A pointer to a probe callback is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

Commit 4410f391 ("fbdev: add support for handoff from firmware to hw framebuffers") didn't add fb_destroy operation to efifb. Fix it and change aperture_size to match size passed to request_mem_region.

With KMS we have ran into an issue where we really want the KMS fb driver to be the one running the console, so panics etc can be shown by switching out of X etc. However with vesafb/efifb built-in, we end up with those on fb0 and the KMS fb driver on fb1, driving the same piece of hw, so this adds an fb info flag to denote a firmware fbdev, and adds a new aperture base/size range which can be compared when the hw drivers are installed to see if there is a conflict with a firmware driver, and if there is the firmware driver is unregistered and the hw driver takes over. It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.

efifb will attempt to ioremap a framebuffer even if its starting address is 0, failing and causing an ugly backtrace in the process. Exit before probing if this is the case.

The current logic for dmi matching in efifb does not allow efifb to load on all hardware that we can dmi match for. For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a Apple (MacBook) and EFI framebuffer driver will not load (you will have no video). This specific hardware is efi v1.10, so we have UGA and not GOP. Without special bootloader magic (i.e. extra elilo patches for UGA graphics detection) no screen info will be passed to the kernel and as a result efifb will not load. This patch allows the dmi match to happen by moving it to earlier in efifb_init, and sets the video type (in set_system) so that efifb can load when we have a valid dmi match and already know the specifics of the hardware. Without this patch the efifb driver will fail to load in the event screen info is not found and passed in by the bootloader, being that we will never get to look for a dmi match. A primary reason for matching with dmi is because not all bootloaders detect the video info properly. The solution is that in the event of a dmi match, we should set screen_info.orig_video_isVGA. Most bootloaders fail to set screen info on Apple hardware, and this is a big problem for people who use Apple hardware. Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the issue, the dmi match now works, EFI framebuffer now loads and video works.

Remove imacfb entirely, merging its DMI table into the (otherwise very similar) efifb driver. This also adds hardware support for many of the newer Intel Apple hardware. This has been fairly well tested; we've been shipping it in Fedora for some time.

This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output Protocol (GOP) is produced. Therefore, the boot loader needs to query the UEFI firmware with appropriate Output Protocol and pass the video information to the kernel. As a result of GOP protocol, an EFI framebuffer driver is needed for displaying console messages. The patch adds a EFI framebuffer driver. The EFI frame buffer driver in this patch is based on the Intel Mac framebuffer driver. The ELILO bootloader takes care of passing the video information as appropriate for EFI firmware. The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI platform.
