From 4e8bbed926729fe280701412d85aff64ab79856c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Sun, 5 Jul 2015 16:10:54 +0200 Subject: [PATCH] cso: drop inefficient checking for redundant sampler state changes Drivers can do this better, because they can skip redundant state changes at per-slot granularity. --- src/gallium/auxiliary/cso_cache/cso_context.c | 28 ++----------------- 1 file changed, 2 insertions(+), 26 deletions(-) diff --git a/src/gallium/auxiliary/cso_cache/cso_context.c b/src/gallium/auxiliary/cso_cache/cso_context.c index 1705175d660..969a9a41650 100644 --- a/src/gallium/auxiliary/cso_cache/cso_context.c +++ b/src/gallium/auxiliary/cso_cache/cso_context.c @@ -56,11 +56,6 @@ */ struct sampler_info { - struct { - void *samplers[PIPE_MAX_SAMPLERS]; - unsigned nr_samplers; - } hw; - void *samplers[PIPE_MAX_SAMPLERS]; unsigned nr_samplers; @@ -1187,27 +1182,8 @@ single_sampler_done(struct cso_context *ctx, unsigned shader_stage) } info->nr_samplers = i; - - if (info->hw.nr_samplers != info->nr_samplers || - memcmp(info->hw.samplers, - info->samplers, - info->nr_samplers * sizeof(void *)) != 0) - { - memcpy(info->hw.samplers, - info->samplers, - info->nr_samplers * sizeof(void *)); - - /* set remaining slots/pointers to null */ - for (i = info->nr_samplers; i < info->hw.nr_samplers; i++) - info->samplers[i] = NULL; - - ctx->pipe->bind_sampler_states(ctx->pipe, shader_stage, 0, - MAX2(info->nr_samplers, - info->hw.nr_samplers), - info->samplers); - - info->hw.nr_samplers = info->nr_samplers; - } + ctx->pipe->bind_sampler_states(ctx->pipe, shader_stage, 0, i, + info->samplers); } void -- 2.30.2
