内核模块注册kvm_ivshmem这个字符设备之后,通过pci_register_driver(&kvm_ivshmem_pci_driver)实现字符型pci设备注册,随后由pci_driver数据结构中的probe函数指针所指向的侦测函数来初始化该PCI设备: staticint kvm_ivshmem_probe_device (struct pci_dev *pdev, conststruct pci_device_id * ent) { int result; pr...
ivshmem PCI设备中断机制驱动示例 之前的文章<<QEMU虚拟机内识别ivshmem设备>>介绍了在虚拟机内通过用户态程序访问ivshmem设备的共享内存。在虚拟机之间或者宿主机与虚拟机之间通过共享内存进行通信的情形下,共享内存的两端必须依赖轮询方式来实现通知机制。这种方式是ivshmem提供的ivshmem-plain的使用方式。除此之外,ivshmem...

I can add a case to test ivshmem device discovery but can't test the device function since our test kernel doesn't have a driver for ivshmem. So I'm not sure if we need to add this test case. Is there a plan to upstream the said driver? I think a very basic test case will be...

This is a simple demo for creating a virtio-over-ivshmem backend driver for a virtio console. TODO: - resolve hacks - extract common bits to be shared with similar backends. Note: Specification work for virtio-over-ivshmem is ongoing, so details may still change. Signed-off-by: Jan Kiszka...
