CONFIG_PCIE_TEGRA194_EP: NVIDIA Tegra194 (and later) PCIe controller (endpoint mode)

General informations

The Linux kernel configuration item CONFIG_PCIE_TEGRA194_EP has multiple definitions:

NVIDIA Tegra194 (and later) PCIe controller (endpoint mode) found in drivers/pci/controller/dwc/Kconfig

The configuration item CONFIG_PCIE_TEGRA194_EP:

• prompt: NVIDIA Tegra194 (and later) PCIe controller (endpoint mode)
• type: tristate
• depends on: ( CONFIG_ARCH_TEGRA_194_SOC || CONFIG_COMPILE_TEST ) && ( CONFIG_PCI_ENDPOINT )
• defined in drivers/pci/controller/dwc/Kconfig
• found in Linux kernels: 6.4–6.12, 6.13-rc+HEAD

Help text

Enables support for the PCIe controller in the NVIDIA Tegra194 SoC to work in endpoint mode. There are two instances of PCIe controllers in Tegra194. This controller can work either as EP or RC. In order to enable host-specific features PCIE_TEGRA194_HOST must be selected and in order to enable device-specific features PCIE_TEGRA194_EP must be selected. This uses the DesignWare core.
