Maybe, but I have no other indication. Also, I'm pretty that, when in auto
power level, when I run my piglit tests, it locks at there.

Another thing I noticed: if I run the quick piglit tests at a low power level,
the total number of passed tests is higher than when I run it at an higher
speed. The failing tests explaining this difference are mostly texelFetch
related. I'll send the piglit results from both runs once I'll have set back
mclk to its default value.
