Does intel atom support hot plug of PCI devices ?
If so, is there a documentation that describes the feature ?
we would keep out of reset an FPGA after system boot. That FPGA will be passed to a Linux Container, we would receive the hotplug notification for this event.
Unfortunately PCI Express Hot-Plug events are not supported by the Intel Atom Processor C2508.
Please review this Document, (Doc number 51024) , http://www.intel.com/content/www/us/en/secure/intelligent-systems/privileged/rangeley/soc-external-d... Intel Atom Processor C2000 Product Family for Communications Infrastructure, External Design Specification (EDS), on section 12.2 page 247 " The Hardware-based and card-detect PCIe Hot-Plug is not a supported feature".
In the same document, section 12.5.1 page 258, "The SoC PCI Express * Root Ports do not support the hot-add and hot-removal of PCI Express adapters. The PCIe specification calls this PCI Express Hot-Plug* support. The root ports also do not support the detection of an adapter that has been newly plugged-in (connected) or newly powered-on".
If there is any other question or comment please let us know.
