2012-03-20drm/usb: move usb support into a separate moduleDave Airlie

2012-03-15drm/udl: initial UDL driver (v4)Dave Airlie
This is an initial drm/kms driver for the displaylink devices. Supports fb_defio, supports KMS dumb interface supports 24bpp via conversion to 16bpp, hw can do this better. supports hot unplug using new drm core features. On an unplug, it disables connector polling, unplugs connectors from sysfs, unplugs fbdev layer (using Kay's API), drops all the USB device URBs, and call the drm core to unplug the device. This driver is based in large parts on udlfb.c so I've licensed it under GPLv2. Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-03-15drm: add core support for unplugging a device (v2)Dave Airlie
Two parts to this, one is simple unplug from sysfs for the device node. The second adds an unplugged state, if we have device opens, we just set the unplugged state and return, if we have no device opens we drop the drm device. If after a lastclose we discover we are unplugged we then drop the drm device. v2: use an atomic for unplugged and wrap it for users, add checks on open + mmap + ioctl entry points.

2012-03-15drm/modeset: add helper to unplug all connectors from sysfsDave Airlie
In order to get correct ordering at hot-unplug for userspace, we need to tear down all the sysfs bits at the correct time. This adds a helper to allow drivers to remove the sysfs nodes for all connectors. Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-03-15drm/sysfs: protect sysfs removal code against being run twice.Dave Airlie

2012-03-15udlfb: remove sysfs framebuffer device with USB .disconnect()Kay Sievers
The USB graphics card driver delays the unregistering of the framebuffer device to a workqueue, which breaks the userspace visible remove uevent sequence. Recent userspace tools started to support USB graphics card hotplug out-of-the-box and rely on proper events sent by the kernel. The framebuffer device is a direct child of the USB interface which is removed immediately after the USB .disconnect() callback. But the fb device in /sys stays around until its final cleanup, at a time where all the parent devices have been removed already. To work around that, we remove the sysfs fb device directly in the USB .disconnect() callback and leave only the cleanup of the internal fb data to the delayed work. Before: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) remove /2-1.2:1.0/graphics/fb0 (graphics) After: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) Cc: stable@vger.kernel.org Tested-by: Bernie Thompson <bernie@plugable.com> Acked-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

Also change the function to not give up when it finds the first connector without and encoder. A simpler approach would be to just remove the function completely as it's unused currently.
