* [Intel-gfx] [PATCH] drm/i915/combo_phy: Add Workaround to avoid flicker with HBR3 eDP Panels @ 2022-08-04 10:29 Ankit Nautiyal 2022-08-04 11:41 ` [Intel-gfx] ✗ Fi.CI.BAT: failure for " Patchwork 2022-08-04 15:44 ` [Intel-gfx] [PATCH] " Imre Deak 0 siblings, 2 replies; 4+ messages in thread From: Ankit Nautiyal @ 2022-08-04 10:29 UTC (permalink / raw) To: intel-gfx WA_14014367875 : When Display PHY is configured in continuous DCC calibration mode, the DCC (duty cycle correction) for the clock erroneously goes through a state where the DCC code is 0x00 when it is supposed to be transitioning from 0x10 to 0x0F. This glitch causes a distortion in the clock, which leads to a bit error. The issue is known to be causing flickering with eDP HBR3 panels. The work around configures the DCC in one-time-update mode. This mode updates the DCC code one time during training and then it does not change. This will prevent on-the-fly updates so that the glitch does not occur.
