef CONFIG into inline functions.
-6. Remove all unused definitions.
-7. Re-factor to accomediate newer/older HW revisions besides the 712.
-8. Handle the many checkpatch errors.
-9. Implement ahash import/export correctly.
-10. Go through a proper review of DT bindings and sysfs ABI
-11. Sort out FIPS mode: bake tests into testmgr, sort out behaviour on error,
- figure if 3DES weak key check is needed
-
-Kernel infrastructure items
-a.k.a stuff we either neither need to fix in the kernel or understand what we're doing wrong
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-1. ahash import/export context has a PAGE_SIZE/8 size limit. We need more.
-2. Crypto Engine seems to be built for HW with hardware queue depth of 1, we have 600++.

-DPAA2 Overview
---------------
-
-DPAA2 is a hardware architecture designed for high-speeed network
-packet processing. DPAA2 consists of sophisticated mechanisms for
-processing Ethernet packets, queue management, buffer management,
-autonomous L2 switching, virtual Ethernet bridging, and accelerator
-(e.g. crypto) sharing.
-
-A DPAA2 hardware component called the Management Complex (or MC) manages the
-DPAA2 hardware resources. The MC provides an object-based abstraction for
-software drivers to use the DPAA2 hardware.
-
-The MC uses DPAA2 hardware resources such as queues, buffer pools, and
-network ports to create functional objects/devices such as network
-interfaces, an L2 switch, or accelerator instances.
-
-The MC provides memory-mapped I/O command interfaces (MC portals)
-which DPAA2 software drivers use to operate on DPAA2 objects:
-
-The diagram below shows an overview of the DPAA2 resource management
-architecture:

- +--------------------------------------+
-
-The MC mediates operations such as create, discover,
-connect, configuration, and destroy. Fast-path operations
-on data, such as packet transmit/receive, are not mediated by
-the MC and are done directly using memory mapped regions in
-DPIO objects.
-
-Overview of DPAA2 Objects
--------------------------
-The section provides a brief overview of some key DPAA2 objects.
-A simple scenario is described illustrating the objects involved
-in creating a network interfaces.
-
--DPRC (Datapath Resource Container)
-
- A DPRC is a container object that holds all the other
- types of DPAA2 objects. In the example diagram below there
- are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
- in the container.
-
- +---------------------------------------------------------+
- | DPRC |
- | |
- | +-------+ +-------+ +-------+ +-------+ +-------+ |
- | | DPMCP | | DPIO | | DPBP | | DPNI | | DPMAC | |
- | +-------+ +-------+ +-------+ +---+---+ +---+---+ |
- | | DPMCP | | DPIO | |
- | +-------+ +-------+ |
- | | DPMCP | |
- | +-------+ |
- | |
- +---------------------------------------------------------+
-
- From the point of view of an OS, a DPRC behaves similar to a plug and
- play bus, like PCI. DPRC commands can be used to enumerate the contents
- of the DPRC, discover the hardware objects present (including mappable
- regions and interrupts).
-
- DPRC.1 (bus)
- |
- +--+--------+-------+-------+-------+
- | | | | |
- DPMCP.1 DPIO.1 DPBP.1 DPNI.1 DPMAC.1
- DPMCP.2 DPIO.2
- DPMCP.3
-
- Hardware objects can be created and destroyed dynamically, providing
- the ability to hot plug/unplug objects in and out of the DPRC.
-
- A DPRC has a mappable MMIO region (an MC portal) that can be used
- to send MC commands. It has an interrupt for status events (like
- hotplug).
-
- All objects in a container share the same hardware "isolation context".
- This means that with respect to an IOMMU the isolation granularity
- is at the DPRC (container) level, not at the individual object
- level.
-
- DPRCs can be defined statically and populated with objects
- via a config file passed to the MC when firmware starts
- it.
-
--DPAA2 Objects for an Ethernet Network Interface
-
- A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX
- queuing mechanisms, configuration mechanisms, buffer management,
- physical ports, and interrupts. DPAA2 uses a more granular approach
- utilizing multiple hardware objects. Each object provides specialized
- functions. Groups of these objects are used by software to provide
- Ethernet network interface functionality. This approach provides
- efficient use of finite hardware resources, flexibility, and
- performance advantages.
