https://bugzilla.kernel.org/show_bug.cgi?id=42782 --- Comment #11 from Reartes Guillermo <rtguille@xxxxxxxxx> 2012-06-26 15:11:16 --- I booted with iommu=pt kernel parameter and i stopped getting these messages. I am experimenting with pcie kvm pass-through, so i ended using that parameter. Sadly the whole host freezes when i power on the guest, but that is outside of this bug-report. > In my case, it only happens at POWER-ON, not when doing a RESET. > So to reproduce it one must POWER-CYCLE. I don't think that was actually not 100% accurate. ~~~~~~~~ # dmesg| grep -i amd-vi [ 1.774021] AMD-Vi: device: 00:00.2 cap: 0040 seg: 0 flags: 3e info 1300 [ 1.774024] AMD-Vi: mmio-addr: 00000000feb20000 [ 1.774259] AMD-Vi: DEV_SELECT_RANGE_START devid: 00:00.0 flags: 00 [ 1.774262] AMD-Vi: DEV_RANGE_END devid: 00:00.2 [ 1.774264] AMD-Vi: DEV_SELECT devid: 00:02.0 flags: 00 [ 1.774266] AMD-Vi: DEV_SELECT_RANGE_START devid: 01:00.0 flags: 00 [ 1.774268] AMD-Vi: DEV_RANGE_END devid: 01:00.1 [ 1.774270] AMD-Vi: DEV_SELECT devid: 00:04.0 flags: 00 [ 1.774272] AMD-Vi: DEV_SELECT devid: 02:00.0 flags: 00 [ 1.774274] AMD-Vi: DEV_SELECT devid: 00:05.0 flags: 00 [ 1.774275] AMD-Vi: DEV_SELECT devid: 03:00.0 flags: 00 [ 1.774277] AMD-Vi: DEV_SELECT devid: 00:06.0 flags: 00 [ 1.774279] AMD-Vi: DEV_SELECT devid: 04:00.0 flags: 00 [ 1.774281] AMD-Vi: DEV_SELECT devid: 00:09.0 flags: 00 [ 1.774283] AMD-Vi: DEV_SELECT devid: 05:00.0 flags: 00 [ 1.774284] AMD-Vi: DEV_SELECT devid: 00:11.0 flags: 00 [ 1.774286] AMD-Vi: DEV_SELECT_RANGE_START devid: 00:12.0 flags: 00 [ 1.774288] AMD-Vi: DEV_RANGE_END devid: 00:12.2 [ 1.774290] AMD-Vi: DEV_SELECT_RANGE_START devid: 00:13.0 flags: 00 [ 1.774292] AMD-Vi: DEV_RANGE_END devid: 00:13.2 [ 1.774294] AMD-Vi: DEV_SELECT devid: 00:14.0 flags: d7 [ 1.774296] AMD-Vi: DEV_SELECT devid: 00:14.3 flags: 00 [ 1.774297] AMD-Vi: DEV_SELECT devid: 00:14.4 flags: 00 [ 1.774300] AMD-Vi: DEV_ALIAS_RANGE devid: 06:00.0 flags: 00 devid_to: 00:14.4 [ 1.774302] AMD-Vi: DEV_RANGE_END devid: 06:1f.7 [ 1.774311] AMD-Vi: DEV_SELECT devid: 00:14.5 flags: 00 [ 1.774313] AMD-Vi: DEV_SELECT devid: 00:15.0 flags: 00 [ 1.774315] AMD-Vi: DEV_SELECT devid: 07:00.0 flags: 00 [ 1.774317] AMD-Vi: DEV_SELECT devid: 00:15.1 flags: 00 [ 1.774319] AMD-Vi: DEV_SELECT devid: 08:00.0 flags: 00 [ 1.774320] AMD-Vi: DEV_SELECT_RANGE_START devid: 00:16.0 flags: 00 [ 1.774322] AMD-Vi: DEV_RANGE_END devid: 00:16.2 [ 1.774428] AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40 [ 1.827755] AMD-Vi: Initialized for Passthrough Mode -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
