2010-10-08gallivm: special case conversion 4x4f to 1x16ubKeith Whitwell
Nice reduction in the number of operations required for final color output in many shaders.
2010-10-08llvmpipe: avoid overflow in triangle cullingKeith Whitwell
Avoid multiplying fixed-point values. Calculate triangle area in floating point use that for culling. Lift area calculations up a level as we are already doing this in the triangle_both() case. Would like to share the calculated area with attribute interpolation, but the way the code is structured makes this difficult.

2010-10-08gallivm: Implement brilinear filtering.José Fonseca
2010-10-08gallivm: Fix copy'n'paste typo in previous commit.José Fonseca
2010-10-08gallivm: Clamp mipmap level and zero mip weight simultaneously.José Fonseca
2010-10-08gallivm: Use lp_build_ifloor_fract for lod computation.José Fonseca
Forgot this one before.
2010-10-08gallivm: Don't compute the second mipmap level when frac(lod) == 0José Fonseca
2010-10-08gallivm: Simplify lp_build_mipmap_level_sizes' interface.José Fonseca
2010-10-08gallivm: Do not do mipfiltering when magnifying.José Fonseca
If lod < 0, then invariably follows that ilevel0 == ilevel1 == 0.
2010-10-08r600g: Remove unnecessary header.Vinson Lee
2010-10-08r600g: drop width/height per level storage.Dave Airlie
these aren't used anywhere, so just waste memory.
2010-10-07i965: Normalize cubemap coordinates like is done in the Mesa IR path.Eric Anholt
Fixes glsl-fs-texturecube-2-*
2010-10-07i965: Disable emitting if () statements on gen6 until we really fix them.Eric Anholt
2010-10-08r600g: add some RG texture format support.Dave Airlie
2010-10-07gles2: Add GL_EXT_texture_format_BGRA8888 supportKristian Høgsberg
2010-10-07gallivm: Vectorize the rho computation.José Fonseca
2010-10-07r600g: fix Z export enable bits.Dave Airlie
we should be checking output array not input to decide. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-07r600g: use format from the sampler view not from the texture.Dave Airlie
we want to use the format from the sampler view which isn't always the same as the texture format when creating sampler views.
2010-10-07r600g: fix evergreen interpolation setupAndre Maasikas
interp data is stored in gpr0 so first interp overwrote it and subsequent ones got wrong values reserve register 0 so it's not used for attribs. alternative is to interpolate attrib0 last (reverse, as r600c does)
2010-10-07st/vega: Fix version check in context creation.Chia-I Wu
This fixes a regression since 4531356817ec8383ac35932903773de67af92e37.
2010-10-07targets/egl: Fix linking with libdrm.Chia-I Wu
2010-10-06i965: Fix gen6 pointsize handling to match pre-gen6.Eric Anholt
Fixes point-line-no-cull. Bug #30532
2010-10-06i965: Don't assume that WPOS is always provided on gen6 in the new FS.Eric Anholt
We sensibly only provide it if the FS asks for it. We could actually skip WPOS unless the FS needed WPOS.zw, but that's something for later. Fixes: glsl-texture2d and probably many others.
2010-10-06i965: Add support for gl_FrontFacing on gen6.Eric Anholt
Fixes glsl1-gl_FrontFacing var (2) with new FS.
2010-10-06i965: Refactor gl_FrontFacing setup out of general variable setup.Eric Anholt
2010-10-06i965: Gen6's sampler messages are the same as Ironlake.Eric Anholt
This should fix texturing in the new FS backend.
2010-10-06i965: Don't do 1/w multiplication in new FS for gen6Eric Anholt
Not needed now that we're doing barycentric.
2010-10-06i965: Add some clarification of the WECtrl field.Eric Anholt
2010-10-06i965: Fix botch in the header_present case in the new FS.Eric Anholt
I only set it on the color_regions == 0 case, missing the important case, causing GPU hangs on pre-gen6.
2010-10-06llvmpipe: Cleanup depth-stencil clears.José Fonseca
Only cosmetic changes. No actual practical difference.
2010-10-06util: Cleanup util_pack_z_stencil and friends.José Fonseca
- Handle PIPE_FORMAT_Z32_FLOAT packing correctly. - In the integer version z shouldn't be passed as as double. - Make it clear that the integer versions should only be used for masks. - Make integer type sizes explicit (uint32_t for now, although uint64_t will be necessary later to encode f32_s8_x24).
2010-10-06gallivm: Compute lod as integer whenever possible.José Fonseca
More accurate/faster results for PIPE_TEX_MIPFILTER_NEAREST. Less FP <-> SI conversion overall.
2010-10-06gallivm: Only apply min/max_lod when necessary.José Fonseca
2010-10-06gallivm: don't apply zero lod_biasKeith Whitwell
2010-10-06gallivm: Combined ifloor & fract helper.José Fonseca
The only way to ensure we don't do redundant FP <-> SI conversions.
2010-10-06gallivm: Fast implementation of iround(log2(x))José Fonseca
Not tested yet, but should be correct.
2010-10-06gallivm: Use a faster (and less accurate) log2 in lod computation.José Fonseca
2010-10-06gallivm: Take the type signedness in consideration in round/ceil/floor.José Fonseca
2010-10-06i965: Fix up IF/ELSE/ENDIF for gen6.Eric Anholt
The jump delta is now in the part of the instruction where the destination fields used to be, and the src args are ignored (or not, for the new non-predicated IF that we don't use yet).
2010-10-06i965: Gen6 no longer has the IFF instruction; always use IF.Eric Anholt
2010-10-06i965: Add back gen6 headerless FB writes to the new FS backend.Eric Anholt
It's not that hard to detect when we need the header.
2010-10-06r600g: fix dirty state handlingJerome Glisse
Avoid having object ending up in dead list of dirty object. Signed-off-by: Jerome Glisse <jglisse@redhat.com>
2010-10-06i965: Also do constant propagation for the second operand of CMP.Eric Anholt
We could do the first operand as well by flipping the comparison, but this covered several CMPs in code I was looking at.
2010-10-06i965: Enable the constant propagation code.Eric Anholt
A debug disable had slipped in.
2010-10-06r600g: avoid segfault due to unintialized list pointerJerome Glisse
Signed-off-by: Jerome Glisse <jglisse@redhat.com>
2010-10-06llvmpipe: Fix sprite coord perspective interpolation of Q.José Fonseca
Q coordinate's coefficients also need to be multiplied by w, otherwise it will have 1/w, causing problems with TXP.
2010-10-06llvmpipe: Fix perspective interpolation for point sprites.José Fonseca
Once a fragment is generated with LP_INTERP_PERSPECTIVE set for an input, it will do a divide by w for that input. Therefore it's not OK to treat LP_INTERP_PERSPECTIVE as LP_INTERP_LINEAR or vice-versa, even if the attribute is known to not vary. A better strategy would be to take the primitive in consideration when generating the fragment shader key, and therefore avoid the per-fragment perspective divide.
2010-10-06llvmpipe: Dump a few missing shader key flags.José Fonseca
2010-10-06llvmpipe: make debug_fs_variant respect variant->nr_samplersKeith Whitwell
