* i965/fs: Enumerate logical fb writes argumentsBen Widawsky2015-10-213-21/+29
| | | | | | | | | | | | | | | | | | | Gen9 adds the ability to write out a stencil value, so we need to expand the virtual payload by one. Abstracting this now makes that change easier to read. I was admittedly confused early on about some of the hardcoding. If people believe the resulting code is inferior, I am not super attached to the patch. v2: Remove explicit numbering from the enumeration (Matt). Use a real naming scheme, and reference it in the opcode definition (Curro) Add a missed hardcoded logical position in get_lowered_simd_width (Ben) Add an assertion to make sure the component numbering is correct (Ben) Cc: Matt Turner <[email protected]> Cc: Francisco Jerez <[email protected]> Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | Before the change "tgsi/scan: use properties for clip/cull distance writemasks", the tgsi_shader_info::num_written_clipdistance field was a multiple of four, now it's an accurate count.

* i965: Add a fs_visitor constructor that takes a brw_gs_compile.Kenneth Graunke2015-10-212-3/+39
| | | | | | | | | | | Unlike the vs/wm structs, brw_gs_compile is actually useful: it contains the input VUE map and information about the control data headers. Passing this in allows us to share that code in brw_gs.c, and calculate them before deciding on vec4 vs. scalar mode, as it's independent of that choice.

* i965: Add a brw->scalar_gs flag controlled by INTEL_SCALAR_GS=1.Kenneth Graunke2015-10-213-1/+8
| | | | | | | | | | | This patch introduces a brw->scalar_gs flag, similar to brw->scalar_vs, which controls whether or not to use SIMD8 geometry shaders. For now, we control it via a new environment variable, INTEL_SCALAR_GS. This provides a convenient way to try it out.

| | | | | | | | | | | Geometry shaders have additional header data at the beginning of their output URB entries. Shaders that use EndPrimitive() or multiple streams have a control data header; shaders with a dynamic vertex count have an additional vec4 slot to hold the 32-bit vertex count (and 96 bits of padding).

* i965/gs: Do prog_data setup and other calculations in brw_compile_gsJason Ekstrand2015-10-214-220/+222
| | | | | | | | | | | | | | | | This commit moves the large pile of setup calculations we have to do for geometry shaders out of brw_gs_emit and into brw_compile_gs. This has a couple of nice implications. First, it's less work that the caller of brw_compile_gs has to do. Second, it's consistent with the vertex and fragment stages. Finally, it allows us to put brw_gs_compile back behind the API boundary where it belongs. v2 (Jason Ekstrand): - Pull the changes to use nir info into a separate patch - Put brw_gs_compile into brw_shader.h rather than brw_vec4_gs_visitor.h so that we can use it for scalar GS.

| | | | | | | | | | | | | | | | | When the draw module splits long line loops, the sections are emitted as line strips. But the primitive type wasn't set correctly so each section was being drawn as a loop, introducing extra line segments. To fix this, we pass a new DRAW_LINE_LOOP_AS_STRIP flag to the run() function. The linear/elt_run() functions have to check for this flag and set their primitive type accordingly. No piglit regressions. Fixes piglit's lineloop with -count 4097 or higher.

* vbo: fix GL_LINE_LOOP stray line bugBrian Paul2015-10-203-3/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When long GL_LINE_LOOP primitives don't fit in one vertex buffer they have to be split across buffers. The code to do this was basically correct but drivers had to pay special attention to the _mesa_prim::begin,end flags in order to draw the sections of the line loop properly. Apparently, the only drivers to do this were those using the old 'tnl' module for software vertex processing. Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP primitives so that drivers don't have to worry about the special begin/end flags. The only time a driver will get a GL_LINE_LOOP prim is when the whole thing fits in one vertex buffer. Mostly fixes bug 81174, but not completely. There's another bug somewhere in the src/gallium/auxiliary/draw/ code. If the piglit lineloop test is run with -count 4096, rendering is correct, but with -count 4097 there are stray lines. 4096 is a magic number in the draw code (search for "4096"). Also note that this does not fix long line loops in display lists. The next patch fixes that. v2: fix incorrect -1 in vbo_compute_max_verts(), per Charmaine.
