BITBLT_MULTI work if i put data in the agpgart space with cpu (memcpy) and then read it and put it in the framebuffer with bitblt_multi. > > > Other register that i am wondering about there use : > > RADEON_DP_MIX (0x16c8) > > Select source data location and ROP, both of which are mirrored in > DP_GUI_MASTER_CNTL. > > > RADEON_DP_GUI_MASTER_CNTL_C (0x1c84) > > Are you sure this is correct? At least on R200, 0x1c84 is a completely > different register... I may have made an error copying the value :) at least i see a RADEON_DP_GUI_MASTER_CNTL_C in radeon_reg.h in X server.
