From d26b35ba4478993db85a9a2d3d36b22e941de9f7 Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Wed, 3 Jul 2019 09:09:11 +0200 Subject: 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.
