The rest of the API (*::analyseStatus) returns NOT_SUPPORTED
when the legacy API returns -ENOSYS.
setParameter legacy -> treble shim did not follow this
conversion due to the legacy API stating that for get_paramers,
-ENOSYS should be returned if
"the implementation does not accept a parameter change while the
output is active but the parameter is acceptable otherwise",
aka INVALID_STATE.
Thus setParameter shim used to return
- OK for OK
- INVALID_STATE for -ENOSYS
- INVALID_ARGUMENTS for everything else
This leads to several problems:
- an implementation of the legacy API can not report NOT_SUPPORTED
- is inconsistent with the rest of the status_t conversion methods
- shim methods implemented over getParameter can not distinguish
failures error required by the .hal documentation
Most importantly, on the system side, the Result is transformed to a
status_t again but without any special logic for methods wrapping
getParameter in the shim.
See: analyzeResult in
frameworks/av/media/libaudiohal/2.0/ConversionHelperHidl.cpp
This can not be changed as the system can not know which methods
are implemented with a legacy wrapper under the Treble API boundary.
This mean that if:
- hal return -ENOSYS ()
- shim converts it to INVALID_STATE
- libaudiohal converts it to NOT_ENOUGH_DATA ()
Thus the checkForNewParameter_l's "status == INVALID_OPERATION"
test in frameworks/av/services/audioflinger/Threads.cpp
are now always false and broken.
This has been broken since the introduction of the Treble shim for O.
Thus setParam now converts status_t to Result in the same way
as all the other shim methods.
