To take over the device the dedicated driver + * first has to remove the generic driver. Aperture functions manage + * ownership of framebuffer memory and hand-over between drivers. + * + * Graphics drivers should call aperture_remove_conflicting_devices() + * at the top of their probe function. The function removes any generic + * driver that is currently associated with the given framebuffer memory. + * An example for a graphics device on the platform bus is shown below. + * + * .. code-block:: c + * + * static int example_probe(struct platform_device *pdev) + * { + * struct resource *mem; + * resource_size_t base, size; + * int ret; + * + * mem = platform_get_resource(pdev, IORESOURCE_MEM, 0); + * if (!mem) + * return -ENODEV; + * base = mem->start; + * size = resource_size(mem); + * + * ret = aperture_remove_conflicting_devices(base, size, false, "example"); + * if (ret) + * return ret; + * + * // Initialize the hardware + * ... + * + * return 0; + * } + * + * static const struct platform_driver example_driver = { + * .probe = example_probe, + * ... + * }; + * + * The given example reads the platform device's I/O-memory range from the + * device instance. An active framebuffer will be located within this range. + * The call to aperture_remove_conflicting_devices() releases drivers that + * have previously claimed ownership of the range and are currently driving + * output on the framebuffer. If successful, the new driver can take over + * the device. + * + * While the given example uses a platform device, the aperture helpers work + * with every bus that has an addressable framebuffer. In the case of PCI, + * device drivers can also call aperture_remove_conflicting_pci_devices() and + * let the function detect the apertures automatically. Device drivers without + * knowledge of the framebuffer's location can call + * aperture_remove_all_conflicting_devices(), which removes all known devices. + * + * Drivers that are susceptible to being removed by other drivers, such as + * generic EFI or VESA drivers, have to register themselves as owners of their + * framebuffer apertures. Ownership of the framebuffer memory is achieved + * by calling devm_aperture_acquire_for_platform_device(). If successful, the + * driveris the owner of the framebuffer range.
