From 070b2c2efc415f459e9c32415b401609acded565 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 10 Oct 2014 13:56:45 +0200 Subject: [PATCH] vc4: Use the fnv1 hash function instead of gallium util's crc32. Improves simulated norast performance on a little benchmark by 13.4012% +/- 2.08459% (n=13). --- src/gallium/drivers/vc4/vc4_program.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/vc4/vc4_program.c b/src/gallium/drivers/vc4/vc4_program.c index b22426cf9aa..690f644b61a 100644 --- a/src/gallium/drivers/vc4/vc4_program.c +++ b/src/gallium/drivers/vc4/vc4_program.c @@ -31,6 +31,7 @@ #include "util/u_pack_color.h" #include "util/format_srgb.h" #include "util/ralloc.h" +#include "util/hash_table.h" #include "tgsi/tgsi_dump.h" #include "tgsi/tgsi_info.h" #include "tgsi/tgsi_lowering.h" @@ -1886,13 +1887,13 @@ vc4_update_compiled_shaders(struct vc4_context *vc4, uint8_t prim_mode) static unsigned fs_cache_hash(void *key) { - return util_hash_crc32(key, sizeof(struct vc4_fs_key)); + return _mesa_hash_data(key, sizeof(struct vc4_fs_key)); } static unsigned vs_cache_hash(void *key) { - return util_hash_crc32(key, sizeof(struct vc4_vs_key)); + return _mesa_hash_data(key, sizeof(struct vc4_vs_key)); } static int -- 2.30.2
