</div></div>Hm, yeah in the full HVM case we don't bring up the panel fitter and<br>
the transcoder fails to come up, which would definitely cause trouble.<br>
<br>
3.2.31 is pretty old though, can you reproduce this with a newer<br>
kernel? Tons of fixes have landed since then, and many of them aren't<br>
suitable for 3.2.x due to their invasiveness.<br></blockquote></div></div></div></blockquote><div><br>FYI: I just checked the i915_drv.c in 3.6.5 kernel.<br>It's basically the same code as I've seen in 3.2.31, just adding the LynxPoint recognition.<br>
So I believe magic for PVHVM are hidden elsewhere.<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="gmail_extra"><div class="im"><div class="gmail_quote">

And can I ask you to file a bug for this issue so it doesn't get lost?<br>
<a href="http://bugs.freedesktop.org" target="_blank">bugs.freedesktop.org</a> (see <a href="http://intellinuxgraphics.org" target="_blank">intellinuxgraphics.org</a> for bug filing<br>
instructions).<br>
<br>
Thanks,<br>

<br>It seems that the PCI hierarchy presented in the HVM does not match the expectation of intel_detect_pch() function.<br>The problem is that the PVHVM version also shares the same layout, but the driver actually works. <br>
That's what confuses me most. So far have no idea how to explain such difference in behavior.<br><br>Thanks,<br>Timothy<br><br><br></div>
