[Openchrome-users] CX700 video

Not yet, we know it has a different hardware decoder, not sure if it is
backward compatible

Yes, we found minimal differences (the proReg and minor tweaking), the
code is working on all chipsets with the CME video engine: K8M890,
P4M890, CX700, not tested in P4M900 yet.

We have been talking about that in #unichrome

I started a code cleanup, I added a VideoEngine variable and modified
the xv code, so this code:

if (pVia->ChipId == PCI_CHIP_VT3259 || pVia->ChipId == PCI_CHIP_VT3327
|| pVia->ChipId == PCI_CHIP_VT3336 || pVia->ChipId == PCI_CHIP_VT3157 ||
pVia->ChipId == PCI_CHIP_VT3364)

will be replaced by this:
if (pVia->VideoEngine == VIDEO_ENGINE_CME)

I will commit it when finish my tests.

Regards,
Gabriel.
