From 47e974354715702a75ad2f1ee803b72cbd8cc9f1 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sun, 1 Sep 2019 21:57:05 -0500 Subject: intel/fs: Fix FB write inst groups This commit does two things. First, it simplifies the way we compute the FB write group bit. There's no reason to use a ternary because inst->group / 16 can only be 0 or 1. Second, it fixes an order-of- operations bug where the ternary wasn't selecting between (1 << 11) and 0 but between (1 << 11) and 0 | brw_dp_write_desc(...).
