Hi,
I have an intel abit IL90MV mother board :
- i945GM chipset
- intel core2duo t5600
- 1Gb RAM
The mobo is connected through HDMI to a samsung PDP which is HDReady
(1280x720p and 1920x1080i).
I want to thank you for the big work you are doing on those drivers
and to tell you that I understand the code is "bleeding edge code".
I just want to give you some feedback about what's going on with my hardware.
If you need me to make some more tests, just let me know I'll do my
best to help you.
Distro : gentoo "stable" uptodate
you can find the lscpi at the end of the mail.
currently I'm using Xorg + Xrandr to display video through my HDMI
output (aka TMDS-1)
Except some little problems under X (some synchro error and some
tearing @ 1280x720) everything seems to work fine.
I'm trying to remove the whole XOrg server to replace it by a framebuffer.
Since I have an intel graphic card (GMA950) I'm trying to use the the
drm-modesetting-101 branch to have a correct output (1280x720).
For the moment, I was not able to make it work.
Here is the whole story :
Xorg : some output of the Xorg.log (will be usefull later)
Xorg probe all the outputs of the 945GM : the interesting one is TMDS-1

Once Xorg has been initilised I use Xrandr to finish the hardware set up :

xrandr --output LVDS --off

Everything works like a charm.
Now, about the DRM modesetting stuff
Yesterday I tried to set up the drm / intelfb by checking out the
latest git modesetting-101.
Compilation works fine, initialisation seems ok except that EDID Probe
does not work :

intelfb is created, my screen changes but nothing is displayed on it
except some coloured snow.
I tried to mplayer something on it (using vo fbdev / vo fbdev2),
mplayer does not complain but nothing appears on the screen (TMDS-1).

Anyway, I tried to force the probing by "hacking into the code" :
replaced in drm_crtc.c :
{ DRM_MODE("640x480", DRM_MODE_TYPE_DEFAULT, 25200, 640, 656,
752, 800, 0, 480, 490, 492, 525, 0,
V_NHSYNC | V_NVSYNC) }, /* [EMAIL PROTECTED] */
by the modeline value found with Xorg
{ DRM_MODE("1280x720", DRM_MODE_TYPE_DEFAULT, 74250, 1280, 1720,
1760, 1980, 0, 720, 725, 730, 750, 0,
V_PHSYNC | V_PVSYNC) }, /* 720p */
to force the drm to set the graphic card in 720p mode

after init, my screen shows : "Mode is not supported". If I switch
using fbset to 640x480 the coloured snow appears again. If I switch
back to 1280x720 I got the "Mode is not supported"
I don't know what to do now.
Could you please give me an idea of what to do next to provide you
some usefull information ?
Thank you for everything you are doing.
