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
