| |
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()