-
- The diagram below shows the objects needed for a simple
- network interface configuration on a system with 2 CPUs.

- port/PHY
-
- Below the objects are described. For each object a brief description
- is provided along with a summary of the kinds of operations the object
- supports and a summary of key resources of the object (MMIO regions
- and IRQs).
-
- -DPMAC (Datapath Ethernet MAC): represents an Ethernet MAC, a
- hardware device that connects to an Ethernet PHY and allows
- physical transmission and reception of Ethernet frames.
- -MMIO regions: none
- -IRQs: DPNI link change
- -commands: set link up/down, link config, get stats,
- IRQ config, enable, reset
-
- -DPNI (Datapath Network Interface): contains TX/RX queues,
- network interface configuration, and RX buffer pool configuration
- mechanisms. The TX/RX queues are in memory and are identified by
- queue number.
- -MMIO regions: none
- -IRQs: link state
- -commands: port config, offload config, queue config,
- parse/classify config, IRQ config, enable, reset
-
- -DPIO (Datapath I/O): provides interfaces to enqueue and dequeue
- packets and do hardware buffer pool management operations. The DPAA2
- architecture separates the mechanism to access queues (the DPIO object)
- from the queues themselves. The DPIO provides an MMIO interface to
- enqueue/dequeue packets. To enqueue something a descriptor is written
- to the DPIO MMIO region, which includes the target queue number.
- There will typically be one DPIO assigned to each CPU. This allows all
- CPUs to simultaneously perform enqueue/dequeued operations. DPIOs are
- expected to be shared by different DPAA2 drivers.
- -MMIO regions: queue operations, buffer management
- -IRQs: data availability, congestion notification, buffer
- pool depletion
- -commands: IRQ config, enable, reset
-
- -DPBP (Datapath Buffer Pool): represents a hardware buffer
- pool.
- -MMIO regions: none
- -IRQs: none
- -commands: enable, reset
-
- -DPMCP (Datapath MC Portal): provides an MC command portal.
- Used by drivers to send commands to the MC to manage
- objects.
- -MMIO regions: MC command portal
- -IRQs: command completion
- -commands: IRQ config, enable, reset
-
- Object Connections
- ------------------
- Some objects have explicit relationships that must
- be configured:
-
- -DPNI <--> DPMAC
- -DPNI <--> DPNI
- -DPNI <--> L2-switch-port
- A DPNI must be connected to something such as a DPMAC,
- another DPNI, or L2 switch port. The DPNI connection
- is made via a DPRC command.
-
- +-------+ +-------+
- | DPNI | | DPMAC |
- +---+---+ +---+---+
- | |
- +==========+
-
- -DPNI <--> DPBP
- A network interface requires a 'buffer pool' (DPBP
- object) which provides a list of pointers to memory
- where received Ethernet data is to be copied. The
- Ethernet driver configures the DPBPs associated with
- the network interface.
-
- Interrupts
- ----------
- All interrupts generated by DPAA2 objects are message
- interrupts. At the hardware level message interrupts
- generated by devices will normally have 3 components--
- 1) a non-spoofable 'device-id' expressed on the hardware
- bus, 2) an address, 3) a data value.
-
- In the case of DPAA2 devices/objects, all objects in the
- same container/DPRC share the same 'device-id'.
- For ARM-based SoC this is the same as the stream ID.
-
-
-DPAA2 Linux Driver Overview
----------------------------
-
-This section provides an overview of the Linux kernel drivers for
-DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure"
-drivers and 2) functional object drivers (such as Ethernet).
-
-As described previously, a DPRC is a container that holds the other
-types of DPAA2 objects. It is functionally similar to a plug-and-play
-bus controller.
-
-Each object in the DPRC is a Linux "device" and is bound to a driver.
-The diagram below shows the Linux drivers involved in a networking
-scenario and the objects bound to each driver. A brief description
-of each driver follows.

- ===================================================|========================
-
-A brief description of each driver is provided below.
-
- MC-bus driver
- -------------
- The MC-bus driver is a platform driver and is probed from a
- node in the device tree (compatible "fsl,qoriq-mc") passed in by boot
- firmware. It is responsible for bootstrapping the DPAA2 kernel
- infrastructure.
