drm.debug=0x3f log? BAT issue: /archive/results/CI_IGT_test/Patchwork_2031/ These vblank wait timeouts seems to plague the dell xps machine. Could be related to commit 8a292d016d1c ("drm/i915: Make RPS EI/thresholds multiple of 25 on SNB-BDW") since the symptoms I was fixing there seemed to indicate scheduling/timer interrupts getting lost. Perhaps we're still losing vblank interrupts, but to a lesser degree? Playing around with the RPS EI/threshold values a bit more might be warranted. *** Bug 95262 has been marked as a duplicate of this bug. *** Also seen on ro-ivb2-i7-3770 Another failure on BYT/kms_flip/basic-flip-vs-dpms looks similar enough (/archive/results/CI_IGT_test/RO_Patchwork_1335/): [ 459.087969] ------------[ cut here ]------------ [ 459.088252] WARNING: CPU: 1 PID: 7674 at drivers/gpu/drm/i915/intel_display.c:13669 intel_atomic_commit_tail+0x1179/0x1180 [i915] [ 459.088261] pipe B vblank wait timed out [ 459.088266] Modules linked in: snd_hda_intel i915 drm_kms_helper drm snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic intel_powerclamp snd_hda_codec coretemp crct10dif_pclmul crc32_pclmul snd_hwdep ghash_clmulni_intel snd_hda_core snd_pcm lpc_ich i2c_algo_bit syscopyarea sysfillrect sysimgblt fb_sys_fops i2c_hid i2c_designware_platform i2c_designware_core r8169 mii sdhci_acpi sdhci mmc_core [last unloaded: vgem] [ 459.088353] CPU: 1 PID: 7674 Comm: kms_flip Tainted: G U 4.7.0-rc5-gfxbench-RO_Patchwork_1335+ #1 [ 459.088360] Hardware name: \xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff \xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff/DN2820FYK, BIOS FYBYT10H.86A.0053.2016.0205.1707 02/05/2016 [ 459.088366] 0000000000000000 ffff8800b6777ac0 ffffffff8140e495 ffff8800b6777b10 [ 459.088395] 0000000000000000 ffff8800b6777b00 ffffffff8107a996 0000356500000296 [ 459.088421] 0000000000000158 ffff8800366b9158 0000000000000004 0000000000000001 [ 459.088435] Call Trace: [ 459.088449] [<ffffffff8140e495>] dump_stack+0x67/0x92 [ 459.088458] [<ffffffff8107a996>] __warn+0xc6/0xe0 [ 459.088470] [<ffffffff8107a9fa>] warn_slowpath_fmt+0x4a/0x50 [ 459.088487] [<ffffffff810c4719>] ? finish_wait+0x59/0x70 [ 459.088562] [<ffffffffa04a4589>] intel_atomic_commit_tail+0x1179/0x1180 [i915] [ 459.088575] [<ffffffff810d009f>] ? mark_held_locks+0x6f/0xa0 [ 459.088588] [<ffffffff810d01f2>] ? trace_hardirqs_on_caller+0x122/0x1b0 [ 459.088601] [<ffffffff810c48e0>] ? wake_atomic_t_function+0x60/0x60 [ 459.088675] [<ffffffffa04a4a0c>] intel_atomic_commit+0x47c/0x5a0 [i915] [ 459.088703] [<ffffffffa01233c1>] ? __drm_atomic_helper_crtc_duplicate_state+0x51/0xa0 [drm_kms_helper] [ 459.088750] [<ffffffffa036b002>] drm_atomic_commit+0x32/0x50 [drm] [ 459.088776] [<ffffffffa0122ca8>] drm_atomic_helper_connector_dpms+0xe8/0x1a0 [drm_kms_helper] [ 459.088815] [<ffffffffa03582e0>] ? _object_find+0x70/0xe0 [drm] [ 459.088856] [<ffffffffa035f3b4>] drm_mode_obj_set_property_ioctl+0x224/0x230 [drm] [ 459.088894] [<ffffffffa035f3eb>] drm_mode_connector_property_set_ioctl+0x2b/0x30 [drm] [ 459.088924] [<ffffffffa0350b6e>] drm_ioctl+0x13e/0x530 [drm] [ 459.088959] [<ffffffffa035f3c0>] ? drm_mode_obj_set_property_ioctl+0x230/0x230 [drm] [ 459.088970] [<ffffffff811df513>] ? __vfs_read+0x23/0x110 [ 459.088978] [<ffffffff811f2f1e>] do_vfs_ioctl+0x8e/0x660 [ 459.088986] [<ffffffff810e60bd>] ? debug_lockdep_rcu_enabled+0x1d/0x20 [ 459.088994] [<ffffffff811ffe2a>] ? __fget_light+0x6a/0x90 [ 459.089001] [<ffffffff811f352c>] SyS_ioctl+0x3c/0x70 [ 459.089011] [<ffffffff817ad269>] entry_SYSCALL_64_fastpath+0x1c/0xac [ 459.092250] ---[ end trace 0c0033dfddd287b4 ]--- This failure (for kms_pipe_crc_basic@hang-read-crc-pipe-a and kms_flip@basic-flip-vs-dpms) has not been visible in Patchwork Intel GFX CI Testing during last week. I propose this to be closed as Resolved + Worksforme. Please comment if you disagree. I agree both kms_pipe_crc_basic@hang-read-crc-pipe-a and kms_flip@basic-flip-vs-dpms are now passing. Last week we had still failure with hang-read-crc-pipe-a on some platform but now we are getting only a warn message "drm/i915: Resetting chip after gpu hang" for that is expected :) |
