Thanks,
I have managed to get it all to work now, there were a couple of issues.
1 The case statement for LUT8 was missing in the colour selection routine of
savage4.c so my test in 8 bit mode was using software fall back. I have fixed
that.
2 There is a macro that waits for the GPU hardware to become ready, it was not
yielding (it just loops while incrementing a counter!) so the CPU load was
much, much higher than it should be, I have sorted that out now by adding a
usleep call and it is now behaving much better. I have also added a non
blocking function to call to test if the GPU is busy to help with multitasking.
The CPU loading is now sub 0.1% for my program which was what I had expected.
Thanks tor your help,
Tim
