* swrast: fix uninitialized variable warningBrian Paul2012-01-241-1/+1

* swrast: make rowStride variable signed in put_z32_values()Brian Paul2012-01-241-1/+1
| | | | As with commit aed5c8299fe47b8e1728f8140d069bc89d3fa947
* swrast: remove unused StoreTexel codeBrian Paul2012-01-244-1187/+183
| | | | | No longer needed since we do all rendering to texture with the buffer mapping and pixel packing functions.
* swrast: use Map/UnmapTextureImage() in framebuffer map/unmap codeBrian Paul2012-01-241-15/+13
| | | | | | | When we're actually rendering into a texture, map the texture image instead of the corresponding renderbuffer. Before, we just copied a pointer from the texture image to the renderbuffer. This change will make the code usable by hardware drivers.
* mesa: remove ctx->Driver.Map/UnmapTexture() hooksBrian Paul2012-01-241-3/+0
| | | | No longer used anywhere.
* swrast: move some renderbuffer functions to s_renderbuffer.cBrian Paul2012-01-242-121/+121

* swrast: new swrast_renderbuffer typeBrian Paul2012-01-241-0/+25

|
* swrast: stop using Put/GetRow/Values() in swrast codeBrian Paul2012-01-245-55/+193
| | | | | All color buffer rendering is now done by accessing mapped renderbuffer memory. We're now able to get rid of all the GetRow/PutRow stuff.
* swrast: use gl_renderbuffer::StrideInBytes in depth/stencil codeBrian Paul2012-01-242-6/+6
|
* mesa: use gl_renderbuffer::Map for all depth/stencil accessesBrian Paul2012-01-242-37/+110
| | | | | Instead of using the obsolete gl_renderbuffer::Data field. Color buffer are still accessed through GetRow/PutRow().
* swrast: flush pending rendering before unmapping buffersBrian Paul2012-01-241-2/+3

* swrast: new assertions in _swrast_pixel_address()Brian Paul2012-01-241-0/+8

* swrast: s/Data/Map/ in swrast_texture_imageBrian Paul2012-01-245-14/+14
| | | | To indicate that it points to mapped texture memory.
* swrast: remove gl_renderbuffer::DataType check in DrawPixels()Brian Paul2012-01-241-5/+8
| | | | The field will be going away so update this code.
* swrast: remove gl_renderbuffer::DataType assertionsBrian Paul2012-01-243-3/+0
| | | | This field will go away, so remove some uses of it.
* swrast: make _swrast_get_values(), _swrast_get_row() staticBrian Paul2012-01-242-23/+12
| | | | They were only called from in s_span.c
* swrast: remove dstType param from _swrast_read_rgba_span()Brian Paul2012-01-243-7/+7
| | | | It was always GL_FLOAT.

* swrast: Use fixed-function processing instead _TexEnvProgram for DrawPixelsIan Romanick2012-01-241-2/+21
| | | | | | | | | | | | | | | | | | | | | | | This is a hack to work around drivers such as i965 that: - Set _MaintainTexEnvProgram to generate GLSL IR for fixed-function fragment processing. - Don't call _mesa_ir_link_shader to generate Mesa IR from the GLSL IR. - May use swrast to handle glDrawPixels. Since _mesa_ir_link_shader is never called, there is no Mesa IR to execute. Instead do regular fixed-function processing. Even on platforms that don't need this, the software fixed-function code is much faster than the software shader code. NOTE: This is a candidate for the 8.0 branch.

| | | | | | | | | | | | | | | | | | | | | | When rowstride was negatie, unsigned promotion caused a segfault here: 299│ if (rb->Format == MESA_FORMAT_S8) { 300│ const GLuint rowStride = rb->RowStride; 301│ for (i = 0; i < count; i++) { 302│ if (x[i] >= 0 && y[i] >= 0 && x[i] < w && y[i] < h) { 303├> stencil[i] = *(map + y[i] * rowStride + x[i]); 304│ } 305│ } 306│ } Fixes segfault in oglconform separatestencil-neu(NonPolygon.BothFacesBitmapCoreAPI), though test still fails.

* swrast: fix Z testing of points/lines for 16-bit depth buffersBrian Paul2012-01-071-7/+29
| | | | | | | We were comparing 32-bit Z buffer values against 16-bit fragment values. Need to do scaling like for the 24-bit case. Triangle Z testing was OK since it didn't hit this code path.

* swrast: use memmove() instead of memcpy() in the SHIFT_ARRAY macroBrian Paul2012-01-051-1/+1
| | | | | | | | | | | The src/dst arrays would overlap but dst was less than src so a simple version of memcpy() would do the right thing. But this isn't guaranteed when memcpy() is optimized.
