* gallium/util: easy fixes for NULL colorbuffersMarek Olšák2014-01-132-1/+7

* st/mesa: bind NULL colorbuffers as specified by glDrawBuffersMarek Olšák2014-01-132-0/+25
| | | | | | | | | | | | | | | | | | | | An example why it is required: Let's say there's a fragment shader writing to gl_FragData[0..1]. The user calls: glDrawBuffers(2, {GL_NONE, GL_COLOR_ATTACHMENT0}); That means gl_FragData[0] is unused and gl_FragData[1] is written to GL_COLOR_ATTACHMENT0. st/mesa was skipping the GL_NONE draw buffer, therefore gl_FragData[0] was written to GL_COLOR_ATTACHMENT0, which was wrong. This commit fixes it, but drivers must also be fixed not to crash when binding NULL colorbuffers. There is also a new set of piglit tests for this. The MSAA state also had to be fixed not to crash when reading fb->cbufs[0]. Reviewed-by: Brian Paul <[email protected]>

* gallium: allow choosing which colorbuffers to clearMarek Olšák2013-12-121-3/+4
| | | | | | | | | | | | | | Required for glClearBuffer, which only clears one colorbuffer attachment. Example: If the first colorbuffer is float and the second one is int: pipe->clear(pipe, PIPE_CLEAR_COLOR0, float_clear_color, ...); pipe->clear(pipe, PIPE_CLEAR_COLOR1, int_clear_color, ...); This doesn't need any driver changes yet, because all drivers just use: if (flags & PIPE_CLEAR_COLOR) .. The drivers which support GL 3.0 will have to implement it properly though.
* gallium/util: implement layered framebuffer clear in u_blitterMarek Olšák2013-12-036-25/+106
| | | | | | | | | | | | | All bound layers (from first_layer to last_layer) should be cleared. This uses a vertex shader which outputs gl_Layer = gl_InstanceID, so each instance goes to a different layer. By rendering a quad and setting the instance count to the number of layers, it will trivially clear all layers. This requires AMD_vertex_shader_layer (or PIPE_CAP_TGSI_VS_LAYER), which only radeonsi supports at the moment. r600 could do this too. Standard DX11 hardware will have to use a geometry shader though, which has higher overhead.

* u_gen_mipmap: Use untampered cubemap texture coords when generating mipmaps.José Fonseca2013-11-205-6/+19
| | | | | | | | | | | | | | | | | | | It's not necessary to scale down cubemap texture coords when generating mipmaps: we are doing a 2x minification therefore it's guaranteed that the texture coords will always be at least 1 texel away of the edges. Scaling down can actually be harmful, as it may cause artefacts when generating mipmaps with nearest filtering. Sample points will lie exactly in the middle each 2x2 texels, so the scaling factor was causing different texels to be take on each quadrant of the cube face. This is apparent with a 1x1 checkerboard pattern in the base mipmap level: instead of next mipmap level receiving a constant color throughout the face, it will have different colors for each quadrant of the face. The behaviour for blits is left untouched for now, but the cubemap texture coord scaling hack should be reconsidered eventually. Reviewed-by: Brian Paul <[email protected]>

* util: try much harder to set DAZ flagRoland Scheidegger2013-08-083-1/+31
| | | | | | | | | | | | | | | | | | While so far this only causes some harmless test failures, there's lots more cpus with DAZ. All 64bit capable ones can do it (particularly relevant for AMD cpus as they supported sse3 very very late) but if really necessary we can check support for that for real with some more magic. (In fact just about ANY cpu with sse2 can support DAZ, I believe the only exception are first gen P4 (Willamette) and from those only early steppings which can't do it it's almost like intel forgot to add it... - a real pity though docs say you can't just try to set it as they will throw a GPF.) While this was meant to address https://bugs.freedesktop.org/show_bug.cgi?id=67672 it does not fix it. Most likely the tests need fixing as I don't think there's any guarantee about denorm handling in the reference math library functions if the flags aren't set to standard values. Nevertheless enabling DAZ on all cpus which can do it should be the right thing to do. Reviewed-by: Jose Fonseca <[email protected]>

Also fix up another inaccurate pow factor (this time in the python code) - wondering where the couple one bit errors came from :-(.

* util: don't flush overflowing values to infinity in half-float conversionRoland Scheidegger2013-07-272-9/+17
| | | | | | | | | | | | | | | | | | I am not able to find _any_ rounding behavior specified for OpenGL for float to half-float conversions. However, it is specified for fp11/fp10 which suggests round to next finite value but round-to-zero would also be allowed, but finite values must not be flushed to infinity in either case. Hence I believe it makes sense to do the same for half-floats too. We could probably also use round-to-zero consistently, which is in fact required by d3d10 (but it doesn't seem to matter much). Does not match the mesa core function doing the same though (which is saying it was built to match intel gpus which I don't believe for a second as it would cause failures in d3d10, moreover the PRM (for ivy bridge, not listed in older manuals) while not specifying rounding behavior clearly states finite numbers are never flushed to infinity).
