Author: Iago Toral Quiroga <[email protected]> Date: Wed Jul 3 09:09:11 2019 +0200 v3d: add helpers to emit ldtlb and ldtlbu signals The ldtlbu version will read an implicit uniform with the TLB read specifier and should be used for the first read in a sequence of TLB reads (unless the default configuration is valid, in which case we can use ldtlb). The ldtlb version is used for any subsequent TLB read in the sequence.
