I don't suppose someone out there with r128 docs would fill me in on how the second head is controlled on r128. with that info I will try and refine my patches. as commented in r128_reg.h in the crtc2 section are all the crtc2 regs listed? or were some left out? also have is the DAC, cursor and pll stuff done on the second head? Radeon seems to have dedicated regs defined in radeon_regs.h for these functions, but r128 does not have them. Does r128 even have hardware cusor support on the seconf head? Also which models support dual head? I arbitrarily chose the mobility models since those have been the only ones I've heard of to support this. If someone could give me an overview setting up the 2nd crtc I appreciate it. Thanks, Alex --- "Mike A.
