Subject: RE: [RESEND PATCH 1/1] drm/i915/glk: Add MODULE_FIRMWARE for
 Geminilake

Hi all:

We tested GLK DMC 1.04 FW in last week of September 2017, using the latest drm-tip version for that time (4.14.0-rc2) and according to our results we could declare this FW as acceptable and healthy to be used with kernel version 4.14 . 
However, we cannot guarantee quality and healthy of this FW if it is used in top of current drm-tip kernel (4.17-rc0).

Best Regards
Luis Botello

Luis, Elio, can you guys confirm that this firmware is tested and healthy? And also, give a tested-by to this patch please?
