From 7ce814b25f8c216c7897904cbce7f570112e60ef Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Fri, 19 Jun 2009 20:00:55 +0200 Subject: [PATCH] radeons: use dp4 for position invariant vertex programs Fixes #22181. R200 requires this since DP4 is used in hw tnl mode. R300 prefers it (should be faster due to no instruction dependencies), but both methods should be correct (when sw tcl is used though, MUL/MAD might be faster). Probably doesn't make much difference for R100 since vertex progs are executed in software anyway, but let's just keep it the same there too. --- src/mesa/drivers/dri/r200/r200_context.c | 2 ++ src/mesa/drivers/dri/r300/r300_context.c | 2 ++ src/mesa/drivers/dri/radeon/radeon_context.c | 2 ++ 3 files changed, 6 insertions(+) diff --git a/src/mesa/drivers/dri/r200/r200_context.c b/src/mesa/drivers/dri/r200/r200_context.c index 8924849d082..241390cef79 100644 --- a/src/mesa/drivers/dri/r200/r200_context.c +++ b/src/mesa/drivers/dri/r200/r200_context.c @@ -388,6 +388,8 @@ GLboolean r200CreateContext( const __GLcontextModes *glVisual, ctx->Const.MaxDrawBuffers = 1; + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext( ctx ); diff --git a/src/mesa/drivers/dri/r300/r300_context.c b/src/mesa/drivers/dri/r300/r300_context.c index 76881e49282..7aa8075aa70 100644 --- a/src/mesa/drivers/dri/r300/r300_context.c +++ b/src/mesa/drivers/dri/r300/r300_context.c @@ -410,6 +410,8 @@ GLboolean r300CreateContext(const __GLcontextModes * glVisual, r300InitConstValues(ctx, screen); + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext(ctx); diff --git a/src/mesa/drivers/dri/radeon/radeon_context.c b/src/mesa/drivers/dri/radeon/radeon_context.c index 8f780c443c9..229b4387cae 100644 --- a/src/mesa/drivers/dri/radeon/radeon_context.c +++ b/src/mesa/drivers/dri/radeon/radeon_context.c @@ -316,6 +316,8 @@ r100CreateContext( const __GLcontextModes *glVisual, ctx->Const.MaxDrawBuffers = 1; + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext( ctx ); -- 2.30.2
