Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for the IDT ICS932S401 chip family.
|
||
|
|
|
||
|
|
This chip has 4 clock outputs--a base clock for the CPU (which is likely
|
||
|
|
multiplied to get the real CPU clock), a system clock, a PCI clock, a USB
|
||
|
|
clock, and a reference clock. The driver reports selected and actual
|
||
|
|
frequency. If spread spectrum mode is enabled, the driver also reports by what
|
||
|
|
percent the clock signal is being spread, which should be between 0 and -0.5%.
|
||
|
|
All frequencies are reported in KHz.
|
||
|
|
|
||
|
|
The ICS932S401 monitors all inputs continuously. The driver will not read
|
||
|
|
the registers more often than once every other second.

Special Features
|
||
|
|
----------------
|
||
|
|
|
||
|
|
The clocks could be reprogrammed to increase system speed. I will not help you
|
||
|
|
do this, as you risk damaging your system!
