Author: Eric Anholt <[email protected]> Date: Tue Oct 22 12:38:14 2013 -0700 i965/fs: Stop trying to hack around MRF dep chains on gen7+ LIFO scheduling. This was a hack to avoid choosing to schedule all texturing before consumption of any texture results due to the way dependency chains worked out in the presence of MRFs. On gen7, we don't have MRFs, so the problem doesn't apply, and this was just badly constraining our scheduling. total instructions in shared programs: 1615306 -> 1612534 (-0.17%) instructions in affected programs: 9958 -> 7186 (-27.84%) GAINED: 259 LOST: 9 Reviewed-by: Matt Turner <[email protected]> --- .../drivers/dri/i965/brw_schedule_instructions.cpp | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_schedule_instructions.cpp b/src/mesa/drivers/dri/i965/brw_schedule_instructions.cpp index 99538bd..a1ecfde 100644 --- a/src/mesa/drivers/dri/i965/brw_schedule_instructions.cpp +++ b/src/mesa/drivers/dri/i965/brw_schedule_instructions.cpp @@ -969,7 +969,7 @@ fs_instruction_scheduler::choose_instruction_to_schedule() fs_inst *inst = (fs_inst *)n->inst; chosen = n; - if (inst->regs_written <= 1) + if (v->brw->gen >= 7 || inst->regs_written <= 1) break; } } _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
