I just noticed when setting up MSI support that ib_mthca fails with the following:
This is on 2 different Intel platforms that worked with OFED 1.2: ib_mthca: Mellanox InfiniBand HCA driver v0.08 (February 14, 2006) ib_mthca: Initializing 0000:0a:00.0 ACPI: PCI interrupt 0000:0a:00.0[A] -> GSI 16 (level, low) -> IRQ 169 PCI: Setting latency timer of device 0000:0a:00.0 to 64 ib_mthca 0000:0a:00.0: NOP command failed to generate interrupt (IRQ 233), aborting. ib_mthca 0000:0a:00.0: Try again with MSI/MSI-X disabled. ib_mthca: probe of 0000:0a:00.0 failed with error -16 lspci -v v 0a:00.0 InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex (Tavor compatibility mode) (rev a0) Subsystem: Mellanox Technologies MT25208 InfiniHost III Ex (Tavor compatibility mode) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0, Cache Line Size 10 Interrupt: pin A routed to IRQ 169 Region 0: Memory at c1300000 (64-bit, non-prefetchable) [size=1M] Region 2: Memory at c0000000 (64-bit, prefetchable) [size=8M] Region 4: Memory at b8000000 (64-bit, prefetchable) [size=128M] Capabilities: [40] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [48] Vital Product Data Capabilities: [90] Message Signalled Interrupts: 64bit+ Queue=0/5 Enable- Address: 0000000000007000 Data: 0000 Capabilities: [84] MSI-X: Enable- Mask- TabSize=32 Vector table: BAR=0 offset=00082000 PBA: BAR=0 offset=00082200 Capabilities: [60] Express Endpoint IRQ 0 Device: Supported: MaxPayload 128 bytes, PhantFunc 0, ExtTag- Device: Latency L0s <64ns, L1 unlimited Device: AtnBtn- AtnInd- PwrInd- Device: Errors: Correctable+ Non-Fatal+ Fatal+ Unsupported- Device: RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop- Device: MaxPayload 128 bytes, MaxReadReq 512 bytes Link: Supported Speed 2.5Gb/s, Width x8, ASPM L0s, Port 8 Link: Latency L0s unlimited, L1 unlimited Link: ASPM Disabled RCB 64 bytes CommClk- ExtSynch- Link: Speed 2.5Gb/s, Width x8 /etc/modprobe.conf options ib_mthca msi=1 Anyone else see this issue? -arlin _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
