I forgot the __...__ macros in there * instead of the function arguments :P * - Added a workaround for the 1600x1200 bug (Text mode corrupts * when you exit from any 1600x1200 mode and 1280x1024@85Hz. I * suspect this is a BIOS bug (hence the 1280x1024@85Hz case)). * For now I'm switching to 800x600@60Hz then to 80x25 text mode * and then restoring the registers - very ugly indeed. * * 15/10/2001 * - Improved 1600x1200 mode set workaround. The previous workaround * was causing mode set problems later on. * * 18/10/2001 * - Fixed a bug in I830BIOSLeaveVT() which caused a bug when you * switched VT's */ /* * 07/2002 David Dawes * - Add Intel(R) 855GM/852GM support. */ /* * 07/2002 David Dawes * - Cleanup code formatting. * - Improve VESA mode selection, and fix refresh rate selection. * - Don't duplicate functions provided in 4.2 vbe modules. * - Don't duplicate functions provided in the vgahw module. * - Rewrite memory allocation. * - Rewrite initialisation and save/restore state handling. * - Decouple the i810 support from i830 and later. * - Remove various unnecessary hacks and workarounds. * - Fix an 845G problem with the ring buffer not in pre-allocated * memory. * - Fix screen blanking. * - Clear the screen at startup so you don't see the previous session. * - Fix some HW cursor glitches, and turn HW cursor off at VT switch * and exit. * * 08/2002 Keith Whitwell * - Fix DRI initialisation. * * * 08/2002 Alan Hourihane and David Dawes * - Add XVideo support. * * * 10/2002 David Dawes * - Add Intel(R) 865G support. * * * 01/2004 Alan Hourihane * - Add Intel(R) 915G support. * - Add Dual Head and Clone capabilities. * - Add lid status checking * - Fix Xvideo with high-res LFP's * - Add ARGB HW cursor support * * 05/2005 Alan Hourihane * - Add Intel(R) 945G support. * * 09/2005 Alan Hourihane * - Add Intel(R) 945GM support. * * 10/2005 Alan Hourihane, Keith Whitwell, Brian Paul * - Added Rotation support * * 12/2005 Alan Hourihane, Keith Whitwell * - Add Intel(R) 965G support. */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #ifndef PRINT_MODE_INFO #define PRINT_MODE_INFO 0 #endif #include #include #include #include #include "xf86.h" #include "xf86_OSproc.h" #include "xf86Resources.h" #include "xf86RAC.h" #include "xf86cmap.h" #include "compiler.h" #include "mibstore.h" #include "vgaHW.h" #include "mipointer.h" #include "micmap.h" #include "shadowfb.h" #include #include "fb.h" #include "miscstruct.h" #include "xf86xv.h" #include #include "vbe.h" #include "vbeModes.h" #include "shadow.h" #include "i830.h" #ifdef HAS_MTRR_SUPPORT #include #endif #ifdef XF86DRI #include "dri.h" #endif #define BIT(x) (1 << (x)) #define MAX(a,b) ((a) > (b) ?
