In a virtualized environment, 18 the guest OS would run QCOM_HIDMA channel driver and the 19 host would run the QCOM_HIDMA_MGMT management driver. 20 21config QCOM_HIDMA 22 tristate "Qualcomm Technologies HIDMA Channel support" 23 select DMA_ENGINE 24 help 25 Enable support for the Qualcomm Technologies HIDMA controller. 26 The HIDMA controller supports optimized buffer copies 27 (user to kernel, kernel to kernel, etc.). It only supports 28 memcpy interface. The core is not intended for general 29 purpose slave DMA. 30
