48 | This driver is used by the Intel driver in X.org 6.8 and | |
49 | XFree86 4.4 and above. It replaces the older i830 module that | |
50 | supported a subset of the hardware in older X.org releases. | |
4520f53a DV |
51 | |
52 | Note that the older i810/i815 chipsets require the use of the | |
53 | i810 driver instead, and the Atom z5xx series has an entirely | |
54 | different implementation. | |
55 | ||

56 | If "M" is selected, the module will be called i915. |

65 | Force probe the i915 driver for Intel graphics devices that are |
66 | recognized but not properly supported by this kernel version. Force | |

74 | Use "" to disable force probe. If in doubt, use this. |

157821fb | 76 | Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed |
7ef5ef5c | 77 | devices. For example, "4500" or "4500,4571". |

79 | Use "*" to force probe the driver for all known devices. Not |
80 | recommended. | |
755412e2 | 81 | |
157821fb RV |
82 | Use "!" right before the ID to block the probe of the device. For |
83 | example, "4500,!4571" forces the probe of 4500 and blocks the probe of | |
84 | 4571. | |
85 | ||
86 | Use "!*" to block the probe of the driver for all known devices. | |
