Driver should override as needed. --- diff --git a/src/mesa/main/config.h b/src/mesa/main/config.h index f8109ec755c..5e9a4f89394 100644 --- a/src/mesa/main/config.h +++ b/src/mesa/main/config.h @@ -176,13 +176,11 @@ /** For GL_ARB_fragment_program */ /*@{*/ #define MAX_FRAGMENT_PROGRAM_ADDRESS_REGS 0 -#define MAX_FRAGMENT_PROGRAM_ALU_INSTRUCTIONS 48 -#define MAX_FRAGMENT_PROGRAM_TEX_INSTRUCTIONS 24 -#define MAX_FRAGMENT_PROGRAM_TEX_INDIRECTIONS 4 /*@}*/ /** For any program target/extension */ /*@{*/ +#define MAX_PROGRAM_INSTRUCTIONS (16 * 1024) #define MAX_PROGRAM_LOCAL_PARAMS 128 /* KW: power of two */ #define MAX_PROGRAM_ENV_PARAMS 128 #define MAX_PROGRAM_MATRICES 8 diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index ed3faecf0db..144da613843 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -819,11 +819,33 @@ _mesa_init_current(GLcontext *ctx) /** - * Init vertex/fragment program native limits from logical limits. + * Init vertex/fragment program limits. + * Important: drivers should override these with actual limits. */ static void -init_natives(struct gl_program_constants *prog) +init_program_limits(GLenum type, struct gl_program_constants *prog) { + prog->MaxInstructions = MAX_PROGRAM_INSTRUCTIONS; + prog->MaxAluInstructions = MAX_PROGRAM_INSTRUCTIONS; + prog->MaxTexInstructions = MAX_PROGRAM_INSTRUCTIONS; + prog->MaxTexIndirections = MAX_PROGRAM_INSTRUCTIONS; + prog->MaxTemps = MAX_PROGRAM_TEMPS; + prog->MaxEnvParams = MAX_PROGRAM_ENV_PARAMS; + prog->MaxLocalParams = MAX_PROGRAM_LOCAL_PARAMS; + prog->MaxUniformComponents = 4 * MAX_UNIFORMS; + + if (type == GL_VERTEX_PROGRAM_ARB) { + prog->MaxParameters = MAX_NV_VERTEX_PROGRAM_PARAMS; + prog->MaxAttribs = MAX_NV_VERTEX_PROGRAM_INPUTS; + prog->MaxAddressRegs = MAX_VERTEX_PROGRAM_ADDRESS_REGS; + } + else { + prog->MaxParameters = MAX_NV_FRAGMENT_PROGRAM_PARAMS; + prog->MaxAttribs = MAX_NV_FRAGMENT_PROGRAM_INPUTS; + prog->MaxAddressRegs = MAX_FRAGMENT_PROGRAM_ADDRESS_REGS; + } + + /* copy the above limits to init native limits */ prog->MaxNativeInstructions = prog->MaxInstructions; prog->MaxNativeAluInstructions = prog->MaxAluInstructions; prog->MaxNativeTexInstructions = prog->MaxTexInstructions; @@ -885,33 +907,10 @@ _mesa_init_constants(GLcontext *ctx) ctx->Const.MaxViewportWidth = MAX_WIDTH; ctx->Const.MaxViewportHeight = MAX_HEIGHT; #if FEATURE_ARB_vertex_program - ctx->Const.VertexProgram.MaxInstructions = MAX_NV_VERTEX_PROGRAM_INSTRUCTIONS; - ctx->Const.VertexProgram.MaxAluInstructions = 0; - ctx->Const.VertexProgram.MaxTexInstructions = 0; - ctx->Const.VertexProgram.MaxTexIndirections = 0; - ctx->Const.VertexProgram.MaxAttribs = MAX_NV_VERTEX_PROGRAM_INPUTS; - ctx->Const.VertexProgram.MaxTemps = MAX_PROGRAM_TEMPS; - ctx->Const.VertexProgram.MaxParameters = MAX_NV_VERTEX_PROGRAM_PARAMS; - ctx->Const.VertexProgram.MaxLocalParams = MAX_PROGRAM_LOCAL_PARAMS; - ctx->Const.VertexProgram.MaxEnvParams = MAX_PROGRAM_ENV_PARAMS; - ctx->Const.VertexProgram.MaxAddressRegs = MAX_VERTEX_PROGRAM_ADDRESS_REGS; - ctx->Const.VertexProgram.MaxUniformComponents = 4 * MAX_UNIFORMS; - init_natives(&ctx->Const.VertexProgram); + init_program_limits(GL_VERTEX_PROGRAM_ARB, &ctx->Const.VertexProgram); #endif - #if FEATURE_ARB_fragment_program - ctx->Const.FragmentProgram.MaxInstructions = MAX_NV_FRAGMENT_PROGRAM_INSTRUCTIONS; - ctx->Const.FragmentProgram.MaxAluInstructions = MAX_FRAGMENT_PROGRAM_ALU_INSTRUCTIONS; - ctx->Const.FragmentProgram.MaxTexInstructions = MAX_FRAGMENT_PROGRAM_TEX_INSTRUCTIONS; - ctx->Const.FragmentProgram.MaxTexIndirections = MAX_FRAGMENT_PROGRAM_TEX_INDIRECTIONS; - ctx->Const.FragmentProgram.MaxAttribs = MAX_NV_FRAGMENT_PROGRAM_INPUTS; - ctx->Const.FragmentProgram.MaxTemps = MAX_PROGRAM_TEMPS; - ctx->Const.FragmentProgram.MaxParameters = MAX_NV_FRAGMENT_PROGRAM_PARAMS; - ctx->Const.FragmentProgram.MaxLocalParams = MAX_PROGRAM_LOCAL_PARAMS; - ctx->Const.FragmentProgram.MaxEnvParams = MAX_PROGRAM_ENV_PARAMS; - ctx->Const.FragmentProgram.MaxAddressRegs = MAX_FRAGMENT_PROGRAM_ADDRESS_REGS; - ctx->Const.FragmentProgram.MaxUniformComponents = 4 * MAX_UNIFORMS; - init_natives(&ctx->Const.FragmentProgram); + init_program_limits(GL_FRAGMENT_PROGRAM_ARB, &ctx->Const.FragmentProgram); #endif ctx->Const.MaxProgramMatrices = MAX_PROGRAM_MATRICES; ctx->Const.MaxProgramMatrixStackDepth = MAX_PROGRAM_MATRIX_STACK_DEPTH;
