Is this future proof enough, say for Gen11?
As far as I can see, this fits.
No objection to bump it to 16/32bits if you'd like.
Feel like I've asked you this before, sorry - nothing in the
future will need per slice subslice mask?
As far as I can see this remains the same uniform subslice per slice
programming style.
We could play it safe and put all the masks in 64bits in the uAPI.
What do you think?