- Key functions include:
- -registering a new bus type named "fsl-mc" with the kernel,
- and implementing bus call-backs (e.g. match/uevent/dev_groups)
- -implementing APIs for DPAA2 driver registration and for device
- add/remove
- -creates an MSI IRQ domain
- -doing a 'device add' to expose the 'root' DPRC, in turn triggering
- a bind of the root DPRC to the DPRC driver
- The binding for the MC-bus device-tree node can be consulted here:
- Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt
-
- DPRC driver
- -----------
- The DPRC driver is bound to DPRC objects and does runtime management
- of a bus instance. It performs the initial bus scan of the DPRC
- and handles interrupts for container events such as hot plug by
- re-scanning the DPRC.
-
- Allocator
- ----------
- Certain objects such as DPMCP and DPBP are generic and fungible,
- and are intended to be used by other drivers. For example,
- the DPAA2 Ethernet driver needs:
- -DPMCPs to send MC commands, to configure network interfaces
- -DPBPs for network buffer pools
-
- The allocator driver registers for these allocatable object types
- and those objects are bound to the allocator when the bus is probed.
- The allocator maintains a pool of objects that are available for
- allocation by other DPAA2 drivers.
-
- DPIO driver
- -----------
- The DPIO driver is bound to DPIO objects and provides services that allow
- other drivers such as the Ethernet driver to enqueue and dequeue data for
- their respective objects.
- Key services include:
- -data availability notifications
- -hardware queuing operations (enqueue and dequeue of data)
- -hardware buffer pool management
-
- To transmit a packet the Ethernet driver puts data on a queue and
- invokes a DPIO API. For receive, the Ethernet driver registers
- a data availability notification callback. To dequeue a packet
- a DPIO API is used.
-
- There is typically one DPIO object per physical CPU for optimum
- performance, allowing different CPUs to simultaneously enqueue
- and dequeue data.
-
- The DPIO driver operates on behalf of all DPAA2 drivers
- active in the kernel-- Ethernet, crypto, compression,
- etc.
-
- Ethernet
- --------
- The Ethernet driver is bound to a DPNI and implements the kernel
- interfaces needed to connect the DPAA2 network interface to
- the network stack.
-
- Each DPNI corresponds to a Linux network interface.
-
- MAC driver
- ----------
- An Ethernet PHY is an off-chip, board specific component and is managed
- by the appropriate PHY driver via an mdio bus. The MAC driver
- plays a role of being a proxy between the PHY driver and the
- MC. It does this proxy via the MC commands to a DPMAC object.
- If the PHY driver signals a link change, the MAC driver notifies
- the MC via a DPMAC command. If a network interface is brought
- up or down, the MC notifies the DPMAC driver via an interrupt and
- the driver can take appropriate action.

+DPAA2 (Data Path Acceleration Architecture Gen2) Overview
+=========================================================
+
+:Copyright: |copy| 2015 Freescale Semiconductor Inc.
+:Copyright: |copy| 2018 NXP
+
+This document provides an overview of the Freescale DPAA2 architecture
+and how it is integrated into the Linux kernel.
+
+Introduction
+============
+
+DPAA2 is a hardware architecture designed for high-speeed network
+packet processing. DPAA2 consists of sophisticated mechanisms for
+processing Ethernet packets, queue management, buffer management,
+autonomous L2 switching, virtual Ethernet bridging, and accelerator
+(e.g. crypto) sharing.
+
+A DPAA2 hardware component called the Management Complex (or MC) manages the
+DPAA2 hardware resources. The MC provides an object-based abstraction for
+software drivers to use the DPAA2 hardware.
+The MC uses DPAA2 hardware resources such as queues, buffer pools, and
+network ports to create functional objects/devices such as network
+interfaces, an L2 switch, or accelerator instances.
+The MC provides memory-mapped I/O command interfaces (MC portals)
+which DPAA2 software drivers use to operate on DPAA2 objects.
+
+The diagram below shows an overview of the DPAA2 resource management
+architecture::

+ | -network interface -DPNI |
+ | profiles -DPMAC |
+ | -queue portals -DPBP |
+ | -MC portals ... |
+ | ... |
+ | |
+ +--------------------------------------+
+
+
+The MC mediates operations such as create, discover,
+connect, configuration, and destroy. Fast-path operations
+on data, such as packet transmit/receive, are not mediated by
+the MC and are done directly using memory mapped regions in
+DPIO objects.
