1.INTx 中断是相对古老的PCIe设备中断方式,整个系统仅支持8个INTx 中断,所有设备共用。PCIe 中的INTx 中断是通过PCIe message发送到 switch 和 IO APIC的。CPU收到 IO APIC 转发到 local APIC 的 INTx 中断后,需要查询ISR确定中断源设备,并进一步查询中断含义,才能执行中断处理函数。中断数量少,中断查询复杂,响...

PCIe在Linux driver中被抽象为各种数据结构,PCIe Host bridge被抽象为struct pci_host_bridge;PCIe bus被抽象为struct pci_bus; PCIe switch 和PCIe endpoint被抽象为struct pci_dev. PCIe 配置空间 PCIe配置空间分为兼容配置空间和扩展配置空间。 兼容配置空间: PCIe配置空间完整保留了PCI总线的配置空间,大小256Byte...
A Linux kernel device driver for the PCIe endpoint controller. This driver configures the PCIe controller as an endpoint, and provides an interface for higher-level software to select the configuration that is exposed to the PCIe bus. The source code for this driver is available at the following...

Altera does not provide the Windows source code for the PCIe driver. The reference design and Linux source can be found from related links in the AN690: https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an690.pdf There is an ...
所编写的驱动代码程序包括7个源代码文件,分别是Device.h, Driver.h, Public.h, Trace.h, Device.c,Driver.c, Queue.c。其中Device.h 定义了与硬件相关的地址偏移;Public.h定义了DeviceIoControl 用到的用户自定义命令字, 此头文件由上层应用程序和驱动程序共同使用;Queue.c定义了I/O回调例程,分别使用了read、...
