The STOP_MACHINE kconfig symbol was removed upstream after making stop_machine() always work, commit86fffe4a61("kernel: remove stop_machine() Kconfig dependency"), and was removed from i915's Kconfig in commit21fabbebff("drm/i915: Remove select to deleted STOP_MACHINE from Kconfig"). However, I accidentally reintroduced the select when rebasing an older commit that also was dependent upon a working stop_machine. Fixes:9f267eb8d2("drm/i915: Stop the machine whilst capturing...")

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.
|
|
If M is selected, the module will be called i915. AGP support
|
|
is required for this driver to work. 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.

Choose this option if you have prerelease Intel hardware and want the

i915 driver to support it by default. You can enable such support at

runtime with the module option i915.preliminary_hw_support=1; this

option changes the default for that module option.

This option enables capturing the GPU state when a hang is detected.

This information is vital for triaging hangs and assists in debugging.

|

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".
