--- Comment #33 from Jean Delvare <kh...@linux-fr.org> 2013-02-25 08:44:07 --- (In reply to comment #31) > Unfortunately the CPU only reports one value for all cores combined, not per > CPU. You can see that clearly when the load is high. This is odd. But then shouldn't "Core power" be changed to "Cores power"? Also, not sure how "Pkg power" can be so much higher than "Core power". What else in the CPU package is drawing significant power? > The initial energy reading starts with the current value in the registers.

Then I question the value of these measurements for user-space. I assume that the driver uses these values to compute the power figures, so the energy values are not only confusing but also redundant. Don't you think exposing the power values would be sufficient and less confusing? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Everyone hates slow websites.
