Subject[PATCH v6 0/4] PCI: Patch series to support Thunderbolt without any BIOS support
Date
Rebase patches to apply cleanly to 5.2-rc1 source. Remove patch for 
comment style cleanup as this has already been applied.

Anybody interested in testing, you can do so with:

a) Intel system with Thunderbolt 3 and native enumeration. The Gigabyte
Z390 Designare is one of the most perfect for this that I have never had
the opportunity to use - it does not even have the option for BIOS
assisted enumeration present in the BIOS.

b) Any system with PCIe and the Gigabyte GC-TITAN RIDGE add-in card,
jump the header as described and use kernel parameters like:

pci=assign-busses,hpbussize=0x33,realloc,hpmemsize=128M,hpmemprefsize=1G,nocrs
pcie_ports=native

[optional] pci.dyndbg

The Intel system is nice in that it should just work. The add-in card
setup is nice in that you can go nuts and assign copious amounts of
MMIO_PREF - can anybody show a Xeon Phi coprocessor with 16G BAR working
in an eGPU enclosure with these patches?

However, if you specify the above kernel parameters on the Intel system,
you should be able to override it to allocate more space.

Nicholas Johnson (4):
PCI: Consider alignment of hot-added bridges when distributing
available resources
PCI: Modify extend_bridge_window() to set resource size directly
PCI: Fix bug resulting in double hpmemsize being assigned to MMIO
window
PCI: Add pci=hpmemprefsize parameter to set MMIO_PREF size
independently
