Enable support for the Qualcomm Technologies HIDMA Management.
|
|
Each DMA device requires one management interface driver
|
|
for basic initialization before QCOM_HIDMA channel driver can
|
|
start managing the channels. In a virtualized environment,
|
|
the guest OS would run QCOM_HIDMA channel driver and the
|
|
host would run the QCOM_HIDMA_MGMT management driver.

Enable support for the Qualcomm Technologies HIDMA controller.
|
|
The HIDMA controller supports optimized buffer copies
|
|
(user to kernel, kernel to kernel, etc.). It only supports
|
|
memcpy interface. The core is not intended for general
|
|
purpose slave DMA.

Enable support for the QCOM GPI DMA controller. This controller
|
|
provides DMA capabilities for a variety of peripheral buses such
|
|
as I2C, UART, and SPI. By using GPI dmaengine driver, bus drivers
|
|
can use a standardize interface that is protocol independent to
|
|
transfer data between DDR and peripheral.

PCIe controller that provides DMA capabilities for clients.

Enable detailed logging for QCOM PCIe eDMA driver. Should

only be enabled for debugging purpose since excessive logging
|
|
of all channels information and activity will decrease throughput.
