* draw: nuke the interp parameter from vertex_infoRoland Scheidegger2016-01-071-13/+12
| | | | | | | | | | | | | draw emit couldn't care less what the interpolation mode is... This somehow looked like it would matter, all drivers more or less dutifully filled that in correctly. But this is only used for emit, if draw needs to know about interpolation mode (for clipping for instance) it will get that information from the vs anyway. softpipe actually used to depend on that interpolation parameter, as it abused that structure quite a bit but no longer.

* softpipe: don't abuse the draw vertex_info struct for something differentRoland Scheidegger2016-01-071-10/+17
| | | | | | | | | | softpipe would calculate two "vertex layouts". The second one was however just used for internal purposes, draw would know nothing about it even though it looked exactly the same as the other one we tell draw about. So, store that information separately as this was just confusing. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Edward O'Callaghan <[email protected]>

* draw: implement pipeline statistics in the draw moduleZack Rusin2013-04-161-0/+4
| | | | | | | | | | | | | This is a basic implementation of the pipeline statistics in the draw module. The interface is similar to the stream output statistics and also requires that the callers explicitly enable it. Included is the implementation of the interface in llvmpipe and softpipe. Only softpipe enables the pipeline statistics capability though because llvmpipe is lacking gathering of the fragment shading and rasterization statistics.

* softpipe: use the polygon stipple utility moduleBrian Paul2011-07-211-1/+1
| | | | | | | | | | This is an alternative to the draw module's polygon stipple stage. The softpipe implementation here is just a test. The advantange of using the new polygon stipple utility module (with other drivers) is we can avoid software vertex processing in the draw module and get much better performance. Polygon stipple doesn't require special vertex processing like the other draw module stage.

* gallium: convert rasterizer state to use gl-style front/back conceptsKeith Whitwell2010-05-141-37/+4
| | | | | | | | | | | | Use front/back instead of cw/ccw throughout. Also, use offset_point/line/fill instead of offset_cw/ccw. Brings gallium representation of this state into line with its main user, and also what turns out to be the most common hardware representation. This fixes a long-standing bias in the interface towards the architecture of the software rasterizer.
* gallium: rework provoking vertex codeBrian Paul2010-05-051-1/+4
| | | | | | | | | | | | | | Builds on commit ddb0e18f6c5582d4d2cc59ffd16ad9c4639ed059 and fixes regressions in glean clipFlat test. We assume that Gallium drivers observe flatshade_first for all triangles and that all the assorted per-triangle calls in the 'draw' module also follow flatshade_first. Everything else builds on those rules. Gallium does not use follow flatshade_first for GL quads, quad strips and polygons; the "last" vertex is always the provoking vertex for those prims. So now there are separate QUAD_FIRST_PV and QUAD_LAST_PV macros in the draw primitive decomposition code instead of one QUAD macro.
