* glsl: Call check_builtin_array_max_size when redeclaring gl_in.Paul Berry2013-10-241-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | Normally when a built-in array (such as gl_ClipDistance) is redeclared, we call get_variable_being_redeclared() to do the redeclaration, and it in turn calls check_builtin_array_max_size() to make sure that the redeclared array size isn't too large. However when a built-in array is redeclared as part of redeclaring gl_in, we don't call get_variable_being_redeclared() (since the individual built-ins aren't each represented by their own ir_variable anymore). So we need to add an explicit call to check_builtin_array_max_size() to make sure the new array size isn't too large. Note: at the moment this is redundant with a test that's done at link time, so there's no change to piglit results. But the patch that follows will prevent link errors from being reported if gl_PerVertex isn't used, so in order to prevent that patch from causing regressions, we need to add the compile check now. Besides, it's nicer to report this error at compile time anyhow. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Matt Turner <[email protected]>
* mesa: Fix geometry shader program queries.Paul Berry2013-10-241-60/+40
| | | | | | | | | | | | | | | | | | | | | | | | The queries GEOMETRY_VERTICES_OUT, GEOMETRY_INPUT_TYPE, and GEOMETRY_OUTPUT_TYPE (defined by GL 3.2) differ from the corresponding queries in ARB_geometry_shader4 in the following ways: - They use different enum values - They can only be queried; they cannot be set. - Attempting to query them yields INVALID_OPERATION if the program is not linked, or lacks a geometry shader. This patch switches us over from the ARB_geometry_shader4 behaviour to the GL 3.2 behaviour. Fixes piglit test query-gs-prim-types. v2: Improve comment above has_core_gs.

* i965: Reduce gl_MaxGeometryInputComponents to 64.Paul Berry2013-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although in principle there is no hardware limitation that prevents gl_MaxGeometryInputComponents from being set to 128 on Gen7, we have the following limitations in the vec4 compiler back end: - Registers assigned to geometry shader inputs can't be spilled or later re-used for any other purpose. - The last 16 registers are set aside for the "MRF hack", meaning they can only be used to send messages, and not for general purpose computation. - Up to 32 registers may be reserved for push constants, even if there is sufficient register pressure to make this impractical. A shader using 128 geometry input components, and having an input type of triangles_adjacency, would use up: - 1 register for r0 (which holds URB handles and various pieces of control information). - 1 register for gl_PrimitiveID. - 102 registers for geometry shader inputs (17 registers per input vertex, assuming DUAL_INSTANCED dispatch mode and allowing for one register of overhead for gl_Position and gl_PointSize, which are present in the URB map even if they are not used). - Up to 32 registers for push constants. - 16 registers for the "MRF hack". That's a total of 152 registers, which is well over the 128 registers the hardware supports. Fortunately, the GLSL 1.50 spec allows us to reduce gl_MaxGeometryInputComponents to 64. Doing that frees up 48 registers, brining the total down to 104 registers, leaving 24 registers available to do computation. Fixes piglit test spec/glsl-1.50/execution/geometry/max-input-components.

* i965/gs: If a DUAL_OBJECT gs would spill, fall back to DUAL_INSTANCED.Paul Berry2013-10-243-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | This is similar to what we do for 16-wide vs 8-wide fragment shaders. First we try compiling the geometry shader in DUAL_OBJECT mode. If we can't do that without spilling, we fall back on DUAL_INSTANCED mode, which should require less spilling (since it uses an interleaved layout of payload registers). In an ideal world we'd fall back to SINGLE mode, which would allow us to interleave general-purpose registers too (resulting in even less likelihood of spilling). But at the moment, the vec4 generator and visitor classes don't have the infrastructure to interleave general purpose registers, so DUAL_INSTANCED is the best we can do. As a side benefit this paves the way for implementing instanced geometry shaders (which are incompatible with DUAL_OBJECT mode). Since most geometry shaders used in piglit testing are small, DUAL_INSTANCED mode won't get exercised very much in a normal piglit run. To force DUAL_INSTANCED mode to be used for all geometry shaders, set INTEL_DEBUG=nodualobj. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | | | | Geometry shaders that run in "DUAL_INSTANCED" mode store their inputs in vec4's. This means that when compiling gl_PointSize input swizzling (a MOV instruction which uses a geometry shader input as both source and destination), we need to do two things: - Set force_writemask_all to ensure that the MOV happens regardless of which channels are enabled. - Set the source register region to <4;4,1> (instead of <0;4,1> to satisfy register region restrictions. v2: move the source register region fixup to the top of vec4_generator::generate_vec4_instruction(), so that it applies to all instructions rather than just MOV.

