This might be explained by the fact that this is the only machine that has a chamelium connected to its mDP port. The test is supposed to check that one CRTC stealing an already-used encoder is not accepted by atomic. However, in this particular case, the failure happens on the first modeset (the one where we want to try stealing the encoder from). Here is the relevant failure: <7> [23.795360] [drm:drm_mode_setcrtc] [CRTC:82:pipe A] <7> [23.795445] [drm:drm_mode_setcrtc] [CONNECTOR:196:DP-1] <7> [23.795602] [drm:intel_atomic_check [i915]] [CONNECTOR:196:DP-1] Limiting display bpp to 24 instead of EDID bpp 24, requested bpp 36, max platform bpp 36 <7> [23.795668] [drm:intel_dp_compute_config [i915]] DP link computation with max lane count 4 max rate 270000 max bpp 24 pixel clock 533250KHz <7> [23.795731] [drm:intel_dp_compute_config [i915]] Force DSC en = 0 <7> [23.795788] [drm:intel_atomic_check [i915]] Encoder config failure: -22</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
