The driver has been broken and disabled for several kernel versions now.
It doesn't have a maintainer anymore, and most of the people who've
worked on it have moved on. There's also still a long list of issues in
the TODO file before it can be moved out of staging. Until someone can
put in the work to make the driver work again and move it out of
staging, remove it from the kernel.

- Linux DSP/BIOS Bridge release

-DSP/BIOS Bridge overview
-========================
-
-DSP/BIOS Bridge is designed for platforms that contain a GPP and one or more
-attached DSPs. The GPP is considered the master or "host" processor, and the
-attached DSPs are processing resources that can be utilized by applications
-and drivers running on the GPP.
-
-The abstraction that DSP/BIOS Bridge supplies, is a direct link between a GPP
-program and a DSP task. This communication link is partitioned into two
-types of sub-links: messaging (short, fixed-length packets) and data
-streaming (multiple, large buffers). Each sub-link operates independently,
-and features in-order delivery of data, meaning that messages are delivered
-in the order they were submitted to the message link, and stream buffers are
-delivered in the order they were submitted to the stream link.
-
-In addition, a GPP client can specify what inputs and outputs a DSP task
-uses. DSP tasks typically use message objects for passing control and status
-information and stream objects for efficient streaming of real-time data.
-
-GPP Software Architecture
-=========================
-
-A GPP application communicates with its associated DSP task running on the
-DSP subsystem using the DSP/BIOS Bridge API. For example, a GPP audio
-application can use the API to pass messages to a DSP task that is managing
-data flowing from analog-to-digital converters (ADCs) to digital-to-analog
-converters (DACs).
-
-From the perspective of the GPP OS, the DSP is treated as just another
-peripheral device. Most high level GPP OS typically support a device driver
-model, whereby applications can safely access and share a hardware peripheral
-through standard driver interfaces. Therefore, to allow multiple GPP
-applications to share access to the DSP, the GPP side of DSP/BIOS Bridge
-implements a device driver for the DSP.
-
-Since driver interfaces are not always standard across GPP OS, and to provide
-some level of interoperability of application code using DSP/BIOS Bridge
-between GPP OS, DSP/BIOS Bridge provides a standard library of APIs which
-wrap calls into the device driver. So, rather than calling GPP OS specific
-driver interfaces, applications (and even other device drivers) can use the
-standard API library directly.
-
-DSP Software Architecture
-=========================
-
-For DSP/BIOS, DSP/BIOS Bridge adds a device-independent streaming I/O (STRM)
-interface, a messaging interface (NODE), and a Resource Manager (RM) Server.
-The RM Server runs as a task of DSP/BIOS and is subservient to commands
-and queries from the GPP. It executes commands to start and stop DSP signal
-processing nodes in response to GPP programs making requests through the
-(GPP-side) API.
-
-DSP tasks started by the RM Server are similar to any other DSP task with two
-important differences: they must follow a specific task model consisting of
-three C-callable functions (node create, execute, and delete), with specific
-sets of arguments, and they have a pre-defined task environment established
-by the RM Server.
-
-Tasks started by the RM Server communicate using the STRM and NODE interfaces
-and act as servers for their corresponding GPP clients, performing signal
-processing functions as requested by messages sent by their GPP client.
-Typically, a DSP task moves data from source devices to sink devices using
-device independent I/O streams, performing application-specific processing
-and transformations on the data while it is moved. For example, an audio
-task might perform audio decompression (ADPCM, MPEG, CELP) on data received
-from a GPP audio driver and then send the decompressed linear samples to a
-digital-to-analog converter.

- DSP/Bridge Error Code Guide
-
-
-Success code is always taken as 0, except for one case where a success status
-different than 0 can be possible, this is when enumerating a series of dsp
-objects, if the enumeration doesn't have any more objects it is considered as a
-successful case. In this case a positive ENODATA is returned (TODO: Change to
-avoid this case).
-
-Error codes are returned as a negative 1, if an specific code is expected, it
-can be propagated to user space by reading errno symbol defined in errno.h, for
-specific details on the implementation a copy of the standard used should be
-read first.
-
-The error codes used by this driver are:
-
-[EPERM]
- General driver failure.
-
- According to the use case the following might apply:
- - Device is in 'sleep/suspend' mode due to DPM.
- - User cannot mark end of stream on an input channel.
- - Requested operation is invalid for the node type.
- - Invalid alignment for the node messaging buffer.
- - The specified direction is invalid for the stream.
- - Invalid stream mode.
-
-[ENOENT]
- The specified object or file was not found.
-
-[ESRCH]
- A shared memory buffer contained in a message or stream could not be mapped
- to the GPP client process's virtual space.
-
-[EIO]
- Driver interface I/O error.
-
- or:
- - Unable to plug channel ISR for configured IRQ.
- - No free I/O request packets are available.
-
-[ENXIO]
- Unable to find a named section in DSP executable or a non-existent memory
- segment identifier was specified.
-
-[EBADF]
- General error for file handling:
-

- - Unable to read file.
- - An error occurred while parsing the DSP executable file.
-
-[ENOMEM]
- A memory allocation failure occurred.
-
-[EACCES]
- - Unable to read content of DCD data section; this is typically caused by
- improperly configured nodes.
- - Unable to decode DCD data section content; this is typically caused by
- changes to DSP/BIOS Bridge data structures.
- - Unable to get pointer to DCD data section; this is typically caused by
- improperly configured UUIDs.
- - Unable to load file containing DCD data section; this is typically
- caused by a missing COFF file.
- - The specified COFF file does not contain a valid node registration
- section.
-
-[EFAULT]

-
-[EEXIST]
- Attempted to create a channel manager when one already exists.

- the iAlg function table for an xDAIS socket is not found in the COFF file.
- In this case, force the symbol to be linked into the COFF file.
- DSPNode_Create, DSPNode_Execute, and DSPNode_Delete will return this if
- the create, execute, or delete phase function, respectively, could not be
- found in the COFF file.

- * This C header file gives the layout of the data structure created by the
- * dynamic loader to describe the set of modules loaded into the DSP.
- *
- * Linked List Structure:
- * ----------------------
- * The data structure defined here is a singly-linked list. The list
- * represents the set of modules which are currently loaded in the DSP memory.
- * The first entry in the list is a header record which contains a flag
- * representing the state of the list. The rest of the entries in the list
- * are module records.
- *
- * Global symbol _DLModules designates the first record in the list (i.e. the
- * header record). This symbol must be defined in any program that wishes to
- * use DLLview plug-in.
- *
- * String Representation:
- * ----------------------
- * The string names of the module and its sections are stored in a block of
- * memory which follows the module record itself. The strings are ordered:
- * module name first, followed by section names in order from the first
- * section to the last. String names are tightly packed arrays of 8-bit
- * characters (two characters per 16-bit word on the C55x). Strings are
- * zero-byte-terminated.
- *
- * Creating and updating the list:
- * -------------------------------
- * Upon loading a new module into the DSP memory the dynamic loader inserts a
- * new module record as the first module record in the list. The fields of
- * this module record are initialized to reflect the properties of the module.
- * The dynamic loader does NOT increment the flag/counter in the list's header
- * record.
- *
- * Upon unloading a module from the DSP memory the dynamic loader removes the
- * module's record from this list. The dynamic loader also increments the
- * flag/counter in the list's header record to indicate that the list has been
- * changed.
