|
|
|
+
|
|
|
+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:
|
|
|

|
|
|
+ - 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.
|

|
|
+ In this case, force the symbol to be linked into the COFF file.
|
|
|
+ DSPNode_Create, DSPNode_Execute, and DSPNode_Delete will return this if
