Hi Marek, Thanks for the patch. On Monday 20 August 2012 11:46 AM, Marek Szyprowski wrote:
Contiguous Memory Allocator requires only paging and MMU enabled not particular CPU architectures, so there is no need for strict dependency on CPU type. This enables to use CMA on some older ARM v5 systems which also might need large contiguous blocks for the multimedia processing hw modules. Reported-by: Prabhakar Lad <prabhakar.csengg@gmail.com>
