From 3e7f8005db3e8f5f493ab83c1438bb6cf8c840b5 Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Tue, 30 Sep 2014 15:06:23 -0700 Subject: [PATCH] i965/fs: Emit compressed BFI2 instructions on Gen > 7. IVB had a restriction that prevented us from emitting compressed three-source instructions, and although that was lifted on Haswell, Haswell had a new restriction that said BFI instructions specifically couldn't be compressed. --- src/mesa/drivers/dri/i965/brw_fs_generator.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/brw_fs_generator.cpp b/src/mesa/drivers/dri/i965/brw_fs_generator.cpp index 145e0ea44f8..e20d3ccb8a4 100644 --- a/src/mesa/drivers/dri/i965/brw_fs_generator.cpp +++ b/src/mesa/drivers/dri/i965/brw_fs_generator.cpp @@ -1729,7 +1729,7 @@ fs_generator::generate_code(const cfg_t *cfg) * Otherwise we would be able to emit compressed instructions like we * do for the other three-source instructions. */ - if (dispatch_width == 16) { + if (dispatch_width == 16 && brw->gen < 8) { brw_set_default_compression_control(p, BRW_COMPRESSION_NONE); brw_BFI2(p, firsthalf(dst), firsthalf(src[0]), firsthalf(src[1]), firsthalf(src[2])); brw_set_default_compression_control(p, BRW_COMPRESSION_2NDHALF); -- 2.30.2
