| 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 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. |
