From 79e539453b34e35f39299a899d263b0a1f1670bd Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Fri, 7 Nov 2008 14:24:08 -0800 Subject: DRM: i915: add mode setting support This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.
