* Merge remote branch 'origin/master' into glsl2Eric Anholt2010-07-26296-7800/+12406
|\ | | | | | | | | | | | | | | | | | | | | This pulls in multiple i965 driver fixes which will help ensure better testing coverage during development, and also gets past the conflicts of the src/mesa/shader -> src/mesa/program move. Conflicts: src/mesa/Makefile src/mesa/main/shaderapi.c src/mesa/main/shaderobj.h
| * i965: Fix reversed naming of the operations in compute-to-mrf optimization.Eric Anholt2010-07-263-6/+11
| | | | | | | | | | Also fix up comments, so that the difference between the two passes is clarified.
| * i965: Clean up a few magic numbers to use brw_defines.h defs.Eric Anholt2010-07-263-18/+20
| |
| * i965: Use MIN2, MAX2 instead of rolling our own.Eric Anholt2010-07-261-15/+12
| |
| * i965: Fold the "is arithmetic" bit of 965 opcodes into the opcode list.Eric Anholt2010-07-261-50/+26
| |
| * i965: Remove some duped register size/count definitionsEric Anholt2010-07-262-34/+26
| |
| * i965: Move the GRF-to-MRF optimizations to brw_optimize.c.Eric Anholt2010-07-263-619/+618
| |
| * i965: Improve (i.e. remove) some grf-to-mrf unnecessary movesBenjamin Segovia2010-07-261-2/+626
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several routines directly analyze the grf-to-mrf moves from the Gen binary code. When it is possible, the mov is removed and the message register is directly written in the arithmetic instruction Also redundant mrf-to-grf moves are removed (frequently for example, when sampling many textures with the same uv) Code was tested with piglit, warsow and nexuiz on an Ironlake machine. No regression was found there Note that the optimizations are *deactivated* on Gen4 and Gen6 since I did test them properly yet. No reason there are bugs but who knows The optimizations are currently done in branch free programs *only*. Considering branches is more complicated and there are actually two paths: one for branch free programs and one for programs with branches Also some other optimizations should be done during the emission itself but considering that some code is shader between vertex shaders (AOS) and pixel shaders (SOA) and that we may have branches or not, it is pretty hard to both factorize the code and have one good set of strategies
| * i965: Allow VS MOVs to use immediate constants.Eric Anholt2010-07-261-0/+1
| | | | | | | | | | Clarifies program assembly, and with a little tweak to always use constant_map, we could cut down on constant buffer payload.
| * mesa: Fix Cygwin build with llvm enabled.Vinson Lee2010-07-231-1/+1
| | | | | | | | | | On Cygwin locale_t in not available but 'llvm-config --cppflags' adds the compiler flag -D_GNU_SOURCE to the build.
| * gallium: Fix build with llvm installed in non-standard locationChristopher James Halse Rogers2010-07-231-0/+7
| | | | | | | | | | | | | | | | | | | | The es1, es2 and gl state trackers include draw_pipe.h, which includes the llvm headers if MESA_LLVM is true, so we also need to add the llvm seachpaths. Similarly, gallivm and other gallium drivers need LLVM_CFLAGS to build when enabled. Also fix xorg drivers, they didn't include LDFLAGS.
| * st/mesa: get rid of unneeded ureg_writemask()Brian Paul2010-07-231-3/+2
| |
| * st/mesa: fix bug in emit_adjusted_wpos()Brian Paul2010-07-231-2/+5
| | | | | | | | | | | | | | | | | | If we bias x,y we still need to pass through z,w in case the shader reads gl_FragCoord.z or .w. Fixes fd.o bug 29183 (piglit glsl-bug-22603). NOTE: This is a candidate for the 7.8 branch.
| * i965: Cleanly fail programs with unsupported array access.Eric Anholt2010-07-231-1/+28
| | | | | | | | | | This should be more useful for developers and for bug triaging than just generating wrong code.
| * i965: Add support for VS relative addressing of temporary arrays.Eric Anholt2010-07-231-2/+49
| | | | | | | | Fixes glsl-vs-arrays. Bug #27388.
| * glsl: remove invalid _mesa_problem() callBrian Paul2010-07-221-0/+2
| | | | | | | | Fixes fd.o bug 29206.
| * i965: Respect VS/VP point size result when enabled.Eric Anholt2010-07-221-3/+4
| | | | | | | | Fixes glsl-vs-point-size.
| * i965: Fix the disasm output for da16 src widths.Eric Anholt2010-07-221-1/+1
| | | | | | | | | | | | This has confused me twice now. It's a fixed width of 4 (usually a region description of <4,4,1>), not 1. If it was 1, we'd have been skipping all over register space.
| * i965: Avoid extra MOV in VS indirect register reads.Eric Anholt2010-07-221-15/+16
| |
| * i965: Fix up VS temporary array access for fixed index offset != 0.Eric Anholt2010-07-221-1/+1
| |
| * r600: Flip point sprite coordinates when rendering to an FBO.Henri Verbeet2010-07-221-1/+3
| | | | | | | | This supersedes http://lists.freedesktop.org/archives/mesa-dev/2010-July/001442.html.
| * i965: In the VS, multiply the address reg by the appropriate register size.Eric Anholt2010-07-211-27/+14
| | | | | | | | | | | | | | | | | | | | | | | | The ARL value is increments of vec4 in the register file. But PROGRAM_TEMPORARY or PROGRAM_INPUT are stored as vec4s interleaved between the two verts being executed (thus a vec8 each), compared to PROGRAM_STATE_VAR being packed vec4s. Fixes: glsl-vs-arrays-2 glsl-vs-mov-after-deref (without regressing glsl-vs-arrays-3)
| * i965: Clean up brw_dp_READ_4_vs() now that it has fewer options to support.Eric Anholt2010-07-213-52/+31
| |
| * i965: Support relative addressed VS constant reads using the appropriate msg.Eric Anholt2010-07-213-31/+66
| | | | | | | | | | The previous support was overly complicated by trying to use the same 1-OWORD message for both offsets.