+
+Overview of DPAA2 Objects
+=========================
+
+The section provides a brief overview of some key DPAA2 objects.
+A simple scenario is described illustrating the objects involved
+in creating a network interfaces.
+
+DPRC (Datapath Resource Container)
+----------------------------------
+
+A DPRC is a container object that holds all the other
+types of DPAA2 objects. In the example diagram below there
+are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
+in the container.
+
+::
+
+ +---------------------------------------------------------+
+ | DPRC |
+ | |
+ | +-------+ +-------+ +-------+ +-------+ +-------+ |
+ | | DPMCP | | DPIO | | DPBP | | DPNI | | DPMAC | |
+ | +-------+ +-------+ +-------+ +---+---+ +---+---+ |
+ | | DPMCP | | DPIO | |
+ | +-------+ +-------+ |
+ | | DPMCP | |
+ | +-------+ |
+ | |
+ +---------------------------------------------------------+
+
+From the point of view of an OS, a DPRC behaves similar to a plug and
+play bus, like PCI. DPRC commands can be used to enumerate the contents
+of the DPRC, discover the hardware objects present (including mappable
+regions and interrupts).
+
+::
+
+ DPRC.1 (bus)
+ |
+ +--+--------+-------+-------+-------+
+ | | | | |
+ DPMCP.1 DPIO.1 DPBP.1 DPNI.1 DPMAC.1
+ DPMCP.2 DPIO.2
+ DPMCP.3
+
+Hardware objects can be created and destroyed dynamically, providing
+the ability to hot plug/unplug objects in and out of the DPRC.
+
+A DPRC has a mappable MMIO region (an MC portal) that can be used
+to send MC commands. It has an interrupt for status events (like
+hotplug).
+All objects in a container share the same hardware "isolation context".
+This means that with respect to an IOMMU the isolation granularity
+is at the DPRC (container) level, not at the individual object
+level.
+
+DPRCs can be defined statically and populated with objects
+via a config file passed to the MC when firmware starts it.
+
+DPAA2 Objects for an Ethernet Network Interface
+-----------------------------------------------
+
+A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX
+queuing mechanisms, configuration mechanisms, buffer management,
+physical ports, and interrupts. DPAA2 uses a more granular approach
+utilizing multiple hardware objects. Each object provides specialized
+functions. Groups of these objects are used by software to provide
+Ethernet network interface functionality. This approach provides
+efficient use of finite hardware resources, flexibility, and
+performance advantages.
+
+The diagram below shows the objects needed for a simple
+network interface configuration on a system with 2 CPUs.
+
+::
+
+ +---+---+ +---+---+
+ CPU0 CPU1

+ +---+---+
+ |
+ |

+ DPMAC
+ +---+---+
+ |
+ port/PHY
+
+Below the objects are described. For each object a brief description
+is provided along with a summary of the kinds of operations the object
+supports and a summary of key resources of the object (MMIO regions
+and IRQs).
+
+DPMAC (Datapath Ethernet MAC)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Represents an Ethernet MAC, a hardware device that connects to an Ethernet
+PHY and allows physical transmission and reception of Ethernet frames.
+
+- MMIO regions: none
+- IRQs: DPNI link change
+- commands: set link up/down, link config, get stats,
+ IRQ config, enable, reset
+
+DPNI (Datapath Network Interface)
+Contains TX/RX queues, network interface configuration, and RX buffer pool
+configuration mechanisms. The TX/RX queues are in memory and are identified
+by queue number.
+
+- MMIO regions: none
+- IRQs: link state
+- commands: port config, offload config, queue config,
+ parse/classify config, IRQ config, enable, reset
+
+DPIO (Datapath I/O)
+~~~~~~~~~~~~~~~~~~~
+Provides interfaces to enqueue and dequeue
+packets and do hardware buffer pool management operations. The DPAA2
+architecture separates the mechanism to access queues (the DPIO object)
+from the queues themselves. The DPIO provides an MMIO interface to
+enqueue/dequeue packets. To enqueue something a descriptor is written
+to the DPIO MMIO region, which includes the target queue number.
