The problem is with my arm zynq remoteproc driver where I use dma_declare_coherent_memory() to specify memory for remoteproc which is ioremap to the vmalloc area. Based on that buf addr is not inside ram even this coherent memory is in = ram. That's why virt_addr_valid(buf) is failing. Thanks for you input, Michal --=20 Michal Simek, Ing.
