pciem

PCIem 一个 Linux 内核框架，支持合成用户空间 PCIe 设备模拟。 | 文档 PCIem 是什么？ PCIem 是一个框架，通过利用一些新颖技术，在 Linux 内核中创建虚拟 PCIe 设备，将合成卡作为合法的 PCI 设备呈现给主机操作系统。 简而言之，PCIem 是一个用于（但不限于）开发和测试 PCIe 设备驱动程序的框架，无需主机上的实际硬件。 与 libfvio-user 的比较 PCIem 和 libfvio-user 是两种针对不同需求的解决方案，比较两者时可能会产生混淆，因此此处说明差异（更多信息请参见图1）。 主要区别在于，libvfio-user...
