<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US">I couldn't find an appropriate mailing list to report this on, so I'm mailing the two of you as you've both touched the clock code in intel_gpu_top.<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US">I'm running an Ivy Bridge Mobile chipset and trying to use intel_gpu_top and intel_stepping to see the GPU clock frequencies. In both cases, the clocks are "unknown".<br>
<br>
When I look at the code, it seems that there's just no code path to handle this devid, though I'm not sure as I'm not very good at understanding code. I see in intel_chipset.h that device id 0x0166 = PCI_CHIP_IVYBRIDGE_M_GT2 and that none of the "if's" in
print_clock_info ultimately point to this device type.<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US">Do either of you know why this would be? Is it just a case of coding for the majority of chipset configurations?<o:p></o:p></span></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US">If it's just the case of it not yet being handled, I'd be open to trying to add support for it if you could point me to the necessary chip documentation.<o:p></o:p></span></p>
