2020-01-23drm/i915/audio: convert to struct drm_device logging macros.Wambui Karuga
Converts the printk based logging macros in i915/display/intel_audio.c to the struct drm_device based logging macros. This transformation was achieved using the following coccinelle script that matches the existence of the struct drm_i915_private device: @rule1@ identifier fn, T; @@ fn(struct drm_i915_private *T,...) { <+... ( -DRM_INFO( +drm_info(&T->drm, ...) | -DRM_ERROR( +drm_err(&T->drm, ...) | -DRM_WARN( +drm_warn(&T->drm, ...) | -DRM_DEBUG( +drm_dbg(&T->drm, ...) | -DRM_DEBUG_DRIVER( +drm_dbg(&T->drm, ...) | -DRM_DEBUG_KMS( +drm_dbg_kms(&T->drm, ...) ) ...+> } @rule2@ identifier fn, T; @@ fn(...) { ... struct drm_i915_private *T = ...; <+...

2020-01-06drm/i915: Limit audio CDCLK>=2*BCLK constraint back to GLK onlyKai Vehmanen
Revert changes done in commit f6ec9483091f ("drm/i915: extend audio CDCLK>=2*BCLK constraint to more platforms"). Audio drivers communicate with i915 over HDA bus multiple times during system boot-up and each of these transactions result in matching get_power/put_power calls to i915, and depending on the platform, a modeset change causing visible flicker. GLK is the only platform with minimum CDCLK significantly lower than BCLK, and thus for GLK setting a higher CDCLK is mandatory. For other platforms, minimum CDCLK is close but below 2*BCLK (e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint should be set, but in practise no communication errors have been reported and the downside if set is the flicker observed at boot-time. Revert to old behaviour until better mechanism to manage probe-time clocks is available. The full CDCLK>=2*BCLK constraint is still enforced at pipe enable time in intel_crtc_compute_min_cdclk().

2019-10-24drm/i915: Rework global state lockingVille Syrjälä
So far we've sort of protected the global state under dev_priv with the connection_mutex. I wan to change that so that we can change the cdclk even for pure plane updates. To that end let's formalize the protection of the global state to follow what I started with the cdclk code already (though not entirely properly) such that any crtc mutex will suffice as a read lock, and all crtcs mutexes act as the write lock. We'll also pimp intel_atomic_state_clear() to clear the entire global state, so that we don't accidentally leak stale information between the locking retries. As a slight optimization we'll only lock the crtc mutexes to protect the global state, however if and when we actually have to poke the hw (eg. if the actual cdclk changes) we must serialize commits across all crtcs so that a parallel nonblocking commit can't get ahead of the cdclk reprogamming. We do that by adding all crtcs to the state. TODO: the old global state examined during commit may still be a problem since it always looks at the _latest_ swapped state in dev_priv. Need to add proper old/new state for that too I think. v2: Remeber to serialize the commits if necessary Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191015193035.25982-3-ville.syrjala@linux.intel.com Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

2019-10-04drm/i915: Fix audio power up sequence for gen10+ displayKai Vehmanen
On platfroms with gen10+ display, driver must set the enable bit of AUDIO_PIN_BUF_CTL register before transactions with the HDA controller can proceed. Add setting this bit to the audio power up sequence. Failing to do this resulted in errors during display audio codec probe, and failures during resume from suspend. Note: We may also need to disable the bit afterwards, but there are still unresolved issues with that.
