From a22aee5ad1154918aff77af5102fecd2aa39a631 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 10 Sep 2016 12:53:37 -0400 Subject: [PATCH] gm107/ir: AL2P writes to a predicate register We have to force it to write to predicate 7 (aka PT) in order for it not to mess up another predicate. Unclear what would be returned in the predicate, perhaps an error code for out-of-bounds requests. Blob doesn't seem to check it.