| * i965: Fix the DP read msg_control definitions other than plain OWORD.Eric Anholt2010-07-211-6/+16
| |
| * i965: Clean up dead code from the VS get_constant/get_reladdr_constant split.Eric Anholt2010-07-211-3/+1
| |
| * i956: Set the execution size correctly for scratch space writes.Eric Anholt2010-07-211-2/+2
| | | | | | | | | | | | | | | | Otherwise, the second half isn't written, and we end up reading back black. Fixes the remaining junk drawn in glsl-max-varyings, and will likely help with a number of large real-world shaders.
| * i965: Set the GEM domain flags for the scratch space.Eric Anholt2010-07-211-1/+1
| | | | | | | | | | | | They go into the render cache, so while we don't care about their contents after execution, failing to note them could cause the writes to be flushed over important buffer contents later.
| * i965: Use the pretty define for 4-oword DP reads.Eric Anholt2010-07-211-1/+1
| |
| * i965: Set the send commit bit on register spills as required pre-gen6.Eric Anholt2010-07-211-9/+32
| | | | | | | | Otherwise, the subsequent read may not get the written value.
| * i965: Add disasm for dataport reads (register unspilling).Eric Anholt2010-07-211-1/+22
| |
| * st/mesa: implement depth clampMarek Olšák2010-07-212-0/+6
| |
| * Add missing initialization of inOutFlags pointer.Carl Worth2010-07-211-1/+1
| | | | | | | | | | | | This quiets a compiler warning, (and ensures a segmentation fault rather than memory corruption if this variable is written through before being initialized elsewhere).
| * i965: Remove an unused variable.Carl Worth2010-07-211-1/+0
| | | | | | | | To quiet a compiler warning.
| * Regenerate program/lex.yy.cCarl Worth2010-07-211-179/+206
| | | | | | | | Based on the two recent changes to program_lexer.l.
| * Avoid more warnings in flex-generated code.Carl Worth2010-07-211-0/+7
| | | | | | | | | | | | | | | | | | | | This avoids two "function defined but not used" warnings. For the yyinput function we define YY_NO_INPUT which tells flex to simply not generate this function. For unput, we add a call to this function, but inside a while(0) so that it will quiet the warning without actually changing any functionality.
| * Avoid warnings in flex-generated code.Carl Worth2010-07-211-0/+6
| | | | | | | | | | | | Add declarations for two functions generated in the flex ouput. It would be nicer if flex simply declared these generated functions as static, but for now we can at least avoid the warning this way.
| * radeon: Remove unnecessary header.Vinson Lee2010-07-201-1/+0
| |
| * st/mesa: implement and advertise GL_ARB_draw_elements_base_vertexMarek Olšák2010-07-202-3/+5
| | | | | | | | Signed-off-by: Brian Paul <[email protected]>
| * st/mesa: implement depth texture modesMarek Olšák2010-07-201-11/+85
| |
| * mesa: call ctx->Driver.ChooseTextureFormat() only when necessary.Brian Paul2010-07-203-51/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When defining mipmap level 'L' and level L-1 exists and the new level's internalFormat matches level L-1's internalFormat, then use the same hw format. Otherwise, do the regular ctx->Driver.ChooseTextureFormat() call. This avoids a problem where we end up choosing different hw formats for different mipmap levels depending on how the levels are defined (glTexImage vs. glCopyTexImage vs. glGenerateMipmap, etc). The root problem is the ChooseTextureFormat() implementation in some drivers uses the user's glTexImage format/type parameters in the choosing heuristic. Later mipmap levels might be generated with different calls (ex: glCopyTexImage()) so we don't always have format/type info and the driver may choose a different format. For more background info see the July 2010 mesa-dev thread "Bug in _mesa_meta_GenerateMipmap"
| * glx: Remove support for MESA_swap_frame_usageKristian Høgsberg2010-07-197-42/+0
| | | | | | | | | | The extension never worked, the implementation returns GLX_BAD_CONTEXT when enabling the frame tracking.
| * glx: Drop support for GLX_MESA_allocate_memoryKristian Høgsberg2010-07-194-154/+0
| | | | | | | | Only r200 implemented it.
| * i965: Mostly fix glsl-max-varyings.Eric Anholt2010-07-191-10/+20
| | | | | | | | | | | | | | | | There was confusion on both the size of message we can send, and on what the URB destination offset means. The remaining problems appear to be due to spilling of regs in the fragment shader being broken.
| * i965: Clean up message register setup in emit_vertex_write().Eric Anholt2010-07-191-7/+7
| |
| * i965: Reduce repeated calculation of the attribute-offset-in-VUE.Eric Anholt2010-07-194-24/+19
| | | | | | | | | | | | This cleans up some chipset dependency sprinkled around, and fixes a potential overflow of the attribute offset array for many vertex results.
| * i965: Clarify the nr_regs calculation in brw_clip.cEric Anholt2010-07-191-3/+8
| |
| * i965: Don't set up VUE space for the disabled user clip distances on gen6.Eric Anholt2010-07-192-8/+14
| |
| * mesa: remove restart.c from buildBrian Paul2010-07-192-2/+0
| |
| * st/mesa: fix FRAMEBUFFER_UNSUPPORTED with the D24S8 formatMarek Olšák2010-07-191-7/+19
| | | | | | | | | | | | Fixes FDO bug #29116. NOTE: this is a candidate for the 7.8 branch
