2008-04-24draw: handle edgeflags and reset-line-stipple againKeith Whitwell
2008-04-23gallium: fix issues in recursive flushingBrian Paul
When flushing/rendering, some stages (like AA line/point) need to set pipe/driver state. Those driver functions often call draw_flush(). That leads to recursion. Use new draw->suspend_flush flag to explicitly prevent that in the key places. Remove the draw->vcache_flushing field. Reuse draw->flushing as a debug/assertion var.
2008-04-22gallium: added a flushing_vcache flag, test in draw_do_flush()Brian Paul
Fixes broken polygon stipple, aaline, aapoint stages
2008-04-22draw: disable broken edgeflag code - didn't work & was killing performanceKeith Whitwell
2008-04-21draw: propogate lots of errorsKeith Whitwell
2008-04-19draw: move incoming vertex state into draw->ptKeith Whitwell
This state is effectively private to the vertex processing part of the draw module.
2008-04-16draw: make pt run pipeline when need_pipeline is true, not just when clippedKeith Whitwell
2008-04-06draw: fix edgeflag handling on the pt pathsKeith Whitwell
Encode edgeflags (and reset_stipple info) into the top two bits of the fetch elements. This info could be moved elsewhere, but for now we can live with a 1<<30 maximum element size... Also use the primitive decomposition code from draw_prim.c verbatim, as it includes all this stuff and is known to work.
2008-04-02draw: Set the backend prim in the pt 'prepare' operationKeith Whitwell
Leaving it until 'run' is bad as the primitive is pretty much state for some drivers and so needs to get set early. In some drivers this is used to determine things like vertex format, etc -- by the time we get to 'run', it's too late to change this.
2008-04-01draw: more flatshade_first changesKeith Whitwell
- Reduce the number of changes to the normal vertex ordering - Assume that the hardware knows how to do this in the standard case. - Add support to the passthrough vcache path.

2008-03-23draw: fix some unsigned vs ushort confusionKeith Whitwell
Middle-end elements are ushort, but prior to that have to treat all elements as unsigned to avoid wrapping and/or overruns.
2008-03-23gallium: beginnings of draw module vertex reworkKeith Whitwell
Trying to put a structure in place that we can actually optimize. Initially just implementing a passthrough mode, this will fairly soon replace all the vertex_cache/prim_queue/shader_queue stuff that's so hard to understand... Split the vertex processing into a couple of distinct stages: - Frontend - Prepares two lists of elements (fetch and draw) to be processed by the next stage. This stage doesn't fetch or draw vertices, but makes the decision which to draw. Multiple implementations of this will implement different strategies, currently just a vcache implementation. - MiddleEnd - Takes the list of fetch elements, fetches them, runs the vertex shader, cliptest, viewport transform on them to produce a linear array of vertex_header vertices. - Passes that list of vertices, plus the draw_elements (which index into that list) onto the backend - Backend - Either the existing primitive/clipping pipeline, or the vbuf_render hardware backend provided by the driver. Currently, the middle-end is the old passthrough code, and it build hardware vertices, not vertex_header vertices as above. It may be that passthrough is a special case in this respect.
