[Intel-gfx] [PATCH] Correct drm display mode table about 1856x1392 @75Hz mode

2015-04-02 Thread liu,lei 
From: liu,lei lei.a@intel.com

According DMT spec, vss of this mode should be 1393, vse should
be 1396.

VESA MONITOR TIMING STANDARD:

Timing Name = 1856 x 1392 @ 75Hz
Hor Total Time = 8.889;  (usec) = 320 chars = 2560 Pixels
Hor Sync Start = 6.889;  (usec) = 248 chars = 1984 Pixels
H Back Porch = 1.222;  (usec) = 44 chars = 352 Pixels

Ver Total Time = 13.333;  (msec) = 1500 lines HT – (1.06xHA)
Ver Sync Start = 12.382;  (msec) = 1393 lines
V Back Porch = 0.924;  (msec) = 104 lines

Re: [Intel-gfx] [PATCH] Correct drm display mode table about 1856x1392 @75Hz mode

2015-04-02 Thread Jani Nikula 

Please prefix the subject with drm/edid:  and send the patch to
dri-de...@lists.freedesktop.org.

In general, scripts/get_maintainer.pl will tell you where to send the
patches; intel-gfx is for stuff under drivers/gpu/drm/i915.

Thanks,
Jani.

That is indeed what the spec says. However to review this I wrote a
quick awk script to parse the spec, and that shows a few more
differences. I'll toss out a patch with the results of my script...
