2012-11-17drm/udl: fix stride issues scanning out stride != width*bppDave Airlie
commit 3916e1d71b62b120888aa50bcc8d9a6200fc19a7 upstream. When buffer sharing with the i915 and using a 1680x1050 monitor, the i915 gives is a 6912 buffer for the 6720 width, the code doesn't render this properly as it uses one value to set the base address for reading from the vmap and for where to start on the device. This fixes it by calculating the values correctly for the device and for the pixmap. No idea how I haven't seen this before now.

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>
