* llvmpipe: support sRGB framebuffersRoland Scheidegger2013-07-164-18/+111
| | | | | | | | | | | | | | | Just use the new conversion functions to do the work. The way it's plugged in into the blend code is quite hacktastic but follows all the same hacks as used by packed float format already. Only support 4x8bit srgb formats (rgba/rgbx plus swizzle), 24bit formats never worked anyway in the blend code and are thus disabled, and I don't think anyone is interested in L8/L8A8. Would need even more hacks otherwise. Unless I'm missing something, this is the last feature except MSAA needed for OpenGL 3.0, and for OpenGL 3.1 as well I believe. v2: prettify a bit, use separate function for packing.

* r300g/swtcl: fix geometry corruption by uploading indices to a bufferMarek Olšák2013-07-153-45/+31
| | | | | | | | | | | | | The splitting of a draw call into several draw commands was broken, because the split sometimes took place in the middle of a primitive. The splitting was supposed to be dealing with the case when there are more indices than the maximum size of a CS. This commit throws that code away and uses a real index buffer instead. https://bugs.freedesktop.org/show_bug.cgi?id=66558 Cc: [email protected]
* gallivm: (trivial) use constant instead of exp2f() functionRoland Scheidegger2013-07-141-2/+3
| | | | | | | Some lame compilers can't do exp2f() and as far as I can tell they can't do exp2() (with doubles) neither so instead of providing some workaround for that (wouldn't actually be too bad just replace with pow) and since it is used with a constant only just use the precalculated constant.
* ilo: skip 3DSTATE_INDEX_BUFFER when possibleChia-I Wu2013-07-144-59/+77
| | | | | | When only the offset to the index buffer is changed, we can skip the 3DSTATE_INDEX_BUFFER if we always use 0 for the offset, and add (offset / index_size) to Start Vertex Location in 3DPRIMITIVE.
* gallivm: handle srgb-to-linear and linear-to-srgb conversionsRoland Scheidegger2013-07-136-7/+332
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | srgb-to-linear is using 3rd degree polynomial for now which should be _just_ good enough. Reverse is using some rational polynomials and is quite accurate, though not hooked into llvmpipe's blend code yet and hence unused (untested). Using a table might also be an option (for srgb-to-linear especially). This does not enable any new features yet because EXT_texture_srgb was already supported via util_format fallbacks, but performance was lacking probably due to the external function call (the table used by the util_format_srgb code may not be all that much slower on its own). Some performance figures (taken from modified gloss, replaced both base and sphere texture to use GL_SRGB instead of GL_RGB, measured on 1Ghz Sandy Bridge, the numbers aren't terribly accurate): normal gloss, aos, 8-wide: 47 fps normal gloss, aos, 4-wide: 48 fps normal gloss, forced to soa, 8-wide: 48 fps normal gloss, forced to soa, 4-wide: 47 fps patched gloss, old code, soa, 8-wide: 21 fps patched gloss, old code, soa, 4-wide: 24 fps patched gloss, new code, soa, 8-wide: 41 fps patched gloss, new code, soa, 4-wide: 38 fps So there's a performance hit but it seems acceptable, certainly better than using the fallback. Note the new code only works for 4x8bit srgb formats, others (L8/L8A8) will continue to use the old util_format fallback, because I can't be bothered to write code for formats noone uses anyway (as decoding is done as part of lp_build_unpack_rgba_soa which can only handle block type width of 32). Compressed srgb formats should get their own path though eventually (it is going to be expensive in any case, first decompress, then convert). No piglit regressions. v2: use lp_build_polynomial instead of ad-hoc polynomial construction, also since keeping both linear to srgb functions for now make sure both are compiled (since they share quite some code just integrate into the same function). v3: formatting fixes and bugfix in the complicated (disabled) linear-to-srgb path.

* gallivm: better support for fast rsqrtRoland Scheidegger2013-07-132-16/+63
| | | | | | | | | | | | | | | We had to disable fast rsqrt before because it wasn't precise enough etc. However in situations when we know we're not going to need more precision we can still use a fast rsqrt (which can be several times faster than the quite expensive sqrt). Hence introduce a new helper which does exactly that - it is probably not useful calling it in some situations if there's no fast rsqrt available so make it queryable if it's available too. v2: use fast_rsqrt consistently instead of rsqrt_fast, fix indentation, let rsqrt use fast_rsqrt.

* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-1230-105/+103
| | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | The D3D10 spec is very explicit about treatment of denorm floats and the behavior is exactly the same for them as it would be for -0 or +0. This makes our shading code match that behavior, since OpenGL doesn't care and on a few cpu's it's faster (worst case the same). Float16 conversions will likely break but we'll fix them in a follow up commit.