+There will typically be one DPIO assigned to each CPU. This allows all
+CPUs to simultaneously perform enqueue/dequeued operations. DPIOs are
+expected to be shared by different DPAA2 drivers.
+
+- MMIO regions: queue operations, buffer management
+- IRQs: data availability, congestion notification, buffer
+ pool depletion
+- commands: IRQ config, enable, reset
+
+DPBP (Datapath Buffer Pool)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Represents a hardware buffer pool.
+
+- MMIO regions: none
+- IRQs: none
+- commands: enable, reset
+
+DPMCP (Datapath MC Portal)
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+Provides an MC command portal.
+Used by drivers to send commands to the MC to manage
+objects.
+
+- MMIO regions: MC command portal
+- IRQs: command completion
+- commands: IRQ config, enable, reset
+
+Object Connections
+==================
+Some objects have explicit relationships that must
+be configured:
+
+- DPNI <--> DPMAC
+- DPNI <--> DPNI
+- DPNI <--> L2-switch-port
+
+ A DPNI must be connected to something such as a DPMAC,
+ another DPNI, or L2 switch port. The DPNI connection
+ is made via a DPRC command.
+
+::
+
+ +-------+ +-------+
+ | DPNI | | DPMAC |
+ +---+---+ +---+---+
+ | |
+ +==========+
+
+- DPNI <--> DPBP
+
+ A network interface requires a 'buffer pool' (DPBP
+ object) which provides a list of pointers to memory
+ where received Ethernet data is to be copied. The
+ Ethernet driver configures the DPBPs associated with
+ the network interface.
+
+Interrupts
+==========
+All interrupts generated by DPAA2 objects are message
+interrupts. At the hardware level message interrupts
+generated by devices will normally have 3 components--
+1) a non-spoofable 'device-id' expressed on the hardware
+bus, 2) an address, 3) a data value.
+
+In the case of DPAA2 devices/objects, all objects in the
+same container/DPRC share the same 'device-id'.
+For ARM-based SoC this is the same as the stream ID.
+
+
+DPAA2 Linux Drivers Overview
+============================
+
+This section provides an overview of the Linux kernel drivers for
+DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure"
+drivers and 2) functional object drivers (such as Ethernet).
+
+As described previously, a DPRC is a container that holds the other
+types of DPAA2 objects. It is functionally similar to a plug-and-play
+bus controller.
+Each object in the DPRC is a Linux "device" and is bound to a driver.
+The diagram below shows the Linux drivers involved in a networking
+scenario and the objects bound to each driver. A brief description
+of each driver follows.
+
+::
+
+ +------------+
+ | OS Network |
+ | Stack |
+ +------------+ +------------+
+ | Allocator |. . . . . . . | Ethernet |
+ |(DPMCP,DPBP)| | (DPNI) |

+ DPIO |
+ | |
+ DPNI---DPBP |
+ | |
+ DPMAC |
+ | |
+ PHY ---------------+
+ ============================================|========================
+
+A brief description of each driver is provided below.
+
+MC-bus driver
+-------------
+The MC-bus driver is a platform driver and is probed from a
+node in the device tree (compatible "fsl,qoriq-mc") passed in by boot
+firmware. It is responsible for bootstrapping the DPAA2 kernel
+infrastructure.
+Key functions include:
+
+- registering a new bus type named "fsl-mc" with the kernel,
+ and implementing bus call-backs (e.g. match/uevent/dev_groups)
+- implementing APIs for DPAA2 driver registration and for device
+ add/remove
+- creates an MSI IRQ domain
+- doing a 'device add' to expose the 'root' DPRC, in turn triggering
+ a bind of the root DPRC to the DPRC driver
+
+The binding for the MC-bus device-tree node can be consulted at
+*Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt*.
+The sysfs bind/unbind interfaces for the MC-bus can be consulted at
+*Documentation/ABI/testing/sysfs-bus-fsl-mc*.
+
+DPRC driver
+-----------
+The DPRC driver is bound to DPRC objects and does runtime management
+of a bus instance. It performs the initial bus scan of the DPRC
+and handles interrupts for container events such as hot plug by
+re-scanning the DPRC.
