From: Damien Lespiau <[email protected]>
We exit early if has_aliasing_ppgtt is 0, so towards the end of the
function has_aliasing_ppgtt can only be 1.
Also:
if (foo)
return 1;
else
return 0;
when foo is already a bool is really just:
return foo;
v2:
- Simplify more using the fact that i915.enable_execlists requires that
GEN >= 8. (Chris)
