| 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. |

| help |
| This is the default value for the i915.force_probe module |
| parameter. Using the module parameter overrides this option. |
| |
| Force probe the driver for new Intel graphics devices that are |
| recognized but not properly supported by this kernel version. It is |
| recommended to upgrade to a kernel version with proper support as soon |
| as it is available. |
| |
| Use "" to disable force probe. If in doubt, use this. |
| |
| Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed |
| devices. For example, "4500" or "4500,4571". |
| |
| Use "*" to force probe the driver for all known devices. |

| config DRM_I915_CAPTURE_ERROR |

| 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". |

| 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. |

| 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 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". |
