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

From: Sui Jingfeng <suijingfeng at loongson.cn> Currently, the default VGA device selection is not perfect. Potential problems are: 1) This function is a no-op on non-x86 architectures. 2) It does not take the PCI Bar may get relocated into consideration. 3) It is not effective for the PCI device without a dedicated VRAM Bar. 4) It is device-agnostic, thus it has to waste the effort to

From: Sui Jingfeng <suijingfeng at loongson.cn> On a machine with multiple GPUs, a Linux user has no control over which one is primary at boot time. This series tries to solve above mentioned problem by introduced the ->be_primary() function stub. The specific device drivers can provide an implementation to hook up with this stub by calling the vga_client_register() function. Once the
