496818f08a drm/i915: take struct mutex around fb unref
Need to do this in case the unref ends up doing a free.

2ebed176a7 drm/i915: Set framebuffer alignment based upon the fence constraints.
Set the request alignment to 0, and leave it up to i915_gem_object_pin()
to set the appropriate alignment to match the fence covering the object.

Eric Anholt mentioned that the pinning code is meant to choose the
maximum of the request alignment and that of the fence covering the
object... However currently, the pinning code will only apply the fence
constraints if the supplied alignment is 0.

725e30ad66 drm/i915: Skip SDVO/HDMI init when the chipset tells us it's not present.
This saves startup time from probing SDVO, and saves setting up HDMI outputs
on G4X devices that don't have them.

71acb5eb8d drm/i915: add support for physical memory objects
This is an initial patch to do support for objects which needs physical
contiguous main ram, cursors and overlay registers on older chipsets.

These objects are bound on cursor bin, like pinning, and we copy
the data to/from the backing store object into the real one on attach/detach.

notes:
possible over the top in attach/detach operations.
no overlay support yet.

0c7c266475 drm: drop DRM_IOCTL_MODE_REPLACEFB, add+remove works just as well.
The replace fb ioctl replaces the backing buffer object for a modesetting
framebuffer object.  This can be acheived by just creating a new
framebuffer backed by the new buffer object, setting that for the crtcs
in question and then removing the old framebuffer object.

79e539453b DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs.
Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are
supported.  HDMI, DisplayPort and additional SDVO output support will
follow.

Support for the mode setting code is controlled by the new 'modeset'
module option.  A new config option, CONFIG_DRM_I915_KMS controls the
default behavior, and whether a PCI ID list is built into the module for
use by user level module utilities.

Note that if mode setting is enabled, user level drivers that access
display registers directly or that don't use the kernel graphics memory
manager will likely corrupt kernel graphics memory, disrupt output
configuration (possibly leading to hangs and/or blank displays), and
prevent panic/oops messages from appearing.  So use caution when
enabling this code; be sure your user level code supports the new
interfaces.

A new SysRq key, 'g', provides emergency support for switching back to
the kernel's framebuffer console; which is useful for testing.
