Readding intel-gfx since this is interesting for everyone. On Thu, Sep 4, 2014 at 8:09 PM, Clint Taylor wrote: > I will attempt to improve my patch submissions process.

Usually I reply to the previous patch version to avoid threads nesting too badly, but other people reply to the last review comment. It doesn't really matter.

Pixel replicated modes should be 720 horizontal pixel and pixel
replicated by the HW across the HDMI cable at 2X pixel clock. Current
horizontal resolution of 1440 does not allow pixel duplication to
occur and scaling artifacts occur on the TV. HDMI certification
7-26 currently fails for all pixel replicated modes. This change fizes
the HDMI certification issues with 480i/576i.

As stated before I think I would have preferred explicit /2 here, but
if you prefer to have it this way I can live with it.
Sorry, I missed the other patches comments. The CEA-861-E specification
actually has the pixel doubled values in (Table 3) the detailed sync
information data, so it does make sense to have the doubled values in
the table with /2. I prefer the actual values myself, but I am willing
to use either method.
