CONFIG_PCIE_TANGO_SMP8759: Tango SMP8759 PCIe controller (DANGEROUS)

General informations

The Linux kernel configuration item CONFIG_PCIE_TANGO_SMP8759 has multiple definitions:

Tango SMP8759 PCIe controller (DANGEROUS) found in drivers/pci/controller/Kconfig

The configuration item CONFIG_PCIE_TANGO_SMP8759:

• prompt: Tango SMP8759 PCIe controller (DANGEROUS)
• type: bool
• depends on: ( CONFIG_ARCH_TANGO && CONFIG_PCI_MSI && CONFIG_OF ) && ( CONFIG_BROKEN )
• defined in drivers/pci/controller/Kconfig
• found in Linux kernels: 4.18–4.20, 5.0–5.11

Help text

Say Y here to enable PCIe controller support for Sigma Designs Tango SMP8759-based systems.

Note: The SMP8759 controller multiplexes PCI config and MMIO accesses, and Linux doesn't provide a way to serialize them. This can lead to data corruption if drivers perform concurrent config and MMIO accesses.
