From: Keith Whitwell Date: Tue, 21 Dec 2004 11:57:03 +0000 (+0000) Subject: Add vsync swapbuffers. This waits on the irq so gears run in this mode X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=314f8e4d9d600f9db95977ebf931a3fb9bb8ce79;p=mesa.git Add vsync swapbuffers. This waits on the irq so gears run in this mode will have a very low cpu utilization (and also a very low framerate). Fix up the pageflipping code. This works now but is totally oblivious to the X server (ie. it works but it's broken). Turned off by a #define. --- diff --git a/src/mesa/drivers/dri/unichrome/via_context.c b/src/mesa/drivers/dri/unichrome/via_context.c index 54b574c60c7..ca106f0ad51 100644 --- a/src/mesa/drivers/dri/unichrome/via_context.c +++ b/src/mesa/drivers/dri/unichrome/via_context.c @@ -62,6 +62,7 @@ #define DRIVER_DATE "20041215" +#include "vblank.h" #include "utils.h" viaContextPtr current_mesa; @@ -230,9 +231,14 @@ calculate_buffer_parameters( viaContextPtr vmesa ) vmesa->depth.size); /*=* John Sheng [2003.5.31] flip *=*/ - if( (vmesa->viaScreen->width == vmesa->driDrawable->w) - && (vmesa->viaScreen->height == vmesa->driDrawable->h) ) { + if( vmesa->viaScreen->width == vmesa->driDrawable->w && + vmesa->viaScreen->height == vmesa->driDrawable->h ) { +#define ALLOW_EXPERIMENTAL_PAGEFLIP 1 +#if ALLOW_EXPERIMENTAL_PAGEFLIP + vmesa->doPageFlip = GL_TRUE; +#else vmesa->doPageFlip = GL_FALSE; +#endif vmesa->currentPage = 0; vmesa->back.pitch = vmesa->front.pitch; } @@ -368,6 +374,13 @@ FreeBuffer(viaContextPtr vmesa) via_free_dma_buffer(vmesa); } +static int +get_ust_nop( int64_t * ust ) +{ + *ust = 1; + return 0; +} + GLboolean viaCreateContext(const __GLcontextModes *mesaVis, __DRIcontextPrivate *driContextPriv, @@ -387,6 +400,12 @@ viaCreateContext(const __GLcontextModes *mesaVis, return GL_FALSE; } if (VIA_DEBUG) fprintf(stderr, "%s - in\n", __FUNCTION__); + + /* Parse configuration files. + */ + driParseConfigFiles (&vmesa->optionCache, &viaScreen->optionCache, + sPriv->myNum, "via"); + current_mesa = vmesa; /* pick back buffer */ if (mesaVis->doubleBufferMode) { @@ -555,6 +574,24 @@ viaCreateContext(const __GLcontextModes *mesaVis, } #endif + /* I don't understand why this isn't working: + */ + vmesa->vblank_flags = + vmesa->viaScreen->irqEnabled ? + driGetDefaultVBlankFlags(&vmesa->optionCache) : VBLANK_FLAG_NO_IRQ; + + /* Hack this up in its place: + */ + vmesa->vblank_flags = getenv("VIA_VSYNC") ?
