The gasket in-kernel framework, recently introduced under staging, re-implements what is already long-time provided by the UIO subsystem, with extra PCI BAR remapping and MSI conveniences. Before moving it out of staging, make sure we add the new bits to the UIO framework instead, then transform its signle client, the Apex driver, to a proper UIO driver (uio_driver.h).

The driver core should handle all of this for you automaically. There should not be a need for raw attribute macros. -- Darwi http://darwish.chasingpointers.com _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
