From c59270e2b82abe9bcb0af6a1593b81772f6306d3 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Sun, 19 Sep 2004 08:03:46 +0000 Subject: Add GL_ARB_texture_cube_map support for i830. Most of the code was lifted from the i915 side. i830 will now report version 1.3! Hurrah! With the exception of GL_EXT_texture_compression_s3tc, the i830 driver now supports all the extensions that its Windows counterpart supports. --- src/mesa/drivers/dri/i915/i830_context.c | 2 +- src/mesa/drivers/dri/i915/i830_context.h | 5 +- src/mesa/drivers/dri/i915/i830_reg.h | 1 + src/mesa/drivers/dri/i915/i830_texstate.c | 177 +++++++++++++++++++++++------- src/mesa/drivers/dri/i915/i830_vtbl.c | 6 +- src/mesa/drivers/dri/i915/i915_context.c | 1 - src/mesa/drivers/dri/i915/intel_context.c | 3 +- 7 files changed, 149 insertions(+), 46 deletions(-) (limited to 'src/mesa/drivers') diff --git a/src/mesa/drivers/dri/i915/i830_context.c b/src/mesa/drivers/dri/i915/i830_context.c index 2c81e3de6d..fc63386cbe 100644 --- a/src/mesa/drivers/dri/i915/i830_context.c +++ b/src/mesa/drivers/dri/i915/i830_context.c @@ -99,7 +99,7 @@ GLboolean i830CreateContext( const __GLcontextModes *mesaVis, 4, 11, /* max 2D texture size is 2048x2048 */ 8, /* max 3D texture size is 256^3 */ - 0, /* max CUBE. not supported */ + 10, /* max CUBE texture size is 1024x1024 */ 11, /* max RECT. supported */ 12, GL_FALSE ); diff --git a/src/mesa/drivers/dri/i915/i830_context.h b/src/mesa/drivers/dri/i915/i830_context.h index 48eb704cea..62e20d0a02 100644 --- a/src/mesa/drivers/dri/i915/i830_context.h +++ b/src/mesa/drivers/dri/i915/i830_context.h @@ -89,8 +89,9 @@ #define I830_TEXREG_TM0S2 3 #define I830_TEXREG_TM0S3 4 #define I830_TEXREG_TM0S4 5 -#define I830_TEXREG_MCS 6 /* _3DSTATE_MAP_COORD_SETS */ -#define I830_TEX_SETUP_SIZE 7 +#define I830_TEXREG_MCS 6 /* _3DSTATE_MAP_COORD_SETS */ +#define I830_TEXREG_CUBE 7 /* _3DSTATE_MAP_SUBE */ +#define I830_TEX_SETUP_SIZE 8 #define I830_TEXBLEND_SIZE 12 /* (4 args + op) * 2 + COLOR_FACTOR */ diff --git a/src/mesa/drivers/dri/i915/i830_reg.h b/src/mesa/drivers/dri/i915/i830_reg.h index 69dc333d2c..b931a6b63c 100644 --- a/src/mesa/drivers/dri/i915/i830_reg.h +++ b/src/mesa/drivers/dri/i915/i830_reg.h @@ -637,6 +637,7 @@ #define TM0S2_PITCH_SHIFT 21 #define TM0S2_CUBE_FACE_ENA_SHIFT 15 +#define TM0S2_CUBE_FACE_ENA_MASK (1<<15) #define TM0S2_MAP_FORMAT (1<<14) #define TM0S2_VERTICAL_LINE_STRIDE (1<<13) #define TM0S2_VERITCAL_LINE_STRIDE_OFF (1<<12) diff --git a/src/mesa/drivers/dri/i915/i830_texstate.c b/src/mesa/drivers/dri/i915/i830_texstate.c index 39ba0b8ec3..a393fd1d52 100644 --- a/src/mesa/drivers/dri/i915/i830_texstate.c +++ b/src/mesa/drivers/dri/i915/i830_texstate.c @@ -42,6 +42,19 @@ #include "i830_context.h" #include "i830_reg.h" +static const GLint initial_offsets[6][2] = { {0,0}, + {0,2}, + {1,0}, + {1,2}, + {1,1}, + {1,3} }; + +static const GLint step_offsets[6][2] = { {0,2}, + {0,2}, + {-1,2}, + {-1,2}, + {-1,1}, + {-1,1} }; #define I830_TEX_UNIT_ENABLED(unit) (1<intel.base.lastLevel; numLevels = lastLevel - firstLevel + 1; - /* Pitch would be subject to additional rules if texture memory were - * tiled.
