I am porting 3114 driver to RTOS but have problems in using BAR5 PCI config space because of Memory mapped region issues. I can access BAR4 and plan to set up DMA mode. How do we access entire BAR5 memory space without using BAR5, is there any indirect way to access BAR5 using BAR4. Please let me know.
