Hello, I am looking for some help. I am using ivshmem-v2 with virtio. I am planning to implement a virtual serial driver on top of it. I ripped off the ivshmem-net driver, and obtain a queue which I should able to communicate with other cells from host.
The problem is that during root cell's PCI probing, pci_alloc_irq_vectors returned -NOSPCE. I went down the rabbit hole with ftrace and found out that in the MSIX initialization, irq_find_mapping returned -EEXIST. I have cross check the code with ivshmem-net, there is no difference except for the NAPI registration. I am filling quite helpless down this rabbithole, and can really use some help. I can provide the trace log and driver code if it is necessary. Thanks, Yang -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
