From 18894a5e5a55e110aa0b2a64d5446c4ffcef1365 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 25 Apr 2019 12:29:55 -0700 Subject: v3d: Fix detection of the last ldtmu before a new TMU op. We were looking at the start instruction, instead of scanning through the list of following instructions to find any more ldtmus. --- src/broadcom/compiler/vir_register_allocate.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/broadcom/compiler') diff --git a/src/broadcom/compiler/vir_register_allocate.c b/src/broadcom/compiler/vir_register_allocate.c index 32b9a8abe8e..1b58bb9c420 100644 --- a/src/broadcom/compiler/vir_register_allocate.c +++ b/src/broadcom/compiler/vir_register_allocate.c @@ -36,11 +36,11 @@ static bool is_last_ldtmu(struct qinst *inst, struct qblock *block) { - list_for_each_entry_from(struct qinst, scan_inst, inst, + list_for_each_entry_from(struct qinst, scan_inst, inst->link.next, &block->instructions, link) { - if (inst->qpu.sig.ldtmu) + if (scan_inst->qpu.sig.ldtmu) return false; - if (v3d_qpu_writes_tmu(&inst->qpu)) + if (v3d_qpu_writes_tmu(&scan_inst->qpu)) return true; } -- cgit v1.2.3
