Hi All, I am trying to understand if there is support for hotplugging of IVSHMEM devices in dpdk. I set up a simple experiment where I hotplugged an ivshmem device into a VM using the device_add command plus the command line generated by rte_ivshmem_metadata_cmdline_generate in QEMU monitor. It appears to work, in fact, when I run lspci in the guest I can see the device, but when I execute a simple dpdk application that looks for a ring that was previously mapped into the device, it's not able to find it. In fact when the application starts, the EAL appears not to find the device.
So my question is the following: is there support for IVSHMEM hotplug in the current dpdk implementation? I used the last dpdk version available in git, a host with a kernel 3.13.0-43 and a guest with 3.12.0-rc1. Thank you very much. Mauricio V,
