The accuracy of Bzy_Mhz and Busy% depend on reading the TSC, APERF, and MPERF close together in time. When there is a very short measurement interval, or a large system is profoundly idle, the changes in APERF and MPERF may be very small. They can be small enough that an expensive interrupt between reading APERF and MPERF can cause the APERF/MPERF ratio to become inaccurate, resulting in invalid calculation and display of Bzy_MHz. A dummy APERF read of APERF makes this problem much more rare. Apparently this 1st systemn call after exiting a long stretch of idle is when we typically see expensive timer interrupts that cause large jitter. For the cases that dummy APERF read fails to prevent, we compare the latency of the APERF and MPERF reads. If they differ by more than 2x, we re-issue them. Signed-off-by:

The column "GFX%c6" show the percentage of time the GPU is in the "render C6" state, rc6. Deep package C-states on several systems depend on the GPU being in RC6.

The new IRQ column shows how many interrupts have occurred on each CPU during the measurement inteval. This information comes from the difference between /proc/interrupts shapshots made before and after the measurement interval. The first row, the system summary, shows the sum of the IRQS for all CPUs during that interval. Signed-off-by:

Following changes have been made: - changed MSR_NHM_TURBO_RATIO_LIMIT to MSR_TURBO_RATIO_LIMIT in debug print for consistency with Developer Manual - updated definition of bitfields in MSR_TURBO_RATIO_LIMIT and appropriate parsing code - added x200 to list of architectures that do not support Nahlem compatible definition of MSR_TURBO_RATIO_LIMIT register (x200 has the register but bits definition is custom) - fixed typo in code that parses MSR_TURBO_RATIO_LIMIT (logical instead of bitwise operator) - changed MSR_TURBO_RATIO_LIMIT parsing algorithm so the print out had the same order as implementations for other platforms Signed-off-by:

x200 does not enable any way to programmatically obtain bus clock speed. Bclk for the architecture has a fixed value of 100 MHz. At the same time x200 cannot be included in has_snb_msrs since it does not support C7 idle state. prior to this patch, MHz values reported on this chip were erroneously calculated using bclk of 133MHz, causing MHz values to be reported 33% higher than actual.
