Hi Nicolas, Would you be able to send the full IOMMU groups tree for both NUCs? It's nice to see for the record. I was looking at using a Broadwell or Haswell one myself.
Skylake was already out of real consideration for me as I was assuming there would be the same lack of isolation as your're noting. Slightly off topic ... I was leaning towards the Haswell NUC though since apparently only that IGD 4600 supports 3 external monitors via MST hub ... do you know anything about that vis-a-vis the Broadwell and Skylake NUCs? Seems like the NUCs are going backwards as the Intel packages go forward ... :( On Fri, Jan 22, 2016, at 07:26 AM, nicolas prochazka wrote: > Hello, I just need a confimation, with my nuc broadwell I can do > passthrough of my sound card without problem, because of a good > iommu group, but it seems impossible with my new skylake nuc group 7 > is not viable ...... please, tell me that a solution is possible . > Regards, Nicolas > > Broadwell > > [nicolas-hard-365e3600-7279-11e3-91e4-b8aeed728e68]lspci 00:00.0 Host > bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09) > 00:02.0 VGA compatible controller: Intel Corporation Broadwell-U > Integrated Graphics (rev 09) 00:03.0 Audio device: Intel Corporation > Broadwell-U Audio Controller (rev 09) 00:14.0 USB controller: Intel > Corporation Wildcat Point-LP USB xHCI Controller (rev 03) 00:16.0 > Communication controller: Intel Corporation Wildcat Point-LP MEI > Controller #1 (rev 03) 00:19.0 Ethernet controller: Intel Corporation > Ethernet Connection (3) I218-V (rev 03) > 00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High > Definition Audio Controller (rev 03) > 00:1c.0 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express > Root Port #1 (rev e3) > 00:1c.3 PCI bridge: Intel Corporation Wildcat Point-LP PCI Express > Root Port #4 (rev e3) > 00:1d.0 USB controller: Intel Corporation Wildcat Point-LP USB EHCI > Controller (rev 03) > 00:1f.0 ISA bridge: Intel Corporation Wildcat Point-LP LPC Controller > (rev 03) > 00:1f.2 SATA controller: Intel Corporation Wildcat Point-LP SATA > Controller [AHCI Mode] (rev 03) > 00:1f.3 SMBus: Intel Corporation Wildcat Point-LP SMBus Controller > (rev 03) 02:00.0 Network controller: Intel Corporation Wireless > 7265 (rev 59) > > audio /sys/kernel/iommu_groups/3 /sys/kernel/iommu_groups/3/devices > /sys/kernel/iommu_groups/3/devices/0000:00:16.0 > > Now, with my new nuc skylake : [nuc-skylake-9787be61-53d5-1246-cb75- > b8aeed7d8885]lspci 00:00.0 Host bridge: Intel Corporation Sky Lake > Host Bridge/DRAM Registers (rev 09) 00:02.0 VGA compatible controller: > Intel Corporation Sky Lake Integrated Graphics (rev 0a) 00:14.0 USB > controller: Intel Corporation Device 9d2f (rev 21) 00:14.2 Signal > processing controller: Intel Corporation Device 9d31 (rev 21) 00:16.0 > Communication controller: Intel Corporation Device 9d3a (rev 21) > 00:17.0 SATA controller: Intel Corporation Device 9d03 (rev 21) > 00:1c.0 PCI bridge: Intel Corporation Device 9d14 (rev f1) > 00:1d.0 PCI bridge: Intel Corporation Device 9d18 (rev f1) > 00:1e.0 Signal processing controller: Intel Corporation Device 9d27 > (rev 21) > 00:1e.6 SD Host controller: Intel Corporation Device 9d2d (rev 21) > 00:1f.0 ISA bridge: Intel Corporation Device 9d48 (rev 21) > 00:1f.2 Memory controller: Intel Corporation Device 9d21 (rev 21) > 00:1f.3 Audio device: Intel Corporation Device 9d70 (rev 21) > 00:1f.4 SMBus: Intel Corporation Device 9d23 (rev 21) > 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection I219- > V (rev 21) 01:00.0 Network controller: Intel Corporation Wireless > 8260 (rev 3a) 02:00.0 Non-Volatile memory controller: Samsung > Electronics Co Ltd Device a802 (rev 01) /sys/kernel/iommu_groups/7 > /sys/kernel/iommu_groups/7/devices > /sys/kernel/iommu_groups/7/devices/0000:00:1f.0 > /sys/kernel/iommu_groups/7/devices/0000:00:1f.2 > /sys/kernel/iommu_groups/7/devices/0000:00:1f.3 > /sys/kernel/iommu_groups/7/devices/0000:00:1f.4 > /sys/kernel/iommu_groups/7/devices/0000:00:1f.6 > > > _________________________________________________ > vfio-users mailing list [email protected] > https://www.redhat.com/mailman/listinfo/vfio-users
