10GigEthr-03 (iocxgbe) B.11.31.1203 Ethernet Driver Release Notes, Edition 2

New and changed features in this release
New features
The following features are new with this version of 10GigEthr-03:
• Direct I/O (DIO) support
Direct IO networking gives the LAN device driver direct control of the device's IO. This
minimizes device emulation overhead that would be incurred with accelerated virtual I/O
(AVIO). In HP-UX vPars and Integrity VM environments, AVIO I/O devices are para-virtualized
and do not allow the guest operating system to directly control the hardware. With direct I/O,
the LAN device driver runs on the guest and directly controls devices that have no emulation.
As such, direct I/O performs better than AVIO.
NOTE: Because DIO functionality has not been tested with the AT094A adapter, HP does
not support DIO with this particular adapter.
• PCI error handling and recovery
Peripheral Component Interconnect (PCI) failures account for a significant percentage of errors
in computer systems. The PCI Error Recovery (PCI ER) feature enables:
◦ Detection of PCI bus parity errors
◦ Isolation of the failed I/O path
◦ Automatic recovery of cards from errors
With this feature enabled (by default), if an error occurs on a PCI bus containing an I/O card
that supports PCI Error Recovery:
◦ The PCI bus is quarantined to isolate the system from I/O and prevent harm to the system.
◦ PCI ER attempts to recover from the error and to reinitialize the bus so that I/O can resume.
The PCI ER feature avoids system crashes, decreases system downtime, and supports
single-system high availability. For more information about PCI error handling and recovery,
see the PCI/PCIe Error Recovery Product Note at:
