[Openchrome-users] VIA VT1631 LVDS Transmitter ??

[Jeremy C. Reed]

I am trying to track down support for VIA VT1631 LVDS.

The product webpage is at
http://www.via.com.tw/en/products/video-display/lvds/vt1631/

The manual for the EPIA MS-Series Mini-ITX board is at: 
http://www.via.com.tw/en/products/mainboards/mini_itx/epia_ms/downloads.jsp

The LVDS daughterboard itself has: "LVDS-05 Rev. A"
And the VIA chip on the daughterboard has:
 VIA
 VT1631
 0247CD Taiwan
 24A1008671

I see that Xorg's driver/xf86-video-via did have a reference to it in 
via_mode.c:

             if (R_Buffer[0] == 0x06 && R_Buffer[1] == 0x11) {       /*This is VT3191 */           
                 DEBUG(xf86DrvMsg(pScrn->scrnIndex, X_PROBED,
                                  "Found VIA LVDS Transmiter!\n"));
                 if (R_Buffer[2] == 0x91 && R_Buffer[3] == 0x31) {
                     DEBUG(xf86DrvMsg(pScrn->scrnIndex, X_PROBED,
                                      "VIA: VT1631!\n"));
                     pBIOSInfo->LVDS = VIA_VT3191; 

But that code was removed in revision 1.3 of 
driver/xf86-video-via/src/via_mode.c.

I didn't look at old openchrome code about this.

I do see that openchrome's ./unichrome/via_ch7xxx.c appears to have 
support for:

  Chrontel CH7019A LVDS Transmitter/TV Encoder
  Chrontel CH7019B LVDS Transmitter/TV Encoder
  Chrontel CH7017 LVDS Transmitter
  Chrontel CH7304 LVDS Transmitter
  Chrontel CH7305 LVDS Transmitter

But I don't see this code in Xorg's xf86-video-via. Why not?

Information from lspci and Xorg output is at
https://launchpad.net/distros/ubuntu/+bug/42607 

Is this VT1631 LVDS supported by openchrome? Xorg?

If not, any suggestions on how to get this supported?

Thanks,
