[Intel-gfx] [PATCH 0/3] HDMI optimization series

[Jindal, Sonika]

Hi Daniel,

That patch was already merged:
http://lists.freedesktop.org/archives/intel-gfx/2015-July/071142.html

For SKL, the above patch helped in getting the correct ISR bits set.
One option is to enable the HDMI optimization from VLV onwards.
I don't have an ivb machine to try out the issue.

Regards,
Sonika

This series breaks my funky ivb machine with the broken hpd bits: When I unplug the screen the system never invalidates the edid and so never notices that it's gone.

Now iirc you've discovered an issue in our hpd irq handler which can cause lost hpd bits, but that patch isn't in this series. And iirc I asked you to resend everything since that hw fix also wasn't in the last series. And I can't find it any more. Did I just dream about this other patch to fix hpd on big core?

Thanks, Daniel
