From 16f8c823898fd71a3545457eacd2dc31ddeb3592 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 11 Nov 2010 09:30:16 -0800 Subject: i965: Move payload reg setup to compile, not lookup time. Payload reg setup on gen6 depends more on the dispatch width as well as the uses_depth, computes_depth, and other flags. That's something we want to decide at compile time, not at cache lookup. As a bonus, the fragment shader program cache lookup should be cheaper now that there's less to compute for the hash key. --- src/mesa/drivers/dri/i965/brw_wm.h | 27 ++++++++++++++------------- 1 file changed, 14 insertions(+), 13 deletions(-) (limited to 'src/mesa/drivers/dri/i965/brw_wm.h') diff --git a/src/mesa/drivers/dri/i965/brw_wm.h b/src/mesa/drivers/dri/i965/brw_wm.h index 2ca685784f..d34566a4bd 100644 --- a/src/mesa/drivers/dri/i965/brw_wm.h +++ b/src/mesa/drivers/dri/i965/brw_wm.h @@ -59,16 +59,9 @@ #define AA_ALWAYS 2 struct brw_wm_prog_key { - GLuint source_depth_reg:3; - GLuint source_w_reg:3; - GLuint aa_dest_stencil_reg:3; - GLuint dest_depth_reg:3; - GLuint nr_payload_regs:4; - GLuint computes_depth:1; /* could be derived from program string */ - GLuint source_depth_to_render_target:1; + GLuint stats_wm:1; GLuint flat_shade:1; GLuint linear_color:1; /**< linear interpolation vs perspective interp */ - GLuint runtime_check_aads_emit:1; GLuint nr_color_regions:5; GLuint render_to_fbo:1; @@ -81,6 +74,8 @@ struct brw_wm_prog_key { GLushort drawable_height; GLbitfield64 vp_outputs_written; + GLuint iz_lookup; + GLuint line_aa; GLuint program_string_id:32; }; @@ -204,6 +199,15 @@ struct brw_wm_compile { PASS2_DONE } state; + GLuint source_depth_reg:3; + GLuint source_w_reg:3; + GLuint aa_dest_stencil_reg:3; + GLuint dest_depth_reg:3; + GLuint nr_payload_regs:4; + GLuint computes_depth:1; /* could be derived from program string */ + GLuint source_depth_to_render_target:1; + GLuint runtime_check_aads_emit:1; + /* Initial pass - translate fp instructions to fp instructions, * simplifying and adding instructions for interpolation and * framebuffer writes. @@ -306,11 +310,8 @@ void brw_wm_print_insn( struct brw_wm_compile *c, void brw_wm_print_program( struct brw_wm_compile *c, const char *stage ); -void brw_wm_lookup_iz( struct intel_context *intel, - GLuint line_aa, - GLuint lookup, - GLboolean ps_uses_depth, - struct brw_wm_prog_key *key ); +void brw_wm_lookup_iz(struct intel_context *intel, + struct brw_wm_compile *c); GLboolean brw_wm_is_glsl(const struct gl_fragment_program *fp); void brw_wm_glsl_emit(struct brw_context *brw, struct brw_wm_compile *c); -- cgit v1.2.3
