While I was working on mergedfb support for the radeon video overlay, I
happened upon and fixed a bug in the setting of ECP. in
RADEONAllocAdaptor() and RADEONDisplayVideo(), the current code looks
something like this:
if(info->ModeReg.dot_clock_freq < 17500)
ecp_div = 0;
else
ecp_div = 1;
If the overlay is on the second crtc, I would think it should look
something like this:
if ((info->MergedFB && info->OverlayOnCRTC2) || info->IsSecondary)
dot_clock = info->ModeReg.dot_clock_freq_2;
else
dot_clock = info->ModeReg.dot_clock_freq;
if(dot_clock < 17500)
ecp_div = 0;
else
ecp_div = 1;
This fix in already in my mergedfb code
(http://bugs.xfree86.org/show_bug.cgi?id=276).
