Sure. Use something like "lspci -vvvnn" and check out LnkCap and LnkSta under Capabilities. There you can see both the number of channels and symbol rate. For example for an x8 card in an x4 slot (connection-wise - the connector is of course wider or the x8 card wouldn't fit): LnkCap: Port #0, Speed 5GT/s, Width x8, ASPM L0s, Exit Latency L0s <512ns, L1 <4us LnkSta: Speed 2.5GT/s, Width x4, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- Bjørn _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
