The term "preliminary hardware support" has always caused confusion both among users and developers. It has always been about preliminary driver support for new hardware, and not so much about preliminary hardware. Of course, initially both the software and hardware are in early stages, but the distinction becomes more clear when the user picks up production hardware and an older kernel to go with it, with just the early support we had for the hardware at the time the kernel was released. The user has to specifically enable the alpha quality *driver* support for the hardware in that specific kernel version. Rename preliminary_hw_support to alpha_support to emphasize that the module parameter, config option, and flag are about software, not about hardware. Improve the language in help texts and debug logging as well. This appears to be a good time to do the change, as there are currently no platforms with preliminary^W alpha support.

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".
