Hi, After launching several times flgrx and dumping the reg and diffing against what was reg with r300 here is the list of reg that have always on my card (RV350NJ) the same value (for the same screen resolution). I think that one of the unknown reg maybe a group of them are the key one but anyway i wasn't able to write to most of this reg. They may are read only thus i tried writing random things in register near them but i only succeed to lockup the card and the reg i was interested in didn't change.
Thus if anyone got any info on any of this reg, some must be in old radeon spec but i haven't this specs and don't understand from their name what they do (not all :)). Maybe dumping value that fglrx set in this reg on other card could be usefull.... For the know reg i have put their name either taken from xorg reg list of from fb radeon one. The second value is what fglrx set in them r300 value is different. 0x0030 0x5133a3a0 RADEON_BUS_CNTL 0x0044 0x00080007 RADEON_GEN_INT_STATUS 0x0148 0xfffff000 RADEON_MC_FB_LOCATION 0x014c 0xfdfffc00 RADEON_MC_AGP_LOCATION 0x0224 0x00000a00 RADEON_CRTC_OFFSET 0x023c 0xf0000000 DISPLAY_BASE_ADDR (fb radeon) 0x0260 0x00500000 RADEON_CUR_OFFSET 0x033c 0xf0000000 CRTC2_DISPLAY_BASE_ADDR (fb radeon) 0x03f8 0x04000080 RADEON_CRTC2_GEN_CNTL 0x0700 0xf0001000 RADEON_CP_RB_BASE 0x0704 0x00080f11 RADEON_CP_RB_CNTL 0x0738 0x00000000 RADEON_CP_IB_BASE 0x078c 0x00000000 ??
