From 589ec337f0080893baba996201cf65bb6e1a2fec Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Sun, 4 Oct 2009 13:04:08 +0100 Subject: llvmpipe: Autogenerate lp_tile_soa.c from u_format.csv. This is just a temporary change until we code generate the tile read/write functions in runtime. The new code avoids an extra memcpy that exists in u_tile.c functions, from which lp_tile_soa.c was originally based. This achieves up to 5% improvement, particularly in frames with little geometry overlap. --- src/gallium/drivers/llvmpipe/.gitignore | 1 + src/gallium/drivers/llvmpipe/Makefile | 3 + src/gallium/drivers/llvmpipe/SConscript | 7 + src/gallium/drivers/llvmpipe/lp_tile_cache.c | 77 +-- src/gallium/drivers/llvmpipe/lp_tile_soa.c | 931 --------------------------- src/gallium/drivers/llvmpipe/lp_tile_soa.h | 16 +- src/gallium/drivers/llvmpipe/lp_tile_soa.py | 278 ++++++++ 7 files changed, 339 insertions(+), 974 deletions(-) create mode 100644 src/gallium/drivers/llvmpipe/.gitignore delete mode 100644 src/gallium/drivers/llvmpipe/lp_tile_soa.c create mode 100644 src/gallium/drivers/llvmpipe/lp_tile_soa.py (limited to 'src/gallium/drivers') diff --git a/src/gallium/drivers/llvmpipe/.gitignore b/src/gallium/drivers/llvmpipe/.gitignore new file mode 100644 index 00000000000..257b72d7b2b --- /dev/null +++ b/src/gallium/drivers/llvmpipe/.gitignore @@ -0,0 +1 @@ +lp_tile_soa.c diff --git a/src/gallium/drivers/llvmpipe/Makefile b/src/gallium/drivers/llvmpipe/Makefile index cd7b6356d28..21aff1967a1 100644 --- a/src/gallium/drivers/llvmpipe/Makefile +++ b/src/gallium/drivers/llvmpipe/Makefile @@ -55,3 +55,6 @@ C_SOURCES = \ lp_tile_soa.c include ../../Makefile.template + +lp_tile_soa.c: lp_tile_soa.py ../../auxiliary/util/u_format_parse.py ../../auxiliary/util/u_format_access.py ../../auxiliary/util/u_format.csv + python lp_tile_soa.py ../../auxiliary/util/u_format.csv > $@ diff --git a/src/gallium/drivers/llvmpipe/SConscript b/src/gallium/drivers/llvmpipe/SConscript index f4a9a3b22e2..13cd465838a 100644 --- a/src/gallium/drivers/llvmpipe/SConscript +++ b/src/gallium/drivers/llvmpipe/SConscript @@ -9,6 +9,13 @@ if not env.has_key('LLVM_VERSION'): env.Tool('udis86') +env.CodeGenerate( + target = 'lp_tile_soa.c', + script = 'lp_tile_soa.py', + source = ['#src/gallium/auxiliary/util/u_format.csv'], + command = 'python $SCRIPT $SOURCE > $TARGET' +) + llvmpipe = env.ConvenienceLibrary( target = 'llvmpipe', source = [ diff --git a/src/gallium/drivers/llvmpipe/lp_tile_cache.c b/src/gallium/drivers/llvmpipe/lp_tile_cache.c index 2ac8cb5c82d..68d3fa3282d 100644 --- a/src/gallium/drivers/llvmpipe/lp_tile_cache.c +++ b/src/gallium/drivers/llvmpipe/lp_tile_cache.c @@ -241,42 +241,34 @@ lp_flush_tile_cache(struct llvmpipe_tile_cache *tc) for (x = 0;
