07:14 dj-death: someone understand what the value computed by gl_SubGroupLtMaskARB means?
07:14 dj-death: The nir_intrinsics.py has : subgroup_lt_mask bit index < subgroup_invocation
07:16 dj-death: each lane computes a 0/1 based on its on... what? < subgroup_invocation
07:45 glehmann: for each invocation, it contains the bit mask of invocations with a smaller invocation_id
07:47 glehmann: so 0 for invocation 0, 0x1 for 1, 0x3 for 2, 0x7 for 3, ... 0x7fff'ffff for invocation 31
07:48 dj-death: glehmann: thanks
