Hi, I noticed recently that we're missing the compat IOCTL handling in Media controller API to support 32-bit binaries on 64-bit systems. I guess the issue hasn't bitten anyone too badly since this hasn't been noticed earlier. I can think of the reasons, too: Media controller is primarily used on embedded systems that are still mainly 32-bit and the binaries are targeted to those very systems specifically. I noticed this since I'm currently running my 32-bit Debian system on a 64-bit kernel (I like to run 64-bit virtual machines but I'm lazy to update; waiting for multiarch) so my native media-ctl binary just failed to report anything about a UVC device Laurent kindly lended me. The patchset implements separate compat ioctl handling and splits link enumeration handling into 32-bit and 64-bit portions. Many thanks to Laurent for testing these patches! -- Kind regards, Sakari Ailus sakari.ailus@xxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
