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 "[,,...]" 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.
