This issue also exists on eDP + HDMI. Bisect to commit 6c373ca89399c5a3f7ef210ad8f63dc3437da345 but booting fails with huge messages on console. Created attachment 115799 [details]
dmesg on HSW
On HSW, when connect to DP monitor, xinit + S3 will also fail.
exists on drm-intel-testing-2015-05-22 with BSW Created attachment 116109 [details]
dmesg on BDW
This issue still exists on BDW with drm-intel-testing-2015-05-22 kernel Created attachment 116146 [details] [review] Debug patch The "CRTC fixup failed" line in the HSW log indicates intel_crtc_compute_config() fails after resume. And that means the modeset is aborted before the new pipe config is dumped to the log, which would give us a clue as to why it failed. Can you run the test again on HSW with this patch applied, and also with "drm.debug=0x1e log_buf_len=4M" in the kernel command line? Created attachment 116194 [details]
run the test again on HSW with patch applied
Created attachment 116198 [details] [review] Possible fix Could you try if the attached patch fixes the issue? Test with the patch,connect with three monitor(DP,eDP,HDMI),except eDP,the other two can't display. (In reply to xubin from comment #14) > Test with the patch,connect with three monitor(DP,eDP,HDMI),except eDP,the > other two can't display. Can you add dmesg (with debug information) for this failure? I retry on x-hswm24 with HDMI monitor connected. With drm-intel-testing-2015-05-22, after S3, eDP shows X and HDMI is black screen. system is alive. With drm-intel-testing-2015-05-22 + patch, after S3, eDP shows X and HDMI is black screen too. And system hangs. Unfortunately the test machine does not have serial port so there is no dmesg captured. The fix I wrote is superseded by Maarten's latest atomic patch series that has been just merged. Could you test with latest -nightly? Created attachment 116295 [details]
dmesg log with eDP and HDMI connected
I retry latest nightly (commit 0761e2d5d55e8311950514fda1ec414838525985) on x-hswm24 with eDP/HDMI connected, after resuming from S3, both eDP and HDMI are fine.

So that's fixed in nightly, good. But I'm afraid the issue might exist with the drm-intel-next branch. Could you verify? Not yet. I need to double check with BSW. And we find that latest nightly might have a big regression. When boot BSW with both eDP and DP connected, both monitors are black screen. We're double checking to report an new bug. When that issue got fixed, I will check on BSW again. Will update after Bug 90861 got fixed. (In reply to Ander Conselvan de Oliveira from comment #19) > But I'm afraid the issue might exist with the drm-intel-next branch. That should have been drm-intel-next-fixes. *** Bug 90911 has been marked as a duplicate of this bug. *** I tried on BSW for several commits: exist in drm-intel-next-fixes commit bf546f8158e2df2656494a475e6235634121c87c exists in drm-intel-testing-2015-05-22 Fail to boot in latest nightly because of bug 90929 exist in drm-intel-nightly commit d57981d00ed80a859c24fe937c70959dd646e439 (the commit before 3bae26eb2991c00670df377cf6c3bc2b0577e82a) Please retest on current drm-intel-nightly.

dmesg of hsw
Test with the latest drm-intel-nightly kernel(commit 2a36ab374449e3794b4be6be01f1a47cb6ee5b83) on HSW platform with 3 monitor (two DP,one VGA),only one DP can resume normally. Then pkill x ,the three monitor show text mode.

dmesg of bsw
Test with the latest drm-intel-nightly kernel(commit 2a36ab374449e3794b4be6be01f1a47cb6ee5b83) on BSW platform with 3 monitor (one DP,one eDP,one VGA),only eDP can resume normally. Then pkill x ,the three monitor come to text console.
The fix we have in -next-fixes for this will conflict with Maarten's next series of atomic modesetting patches which should also fix this. Test it on BDW with latest drm-intel-next-fixes_4ed9fb_20150618+ kernel, S3 will automatic back, 3 monitors can light up. Has Maarten's fix for this landed? Not yet, it's on the mailing list. Maarten's patches that fix this are in -nightly now. Closing resolved+fixed after 1.5 years of silence. |
