Hi all, I am using rmb, wmb and mb() calls through driver when accessing BAR regions of memory-mapped PCIe device. It is possible to mmap these BAR regions to user space. I am calling mmap from user application to map the BAR regions. After successful return of mmap, we have start address of BAR region using which we can access the device directly. Now I need to assure ordering between read or write operations. How to achieve this ? Any functions similar to rmb, wmb or mb at user level available ? Kindly, correct me if i am missing something. Any info/link/reference will be of great help. Thanks in advance.
