Linux-2.6.17/Documentation/cpu-freq/cpufreq-nforce2.txt

Version: ~ [ 2.6.16 ] ~ [ 2.6.17 ] ~
Architecture: ~ [ ia64 ] ~ [ i386 ] ~ [ arm ] ~ [ ppc ] ~ [ sparc64 ] ~

  1 
  2 The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 plattforms.
  3 
  4 This works better than on other plattforms, because the FSB of the CPU
  5 can be controlled independently from the PCI/AGP clock.
  6 
  7 The module has two options:
  8 
  9         fid:     multiplier * 10 (for example 8.5 = 85)
 10         min_fsb: minimum FSB
 11 
 12 If not set, fid is calculated from the current CPU speed and the FSB.
 13 min_fsb defaults to FSB at boot time - 50 MHz.
 14 
 15 IMPORTANT: The available range is limited downwards!
 16            Also the minimum available FSB can differ, for systems 
 17            booting with 200 MHz, 150 should always work.
