From 40bc2748c2781600c748e546160bcc2aab637825 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 5 Mar 2009 17:18:49 -0800 Subject: [PATCH] intel: Add always_flush_batch driconf option for making small batchbuffers. This can improve debugging with INTEL_DEBUG=batch,sync by giving smaller batchbuffers. --- src/mesa/drivers/dri/common/xmlpool/options.h | 10 ++++++++++ src/mesa/drivers/dri/common/xmlpool/t_options.h | 5 +++++ src/mesa/drivers/dri/i965/brw_draw.c | 2 ++ src/mesa/drivers/dri/intel/intel_context.c | 5 +++++ src/mesa/drivers/dri/intel/intel_context.h | 1 + src/mesa/drivers/dri/intel/intel_screen.c | 3 ++- 6 files changed, 25 insertions(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/common/xmlpool/options.h b/src/mesa/drivers/dri/common/xmlpool/options.h index a3cb3747ebc..d76595578c7 100644 --- a/src/mesa/drivers/dri/common/xmlpool/options.h +++ b/src/mesa/drivers/dri/common/xmlpool/options.h @@ -547,6 +547,16 @@ DRI_CONF_OPT_BEGIN(nv_vertex_program,bool,def) \ DRI_CONF_DESC(sv,"Aktivera tillägget GL_NV_vertex_program") \ DRI_CONF_OPT_END +#define DRI_CONF_ALWAYS_FLUSH_BATCH(def) \ +DRI_CONF_OPT_BEGIN(always_flush_batch,bool,def) \ + DRI_CONF_DESC(en,"Enable flushing batchbuffer after each draw call") \ + DRI_CONF_DESC(de,"Enable flushing batchbuffer after each draw call") \ + DRI_CONF_DESC(es,"Enable flushing batchbuffer after each draw call") \ + DRI_CONF_DESC(nl,"Enable flushing batchbuffer after each draw call") \ + DRI_CONF_DESC(fr,"Enable flushing batchbuffer after each draw call") \ + DRI_CONF_DESC(sv,"Enable flushing batchbuffer after each draw call") \ +DRI_CONF_OPT_END + #define DRI_CONF_ALWAYS_FLUSH_CACHE(def) \ DRI_CONF_OPT_BEGIN(always_flush_cache,bool,def) \ DRI_CONF_DESC(en,"Enable flushing GPU caches with each draw call") \ diff --git a/src/mesa/drivers/dri/common/xmlpool/t_options.h b/src/mesa/drivers/dri/common/xmlpool/t_options.h index e489ae9e875..5fd6ec65bf8 100644 --- a/src/mesa/drivers/dri/common/xmlpool/t_options.h +++ b/src/mesa/drivers/dri/common/xmlpool/t_options.h @@ -238,6 +238,11 @@ DRI_CONF_OPT_BEGIN(nv_vertex_program,bool,def) \ DRI_CONF_DESC(en,gettext("Enable extension GL_NV_vertex_program")) \ DRI_CONF_OPT_END +#define DRI_CONF_ALWAYS_FLUSH_BATCH(def) \ +DRI_CONF_OPT_BEGIN(always_flush_batch,bool,def) \ + DRI_CONF_DESC(en,gettext("Enable flushing batchbuffer after each draw call")) \ +DRI_CONF_OPT_END + #define DRI_CONF_ALWAYS_FLUSH_CACHE(def) \ DRI_CONF_OPT_BEGIN(always_flush_cache,bool,def) \ DRI_CONF_DESC(en,gettext("Enable flushing GPU caches with each draw call")) \ diff --git a/src/mesa/drivers/dri/i965/brw_draw.c b/src/mesa/drivers/dri/i965/brw_draw.c index 715236d3dbd..5342622a737 100644 --- a/src/mesa/drivers/dri/i965/brw_draw.c +++ b/src/mesa/drivers/dri/i965/brw_draw.c @@ -411,6 +411,8 @@ static GLboolean brw_try_draw_prims( GLcontext *ctx, retval = GL_TRUE; } + if (intel->always_flush_batch) + intel_batchbuffer_flush(intel->batch); out: UNLOCK_HARDWARE(intel); diff --git a/src/mesa/drivers/dri/intel/intel_context.c b/src/mesa/drivers/dri/intel/intel_context.c index 8c74d946a01..888bb3f18f6 100644 --- a/src/mesa/drivers/dri/intel/intel_context.c +++ b/src/mesa/drivers/dri/intel/intel_context.c @@ -618,6 +618,11 @@ intelInitContext(struct intel_context *intel, intel->no_rast = 1; } + if (driQueryOptionb(&intel->optionCache, "always_flush_batch")) { + fprintf(stderr, "flushing batchbuffer before/after each draw call\n"); + intel->always_flush_batch = 1; + } + if (driQueryOptionb(&intel->optionCache, "always_flush_cache")) { fprintf(stderr, "flushing GPU caches before/after each draw call\n"); intel->always_flush_cache = 1; diff --git a/src/mesa/drivers/dri/intel/intel_context.h b/src/mesa/drivers/dri/intel/intel_context.h index 063102d43a2..e520ecf220d 100644 --- a/src/mesa/drivers/dri/intel/intel_context.h +++ b/src/mesa/drivers/dri/intel/intel_context.h @@ -228,6 +228,7 @@ struct intel_context GLboolean hw_stipple; GLboolean depth_buffer_is_float; GLboolean no_rast; + GLboolean always_flush_batch; GLboolean always_flush_cache; /* 0 - nonconformant, best performance; diff --git a/src/mesa/drivers/dri/intel/intel_screen.c b/src/mesa/drivers/dri/intel/intel_screen.c index 5d8091aaaf1..bccdd55f887 100644 --- a/src/mesa/drivers/dri/intel/intel_screen.c +++ b/src/mesa/drivers/dri/intel/intel_screen.c @@ -71,11 +71,12 @@ PUBLIC const char __driConfigOptions[] = DRI_CONF_SECTION_END DRI_CONF_SECTION_DEBUG DRI_CONF_NO_RAST(false) + DRI_CONF_ALWAYS_FLUSH_BATCH(false) DRI_CONF_ALWAYS_FLUSH_CACHE(false) DRI_CONF_SECTION_END DRI_CONF_END; -const GLuint __driNConfigOptions = 7; +const GLuint __driNConfigOptions = 8; #ifdef USE_NEW_INTERFACE static PFNGLXCREATECONTEXTMODES create_context_modes = NULL; -- 2.30.2
