2010-09-30gallivm: More comprehensive border usage logic.José Fonseca
2010-09-27llvmpipe: fix swizzling of texture border colorBrian Paul
The pipe_sampler_view's swizzle terms also apply to the texture border color. Simply move the apply_sampler_swizzle() call after we fetch the border color. Fixes many piglit texwrap failures.
2010-09-25gallivm: fix repeat() function for NPOT texturesBrian Paul
The trick of casting the coord to an unsigned value only works for POT textures. Add a bias instead. This fixes a few piglit texwrap failures.
2010-09-25gallivm: fix copy&paste bugRoland Scheidegger
looks like pot_depth should be used, not pot_height (found by accident, not verified)
2010-09-24llvmpipe: make texture border_color dynamic stateBrian Paul
2010-09-24llvmpipe: make min/max lod and lod bias dynamic stateBrian Paul
Before, changing any of these sampler values triggered generation of new JIT code. Added a new flag for the special case of min_lod == max_lod which is hit during auto mipmap generation.
2010-09-21gallivm: fix lp_build_sample_compare()Brian Paul
The old code didn't really make sense. We only need to compare the X channel of the texture (depth) against the texcoord. For (bi)linear sampling we should move the calls to this function and compute the final result as (s1+s2+s3+s4) * 0.25. Someday. This fixes the glean glsl1 shadow2D() tests. See fd.o bug 29307.
2010-09-20gallivm: remove debug codeBrian Paul
2010-09-16gallivm: Start collecting bitwise arithmetic helpers in a new module.José Fonseca
2010-09-16gallivm: make lp_build_sample_nop publicKeith Whitwell
2010-09-15gallivm: Remove unnecessary headers.Vinson Lee
2010-09-15gallivm: expand AoS sampling to cover all filtering modesBrian Paul
...and all texture targets (1D/2D/3D/CUBE).
2010-09-11gallivm: nr_channels is only valid for formats with plain layout.José Fonseca
This is erroneously throwing non plain formats out of the faster AoS sampling path. Doing 8bit interpolation for single channels such as L8 should be no worse than with floating point. But this may need more investigation.
2010-09-11gallivm: Add a new debug flag to warn about performance issues.José Fonseca
2010-08-30gallivm: Compute the 4 texel offsets for linear filtering en ensemble.José Fonseca
2010-08-20gallium: make all checks for PIPE_TEXTURE_2D check for PIPE_TEXTURE_RECT tooLuca Barbieri
Searched for them with: git grep -E '[!=]=.*PIPE_TEXTURE_2D|PIPE_TEXTURE_2D.*[!=]=|case.*PIPE_TEXTURE_2D' Behavior hasn't been changed.
2010-08-14gallivm: Remove unnecessary header.Vinson Lee
2010-08-14u_cpu_detect: remove arch and little_endianLuca Barbieri
This logic duplicates the one in p_config.h, so remove it and adjust the only two places that were using it.
2010-08-11gallivm: Use lp_build_div instead of lp_build_mul + lp_build_rcp.José Fonseca
Single divide, so let lp_build_div decide how to implement this. This will save a multiplication in architectures which don't have a RCP intrinsic.
2010-08-11gallivm: Use unsigned shift in lp_build_minify.José Fonseca
Texture dimensions are unsigned.
2010-08-09gallivm: Always use floating-point operators for floating-point typesnobled
This fixes the assert added in LLVM 2.8: assert(getType()->isIntOrIntVectorTy() && "Tried to create an integer operation on a non-integer type!") But it also fixes some subtle bugs, since we should've been doing this since LLVM 2.6 anyway. Includes a modified patch from steckdenis@yahoo.fr for the FNeg instructions in emit_fetch(); thanks for pointing those out. http://bugs.freedesktop.org/29404 http://bugs.freedesktop.org/29407 Signed-off-by: José Fonseca <jfonseca@vmware.com>
2010-07-07gallivm: restore const qualifierBrian Paul
2010-07-07gallivm: fix cube map LOD computationBrian Paul
First, this undoes commit e503af4baa2c709ae5743bb278b277d3faaba076 so we use iround() in lp_build_nearest_mip_level(). Second, in lp_build_sample_general() we need to check if we're sampling a cube map before anything else. Choose the cube face and then recompute the partial derivatives of (S,T) with respect to the chosen cube face. Before, we were using the directional (S,T,R) derivatives to compute the LOD. Third, work around an apparent bug in LLVM 2.7 where setting the lod variable to a const(0) value results in bad x86 code. See comments in the code.
