From ca97f5546f191bf460b3f4b59ade3ea5e7378796 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 9 Apr 2026 13:08:40 +0300 Subject: [PATCH] drm/i915/mst: Call intel_pfit_compute_config() for sharpness filter MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The sharpness filter property is on the CRTC (as opposed to the connector) so the expectation is that it's usable on all output types. Since the sharpness filter is now fully integrateds into the normal pfit code intel_pfit_compute_config() must be called from the encoder .compute_config() on all relevant output types. Sharpness filter is supported on LNL+ so only HDMI and DP SST/MST outputs are actually relevant. I already took care of HDMI and DP SST, but (as usual) forgot about DP MST. Add the missing intel_pfit_compute_config() call to make the sharpness filter operational on DP MST as well.
