2014-04-28util: Fix cross-compiles between endiannessesRichard Sandiford2-32/+46
The old python code used sys.is_big_endian to select between little-endian and big-endian formats, which meant that the build and host endiannesses needed to be the same. This patch instead generates both big- and little- endian layouts, using PIPE_ARCH_BIG_ENDIAN to select between them.

2014-04-25gallium/util: use ui[4] instead of ui in union util_colorRoland Scheidegger2-20/+20
util_color often merely represents a collection of bytes, however it is inconvenient if those bytes can only be accessed as floats/doubles for int formats exceeding 32bits. (Note that since rgba8 formats use one uint, not 4 bytes, hence the byte and short member were left as is.)

warning. Now that _debug_assert_fail() has the noreturn attribute, it is better that execution truly never returns. Not just for sake of silencing the warning, but because the code at the return IP address may be invalid or lead to inconsistent results. This removes support for the GALLIUM_ABORT_ON_ASSERT debugging environment variable, but between the usefulness of GALLIUM_ABORT_ON_ASSERT and better static code analysis I think better static code analysis wins.

2014-04-10gallium/u_gen_mipmap: rewrite using pipe->blit (v2)Marek Olšák2-493/+70
This replaces u_gen_mipmap with an extremely simple implementation based on pipe->blit. st/mesa is also cleaned up. Pros: - less code - correct mipmap generation for NPOT 3D textures (u_blitter uses a better formula) - queries are not affected by mipmap generation if drivers disable them v2: add "first_layer", "last_layer" parameters, drop "face" v2.1: add format v2.2: document the format parameter

2014-03-21gallium: add b5g6r5 srgb formatRoland Scheidegger3-4/+19
GL generally doesn't seem to allow srgb formats with less (or more) than 8 bit for the rgb channels, though some hw could easily do it (typically for formats with up to 10 bits for the rgb channels, at least for formats with less than 8 bits support is likely widespread even). While it may be true there aren't really any benefits for such formats, we need for it for d3d, though luckily only for b5g6r5_srgb it seems. So add this format along with the util code for conversion - since that util code is heavily tuned for 8bit srgb this isn't really all that well optimized and rounding doesn't seem right but at least it should give some halfway meaningful results.

2014-03-07gallium: allow setting of the internal stream output offsetZack Rusin3-6/+11
D3D10 allows setting of the internal offset of a buffer, which is in general only incremented via actual stream output writes. By allowing setting of the internal offset draw_auto is capable of rendering from buffers which have not been actually streamed out to. Our interface didn't allow. This change functionally shouldn't make any difference to OpenGL where instead of an append_bitmask you just get a real array where -1 means append (like in D3D) and 0 means do not append.

Some formats can't be handled - in particular cannot handle ints/uints formats, which lack the pack_rgba_float/unpack_rgba_float functions. Instead of trying to call these (and crash) return an error (I'm not sure yet if we should try to translate such formats too here might not make much sense). v2: suggested by Jose, use separate checks for pack/unpack of rgba_8unorm and rgba_float functions (right now if one exists the other should as well).

2014-01-13st/mesa: bind NULL colorbuffers as specified by glDrawBuffersMarek Olšák2-0/+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 <brianp@vmware.com>

2013-12-12gallium: allow choosing which colorbuffers to clearMarek Olšák1-3/+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.
2013-12-03gallium/util: implement layered framebuffer clear in u_blitterMarek Olšák6-25/+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.