2010-07-06gallivm: use trunc, not round in lp_build_nearest_mip_level()Brian Paul
Fixes fd.o bug 28036 (piglit fbo-cubemap.c regression)
2010-07-02gallivm: Do 4ubyte AoS texture filtering for any format that can be expressed.José Fonseca
Except if it has only one channel, as it would take the same number of instructions.
2010-07-02gallivm: Move lp_build_rgba8_to_f32_soa() to lp_bld_format_soa.cJosé Fonseca
It will be more useful here.
2010-07-02gallivm: Move gather functions to its own module.José Fonseca
They need to grow, and they provide basic functionality which is not specific to sampling.
2010-06-02gallivm: Make lp_build_sample_wrap_int usage more accurate.José Fonseca
Fixes mesa texwrap demo border with GL_CLAMP.
2010-06-02gallivm: Don't use reciprocate in lp_build_sample_wrap_linear().José Fonseca
Always clamp the scaled coordinates.
2010-06-02gallivm: Avoid fp arithmetic in lp_build_sample_wrap_nearest().José Fonseca
2010-06-02gallivm: Don't use lp_build_sample_wrap_nearest()José Fonseca
Always clamp with scaled coordinates.
2010-05-13llvmpipe: silence uninitialized var warningsBrian Paul
2010-05-12gallivm: rename texel result paramBrian Paul
Be clear that this parameter returns four texel channel results.
2010-05-08gallivm: Fix mipfiltering with negative lod bias.José Fonseca
In particular, don't use the clamped lod to compute level + 1, or lod in [-1, 0] range will actually interpolate with level 1. This makes Mipfilter DCT pass 100%.
2010-05-08gallivm: Centralize SoA swizzling into a single place.José Fonseca
2010-05-04gallivm: Proper implementation of TXL opcode.José Fonseca
2010-05-04gallivm: Fix several glitches introduced in the prev commit.José Fonseca
2010-05-04gallivm: Implement TXD.José Fonseca
2010-04-30llvmpipe: fix out-of-bounds texture samplingBrian Paul
If we're using a wrap mode in which border color sampling is possible it means that texcoords may be outside of the texture image bounds. Fetching the texel may result in a segfault. Use the 'use_border' variable to catch such texcoords and replace the texel offset with zero (which will be in bounds). Fixes segfault in Lightsmark demo, fd.o bug 27877.
2010-04-30llvmpipe: added lp_build_sample_nop() for debuggingBrian Paul
2010-04-29gallivm: add some assertions in special-case sampler codeBrian Paul
2010-04-26llvmpipe: Respect pipe_sampler_view::swizzle_r/g/b/aJosé Fonseca
This allows u_sampler_view_default_dx9_template to do its magic on DX9.
2010-04-24llvmpipe: Implement shader bias.José Fonseca
Fixes glean glsl1 test: texture2D(), with bias.
2010-04-19gallivm: pass 3D texture stride as an arrayBrian Paul
This should have been included with the previous commit.
2010-04-16gallivm: init some vars to silence warningsBrian Paul
2010-04-16gallivm: remove some old stuffBrian Paul
2010-04-06gallivm: Fallback to calling util_format_description::fetch_float for any ↵José Fonseca
format we can't code LLVM IR directly.
2010-03-31util: Generalize lp_format_is_rgba8 into util_format_is_rgba8_variant.José Fonseca
2010-03-15gallivm/llvmpipe: rename some constant building functionsBrian Paul
2010-03-15gallivm: add min_lod==max_lod special-case code in lp_build_lod_selector()Brian Paul
When min_lod==max_lod we don't need to go through all the work of computing the lod from partial derivatives. This is hit by the mipmap generation utility code.
