| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some AC97 codec and board combinations that have been observed to take a very long time to respond after the cold reset has completed. In one case, more than 350 ms was required. To allow users to have sound on those platforms, we'll wait up to 500ms for the codec to become ready. As a board may have multiple codecs, with some faster than others to reset, we add a module parameter to inform the driver which codecs should be present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SigmaDSP firmware loader currently does not perform enough boundary size checks when processing the firmware. As a result it is possible that a malformed firmware can cause an out of bounds memory access.
