37 This driver is used by the Intel driver in X.org 6.8 and
38 XFree86 4.4 and above. It replaces the older i830 module that
39 supported a subset of the hardware in older X.org releases.
40
41 Note that the older i810/i815 chipsets require the use of the
42 i810 driver instead, and the Atom z5xx series has an entirely
43 different implementation.

51 This is the default value for the i915.force_probe module
52 parameter. Using the module parameter overrides this option.
53
54 Force probe the driver for new Intel graphics devices that are
55 recognized but not properly supported by this kernel version. It is
56 recommended to upgrade to a kernel version with proper support as soon
57 as it is available.
58
59 Use "" to disable force probe. If in doubt, use this.
60
61 Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
62 devices. For example, "4500" or "4500,4571".
63
