From 19064f818a4a5124fe52de1cee79e84372da172b Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Fri, 4 Feb 2005 00:25:41 +0000 Subject: [PATCH] Added an option texture_heaps that allows selecting which texture heaps will be used. Implemented this option in the Savage driver. On my ProSavageDDR uploads to AGP memory are about 1.5 times as fast as uploads to card memory. On non-IGP hardware the difference may be even bigger. Now mplayer -gl is getting really usable. --- src/mesa/drivers/dri/common/xmlpool.h | 17 +++++++++++++++++ src/mesa/drivers/dri/savage/savage_xmesa.c | 20 ++++++++++++++++++-- 2 files changed, 35 insertions(+), 2 deletions(-) diff --git a/src/mesa/drivers/dri/common/xmlpool.h b/src/mesa/drivers/dri/common/xmlpool.h index 789d14f..29b5bf5 100644 --- a/src/mesa/drivers/dri/common/xmlpool.h +++ b/src/mesa/drivers/dri/common/xmlpool.h @@ -293,6 +293,23 @@ DRI_CONF_OPT_BEGIN_V(texture_units,int,def, # min ":" # max ) \ DRI_CONF_DESC(de,"Anzahl der Textureinheiten") \ DRI_CONF_OPT_END +#define DRI_CONF_TEXTURE_HEAPS_ALL 0 +#define DRI_CONF_TEXTURE_HEAPS_CARD 1 +#define DRI_CONF_TEXTURE_HEAPS_GART 2 +#define DRI_CONF_TEXTURE_HEAPS(def) \ +DRI_CONF_OPT_BEGIN_V(texture_heaps,enum,def,"0:2") \ + DRI_CONF_DESC_BEGIN(en,"Used types of texture memory") \ + DRI_CONF_ENUM(0,"All available") \ + DRI_CONF_ENUM(1,"Only card memory (if available)") \ + DRI_CONF_ENUM(2,"Only GART (AGP/PCIE) memory (if available)") \ + DRI_CONF_DESC_END \ + DRI_CONF_DESC_BEGIN(de,"Verwendete Texturspeicherarten") \ + DRI_CONF_ENUM(0,"Alle verfügbaren") \ + DRI_CONF_ENUM(1,"Nur Grafikspeicher (falls vorhanden)") \ + DRI_CONF_ENUM(2,"Nur GART (AGP/PCIE) Speicher (falls vorhanden)") \ + DRI_CONF_DESC_END \ +DRI_CONF_OPT_END + /* Options for features that are not done in hardware by the driver (like GL_ARB_vertex_program On cards where there is no documentation (r200) or on rasterization-only hardware). */ #define DRI_CONF_SECTION_SOFTWARE \ diff --git a/src/mesa/drivers/dri/savage/savage_xmesa.c b/src/mesa/drivers/dri/savage/savage_xmesa.c index 1ce8a4b..9abb558 100644 --- a/src/mesa/drivers/dri/savage/savage_xmesa.c +++ b/src/mesa/drivers/dri/savage/savage_xmesa.c @@ -83,12 +83,13 @@ DRI_CONF_BEGIN DRI_CONF_MAX_TEXTURE_UNITS(2,1,2) SAVAGE_ENABLE_VDMA(true) SAVAGE_ENABLE_FASTPATH(true) + DRI_CONF_TEXTURE_HEAPS(DRI_CONF_TEXTURE_HEAPS_ALL) DRI_CONF_SECTION_END DRI_CONF_SECTION_DEBUG DRI_CONF_NO_RAST(false) DRI_CONF_SECTION_END DRI_CONF_END; -static const GLuint __driNConfigOptions = 7; +static const GLuint __driNConfigOptions = 8; #ifdef USE_NEW_INTERFACE static PFNGLXCREATECONTEXTMODES create_context_modes = NULL; @@ -295,6 +296,7 @@ savageCreateContext( const __GLcontextModes *mesaVis, savageScreenPrivate *savageScreen = (savageScreenPrivate *)sPriv->private; drm_savage_sarea_t *saPriv=(drm_savage_sarea_t *)(((char*)sPriv->pSAREA)+ savageScreen->sarea_priv_offset); + int textureSize[SAVAGE_NR_TEX_HEAPS]; int i; imesa = (savageContextPtr)Xcalloc(sizeof(savageContext), 1); if (!imesa) { @@ -367,11 +369,25 @@ savageCreateContext( const __GLcontextModes *mesaVis, (void) memset( imesa->textureHeaps, 0, sizeof( imesa->textureHeaps ) ); make_empty_list( & imesa->swapped ); + textureSize[SAVAGE_CARD_HEAP] = savageScreen->textureSize[SAVAGE_CARD_HEAP]; + textureSize[SAVAGE_AGP_HEAP] = savageScreen->textureSize[SAVAGE_AGP_HEAP]; imesa->lastTexHeap = savageScreen->texVirtual[SAVAGE_AGP_HEAP] ? 2 : 1; + switch(driQueryOptioni (&imesa->optionCache, "texture_heaps")) { + case DRI_CONF_TEXTURE_HEAPS_CARD: /* only use card memory, if available */ + if (textureSize[SAVAGE_CARD_HEAP]) + imesa->lastTexHeap = 1; + break; + case DRI_CONF_TEXTURE_HEAPS_GART: /* only use gart memory, if available */ + if (imesa->lastTexHeap == 2 && textureSize[SAVAGE_AGP_HEAP]) + textureSize[SAVAGE_CARD_HEAP] = 0; + break; + /*default: Nothing to do, use all available memory. */ + } + for (i = 0; i < imesa->lastTexHeap; i++) { imesa->textureHeaps[i] = driCreateTextureHeap( i, imesa, - savageScreen->textureSize[i], + textureSize[i], 11, /* 2^11 = 2k alignment */ SAVAGE_NR_TEX_REGIONS, (drmTextureRegionPtr)imesa->sarea->texList[i], -- 2.7.4
