I found another packaged called devmsr (just development version, not
part of ports yet)<br>
<br>
It is suppose to give an interface of /dev/cpu0/msr<br>
<br>
I installed, and ran x86info and got information back about MSR.<br>
<br>
Here is the output of x86info:<br>
<br>
x86info v1.20. Dave Jones 2001-2006<br>

So I installed devmsr, and then just changed amd_msr.c to read
/dev/cpu0/msr instead of /dev/cpu/0/msr<br>
<br>
When I ran the driver, without the "NoAccel" set to true, there is NO
complaint about missing MSR info in the log file.<br>
<br>
Then, I commented out the "NoAccel" option, ran the Xorg with the amd
driver, and the desktop is the same. I can see<br>
a cursor jsut fine, and a black background, but the 3 icons on the
desktop are all screwed up. (xfce)<br>
<br>
Then I noticed something that I hadn't before. I was missing xrdb. So
Installed that.<br>
<br>
Then I ran the driver again, and this time the driver locks up on me.<br>
<br>
Is this just coincidental? Could there be something with the RGB
pallette snooping (sorry if that's the wrong term) that<br>
could be making problems?<br>
<br>
Also, I'm not 100% that the amd_msr.c is reading the MSR correctly.
Maybe it is, I'm not sure though.<br>
<br>
Just because there is no error in the log that says that MSR isn't
opened, doesn't mean it's getting read correctly.<br>
<br>
Can anyone tell from my log file?<br>

Will that give us the MSR's we need?

That will - but it might be cumbersome for people to install. We need
to figure out if there is a way to make BSD work out of the box.

Nope - its all 32 bits.
