This patchs adds the cec_notifier feature to the intel_hdmi part of the i915 DRM driver. It uses the HDMI DRM connector name to differentiate between each HDMI ports. The changes will allow the i915 HDMI code to notify EDID and HPD changes to an eventual CEC adapter.

Choose this option if you have a system that has "Intel Graphics
|
|
Media Accelerator" or "HD Graphics" integrated graphics,
|
|
including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
|
|
G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
|
|
Core i5, Core i7 as well as Atom CPUs with integrated graphics.
|
|
|
|
This driver is used by the Intel driver in X.org 6.8 and
|
|
XFree86 4.4 and above. It replaces the older i830 module that
|
|
supported a subset of the hardware in older X.org releases.
|
|
|
|
Note that the older i810/i815 chipsets require the use of the
|
|
i810 driver instead, and the Atom z5xx series has an entirely
|
|
different implementation.
|
|
|
|
If "M" is selected, the module will be called i915.

Choose this option if you have new Intel hardware and want to enable
|
|
the alpha quality i915 driver support for the hardware in this kernel
|
|
version. You can also enable the support at runtime using the module
|
|
parameter i915.alpha_support=1; this option changes the default for
|
|
that module parameter.
|
|
|
|
It is recommended to upgrade to a kernel version with proper support
|
|
as soon as it is available. Generally fixes for platforms with alpha
|
|
support are not backported to older kernels.

If in doubt, say "N".

Choose this option if you want to enable Intel GVT-g graphics

virtualization technology host support with integrated graphics.
|

With GVT-g, it's possible to have one integrated graphics
|
|
device shared by multiple VMs under different hypervisors.
|
|
|
|
Note that at least one hypervisor like Xen or KVM is required for
|
|
this driver to work, and it only supports newer device from
|
|
Broadwell+. For further information and setup guide, you can
|
|
visit: http://01.org/igvt-g.
|
|
|
|
Now it's just a stub to support the modifications of i915 for
|
|
GVT device model. It requires at least one MPT modules for Xen/KVM
|
|
and other components of GVT device model to work. Use it under
|
|
you own risk.

If in doubt, say "N".
