Nein, es ist ein Standard ubuntu 14.04 LTS, Kernel 3.13.0-71-generic. Xeon E3-1240 auf einem Asus P8B WS (PCH C206). Ich habe auf die Schnelle nur die GT218 in den dritten Slot gesteckt, daß ist der PCIe Slot der mit x4 direkt an der CPU hängt. Die primäre GTX 960 hängt mit x16 ebenfalls an der CPU. Ich könnte noch ausprobieren die GT218 in den untersten Slot (x4 am PCH) zu stecken. In den zweiten paßt sie nicht, weil sie sich mit der GTX 960 in die Quere kommt. Dazu müßte ich die Karten umbauen, und dazu habe ich gerade keine Lust. Ich habe das Thema VT-d nicht weiterverfolgt, weil ich die GTX 960 als Karte für Linux weiternutzen will, und für die Gäste eine UEFI Karte bräuchte. Sprich die GT218 kommt dazu leider nicht in Frage.jdl: hm, das ist interessant- wie sehen denn die IOMMU-Gruppen aus (und das ACS-Patch hast du nicht installiert)?

Wenn ich die Doku der verschiedenen Xeon E3 Generation richtig interpretiere, hat bis auf den Xeon E3v5 jede der Generationen die zwei PCI root Devices mit ID 1 und 6. Der E3v5 hat nur noch ID 1. Die 16+4 Lanes gab es bei Xeon E3 und E3v2. Der E3v2 hat 16 3.0 der ältere nur 16 2.0 Lanes. Am Wochenende werde ich die Grafikkarte doch nochmals umbauen. Die GT218 wird im PCH Slot auf PCIe 03:00.0 und 03:00.1 gemappt und der IOMMU Gruppe 6 zugeteilt. Sprich alle PCIe Ports des PCHs sind in einer IOMMU Gruppe.danke, da hat der CPU-Port gleich 2 Root-Hubs– mit den neueren C-Chipsätzen scheint das nicht mehr zu gehen, die haben aber auch nur noch 16 Lanes, DANKE Intel -.-.

Without ACS, it is possible for a PCIe Endpoint to either accidentally or intentionally (maliciously) write to an invalid/illegal area on a peer endpoint, potentially causing problems.
