Hi, I am using this on x86 machine..so no device tree...where do I have to register elsewhere here.? On 15 Apr 2016 2:15 p.m., "anish singh" <anish198519851985@gmail.com> wrote:

Dear all,
I am trying to test a dummy UIO driver to get timer interrupt events in Userspace.
I register the UIO driver as a platform driver:
static struct platform_device *uio_dummy_device;
static struct device_driver uio_dummy_driver = { .name = "uio_dummy", .bus = &platform_bus_type, .probe = uio_dummy_probe, .remove = uio_dummy_remove, .shutdown = uio_dummy_shutdown, };
/* * Main initialization/remove routines */ static int __init uio_dummy_init(void) { printk("uio_dummy_init( )\n" ); uio_dummy_device = platform_device_register_simple("uio_dummy", -1, NULL, 0); if (IS_ERR(uio_dummy_device)) return PTR_ERR(uio_dummy_device);
return driver_register(&uio_dummy_driver); }
So after the driver_register() My probe should be called but it isn't.
yes but did you register the device in your device tree or your boot file?
Why is this happening.
Thanks Nayan
