Hi Andrzej, one thing I noticed while looking at this:
Thanks for looking!

In VP9, probabilities are coded in the 0..255 range, so if you want to
save space here, you can go with uint8_t.
Please note that this is a hardware-specific/driver-specific structure.
And, in particular, this is not a uAPI struct. The reference code uses
32-bit quantities hence int32_t here.
