* mesa: Throw error on glGetActiveUniform inside Begin/End.Eric Anholt2012-05-171-0/+2

* glsl: Improve the local dead code optimization to eliminate unused channels.Eric Anholt2012-05-171-23/+126
| | | | | | | | | | | | | | | Total instructions: 261582 -> 261316 135/2147 programs affected (6.3%) 36752 -> 36486 instructions in affected programs (0.7% reduction) This excludes a tropics shader that now gets 16-wide mode and throws off the numbers. 5 shaders are hurt: two extra MOVs in 4 tropics shaders it looks like because we don't split register names according to independent webs, and one gstreamer shader where it looks like try_rewrite_rhs_to_dst() is falling on its face. This should also help avoid a regression in VSes from idr's ARB programs to GLSL work.
* i965/fs: Do more register coalescing by using the interference graph.Eric Anholt2012-05-172-0/+62
| | | | | | | | | | | | | | By using the live variables code for determining interference, we can handle coalescing in the presence of control flow, which the other register coalescing path couldn't. Total instructions: 207184 -> 206990 74/1246 programs affected (5.9%) 33993 -> 33799 instructions in affected programs (0.6% reduction) There is a newerth shader that loses out, because of some extra MOVs that now get their dead-code nature obscured by coalescing. This should be fixed by doing better at dead code elimination.

* draw,llvmpipe: Avoid named struct types on LLVM 3.0 and later.José Fonseca2012-05-162-30/+6
| | | | | | | | | | | | Starting with LLVM 3.0, named structures are meant not for debugging, but for recursive data types, previously also known as opaque types. The recursive nature of these types leads to several memory management difficulties. Given that we don't actually need recursive types, avoid them altogether. This is an attempt to address fdo bugs 41791 and 44466. The issue is somewhat random so there's no easy way to check how effective this is.

* i965/gen6: Initial implementation of MSAA.Paul Berry2012-05-1523-121/+662
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables MSAA for Gen6, by modifying intel_mipmap_tree to understand multisampled buffers, adapting the rendering pipeline setup to enable multisampled rendering, and adding multisample resolve operations to brw_blorp_blit.cpp. Some preparation work is also included for Gen7, but it is not yet enabled. MSAA support is still fairly preliminary. In particular, the following are not yet supported: - Fully general blits between MSAA and non-MSAA buffers. - Formats other than RGBA8, DEPTH24, and STENCIL8. - Centroid interpolation. - Coverage parameters (glSampleCoverage, GL_SAMPLE_ALPHA_TO_COVERAGE, GL_SAMPLE_ALPHA_TO_ONE, GL_SAMPLE_COVERAGE, GL_SAMPLE_COVERAGE_VALUE, GL_SAMPLE_COVERAGE_INVERT). Fixes piglit tests "EXT_framebuffer_multisample/accuracy" on i965/Gen6. v2: - In intel_alloc_renderbuffer_storage(), quantize the requested number of samples to the next higher sample count supported by the hardware. This ensures that a query of GL_SAMPLES will return the correct value. It also ensures that MSAA is fully disabled on Gen7 for now (since Gen7 MSAA support doesn't work yet). - When reading from a non-MSAA surface, ensure that s_is_zero is true so that we won't try to read from a nonexistent sample.
* i965/gen6+: Add code to perform blits on the render path ("blorp").Paul Berry2012-05-158-27/+1730
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch expands the "blorp" component to be able to perform blits as well as HiZ resolves. The new blitting code is located in brw_blorp_blit.cpp. This includes the necessary fragment shader code to look up pixels in the source buffer (which is configured as a texture) and output them to the destination buffer (which is configured as the render target). Most of the time the fragment shader code is simple and straightforward, since it merely has to apply a coordinate offset, read from the texture, and write to the render target. However, in the case of blitting stencil buffers, things are more complicated, since the GPU stores stencil data using W tiling, and W tiling is not supported for textures or render targets. So, we set up the stencil buffers as Y tiled, and emit fragment shader code that adjusts the coordinates to account for the difference between W and Y tiling. Furthermore, since a rectangular region in W tiling does not necessarily correspond to a rectangular region in Y tiling, we widen the rectangle primitive to the nearest tile boundary and have the fragment shader "kill" any pixels that don't fall inside the actual desired destination rectangle. All of this is a necessary prerequisite for implementing MSAA, since we'll need to be able to blit between multisample color, depth, and stencil buffers and their non-multisampled counterparts, and none of the existing blitting mechanisms support multisampling. In addition, the new blitting code should speed up operations where we previously fell back to software rasterization, such as blitting of stencil buffers. The current fallback sequence is: first we try to do a blit using the hardware blitting engine. If that fails we try to do a blit using the render path. If that also fails then we do the blit using a meta-op (which may or may not fall back to software rasterization). Note that blitting using the render path has some limitations at the moment: it only supports a few formats, and it doesn't support clipping or scissoring. These limitations will be addressed in future patch series. v2: - Add the code that configures the WM program to gen{6,7}_emit_wm_config() and gen7_emit_ps_config() rather than creating separate ...enable() functions. - Call intel_prepare_render before determining which miptrees we are blitting from/to, because it may cause miptrees to be reallocated. - Allow the blit to mirror X and/or Y coordinates. - Disable blorp blits on Gen7 for now, since they aren't working yet.
* i965: Expose surface setup internals for use by blits.Paul Berry2012-05-153-2/+4
| | | | | | | | This patch exposes the functions brw_get_surface_tiling_bits and gen7_set_surface_tiling, so that they can be re-used when setting up surface states in gen6_blorp.cpp and gen7_blorp.cpp. Reviewed-by: Chad Versace <[email protected]>
* i965: split gen{6,7}_blorp_exec functions into manageable chunks.Paul Berry2012-05-153-522/+647
| | | | | | | | | | | | | | | | | This patch splits up the gen6_blorp_exec and gen7_blorp_exec functions, which were very long, into simple component functions. With a few exceptions, there is one function per state packet. This will allow blit functionality to be added without significantly complicating the code. Reviewed-by: Chad Versace <[email protected]> v2: Rename the functions gen{6,7}_emit_wm_disable() to gen{6,7}_emit_wm_config() (since the WM is not actually disabled during HiZ ops; it simply doesn't have a program). Also, on gen7, split out the configration of 3DSTATE_PS to a separate function gen7_emit_ps_config().
* i965: Parameterize HiZ code to prepare for adding blitting.Paul Berry2012-05-157-177/+335
| | | | | | | | | | | | | | | | | | | This patch groups together the parameters used by the HiZ functions into a new data structure, brw_hiz_resolve_params, rather than passing each parameter individually between the HiZ functions. This data structure is a subclass of brw_blorp_params, which represents the parameters of a general-purpose blit or resolve operation. A future patch will add another subclass for blits. In addition, this patch generalizes the (width, height) parameters to a full rect (x0, y0, x1, y1), since blitting operations will need to be able to operate on arbitrary rectangles. Also, it renames several of the HiZ functions to reflect the expanded role they will serve. v2: Rename brw_hiz_resolve_params to brw_hiz_op_params. Move gen{6,7}_blorp_exec() functions back into gen{6,7}_blorp.h. Reviewed-by: Chad Versace <[email protected]>

| | | | | | | | | | | When drawing to a FBO, the viewport wasn't always set correctly. It was fine in the usual case of the viewport dims matching the surface dims but broken otherwise.
