X server and PCI_MAGIC_IO_RANGE

[KIYOHARA Takashi <kiyohara%kk.iij4u.or.jp@localhost>]

Hi again,


Some powerpc machines like bebox fail executing "Xorg -configure"
with this log.

[  3158.559] (WW) xf86EnableIO -1
[  3158.562] (II) xf86EnableIO: ffffffff
[  3158.565] (WW) Can't map IO space!  
[  3158.568] No devices to configure.  Configuration failed.


I think this reason is failed to mmap() with PCI_MAGIC_IO_RANGE.
The mmap() was call before to initialize to xf86Info.screenFd.


hw/xfree86/common/xf86Init.c:InitOutput()
  hw/xfree86/loader/loader.c:LoaderInit()
    print "Loader magic:\n"
    print "Module ABI versions\n"
  hw/xfree86/common/xf86Configure.c:DoConfigure()
    print "List of video drivers:\n"
    xf86LoadModules()
      print modules name...
    hw/xfree86/os-support/bsd/ppc_video.c:xf86EnableIO()
#ifdef PCI_MAGIC_IO_RANGE
      print "xf86EnableIO %d\n", xf86Info.screenFd
      mmap(,,,, xf86Info.screenFd, )
      print "xf86EnableIO: %08x\n"
      if (MAP_FAILED) {
        print "Can't map IO space!\n"
        return FALSE;
      }
      return TRUE;
#else
      return TRUE;
#endif
    if (nDevToConfig <= 0)
      print "No devices to configure.  Configuration failed.\n"
  :
  :
  hw/xfree86/os-support/bsd/bsd_init.c:xf86OpenConsole();
    xf86Info.consoleFd = fd;


Thanks,