+
+Allocator
+---------
+Certain objects such as DPMCP and DPBP are generic and fungible,
+and are intended to be used by other drivers. For example,
+the DPAA2 Ethernet driver needs:
+
+- DPMCPs to send MC commands, to configure network interfaces
+- DPBPs for network buffer pools
+
+The allocator driver registers for these allocatable object types
+and those objects are bound to the allocator when the bus is probed.
+The allocator maintains a pool of objects that are available for
+allocation by other DPAA2 drivers.
+
+DPIO driver
+-----------
+The DPIO driver is bound to DPIO objects and provides services that allow
+other drivers such as the Ethernet driver to enqueue and dequeue data for
+their respective objects.
+Key services include:
+
+- data availability notifications
+- hardware queuing operations (enqueue and dequeue of data)
+- hardware buffer pool management
+
+To transmit a packet the Ethernet driver puts data on a queue and
+invokes a DPIO API. For receive, the Ethernet driver registers
+a data availability notification callback. To dequeue a packet
+a DPIO API is used.
+There is typically one DPIO object per physical CPU for optimum
+performance, allowing different CPUs to simultaneously enqueue
+and dequeue data.
+
+The DPIO driver operates on behalf of all DPAA2 drivers
+active in the kernel-- Ethernet, crypto, compression,
+etc.
+
+Ethernet driver
+---------------
+The Ethernet driver is bound to a DPNI and implements the kernel
+interfaces needed to connect the DPAA2 network interface to
+the network stack.
+Each DPNI corresponds to a Linux network interface.
+
+MAC driver
+----------
+An Ethernet PHY is an off-chip, board specific component and is managed
+by the appropriate PHY driver via an mdio bus. The MAC driver
+plays a role of being a proxy between the PHY driver and the
+MC. It does this proxy via the MC commands to a DPMAC object.
+If the PHY driver signals a link change, the MAC driver notifies
+the MC via a DPMAC command. If a network interface is brought
+up or down, the MC notifies the DPMAC driver via an interrupt and
+the driver can take appropriate action.

- *
- * A workitems is deferred work with these semantics:
- * - a workitem always runs in thread context.
- * - a workitem can be concurrent with other workitems but is strictly
- * serialized with respect to itself.
- * - no CPU affinity, a workitem does not necessarily run on the same CPU
- * that schedules it. However, this might change in the future.
- * - if a workitem is scheduled again before it has a chance to run, it
- * runs only once.
- * - if a workitem is scheduled while it runs, it runs again after it
- * completes; this ensures that events occurring while other events are
- * being processed receive due attention. This behavior also allows a
- * workitem to reschedule itself.
- *
- * Usage notes:
- * - a workitem can sleep but it should be aware of how that sleep might
- * affect others.
- * - a workitem runs inside a kernel thread so there's no user space to access.
- * - do not use a workitem if the scheduling latency can't be tolerated.
- *
- * When wi_action returns non-zero, it means the workitem has either been
- * freed or reused and workitem scheduler won't touch it any more.

+See ABI/sysfs-bus-most.txt
+ Section 2.2 Routing Channels
- Section 3 USB Padding
+To connect a configured channel to a certain core component and make it
+accessible for user space applications, the driver attribute 'add_link' is
+used. The configuration string passed to it has the following format:
-When transceiving synchronous or isochronous data, the number of packets per USB
-transaction and the sub-buffer size need to be configured. These values
-are needed for the driver to process buffer padding, as expected by hardware,
-which is for performance optimization purposes of the USB transmission.
+ "device_name:channel_name:component_name:link_name[.param]"
-When transmitting synchronous data the allocated channel width needs to be
-written to 'set_subbuffer_size'. Additionally, the number of MOST frames that
-should travel to the host within one USB transaction need to be written to
-'packets_per_xact'.
+It is the concatenation of up to four substrings separated by a colon. The
+substrings contain the names of the MOST interface, the channel, the
+component driver and a custom name with which the link is going to be
+referenced with. Since some components need additional information, the
+link name can be extended with a component-specific parameter (separated by
+a dot). In case the character device component is loaded, the handle would
+also appear as a device node in the /dev directory.
-Internally the synchronous threshold is calculated as follows:
+Cdev component example:
+ $ echo "mdev0:ep_81:cdev:my_rx_channel" >$(DRV_DIR)/add_link
- frame_size = set_subbuffer_size * packets_per_xact
-In case 'packets_per_xact' is set to 0xFF the maximum number of packets,
-allocated within one MOST frame, is calculated that fit into _one_ 512 byte
-USB full packet.
