Hi, Our driver mmaps the kernel buffer and setup a DMA when the mmapped buffer is filled with the data.
How will the driver know whether the user space has filled the buffer with the data? Can the application use msync to notify the driver with the starting address and the size of the data as documented in msync? What is the file operation that the driver should implement for msync if it is allowed? I appreciate your help.
