Hi, I previously used Intel PCM on linux and now am trying it out on windows. I have to say that it was so much easier to use on linux because of the structure. For windows, I am having trouble finding what I have to do to use the PCM API. I see IntelPcm.dll but I do not know where to place it! And how do I use the API from my applications? What all headers do I need? It would be really helpful if you could provide such a document! Thanks, Pranith

Pranith,

on Windows please look at the MSVC project in the PCM_Win directory. It contains all you need to compile pcm.exe on Windows from the example source file cpucounterstest.cpp . Same as on Linuxit compiles the sameCPP files into object files and linkes them into a single executable. The only difference is the "Driver" class that loads Windows msr kernel driver: #include "../PCM_Win/windriver.h". See the usage of the driver class in the cpucounterstest.cpp

Best regards,
Roman

Hello Pranith,
Roman has listed how to build PCM on Windows.
My experience is below...
I followed the instructions in the WINDOWS_HOWTO.rtf file.
Short version:
1) cd PCM_Win
2) type 'pcm.vcproj'
Visual Studio loads (maybe convertsthe project file)
3) Hit the 'Build->Build Solution' visual studio menu item
This should build pcm.exe
4) cd .. # now you should be back in the main PCM dir
5) copy PCM_Win\Debug\pcm.exe .
Now we've built the executable... we still need a Ring0 level driver
You can build your own but on Win7 64bit the driver has to be signed or you have to run in debug mode.
Below I get a prebuilt, signed WinRing0 driver from Open-Hardware-Monitor.
6) download Open-Hardware-Monitor (from http://code.google.com/p/open-hardware-monitor/downloads/list)
I picked the latest version ver 0.4.0-beta URL http://open-hardware-monitor.googlecode.com/files/openhardwaremonitor-v0.4.0-beta.zip
7) unzip openhardwaremonitor-v0.4.0-beta.zip
8) copyOpenHardwareMonitor\winring* .
So now the winring0*.dll and winring0*.sys files should be in same dir as pcm.exe
9) now pcm is ready to go. You should be able to do:
.\pcm.exe 1

Thanks Roman and Patrick for the information.

Patrick,

I was able to follow you until 6) where you tell me to copy winring0* from openhardwaremonitor. I downloaded the zip file and did not find any winrin0* files. Maybe they have been moved? Is there anywhere else I can find them?

Thanks,
Pranith

open-hardware-monitor has apparently stopped shipping winring0.

RealTemp still has it.
You can go to http://www.techpowerup.com/downloads/SysInfo/Real_Temp and click on 'Real Temp 3.70' or
see http://www.techpowerup.com/downloads/2089/Real_Temp_3.70.html
and click on the 'Download Now'icon.
