Hello Everyone, I need a around 2GB of physically contiguous memory in Linux. I am using vanilla kernel 4.3 in Fedroa22. I am aware about the function alloc_contig_range and that function should be used through DMA. In DMA what is the exact API to be used and I have enabled CONFIG_CMA and CONFIG_CMA_DMA . In kernel coomand line parameters what is the exact stuff to be given. The documentation is not proper for the kernel parameters in the documentation provided in the source code. Is there any other way to allocate large chunk of memory that is contiguous.
Thanking You, Kumar.
