The wrong values are reported from pcie_bandwidth_available() which
can cause problems for performance of eGPUs.
This series overhauls Thunderbolt related device detection and uses
the changes to change the behavior of pcie_bandwidth_available().
v2->v3:
* Stop lumping all thunderbolt VSEC and USB4 devices together, introduce
is_virtual_link instead
* Drop unnecessary patches
Mario Limonciello (7):
drm/nouveau: Switch from pci_is_thunderbolt_attached() to
dev_is_removable()
drm/radeon: Switch from pci_is_thunderbolt_attached() to
dev_is_removable()
PCI: Drop pci_is_thunderbolt_attached()
PCI: pciehp: Move check for is_thunderbolt into a quirk
PCI: ACPI: Detect PCIe root ports that are used for tunneling
PCI: Split up some logic in pcie_bandwidth_available() to separate
function
PCI: Exclude PCIe ports used for virtual links in
pcie_bandwidth_available()
