1. In RADEONSetupForScanlineImageWrite dp_gui_master_cntl_clip does not depend on endianness unlike other similar functions.. Is it right ?
I tested it with all possible value do not see anychange :(
2. It appears that PIX_ORDER field in gui_cntl is *not* used by microcode. In fact, I can't find DP_GUI_MASTER anywhere in R300 docs.
It seems that PIX_ORDER & LSB_TO_MSB are duplicated constant.
# define RADEON_GMC_BYTE_PIX_ORDER (1 << 14) # define RADEON_GMC_BYTE_MSB_TO_LSB (0 << 14) # define RADEON_GMC_BYTE_LSB_TO_MSB (1 << 14)
Is there any register with similarities with DP_GUI_MASTER in your doc ? Or any which deal with the endianness
So, perhaps, R300 hardware would use the same endiannes settings for both MMIO and ACCEL modes ?
Tested too but no change. I will try to test again because with all change i made in all place i am no more sure of what i do. My code is becoming a real mess :)
Thx for your comments
Btw i still do not find a way to make r300_demo works but i am working on it. I think that this maybe related to the problem we have here.
best, Jerome Glisse
