x86: PCI Express Support on x86 Systems
This device management feature is new in the Solaris Express 1/06 release.
This Solaris release provides support for the PCI Express (PCIe) interconnect. PCIe is designed to connect peripheral devices to desktop, enterprise, mobile, communication, and embedded applications.
The PCIe interconnect is an industry-standard, high-performance, serial I/O bus. For details on PCIe technology, go to the following site:
The PCIe software provides the following features in this Solaris release:
-
Support for extended PCIe configuration space
-
Support for PCIe baseline error handling and MSI interrupts
-
Modified IEEE-1275 properties for PCIe devices
-
PCIe hotplug support (both native and ACPI-based) by enhancing the cfgadm_pci component of the cfgadm command
-
ATTN Button usage-based PCIe peripheral autoconfiguration
The following cfgadm example output displays the hotpluggable PCIe devices on an x86 system. Note that the display below may differ from platform to platform. Check your hardware platform guide for the correct cfgadm syntax.
# cfgadm pci Ap_Id Type Receptacle Occupant Condition pcie1 unknown empty unconfigured unknown pcie2 unknown empty unconfigured unknown pcie3 unknown empty unconfigured unknown pcie4 etherne/hp connected configured ok pcie5 pci-pci/hp connected configured ok pcie6 unknown disconnected unconfigured unknown |
The administrative model for hotplugging PCIe peripherals is the same as for PCI peripherals, which uses the cfgadm command.
For more information, see the cfgadm_pci(1M) man page and the System Administration Guide: Devices and File Systems. Check your hardware platform guide to ensure that PCIe and PCIe hotplug support is provided on your system. In addition, carefully review the instructions for physically inserting or removing adapters on your system. And, review the semantics of device auto-configuration, if applicable.
