PCIe adapters on POWER8® that take advantage of 64-bit DMA

Peripheral Component Interconnect Express (PCIe) adapters that are supported for POWER8 systems vary in their ability to take advantage of 64-bit DMA with Linux.

IBM® POWER8 systems that are running Linux support various PCIe adapters, depending on the system. And each of those adapters differs in whether it is 64-bit DMA capable.

This topic addresses the supported adapters for IBM POWER8 systems only. IBM POWER8 systems include the following machine types and models:

8247-21L
8247-22L
8247-42L
8284-22A
8286-41A
8286-42A
9119-MHE
9119-MME

The following table lists PCIe adapters and descriptions that are supported for Linux running on POWER8 systems, which are listed by machine type and model. In addition, the table indicates for each adapter whether placing the adapter in a 64-bit DMA-capable slot provides any performance benefit.

For instructions for how to install PCIe adapters on POWER8 systems, see the following topics:

For details about which slots are 64-bit DMA capable, see the following topics in the IBM POWER8 information:

The table that follows gives recommendations. The following list provides detail on the recommendations.

No benefit: The adapter or driver does not recognize the capability, or the adapter is not a high performance adapter. For example, a modem.
Optional; possible benefit: The adapter or driver recognizes the capability and enables it. Depending on workload, your system might or might not see a performance benefit when the adapter is placed in a 64-bit DMA capable slot.
Recommended; likely benefit: The adapter or driver recognizes the capability and enables it. Depending on your workload, your system likely will have improved efficiency and performance when the adapter is placed in a 64-bit DMA capable slot.
Highly recommended: The adapter or driver recognizes the capability and enables it. Your system should have improved efficiency and performance when the adapter is placed in a 64-bit DMA capable slot.
Required: The adapter must be placed in a 64-bit DMA capable slot, or functional issues might occur.
