This looks like a bug in the audio driver. I wonder what pipe number it's actually requesting here? (In reply to Ville Syrjala from comment #1) > This looks like a bug in the audio driver. I wonder what pipe number it's > actually requesting here? * places a large bet on -1. Although, RAX: 0000000000000032 suggests 50. When we run test with disable display the num_pipes is set to 0. This is set checked in get_saved_enc() function. The function assumes that we have more than 0 pipes available. I'm testing a patch that caches maximum number of available pipes and uses this value instead of num_pipes. I'm waiting for the intel-trybot results at the moment. fix in trybot good? https://patchwork.freedesktop.org/series/31745/ The bug is that intel_device_info_runtime_init() gets called too late, and num_pipes gets set to 0 too late, and audio component gets registered despite no display. N.b. -1 is a valid value for pipe in the component interface, but that's besides the point. Audio component init already has if (INTEL_INFO(dev_priv)->num_pipes == 0) return; but it has no effect because see comment #6. Quick note: still hit on CFL with IGT-Version: 1.20-g7aac0e8 (x86_64) (Linux: 4.14.0-rc7-drm-intel-qa-ww44-commit-ec9f758+ x86_64) (In reply to Elizabeth from comment #8) > Quick note: still hit on CFL with IGT-Version: 1.20-g7aac0e8 (x86_64) > (Linux: 4.14.0-rc7-drm-intel-qa-ww44-commit-ec9f758+ x86_64) igt@drv_module_reload@basic-no-display igt@drv_module_reload@basic-reload-inject igt@drv_module_reload@basic-reload Forgot tests, sorry for the spam. Adding Vinod, this is something the audio team broke. We're currently freezing the snd-next tree in drm-tip because of this issue, which might be something that you want to avoid (since iirc audio QA still tests drm-tip).

Also FWIW, I do not think anything in sound-next would have broken this, Takashi? (In reply to Daniel Vetter from comment #10) > Adding Vinod, this is something the audio team broke. We're currently > freezing the snd-next tree in drm-tip because of this issue, which might be > something that you want to avoid (since iirc audio QA still tests drm-tip). Well, there has been no change in the fundamental HD-audio code over months, so I don't think it's the audio side that broke -- at least, not in an obvious manner. At which commit of sound git tree did it still work? We can check it by comparing with the broken tree. I proposed a patch https://patchwork.freedesktop.org/series/33506/ which checks if pipes are available when reading out eld. This should fix CFL dmesg warnings. Reviews and comments are warmly welcomed :) Dropping priority as other CI system works https://intel-gfx-ci.01.org/tree/drm-tip/fi-cfl-s2.html Now need to check still with eDP connected.

(In reply to Jani Saarinen from comment #14) > Dropping priority as other CI system works > https://intel-gfx-ci.01.org/tree/drm-tip/fi-cfl-s2.html Jani, could you comment as to why this is set to invalid? It turned out that cfl-s had CNP PCH internal which meant that one of the pipes was fused of. The cfl-s2 has CNP PCH external which has all three pipes enabled. For gen9 only we can fuse off pipes.

OK, let's sweep it under the carpet and hope no one else does this type of crazy CFL home builds. *** Bug 104025 has been marked as a duplicate of this bug. *** There were reports about this in the wild on non-CNP, pushed commit 0b7029b7e43fda1304c181a3ade0b429b9edcd9d Author: Mika Kahola <mika.kahola@intel.com> Date: Mon Dec 18 10:04:03 2017 +0200 drm/i915: Check for fused or unused pipes This issue still happens on Linux 4.15.1 running on a ASRock Mini 110 STX board.
