 * SDVO requires that the bus clock rate be between 1 and 2 Ghz, and the bus
 * clock rate is 10 times the DPLL clock.  At low resolution/refresh rate
 * modes, the bus rate would be below the limits, so SDVO allows for stuffing
 * dummy bytes in the datastream at an increased clock rate, with both sides of
 * the link knowing how many bytes are fill.
 *
 * So, for a mode with a dotclock of 65Mhz, we would want to double the clock
 * rate to 130Mhz to get a bus rate of 1.30Ghz.  The DPLL clock rate would be
 * set to 130Mhz, and the SDVO multiplier set to 2x in this register and
 * through an SDVO command.
 *
 * This register field has values of multiplication factor minus 1, with
 * a maximum multiplier of 5 for SDVO.

AppleIntelInfo.kext
===================

What do I need to do?

Step 1.) Download the project from Github and compile it with Xcode.

Step 2.) Fix file ownership and permissions.

``` sh
sudo chown -R root:wheel AppleIntelInfo.kext
sudo chmod -R 755 AppleIntelInfo.kext
```

Step 3.) Load AppleIntelInfo.kext?

``` sh
sudo kextload AppleIntelInfo.kext

or with

sudo kextutil AppleIntelInfo.kext 
```
Warning: Do not copy the kext to: /System/Library/Extensions or /Library/Extensions and do not inject it with help of the boot loader!

Step 4.) Unload AppleIntelInfo.kext?

``` sh
sudo kextunload AppleIntelInfo.kext
```

Where can I find the output?


The output of AppleIntelInfo.kext can be found with
``` sh
sudo cat /tmp/AppleIntelInfo.dat
```

Note: This has changed in version 1.2 (data no longer added to /var/log/system.log)

Settings
--------

There are five (5) settings that you can change in AppleIntelInfo.kext/Contents/Info.plist:
```
logCStates
logIGPU
logIPGStyle
logIntelRegs
logMSRs
```

All set to YES by default.

Bugs
----

All possible bugs (so called 'issues') should be filed at:

https://github.com/Piker-Alpha/AppleIntelInfo/issues

Please do **not** use my blog for this. Thank you!
