help
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.
config DRM_I915_CAPTURE_ERROR
bool "Enable capturing GPU state following a hang"
depends on DRM_I915
default y
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://drm.pages.freedesktop.org/intel-docs/how-to-file-i915-bugs.html
If in doubt, say "Y".
config DRM_I915_COMPRESS_ERROR
bool "Compress GPU error state"
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
bool "Always enable userptr support"
depends on DRM_I915
select MMU_NOTIFIER
default y
help
This option selects CONFIG_MMU_NOTIFIER if it isn't already
selected to enabled full userptr support.
If in doubt, say "Y".

select DRM_I915_GVT
select KVM_EXTERNAL_WRITE_TRACKING
select VFIO_MDEV
help
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:
https://github.com/intel/gvt-linux/wiki.
If in doubt, say "N".
config DRM_I915_PXP
bool "Enable Intel PXP support"
depends on DRM_I915
depends on INTEL_MEI && INTEL_MEI_PXP
default n
help
PXP (Protected Xe Path) is an i915 component, available on graphics
version 12 and newer GPUs, that helps to establish the hardware
protected session and manage the status of the alive software session,
as well as its life cycle.
config DRM_I915_DP_TUNNEL
bool "Enable DP tunnel support"
depends on DRM_I915
depends on USB4
select DRM_DISPLAY_DP_TUNNEL
default y
help
Choose this option to detect DP tunnels and enable the Bandwidth
Allocation mode for such tunnels. This allows using the maximum
resolution allowed by the link BW on all displays sharing the
link BW, for instance on a Thunderbolt link.
If in doubt, say "Y".
