+ 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.

+config DRM_I915_FORCE_PROBE
+ string "Force probe i915 for selected Intel hardware IDs"
+ depends on DRM_I915
+ help
+ This is the default value for the i915.force_probe module
+ parameter. Using the module parameter overrides this option.
+
+ Force probe the i915 driver for Intel graphics devices that are
+ recognized but not properly supported by this kernel version. Force
+ probing an unsupported device taints the kernel. It is recommended to
+ upgrade to a kernel version with proper support as soon as it is
+ available.
+
+ It can also be used to block the probe of recognized and fully
+ supported devices.
+
+ Use "" to disable force probe. If in doubt, use this.
+
+ Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed
+ devices. For example, "4500" or "4500,4571".
+
+ Use "*" to force probe the driver for all known devices. Not
+ recommended.
+
+ Use "!" right before the ID to block the probe of the device. For
+ example, "4500,!4571" forces the probe of 4500 and blocks the probe of
+ 4571.
+
+ Use "!*" to block the probe of the driver for all known devices.

+ help
+ This option enables capturing the GPU state when a hang is detected.
+ This information is vital for triaging hangs and assists in debugging.
+ Please report any hang for triaging according to:
+ https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
+
+ If in doubt, say "Y".
+
+config DRM_I915_COMPRESS_ERROR

+ depends on DRM_I915_CAPTURE_ERROR
+ select ZLIB_DEFLATE
+ default y
+ help
+ This option selects ZLIB_DEFLATE if it isn't already
+ selected and causes any error state captured upon a GPU hang
+ to be compressed using zlib.
+
+ If in doubt, say "Y".
+
+config DRM_I915_USERPTR

+ 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 KVM.
+
+ Note that this driver only supports newer device from Broadwell on.
+ For further information and setup guide, you can visit:

+ version 12 and newer GPUs, that helps to establish the hardware
