当初为了开发usb总线驱动,还重新构建了基于wdm模型的总线驱动框架代码,其实主要是处理 IRP_MJ_PNP, IRP_MJ_POWER命令, 别看只有两个命令,其实处理的内容非常多,还得考虑如何管理PDO等内容。 自己实现的这个框架代码,目前用在了 USB虚拟主机控制器的开发上(以前的文章阐述过usb虚拟总线的开发,有兴趣可去查阅), 也...
指向微型端口驱动程序的每适配器非分页存储区域的指针。 操作系统特定的端口驱动程序在调用微型端口的VIRTUAL_HW_FIND_ADAPTER例程之前,会为该扩展分配内存,并使用零初始化此扩展。 HwContext 指向设备堆栈中 PDO 的指针。 HBA 本身就是 FDO。 如果微型端口驱动程序控制物理硬件,则 PDO 可能属于 Pci.sys 驱动程序。
Participatory Design Approach (PDO) is a design methodology that involves users in the design process from the beginning as co-designers throughout the design process (Van der Velden and Mörtberg 2015; Cumbo and Selwyn 2022). According to Johnson (1998), PDA is frequently acknowledged as a...
請注意,這應該會傳回值和副作用,就像寫入虛擬設備的設定區塊一樣。 使用這個介面可以透過在提供介面的驅動程式內部處理它,或從較低層級 PDO) 或兩者組合的PCI_VIRTUALIZATION_INTERFACE呼叫SetVirtualFunctionData(,來完成寫入。 規格需求 需求值 標頭dispmprt.h ...