+Sound component example:
- frame_size = floor(MTU_USB / bandwidth_sync) * bandwidth_sync
+The sound component needs an additional parameter to determine the audio
+resolution that is going to be used. The following formats are available:
-This frame_size is the number of synchronous data within an USB transaction,
-which renders MTU_USB - frame_size bytes for padding.
+ - "1x8" (Mono)
+ - "2x16" (16-bit stereo)
+ - "2x24" (24-bit stereo)
+ - "2x32" (32-bit stereo)
+ - "6x16" (16-bit surround 5.1)
-When transmitting isochronous AVP data the desired packet size needs to be
-written to 'set_subbuffer_size' and hardware will always expect two isochronous
-packets within one USB transaction. This renders
+ $ echo "mdev0:ep_81:sound:most51_playback.6x16" >$(DRV_DIR)/add_link
- MTU_USB - (2 * set_subbuffer_size)
-bytes for padding.
-
-Note that at least 2 times set_subbuffer_size bytes for isochronous data or
-set_subbuffer_size times packts_per_xact bytes for synchronous data need to be
-put in the transmission buffer and passed to the driver.
-Since HDMs are allowed to change a chosen configuration to best fit its
-constraints, it is recommended to always double check the configuration and read
-back the previously written files.
+ Section 2.3 USB Padding
+When transceiving synchronous or isochronous data, the number of packets
+per USB transaction and the sub-buffer size need to be configured. These
+values are needed for the driver to process buffer padding, as expected by
+hardware, which is for performance optimization purposes of the USB
+transmission.
+When transmitting synchronous data the allocated channel width needs to be
+written to 'set_subbuffer_size'. Additionally, the number of MOST frames
+that should travel to the host within one USB transaction need to be
+written to 'packets_per_xact'.
- Section 4 Routing Channels
+The driver, then, calculates the synchronous threshold as follows:
-To connect a channel that has been configured as outlined above to an AIM and
-make it accessible to user space applications, the attribute file 'add_link' is
-used. To actually bind a channel to the AIM a string needs to be written to the
-file that complies with the following syntax:
+ frame_size = set_subbuffer_size * packets_per_xact
- "most_device:channel_name:link_name[.param]"
+In case 'packets_per_xact' is set to 0xFF the maximum number of packets,
+allocated within one MOST frame, is calculated that fit into _one_ 512 byte
+USB full packet.
-The example above links the channel "channel_name" of the device "most_device"
-to the AIM. In case the AIM interfaces the VFS this would also create a device
-node "link_name" in the /dev directory. The parameter "param" is an AIM dependent
-string, which can be omitted in case the used AIM does not make any use of it.
+ frame_size = floor(MTU_USB / bandwidth_sync) * bandwidth_sync
-Cdev AIM example:
- $ echo "mdev0:ep_81:my_rx_channel" >add_link
- $ echo "mdev0:ep_81" >add_link
+This frame_size is the number of synchronous data within an USB
+transaction, which renders MTU_USB - frame_size bytes for padding.
+When transmitting isochronous AVP data the desired packet size needs to be
+written to 'set_subbuffer_size' and hardware will always expect two
+isochronous packets within one USB transaction. This renders
-Sound/ALSA AIM example:
+ MTU_USB - (2 * set_subbuffer_size)
-The sound/ALSA AIM needs an additional parameter to determine the audio resolution
-that is going to be used. The following strings can be used:
+bytes for padding.
- - "1x8" (Mono)
- - "2x16" (16-bit stereo)
- - "2x24" (24-bit stereo)
- - "2x32" (32-bit stereo)
+Note that at least (2 * set_subbuffer_size) bytes for isochronous data or
+(set_subbuffer_size * packts_per_xact) bytes for synchronous data need to
+be put in the transmission buffer and passed to the driver.
- $ echo "mdev0:ep_81:audio_rx.2x16" >add_link
- $ echo "mdev0:ep_81" >add_link
+Since adapter drivers are allowed to change a chosen configuration to best
+fit its constraints, it is recommended to always double check the
+configuration and read back the previously written files.
