* i965/gen6: Improve glReadPixels() performance by blitting to a linear temp.Eric Anholt2011-11-032-8/+81
| | | | | | | The readpixels microbenchmark in mesa-demos goes from 47Mpix/sec at 1000x1000 to 450Mpix/sec. The 10x10 sizes stay about the same. Reviewed-by: Brian Paul <[email protected]>

* intel: Don't force a batchbuffer flush in readpixels.Eric Anholt2011-11-033-3/+12
| | | | | | | | Renderbuffer mapping handles flushing the batchbuffer if required, so all we need to do is make sure any pending rendering has reached the batchbuffer. Reviewed-by: Brian Paul <[email protected]>

| | | | | | | There doesn't appear to be any particular reason for this -- it's not like the width is changing between the deref and the use. Reviewed-by: Brian Paul <[email protected]>

* swrast: Drop the remaining GetRow-based glReadPixels() fast-path.Eric Anholt2011-11-031-90/+0
| | | | | | | | | In all of piglit, only two tests hit it (reading to RGBA float, where GetRow would drop floats into place from R, RG, or RGB). Mostly this is because _ColorReadClamp has been causing transferOps to always be set, skipping any fast-paths anyway. Reviewed-by: Brian Paul <[email protected]>
* swrast: Remove dead _swrast_read_depth_span_uint().Eric Anholt2011-11-032-88/+0
| | | | | | | All the code using it is converted to MapRenderbuffer and the core unpack functions. Reviewed-by: Brian Paul <[email protected]>
* swrast: Convert color glReadPixels slow path to using MapRenderbuffer.Eric Anholt2011-11-031-72/+33
| | | | | | | | | | | | | | | | | | | This may be a bit slower than before because we're switching from per-format compiled loops in GetRow to _mesa_unpack_rgba_block_unpack's loop around a callback to unpack a pixel. The solution there would be to make _mesa_unpack_rgba_block fold the span loop into the format handlers. (On the other hand, function call overhead will hardly matter if MapRenderbuffer means the driver gets the data into cacheable memory instead of uncached). The adjust_colors code should no longer be required, since the unpack function does the 565 to float conversion in a single pass instead of converting it (poorly) through 8888 as apparently happened in the past.

* swrast: MapRenderbuffer in separate depth/stencil readpixels fastpathEric Anholt2011-11-032-21/+59
| | | | | | | | | | | | This introduces two new span helper functions we'll want to use in several places as we move to MapRenderbuffer, which pull out integer depth and stencil values from a renderbuffer mapping based on the renderbuffer format. v2: Use format_unpack helper for stencil read. v3: Clean up comment after conversion to format_unpack.

* swrast: Make the packed depth/stencil read fastpath use MapRenderbuffer.Eric Anholt2011-11-033-29/+94
| | | | | | | | | | | This also makes it handle 24/8 vs 8/24, fixing piglit depthstencil-default_fb-readpixels-24_8 on i965.

* swrast: Directly map the stencil buffer in read_stencil_pixels.Eric Anholt2011-11-033-4/+74
| | | | | | | | | | | This avoids going through the wrapper that has to rewrite the data for packed depth/stencil. This isn't done in _swrast_read_stencil_span because we don't want to map/unmap for each span. v2: Move the unpack code to format_unpack.c. v3: Fix signed/unsigned comparison.

| | | | Fixes Coverity uninitialized scalar variable defect.
* i965: Fix constant propagation into 32-bit integer MUL.Paul Berry2011-11-032-2/+15
| | | | | | | | | | | | | | | i965's MUL instruction can't take an immediate value as its first argument. So normally, if constant propagation wants to propagate a constant into the first argument of a MUL instruction, it swaps the order of the two arguments. This doesn't work for 32-bit integer (and unsigned integer) multiplies, because the MUL operation is asymmetric in that case (it multiplies 16 bits of one operand by 32 bits of the other). Fixes piglit tests {vs,fs}-multiply-const-{ivec4,uvec4}. Reviewed-by: Eric Anholt <[email protected]>
* svga: use the draw-module's sprite stage depending on FS inputsBrian Paul2011-11-031-1/+23
| | | | | | | | | | | If we're drawing sprites and the fragment shader needs both auto- generated texcoords and user-defined varying vars we need to use this fallback path. The reason is when we enable auto texcoord generation, it gets enabled for all texcoord sets. And that clobbers the user-defined varying vars. Reviewed-by: José Fonseca <[email protected]>
* svga: pass fragment shader to draw moduleBrian Paul2011-11-033-0/+12
| | | | | | | | | If we use the draw-module for wide point/line/etc drawing we'll need a fragment shader too (like we pass in the vertex shader). This fixes sprite point rendering when forcing the swtnl path. Reviewed-by: José Fonseca <[email protected]>
* svga: implement generic variable index remappingBrian Paul2011-11-039-21/+165
| | | | | | | | | | | | | | | | | | | | | | | | | The state tracker may generate shaders that use generic vs outputs / fs inputs like: DCL IN[0], GENERIC[0] DCL IN[1], GENERIC[10] DCL IN[2], GENERIC[11] This patch remaps 0, 10, 11 to small integers like 1, 2, 3 so that we stay inside the SVGA3D limit (8). The remapping is done to both the vertex shader outputs and the fragment shader inputs. The same mapping must be used for a vs/fs pair. Note that 'union svga_compile_key' is now 'struct svga_compile_key' because we needed to add the register remapping table. The change in size isn't really significant though (it's not a search key). Also, add assertions when building up SVGA3D src/dst registers to we don't try to store too large of value for the bitfield size. Reviewed-by: José Fonseca <[email protected]>

* linker: Check that initializers for global variables matchIan Romanick2011-11-037-7/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires tracking a couple extra fields in ir_variable: * A flag to indicate that a variable had an initializer. * For non-const variables, a field to track the constant value of the variable's initializer. For variables non-constant initalizers, ir_variable::has_initializer will be true, but ir_variable::constant_initializer will be NULL. The linker can use the values of these fields to check adherence to the GLSL 4.20 rules for shared global variables: "If a shared global has multiple initializers, the initializers must all be constant expressions, and they must all have the same value. Otherwise, a link error will result. (A shared global having only one initializer does not require that initializer to be a constant expression.)" Previous to 4.20 the GLSL spec simply said that initializers must have the same value. In this case of non-constant initializers, this was impossible to determine. As a result, no vendor actually implemented that behavior. The 4.20 behavior matches the behavior of NVIDIA's shipping implementations. NOTE: This is candidate for the 7.11 branch.
