RUS Sergei Miroshnichenko: Setting up the PCIe hotplug in Kernel for flexible setups, , Linux Piter

Setting up the PCIe hotplug in Kernel for flexible setups It is relatively easy to tune the current Linux kernel via command line arguments to handle hotadded PCI devices if the expected topology is known and limited: just reserve enough address space and bus numbers per a hotplug slot, so new devices can fit there. But if the system demands online, substantial and frequent reshaping of a current topology, the constrained nature of the PCIe applies severe restrictions on that. In this presentation, we de
