This chapter discusses the advanced and optional features of PCI, including interrupt handling, the "Special" cycle command and 64-bit extensions. The Special cycle provides a mechanism to broadcast information to multiple targets simultaneously. The specification suggests that it is a useful way to ...
Conserve valuable PCI Express (PCIe*) server slots while adding four ports of Gigabit Ethernet capability with the Intel® Gigabit VT Quad Port Server Adapter. The dedicated input/output (I/O) bandwidth of PCIe ensures priority performance on each port—without bus sharing—for Gigabit Ethernet ...
User packet interface with a split-bus architecture where the header, data and prefix busses consist of four segments each (x16 mode only). Up to 768 outstanding Non-Posted requests (x16 core only). Up to 512 outstanding Non-Posted requests (x8 and x4 cores). Summary of outstanding Non...
[ConnectX-4 and above] Added support for single IRQ for PCI function. To use a high number of VFs, a large amount of IRQs is required which the device cannot always support. This feature enables VFs to function with a minimum of a single IRQ instead of two. This is done via dynamic...

PCI Express 2.0 and 3.0 Support Designed for the PCI Express 3.0 bus architecture offering the highest data transfer speeds for the most bandwidth-hungry games and 3d applications, while maintaining backwards compatibility with existing PCI Express motherboards for the broadest support. ...
The new interface names look as follows: en[P][p<bus number]sf For example, a ConnectX device with PCI address: 0005:01:00.1 will be named enP5p1s0f1 The advantage of such a scheme for interface naming is that device whose PCI address is 0005:01:00.1 will always get the same device...
From following the mainline Linux development for the H6, it looks like the PCI-E is broken on them and will stay that way. Short of any likely performance killing hack or dedicated drivers, it will never have general purpose PCI-E. So, I wouldn’t count PCI-E among the H6’s benefit...
GPU Upload Heaps provides a fast and convenient way to copy data from the CPU to the GPU in certain scenarios. Without this feature, GPU VRAM has traditionally been inaccessible to the CPU and all copies must go through the PCI bus. However, most modern GPUs have a resizable BAR (Base Ad...
PCI Express prompts QUIET EVOLUTION The article focuses on the evolution of the Peripheral Component Interconnect (PCI) bus to the serial PCI Express (PCIe). It is noted that the PCI has evolved higher speeds and wider buses to boost system performance, but problems with t... RA Quinnell -...
