CONFIG_AMD_PTDMA: AMD PassThru DMA Engine

General informations

The Linux kernel configuration item CONFIG_AMD_PTDMA has multiple definitions:

AMD PassThru DMA Engine found in drivers/dma/amd/Kconfig

The configuration item CONFIG_AMD_PTDMA:

• prompt: AMD PassThru DMA Engine
• type: tristate
• depends on: CONFIG_X86_64 && CONFIG_PCI
• defined in drivers/dma/amd/Kconfig
• found in Linux kernels: 6.14, 6.15-rc+HEAD
• modules built: ptdma, ptdma

Help text

Enable support for the AMD PTDMA controller. This controller provides DMA capabilities to perform high bandwidth memory to memory and IO copy operations. It performs DMA transfer through queue-based descriptor management. This DMA controller is intended to be used with AMD Non-Transparent Bridge devices and not for general purpose peripheral DMA.
