Could you tell me why ?
I can understand if textures and TCL are different due to different number
of pipelines etc, but I would have expected glxgears to work.
Also, checking the documentation for R300 kit I see that out of the
packets:
# define RADEON_3D_RNDR_GEN_INDX_PRIM 0x00002300
# define RADEON_WAIT_FOR_IDLE 0x00002600
# define RADEON_3D_DRAW_VBUF 0x00002800
# define RADEON_3D_DRAW_IMMD 0x00002900
# define RADEON_3D_DRAW_INDX 0x00002A00
# define RADEON_3D_LOAD_VBPNTR 0x00002F00
# define RADEON_CNTL_HOSTDATA_BLT 0x00009400
# define RADEON_CNTL_PAINT_MULTI 0x00009A00
# define RADEON_CNTL_BITBLT_MULTI 0x00009B00
# define RADEON_CNTL_SET_SCISSORS 0xC0001E00
only the following are marked as not supported by R300:
# define RADEON_3D_RNDR_GEN_INDX_PRIM 0x00002300
So it would seem that most of the engine is intact.
Am I missing something ?
