It's suitable for userspace implementation to have GObject interface for such features. This patchset adds the interface. The implementation of interface should have four methods; open, get_protocol_version, get_device_info, and create_source. Additionally, it should emit handle-disconnection signal when detecting ENODEV error in the interation of source.

Semantics for _SX controls
by Mark Brown 02 Jun '22

02 Jun '22

Hi, The fixes for input validation have highlighed a bunch of problems with the _SX controls. These aren't widely used, it's just some Cirrus Logic and Qualcomm CODECs plus the obsolte ab8500 driver, but it has become apparent that at least some of the drivers were relying on the lack of validation we used to have to work. For the Cirrus case 34198710f55b5f ("ASoC: Add info callback for SX_TLV controls") says that the intended semantic is Currently every CODEC implementing these controls specifies the minimum as the non-zero value for the minimum and the maximum as the number of gain settings available. which was from Charles at Cirrus so hopefully that's the semantic used by Cirrus drivers. However Tan Nayir pointed at some out of tree patches from Qualcomm which change the info callback such that max is instead the maximum register value that can be written and reports that since we started validating written values properly they can no longer set some valid values in some controls on at least some Qualcomm devices (this was a wcd9340) which clearly indicates that there's some problems that need fixing. This isn't helped by the fact that snd_soc_info_volsw_sx() is implemented by calling snd_soc_info_volsw() and then applying an offset to the maximum value which makes things harder to follow - I think we should make snd_soc_info_volsw_sx() a standalone function, and we probably need some fixes in some combination of the shared functions and the drivers as well. Can people please check how the values in the current drivers correspond to what the actual bitfields in the registers have so we can get a handle on what's going on here? I've pasted a quick grep for _SX controls below: sound/soc/codecs/ab8500-codec.c: SOC_SINGLE_XR_SX("ANC Warp Delay Shift", sound/soc/codecs/ab8500-codec.c: SOC_SINGLE_XR_SX("ANC FIR Output Shift",
