Merge branch 'modesetting-import' into master
This reintroduces a "hardware" driver to the xfree86 directory.
Unlike the drivers that xorg used to include in the source tree, that
needed independent release schedules to get hardware support out the
door, the modesetting driver shouldn't change much as new hardware
gets released. A lot of what this driver needs to do is just keep up
with server ABI changes.
This import was done by taking xf86-video-modesetting-0.9.0, and
running this script with 'git-filter-branch -f --tree-filter
~/bin/modesetting-filter':

This is a non-accelerated +driver, the following framebuffer depths are supported: 8, 15, 16, 24. +All visual types are supported for depth 8, and TrueColor visual is +supported for the other depths. RandR 1.2 is supported. +.SH SUPPORTED HARDWARE +The +.B modesetting +driver supports all hardware where a KMS driver is available. +modesetting uses the Linux DRM KMS ioctls and dumb object create/map. +.SH CONFIGURATION DETAILS +Please refer to __xconfigfile__(__filemansuffix__) for general configuration +details. This section only covers configuration details specific to +this driver. +.PP +For this driver it is not required to specify modes in the screen +section of the config file. The +.B modesetting +driver can pick up the currently used video mode from the kernel +driver and will use it if there are no video modes configured. +.PP +For PCI boards you might have to add a BusID line to the Device +section.
