Message-ID: <912ec82a1002230847h11d0f628rbd38b12f38270735@mail.gmail.com> Date: Tue, 23 Feb 2010 18:47:34 +0200 From: Neshama Parhoti <pneshama@...il.com> To: linux-kernel@...r.kernel.org Subject: sysfs vs. ioctl hi all, we are in the process of writing a new driver and we don't know whether to choose a sysfs or ioctl interface to user space. we know that sysfs is preferred, but we're concerned it will have bad performance when compared to ioctl (our driver will have its interface might be used many dozens of times per second, possible even more than 100 times per second). so should we opt for ioctls if a usage is expected even every 5 miliseconds (in extreme scenarios) ? thank you in advance for the help ~pnesh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
