I am creating a driver for a FPGA connecting by PCI. I want to alloc a dma memory using dma_alloc_coherent and pci_alloc_consistent. However I got the next error:

 pci 0002:01:00.0:  dma_direct_alloc_coherent: No suitable zone for pfn 0x7f000 

I am using kernel 4.1 (SDK 2.0). In the previous version worked properly. Any idea how to solve it?
