2022-11-09drm/i915/display: move struct intel_link_m_n to intel_display_types.hJani Nikula
struct intel_crtc_state in intel_display_types.h actually needs the struct intel_link_m_n definition, while intel_display.h only needs the forward declaration.

2022-11-03drm/i915: Use intel_crtc_needs_modeset() moreVille Syrjälä
Prefer our own intel_crtc_needs_modeset() wrapper to drm_atomic_crtc_needs_modeset() whenever we are dealing with the intel_ types instead of drm_ types. Makes things a bit neater in general.

2022-11-03drm/i915: Share {csc,gamma}_enable calculation for ilk/snb vs. ivb+Ville Syrjälä
ilk/snb vs. ivb+ hardware is mostly identical except for the addition of the split gamma mode on ivb. Thus we can share the csc_enable and gamma_enable calculation for both variants. Pull that stuff into a few helpers. Note that this also fills in the missing ctm/degamma stuff into ilk_color_check() pretty much, so for good measure let's also add a few extra checks relating to that, although we still don't expose ctm/degamma to userspace. But now it'll be trivial to do so if we wish.

2022-11-01drm/i915/psr: Send update also on invalidateJouni Högander
Currently we are observing mouse cursor stuttering when using xrandr --scaling=1.2x1.2. X scaling/transformation seems to be doing fronbuffer rendering. When moving mouse cursor X seems to perform several invalidates and only one DirtyFB. I.e. it seems to be assuming updates are sent to panel while drawing is done. Earlier we were disabling PSR in frontbuffer invalidate call back (when drawing in X started). PSR was re-enabled in frontbuffer flush callback (dirtyfb ioctl). This was working fine with X scaling/transformation. Now we are just enabling continuous full frame (cff) in PSR invalidate callback. Enabling cff doesn't trigger any updates. It just configures PSR to send full frame when updates are sent. I.e. there are no updates on screen before PSR flush callback is made. X seems to be doing several updates in frontbuffer before doing dirtyfb ioctl. Fix this by sending single update on every invalidate callback.

TODO not sure we actually want these since we don't even rely on the hw ELD buffer, and these might be there just to give the audio side a bit of time to respond to the unsol events.

2022-10-27drm/i915/audio: Use intel_de_rmw() for most audio registersVille Syrjälä
The audio code does a lot of RMW accesses. Utilize intel_de_rmw() to make that a bit less tedious. There are still some hand rolled RMW left, but those have a lot of code in between the read and write to calculate the new value, so would need some refactoring first. v2: Add parens around the ?: to satisfy the robot Cc: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Cc: Kai Vehmanen <kai.vehmanen@linux.intel.com> Cc: Takashi Iwai <tiwai@suse.de> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221026170150.2654-13-ville.syrjala@linux.intel.com

2022-10-27drm/i915/audio: Make sure we write the whole ELD bufferVille Syrjälä
Currently we only write as many dwords into the hardware ELD buffers as drm_eld_size() tells us. That could mean the remainder of the hardware buffer is left with whatever stale garbage it had before, which doesn't seem entirely great. Let's zero out the remainder of the buffer in case the provided ELD doesn't fill it fully. We can also sanity check out idea of the hardware ELD buffer's size by making sure the address wrapped back to zero once we wrote the entire buffer.

2022-10-27drm/i915/audio: Read ELD buffer size from hardwareVille Syrjälä
We currently read the ELD buffer size from hardware on g4x, but on ilk+ we just hardcode it to 84 bytes. Let's unify this and just do the hardware readout on all platforms, in case the size changes in the future or something. TODO: should perhaps do the readout during driver init and stash the results somewhere so that we could check that the connector's ELD actually fits and not even try to enable audio in that case... v2: Document the size is in dwords (Jani) Cc: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Cc: Kai Vehmanen <kai.vehmanen@linux.intel.com> Cc: Takashi Iwai <tiwai@suse.de> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221026170150.2654-10-ville.syrjala@linux.intel.com

2022-10-27drm/i915/audio: Protect singleton register with a lockVille Syrjälä
On the "ilk" platforms AUD_CNTL_ST2 is a singleton. Protect it with the audio mutex in case we ever want to do parallel RMW access to it. Currently that should not happen since we only do audio enable/disable from full modesets, and those are fully serialized. But we probably want to think about toggling audio on/off from fastsets too. The hsw codepaths already have the same locking. g4x should not need it since it can only do audio to a single port at a time, which means it's actually broken in more ways than this atm.