* i965/gs: Set force_writemask_all when setting up g0.Paul Berry2013-10-241-2/+3
| | | | | | | | | | | | | | | | | | All geometry shaders begin this instruction: mov(1) g0.2<1>:ud 0x0:ud { align1 } which sets up GRF0 properly for scratch reads and writes. Since this instruction has a SIMD size of 1, it will only have an effect if the first channel is enabled. In practice, the hardware seems to always dispatch geometry shaders with the first channel enabled, but I can't find anything in the docs to guarantee that. So to be on the safe side, set force_writemask_all on the instruction, which guarantees that it will have the desired effect regardless of which channels are enabled.

| | | | | | | | | | | | | | | | | | | | | | d3d10 requires that cube corners are filtered with accurate weights (that is, the weight of the non-existing corner texel should be evenly distributed to the other 3 texels). OpenGL does not require this (but recommends it). This requires us to use different filtering code, since we need per-texel weights which our 2d lerp doesn't (and can't) do. And of course the (now per element) weights need to be adjusted too for it to work. Invoke the new filtering code whenever there's an edge to keep things simpler, as it will work for edges too not just corners but of course it's only needed with corners. More ugly code for not much gain but at least a hacked up cubemap demo shows very nice corners now... Not sure yet if and how this should be configurable... v2: incorporate feedback from Jose, only use special corner filtering code when there's a corner not when there's only an edge (as corner filtering code is slower, though a perf difference was only measureable when always forcing edge code).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i915 has symbols for formerly-shared code that conflict with i965, so we define them away using gen-symbol-redefs.py. Options considered: - This option. Downsides: The symbols in profiling and debugging don't match the source. The symbol list may change in the future and we won't notice without manually running the tool again. - Use objcopy --localize-hidden to automatically demote our symbols to locals. This didn't work on i965 due to c++ weak symbols (which can't be localized), but could work on i915. We could do it on i915 only, but it does produce libtool warnings at link time due to libtool not knowing if the resulting .o file is safe to link (stupid libtool). Plus you end up with different symbols of the same name, which is confusing for debugging too. On the other hand, no future symbol conflicts long term. - Write our own libelf tool that handles c++ weak symbols like we want and apply it to all drivers. All the downsides of above, but applies uniformly across drivers. - Edit the files to just rename all the i915 or i965 symbols that conflict. There are on the order of 100 that have a prefix we used to share, so it would take a bit of typing. Fewest downsides, but still can have conflicts long term. Ultimately, this is the least invasive change at the moment, and we can see if the "more symbol conflicts appear later" thing is a real concern or not.

* i965: Fix glTexImage when packing alignment != cppChad Versace2013-10-241-2/+11
| | | | | | | | | | | | | | | | | | | | | | | Fixes texture corruption of Weston clients on cairo-glesv2 backend. Commit 49ed599 introduced the bug. Corruption occured when glTexSubImage called intel_texsubimage_tiled_memcpy() with: x,y=10,9 w,h=7,7 format=GL_ALPHA(0x1906) type=GL_UNSIGNED_BYTE(0x1401) gl_format=MESA_FORMAT_A8(0x18) packing.alignemnt=4 The function miscalculated the source image's stride as w*cpp=7 without taking into account the packing alignment. The actual stride was 8. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70435 Reported-by: U.

* i965/fs: Only unroll high-accuracy dFdy() from SIMD16 to SIMD8 on gen4 and IVB.Paul Berry2013-10-231-10/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 800610f (i965/fs: Improve accuracy of dFdy() to match dFdx()) I unrolled the high-accuracy dFdy() computation from a single SIMD16 instruction to two SIMD8 instructions because of text I found in the i965 (gen4) PRM saying that instruction compression could not be used in align16 mode. I couldn't find similar text in later hardware docs, and I observed problems trying to use instruction compression on align16 mode on Ivy Bridge, so I assumed that the restriction still applied and the associated documentation had simply been lost. After consultation with the hardware engineers, it turns out this is not the case. In point of fact, the restriction was dropped in gen5, re-introduced in Ivy Bridge, and dropped again in Haswell. The reason I didn't notice this is that in the Ivy Bridge documentation, the restriction was in a different section, and described using different language. Now that we know that the restriction only applies to Gen4 and Ivy Bridge, we can limit the unrolling to those platforms. Tested on gen5, gen6, and gen7 (both Ivy Bridge and Haswell).
