menuconfig USB4 tristate "Unified support for USB4 and Thunderbolt" depends on PCI select APPLE_PROPERTIES if EFI_STUB && X86 select CRC32 select CRYPTO select CRYPTO_HASH select NVMEM help USB4 and Thunderbolt driver. USB4 is the public specification based on the Thunderbolt 3 protocol. This driver is required if you want to hotplug Thunderbolt and USB4 compliant devices on Apple hardware or on PCs with Intel Falcon Ridge or newer.

  To compile this driver a module, choose M here. The module will be
  called thunderbolt.

if USB4

config USB4_DEBUGFS_WRITE bool "Enable write by debugfs to configuration spaces (DANGEROUS)" help Enables writing to device configuration registers through debugfs interface.

  Only enable this if you know what you are doing! Never enable
  this for production systems or distro kernels.

config USB4_DEBUGFS_MARGINING bool "Expose receiver lane margining operations under USB4 ports (DANGEROUS)" depends on DEBUG_FS depends on USB4_DEBUGFS_WRITE help Enables hardware and software based receiver lane margining support under each USB4 port. Used for electrical quality and robustness validation during manufacturing. Should not be enabled by distro kernels.

config USB4_KUNIT_TEST bool "KUnit tests" if !KUNIT_ALL_TESTS depends on USB4 && KUNIT=y default KUNIT_ALL_TESTS

config USB4_DMA_TEST tristate "DMA traffic test driver" depends on DEBUG_FS help This allows sending and receiving DMA traffic through loopback connection. Loopback connection can be done by either special dongle that has TX/RX lines crossed, or by simply connecting a cable back to the host. Only enable this if you know what you are doing. Normal users and distro kernels should say N here.

  To compile this driver a module, choose M here. The module will be
  called thunderbolt_dma_test.
