dmesg drm-intel-nightly drm.debug=0x1e dmesg when suspending and then resuming again
Here's everything new in dmesg after suspending and then resuming again.
This might be the same bug, I'm not sure: https://bugs.freedesktop.org/show_bug.cgi?id=93555 It made me test with i915.enable_psr=0, but that made no difference - the screen still stays black. Tested again with new BIOS, version 1.12.14 compiled 31.08.2016. Tested again with new BIOS, version 1.12.14 compiled 31.08.2016. Did not work. Tested again with this version of drm-intel-nightly: commit 5b633f423e27af3a7f30d303e243f5a2e82917ae Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Oct 18 14:27:24 2016 +0100 drm-intel-nightly: 2016y-10m-18d-13h-24m-11s UTC integration manifest and then booting with intel_iommu=igfx_off (because of https://bugs.freedesktop.org/show_bug.cgi?id=98309). Now suspend works! Is this still a bug?

Mads - there have been quite a few code blocks submitted to drm-tip affecting this area. Can you please retest with the latest kernel (preferable drm-tip from git://anongit.freedesktop.org/git/drm-tip) without igfx_off. If failure is still valid then mark status REOPENED, and attach the latest dmesg. Note also the question on comment 7.

Tested this drm-tip commit: commit 1b757084743a73fa672e92b4e5cf00a291667dfc Author: Jani Nikula <jani.nikula@intel.com> Date: Wed Apr 19 15:50:51 2017 +0300 drm-tip: 2017y-04m-19d-12h-50m-15s UTC integration manifest Booted without intel_iommu=igfx_off - and things actually seems to work! The screen turns on again, both with and without external monitors connected :) Would be wonderful if more people could test so we know that it's not just a fluke. Nice work! Just FYI, my Dell XPS 15 9550 has BIOS version: 1.2.18 (I know .19 is out, but haven't tried with that yet...) Marking as resolved+fixed. Let's see if get tested-by from anybody before actually closing this. |

Created attachment 125550 [details] dmesg drm-intel-nightly drm.debug=0x1e before suspend When resuming my Dell XPS 15 9550 from a suspend, the monitor won't turn on again. Tested all quirks available from pm-suspend, it does not work. It's not related to X11, it happens also if you suspend without starting X. The machine also has an 960M nVIDIA card, but the module is not loaded, and the card is turned off with the help of the bbswitch module. Have tested with the nvidia driver loaded, it makes no difference. No physical output on the laptop is wired to the nVIDIA card (tested with starting X with only nvidia loaded, it shows no outputs available). Tested both vanilla linux-kernel-4.7.0 and latest drm-intel-nightly (currently at 4ef516d46da2ae7091ef0b0b8d05f600d2e85ab8). Nothing seems to happen in dmesg with vanilla kernel, but that was tested without drm.debug=0x1e log_buf_len=1M. It also gets no error state after resuming from suspend: # cat /sys/class/drm/card0/error no error state collected # lspci: 00:00.0 Host bridge: Intel Corporation Skylake Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Skylake PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) 00:04.0 Signal processing controller: Intel Corporation Skylake Processor Thermal Subsystem (rev 07) 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-H Thermal subsystem (rev 31) 00:15.0 Signal processing controller: Intel Corporation Sunrise Point-H Serial IO I2C Controller #0 (rev 31) 00:15.1 Signal processing controller: Intel Corporation Sunrise Point-H Serial IO I2C Controller #1 (rev 31) 00:16.0 Communication controller: Intel Corporation Sunrise Point-H CSME HECI #1 (rev 31) 00:17.0 SATA controller: Intel Corporation Sunrise Point-H SATA Controller [AHCI mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #1 (rev f1) 00:1c.1 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #2 (rev f1) 00:1d.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #9 (rev f1) 00:1d.4 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #13 (rev f1) 00:1d.6 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #15 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-H LPC Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-H PMC (rev 31) 00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31) 00:1f.4 SMBus: Intel Corporation Sunrise Point-H SMBus (rev 31) 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev ff) 02:00.0 Network controller: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC (rev 01) 03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
