- CONFIG_DUMMY_DMA¶
Dummy DMA (software DMA driver)
Type: bool
Help¶
Select this to enable the software-based host DMA implementation.
This driver does all the transfers between host memory and DSP local
buffer memory using regular memcpy. It requires direct access to the
host memory.
If unsure, select "n".
Direct dependencies¶
HOST_PTABLE && SOF
(Includes any dependencies from ifs and menus.)
Default¶
n
