[Qemu-arm] [RFC PATCH 6/7] misc: CCIX endpoint function |
Date: |
Tue, 25 Jun 2019 19:27:51 +0800 |
This handles the case where a given function is not also a
PCIe topology upstream or downstream port.
This include, non function 0 functions on upstream ports and
any function on a device without a PCIe switch. Note that
this doesn't exclude the possibility of this being the upstream
port of a CCIX layer switch.
