As one of the leading cloud computing companies, Microsoft uses AMD’s data center GPUs as well as Linux on the servers it uses. Sometimes those GPUs need to be installed into running machines or replaced, but that requires shutting down the server and then swapping out the GPU. To enable flawless hot-plug replacements, which means the GPU can be pulled out of the PCIe slot and replaced while the computer is still running, Microsoft has developed a special driver that enables hot-plugging AMD GPUs on Linux servers.
