PCI Peer-to-Peer DMA Support — The Linux Kernel documentation

WebWhen you call the funtion "pci_ioremap_bar (pdev, 2)", the function needs some resource data to remap the memory space. For example, [2] = { .name = "ep_mem2", .start = … WebDescription. Tell if a device supports a given HyperTransport capability. Returns an address within the device’s PCI configuration space or 0 in case the device does not support the request capability. The address points to the PCI capability, of type PCI_CAP_ID_HT, which has a HyperTransport capability matching ht_cap. flatbed dump truck body

WebIntroduction — The Linux Kernel documentation. This document is a guide to use the PCI Endpoint Framework in order to create endpoint controller driver, endpoint function … Web10 jan. 2007 · 1. Intro devres came up while trying to convert libata to use iomap. Each iomapped address should be kept and unmapped on driver detach. For example, a plain SFF ATA controller (that is, good old PCI IDE) in native mode makes use of 5 PCI BARs and all of them should be maintained.
