[Openchrome-users] Epia EN12000 with DVI-03CG

[Jörgen Andreasen]

Hi!

I just want to report that some EPIA motherboards can have DVI
daugtherboards attached to them. The "ViaCardId" struct has to be
updated accordingly. In my case (code checked out from Subversion
repositry on 11 November):

$ diff via_id.c.dist via_id.c
172c172
<     {"VIA VT3344 (VM800) - EPIA EN",          VIA_VM800,   0x1106, 0x3344, VIA_DEVICE_CRT | VIA_DEVICE_TV},
---
>     {"VIA VT3344 (VM800) - EPIA EN",          VIA_VM800,   0x1106, 0x3344, VIA_DEVICE_CRT | VIA_DEVICE_LCD | VIA_DEVICE_TV},


I know that the EPIA SP also has a DVI daughterboard available. I have a
EPIA SP800 but no DVI daughterboard to it. It's detected by the
Unichrome/Xorg 7.0 (Ubuntu 6.06 LTSP) as "VT3118 (PM800)". In the
Openchrome driver the corresponding "ViaCardId":

    {"ASRock P4VM8",                          VIA_PM800,   0x1849, 0x3118, VIA_DEVICE_CRT},


Which suggests that DVI output will not work either, as "VIA_DEVICE_LCD"
is missing here aswell. The TV decoder would also not work as the
Openchrome driver's missing "VIA_DEVICE_TV". In the Unichrome it's
detected, though:

(--) VIA(0): Detected VIA Technologies VT1622A/VT1623 TV Encoder


Note! I haven't tested Openchrome on the EPIA SP as the Unichrome driver
is working "right-out-of-the-box".
