Stripe control verb reports and controls the stripe capability of an Audio Output Converter. This verb needs to be implemented only for an audio output converter and only if the stripe bit of the Audio Widget Capabilities parameter is 1. Stripe control: get code(0xf24) and set code(0x724)
the series look ok (one minor comment on operator precedence) and aligned with my understanding of the HDaudio 1.0a spec.
That said you made no mention of the Stripe bit (figure 86) and fields 22:20 (Stripe capability) in Figure 75, so it's not clear to me if the support added in this patchset is sufficient or if there is additional logic to be set.
Stripe bit is part of Audio Widget Capability parameter and is mentioned above in the last section of background. Patch-5(v2) checks for the stripe bit, before sending stripe control verb.
Ah yes, I thought this patchset added stripe control starting from scratch but some definitions were already present. Thanks for the precision.
As far as stripe control register is concerned (22:20), I don't think any SW programming is required for this.
Yes correct. this is on GET only so something the codec needs to worry about, not the driver.
