13e99bc0b9 hv: vPCI: passthrough MSI-X Control Register to guest.
In spite of Table Size in MSI-X Message Control Register [Bits 10:0] masks as
RO (Register bits are read-only and cannot be altered by software), In Spec
PCIe 6.0, Chap 6.1.4.2 MSI-X Configuration "Depending upon system software
policy, system software, device driver software, or each at different times or
environments may configure a Function’s MSI-X Capability and table structures

8b16be9185 Remove "All rights reserved" string headers
Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.

bd92304dcf HV: add vpci bridge operations support
add vpci bridge operations in hypervisor, to avoid SOS mis-operations
to affect other VM's PCI devices.

assumption: before hypervisor bootup, the physical pci-bridge shall be
configured correctly by BIOS or other bootloader; for ACS (Access
Control Service) capability, it is configured by BIOS to support the
devices under it to be isolated and allocated to different VMs.

to simplify the emulations of vpci bridge, set limitations as following:
  1. expose all configure space registers, but readonly
  2. BIST not support; by default is 0
  3. not support interrupt, including INTx and MSI.

TODO:
  1. configure tool can select whether a PCI bridge is emulated or pass
  through.

Open:
  1. SOS how to reset PCI device under the PCI bridge?
