Brian Paul 7319ae0954 llvmpipe: remove tile clipping code 
The surface is always a multiple of the tile size now.

Brian Paul ec459f2aec llvmpipe: asst. task-related clean-ups 2010-01-19 16:58:25 -07:00
Brian Paul 0fccfc9cc0 llvmpipe: remove unneeded DEBUG checks, use step var 2010-01-19 09:30:44 -07:00
Brian Paul 62623c4dc5 llvmpipe: added show_tiles and show_subtiles debug options 
These options draw lines over the tiles to show the 64x64 tile
bounds and 16x16 sub-tile bounds.  For debugging/visualization.

Keith Whitwell 591401ff05 llvmpipe: use new u_ringbuffer for scene queue 2010-01-17 00:30:23 +00:00
Brian Paul 2797f2bf57 llvmpipe: generate two shader varients, one omits triangle in/out testing 
When we know that a 4x4 pixel block is entirely inside of a triangle
use the jit function which omits the in/out test code.

Results in a few percent speedup in many tests.

Brian Paul 2ba1c8189a llvmpipe: use one loop in lp_rast_clear_zstencil() 
This is just a tiny bit faster.
 2010-01-13 18:58:42 -07:00
Brian Paul f94a99170e llvmpipe: optimize lp_rast_clear_color() for non-gray colors 
This makes a big difference in progs that clear to a non-gray color.
Some demos are 30-50% faster.

Keith Whitwell 4231006e29 llvmpipe: add bin debugger 
Adjust definition of empty_bin according to what's actually in empty
bins.  We often have a state packet before/after load commands.

Still need to do something about the fence packets.

Keith Whitwell 95ee14f147 llvmpipe: implement lp_rast_load_zstencil 
Load zbuffer contents for binned scenes that don't start with a clear
and which have a bound zbuffer.

Keith Whitwell db83ad4b43 llvmpipe: improve empty-bin test further 
Remove unused param, add comments.  Thanks to Brian for review.
 2010-01-13 16:29:39 +00:00
Keith Whitwell f4b29e6ad3 llvmpipe: improve empty-bin test 
We emit at most two clear packets (color and z respectively).

Keith Whitwell c1a0441602 llvmpipe: initial mrt support 
Non-mrt apps work, and the code looks correct, but not many mrt test apps
handy atm...

Brian Paul 808170a0ff llvmpipe: replace INT_MIN/2 with INT_MIN 
Since changing the in/out test we can just use INT_MIN to be sure the
comparison against the step values always passes.

Brian Paul b9d33db0a4 llvmpipe: improve the in/out test a little 
Instead of:
  s = c + step
  m = s > 0
Do:
  m = step > c  (with negated c)

Brian Paul ab94381930 llvmpipe: do final the pixel in/out triangle test in the fragment shader 
The test to determine which of the pixels in a 2x2 quad is now done in
the fragment shader rather than in the calling C code.  This is a little
faster but there's a few more things to do.

Note that the step[] array elements are in a different order now.  Rather
than being in row-major order for the 4x4 grid, they're in "quad-major"
order.  The setup of the step arrays is a little more complicated now.
So is the course/intermediate tile test code, but some lookup tables
help with that.

Next steps:
 - early-cull 2x2 quads which are totally outside the triangle.
 - skip the in/out test for fully contained quads
 - make the in/out comparison code tighter/faster.

Keith Whitwell 663750d556 llvmpipe: rename bins to scene 
It was pretty confusing having an entity named "bin" and another named
"bins", not least because sometimes there was a need to talk about >1
of the "bins" objects, which couldn't be pluralized any further...

Scene is a term used in a bunch of places to talk about what a binner
operates on, so it's a decent choice here.

Brian Paul aab1ceceec llvmpipe: implement threaded rasterization 
The LP_NUM_THREADS env var controls how many threads are created.
The default (and max) is 4, for now.
If LP_NUM_THREADS = 0, threading is not used.

Brian Paul 3a06c113c7 llvmpipe: repartition lp_rasterizer state for threading 
Some of the state is per-thread.  Put that state in new lp_rasterizer_task
struct.

Brian Paul 8a23105fa0 llvmpipe: still more bin code reorganization 
Move tiles_x,y fields from setup state into bin state.
Move more bin-adding commands into lp_bin.[ch].
 2009-12-04 15:59:25 -07:00
Brian Paul 01b1900084 llvmpipe: reorganization of binning data structions and funtions 
New lp_bins struct contains all bin information.
More move bin-related code into lp_bin.[ch]
Use new/updated bin-access functions to hide implementation details.
The result is more/cleaner separation between the setup and rast components.
This will make double-buffering of the bins easier, etc.

Brian Paul b533b56750 llvmpipe: move lp_rasterize_bin() into lp_rast.c

Brian Paul a08d630216 llvmpipe: use LP_DBG() macro everywhere 2009-12-04 14:11:25 -07:00
Brian Paul b1659b9213 llvmpipe: bin state-change commands 
Previously, each triangle had a pointer to the state to use for shading.
Now we insert state-change commands into the bins.  When we execute one
of those commands we just update a 'current state' pointer and use that
pointer when calling the jit shader.

When inserting state-change commands into a bin we check if the previous
command was also a state-change command and simply replace it.  This
avoids accumulating useless/redundant state-change commands.

Brian Paul 866e6856d3 llvmpipe: execute shaders on 4x4 blocks instead of 8x2 
This matches the convention used by the recursive rasterizer.
Also fixed assorted typos, comments, etc.
Now tri-z.c, gears.c, etc look basically right but there's still some
cracks in triangle rasterization.
