2010-12-04intel: Add an env var override to execute for a different GPU revision.Eric Anholt
Sometimes I'm on the train and want to just read what's generated under INTEL_DEBUG=vs,wm for some code on another generation. Or, for the next gen enablement we'll want to dump aub files before we have the actual hardware. This will let us do that.
2010-12-04st/vega: Fix pipe blend state for various blend modes.Chia-I Wu
rgb_src_factor and rgb_dst_factor should be PIPE_BLENDFACTOR_ONE for VG_BLEND_SRC_IN and VG_BLEND_DST_IN respectively. VG_BLEND_SRC_OVER can be supported only when the fb has no alpha channel. VG_BLEND_DST_OVER and VG_BLEND_ADDITIVE have to be supported with a shader. Note that Porter-Duff blending rules assume premultiplied alpha.
2010-12-04st/vega: Add blend shaders for all blend modes.Chia-I Wu
2010-12-04st/vega: Fix VG_BLEND_MULTIPLY.Chia-I Wu
TEMP[1].w will be needed for OUT.w just below. Use TEMP[0] to store the intermediate value.

2010-12-04st/vega: Blending should use premultiplied alpha.Chia-I Wu
Convert color values to and back from premultiplied form for blending. Finally the rendering result of the blend demo looks much closer to that of the reference implementation.
2010-12-04st/vega: Add support for per-channel alpha.Chia-I Wu
Drawing an image in VG_DRAW_IMAGE_STENCIL mode produces per-channel alpha for use in blending. Add a new shader stage to produce and save it in TEMP[1]. For other modes that do not need per-channel alpha, the stage does MOV TEMP[1], TEMP[0].wwww
2010-12-04st/vega: Move masking after blending.Chia-I Wu
Masking should happen after blending. The shader is not entirely correct, but leave it as is for now.
2010-12-04st/vega: Refactor blend shaders.Chia-I Wu
Add a helper function, blend_generic, that supports all blend modes and per-channel alpha. Make other blend generators a wrapper to it. Both the old and new code expects premultiplied colors, yet the input is non-premultiplied. Per-channel alpha is also not used for stencil image. They still need to be fixed.

2010-12-03mesa: make glGet*(GL_NONE) generate GL_INVALID_ENUMBrian Paul
In find_value() check if we've hit the 0th/invalid entry before checking if the pname matches. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=31987 NOTE: This is a candidate for the 7.9 branch.

2010-12-03mesa: consolidate some compiler -D flagsBrian Paul
-D__STDC_CONSTANT_MACROS and -D__STDC_LIMIT_MACROS are only needed for LLVM build.

.. instead of calling r500_index_bias_supported(..) every draw call.

2010-12-03mesa: return GL_FRAMEBUFFER_DEFAULT as FBO attachment typeBrian Paul
If querying the default/window-system FBO's attachment type, return GL_FRAMEBUFFER_DEFAULT (per the GL_ARB_framebuffer_object spec). See http://bugs.freedesktop.org/show_bug.cgi?id=31947 NOTE: This is a candidate for the 7.9 branch.
2010-12-03mesa: fix GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME queryBrian Paul
Return 0 instead of generating an error. See http://bugs.freedesktop.org/show_bug.cgi?id=30993 Note that piglit fbo-getframebufferattachmentparameter-01 still does not pass. But Mesa behaves the same as the NVIDIA driver in this case. Perhaps the test is incorrect. NOTE: This is a candidate for the 7.9 branch.

2010-12-03st/vega: Add a missing break.Chia-I Wu
2010-12-03st/vega: Move vertex transformation to shader.Chia-I Wu
It was done in path-to-polygon conversion. That meant that the results were invalidated when the transformation was modified, and CPU had to recreate the vertex buffer with new vertices. It could be a performance hit for apps that animate.

2010-12-03mesa, st/mesa: fix gl_FragCoord with FBOs in GalliumMarek Olšák
gl_FragCoord.y needs to be flipped upside down if a FBO is bound. This fixes: - piglit/fbo-fragcoord - https://bugs.freedesktop.org/show_bug.cgi?id=29420 Here I add a new program state STATE_FB_WPOS_Y_TRANSFORM, which is set based on whether a FBO is bound. The state contains a pair of transformations. It can be either (XY=identity, ZW=transformY) if a FBO is bound, or (XY=transformY, ZW=identity) otherwise, where identity = (1, 0), transformY = (-1, height-1). A classic driver (or st/mesa) may, based on some other state, choose whether to use XY or ZW, thus negate the conditional "if (is a FBO bound) ...". The reason for this is that a Gallium driver is allowed to only support WPOS relative to either the lower left or the upper left corner, so we must flip the Y axis accordingly again. (the "invert" parameter in emit_wpos_inversion) NOTE: This is a candidate for the 7.9 branch. Signed-off-by: Marek Olšák <maraeo@gmail.com> Signed-off-by: Brian Paul <brianp@vmware.com>
2010-12-03r300g: implement simple transfer_inline_write for buffersMarek Olšák
r600g might need something like that as well. This speeds up constant buffer upload a bit.
2010-12-03r300g: use internal BO handle for add_buffer and write_relocMarek Olšák
Small perf improvement in ipers. radeon_drm_get_cs_handle is exactly what this commit tries to avoid in every write_reloc.

The field was redundant. Use the gallivm->builder value instead.
