Description
Certain PCIe features aren't handled well in Linux, for instance, hotplug doesn't seem to care about MRL status. There are other implications on features as the following:
- MPS/MRRS
- 10b, 14b tag support
Both need to be enabled to the entire path from the root port to the device. If a new device is hotplugged, how are MPS, 10b tag enabled throughout the path?
Linux lacks support for Flattening Portal Bridge (FPB) to improve ability to manage resources in a more structured way.
