The failed case is KBL hang. This patch shouldn't impact platforms that have non-zero num_pipes. So the KBL hang isn't a regression caused by this patch. According to below kernel log before hang (https://intel-gfx-ci.01.org/CI/Patchwork_3266/fi-kbl-7500u/dmesg-during.log), It should be the same issue as Bug 98670 - [BAT] WARN_ON(dev_priv->gt.awake) during drv_module_reload_basic (https://bugs.freedesktop.org/show_bug.cgi?id=98670), [ 25.000193] ------------[ cut here ]------------ [ 25.000227] WARNING: CPU: 3 PID: 6396 at drivers/gpu/drm/i915/i915_gem.c:4241 i915_gem_suspend+0x181/0x190 [i915] [ 25.000228] WARN_ON(dev_priv->gt.awake) [ 25.000229] Modules linked in: [ 25.000231] i915(-) snd_hda_codec_hdmi snd_hda_codec_realtek x86_pkg_temp_thermal intel_powerclamp snd_hda_codec_generic coretemp crct10dif_pclmul crc32_pclmul ghash_clmulni_intel snd_hda_codec snd_hwdep snd_hda_core snd_pcm mei_me mei e1000e ptp pps_core i2c_hid [last unloaded: snd_hda_intel] [ 25.000249] CPU: 3 PID: 6396 Comm: drv_module_relo Tainted: G U 4.9.0-rc8-CI-Patchwork_3266+ #1 [ 25.000250] Hardware name: GIGABYTE GB-BKi7A-7500/MFLP7AP-00, BIOS F1 07/27/2016 [ 25.000252] ffffc90000547d18 ffffffff81435bf5 ffffc90000547d68 0000000000000000 [ 25.000256] ffffc90000547d58 ffffffff8107e4d6 0000109100000000 ffff880257a30000 [ 25.000259] 0000000000000000 ffff880257a30068 ffffffffa01370c0 0000000000000000 [ 25.000263] Call Trace: [ 25.000268] [<ffffffff81435bf5>] dump_stack+0x67/0x92 [ 25.000271] [<ffffffff8107e4d6>] __warn+0xc6/0xe0 [ 25.000274] [<ffffffff8107e53a>] warn_slowpath_fmt+0x4a/0x50 [ 25.000298] [<ffffffffa0049a21>] i915_gem_suspend+0x181/0x190 [i915] [ 25.000314] [<ffffffffa0006f4e>] i915_driver_unload+0x1e/0x190 [i915] [ 25.000331] [<ffffffffa0010b24>] i915_pci_remove+0x14/0x20 [i915] [ 25.000334] [<ffffffff81485954>] pci_device_remove+0x34/0xb0 [ 25.000339] [<ffffffff81584d8c>] __device_release_driver+0x9c/0x150 [ 25.000340] [<ffffffff81585906>] driver_detach+0xb6/0xc0 [ 25.000343] [<ffffffff81584823>] bus_remove_driver+0x53/0xd0 [ 25.000345] [<ffffffff815863c7>] driver_unregister+0x27/0x50 [ 25.000347] [<ffffffff814842f5>] pci_unregister_driver+0x25/0x70 [ 25.000375] [<ffffffffa00f55e4>] i915_exit+0x1a/0x71 [i915] [ 25.000378] [<ffffffff8111a863>] SyS_delete_module+0x193/0x1e0 [ 25.000380] [<ffffffff81823d6e>] entry_SYSCALL_64_fastpath+0x1c/0xb1 > -----Original Message----- > From: Intel-gfx [mailto:intel-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf > Of Patchwork > Sent: Friday, December 9, 2016 6:53 PM > To: Wang, Elaine <elaine.wang@xxxxxxxxx> > Cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx > Subject: ✗ Fi.CI.BAT: warning for drm/i915: Respect num_pipes > when install or reset dispaly IRQ > > == Series Details == > > Series: drm/i915: Respect num_pipes when install or reset dispaly IRQ > URL : https://patchwork.freedesktop.org/series/16599/ > State : warning > > == Summary == > > Series 16599v1 drm/i915: Respect num_pipes when install or reset dispaly > IRQ > https://patchwork.freedesktop.org/api/1.0/series/16599/revisions/1/mbox/ > > Test kms_force_connector_basic: > Subgroup force-load-detect: > pass -> DMESG-WARN (fi-ivb-3770) > > fi-bdw-5557u total:247 pass:233 dwarn:0 dfail:0 fail:0 skip:14 > fi-bsw-n3050 total:247 pass:208 dwarn:0 dfail:0 fail:0 skip:39 > fi-bxt-t5700 total:247 pass:220 dwarn:0 dfail:0 fail:0 skip:27 > fi-byt-j1900 total:247 pass:220 dwarn:0 dfail:0 fail:0 skip:27 > fi-byt-n2820 total:247 pass:216 dwarn:0 dfail:0 fail:0 skip:31 > fi-hsw-4770 total:247 pass:228 dwarn:0 dfail:0 fail:0 skip:19 > fi-hsw-4770r total:247 pass:228 dwarn:0 dfail:0 fail:0 skip:19 > fi-ilk-650 total:247 pass:195 dwarn:0 dfail:0 fail:0 skip:52 > fi-ivb-3520m total:247 pass:226 dwarn:0 dfail:0 fail:0 skip:21 > fi-ivb-3770 total:247 pass:225 dwarn:1 dfail:0 fail:0 skip:21 > fi-kbl-7500u total:247 pass:226 dwarn:0 dfail:0 fail:0 skip:21 > fi-skl-6260u total:247 pass:234 dwarn:0 dfail:0 fail:0 skip:13 > fi-skl-6700hq total:247 pass:227 dwarn:0 dfail:0 fail:0 skip:20 > fi-skl-6700k total:247 pass:224 dwarn:3 dfail:0 fail:0 skip:20 > fi-skl-6770hq total:247 pass:234 dwarn:0 dfail:0 fail:0 skip:13 > fi-snb-2520m total:247 pass:216 dwarn:0 dfail:0 fail:0 skip:31 > fi-snb-2600 total:247 pass:215 dwarn:0 dfail:0 fail:0 skip:32 > > de43f4e755c6bf50ad53b4ccacedf9850f42eda4 drm-tip: 2016y-12m-09d-09h- > 01m-58s UTC integration manifest ef0b9fd drm/i915: Respect num_pipes > when install or reset dispaly IRQ > > == Logs == > > For more details see: https://intel-gfx-ci.01.org/CI/Patchwork_3248/ > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/intel-gfx _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
