<span class="quote">> Hi all,
> Currently I'm evaluating the suspend/resume speed on my laptop,
> and it was found the switching from Graphic Mode to text mode vt has taken
> more
> than 200ms, and according to the ftrace result, after Xorg received
> the signal from kernel, it waits for 200ms+ until finally issue the
> ioctl VT_RELDISP, which makes the kernel blocking at this flag to be
> set.
> As people replied to me in maillist: Because it's been asked to set the
> hardware back to text mode, which requires reprogramming the GPU, which
> takes time.

> The GPU is：
> 00:02.0 VGA compatible controller: Intel Corporation Broadwell-U
> Integrated Graphics (rev 09) (prog-if 00 [VGA controller])
> Subsystem: Apple Inc. Broadwell-U Integrated Graphics
> driver in use: i915
> Xorg version:
> X.Org X Server 1.18.3
> Release Date: 2016-04-04

> Any idea how to track this ? thanks very much.
