* llvmpipe: drop scissor planes early if the tri is fully inside themRoland Scheidegger2016-02-021-30/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | If the tri is fully inside a scissor edge (or rather, we just use the bounding box of the tri for the comparison), then we can drop these additional scissor "planes" early. We do not even need to allocate space for them in the tri. The math actually appears to be slightly iffy due to bounding boxes being rounded, but it doesn't matter in the end. Those scissor rects are costly - the 4 planes from the scissor are already more expensive to calculate than the 3 planes from the tri itself, and it also prevents us from using the specialized raster code for small tris. This helps openarena performance by about 8% or so. Of course, it helps there that while openarena often enables scissoring (and even moves the scissor rect around) I have not seen a single tri actually hit the scissor rect, ever. v2: drop individual scissor edges, and do it earlier, not even allocating space for them. v3: help the compiler a bit with simpler code, suggested by Brian.

* llvmpipe: scale up bounding box planes to subpixel precisionRoland Scheidegger2016-01-131-10/+10
| | | | | | | | | Otherwise some planes we get in rasterization have subpixel precision, others not. Doesn't matter so far, but will soon. (OpenGL actually supports viewports with subpixel accuracy, so could even do bounding box calcs with that). Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: do 64bit plane calculations in the sse pathRoland Scheidegger2016-01-081-5/+11
| | | | | | | | | | | | The sse path was pretty much disabled for practical purposes because the largest allowed fb size was 128x128. So, adapt it for 64bit plane calculations. This is actually not that difficult, though a problem is that we can't do a signed 32x32->64bit mul, only unsigned, so need to fix that up. Overall, the code still looks reasonable, though it's not like changes there in setup really make much of a difference in the end...

* llvmpipe: use provoking vertex for layer/viewportRoland Scheidegger2015-12-041-9/+16
| | | | | | | | | | | | | | | | | | | | d3d10 actually requires using provoking (first) vertex. GL is happy with any vertex (as long as we say it's undefined in the corresponding queries). Up to now we actually used vertex 0 for viewport index, and vertex 1 for layer (for tris), which really didn't make sense (probably a typo). Also,$ since we reorder vertices of clockwise triangle, that actually meant we used a different vertex depending if the traingle was cw or ccw (still ok by gl). However, it should be consistent with what draw (clip) does, and using provoking vertex seems like the sensible choice (draw clip will be fixed next as it is totally broken there). While here, also use the correct viewport always even when not needed in setup (we pass it down to jit fragment shader it might be needed there for getting correct near/far depth values). No piglit changes. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

* llvmpipe: clamp fragment shader depth write to the current viewport depth range.Matthew McClure2013-12-091-5/+6
| | | | | | | | | | | | | | | | | With this patch, generate_fs_loop will clamp any fragment shader depth writes to the viewport's min and max depth values. Viewport selection is determined by the geometry shader output for the viewport array index. If no index is specified, then the default viewport index is zero. Semantics for this path can be found in draw_clamp_viewport_idx and lp_clamp_viewport_idx. lp_jit_viewport was created to store viewport information visible to JIT code, and is validated when the LP_NEW_VIEWPORT dirty flag is set. lp_rast_shader_inputs is responsible for passing the viewport_index through the rasterizer stage to fragment stage (via lp_jit_thread_data).

* llvmpipe: add support for nested / overlapping queriesRoland Scheidegger2013-06-261-2/+2
| | | | | | | | | | | | | | | | OpenGL doesn't support this but d3d10 does. It is a bit of a pain as it is necessary to keep track of queries still active at the end of a scene, which is also why I cheat a bit and limit the amount of simultaneously active queries to (arbitrary) 16 (simplifies things because don't have to deal with a real list that way). I can't think of a reason why you'd really want large numbers of overlapping/nested queries so it is hopefully fine. (This only affects queries which need to be binned.) v2: don't copy remainder of array when deleting an entry simply replace the deleted entry with the last one (order doesn't matter).

Luckily don't need to touch the jitted code. (Clears invoked via pipe's clear_render_target method will not work however since the pipe_util_clear function used for it doesn't handle clearing multiple layers yet.) v2: per Brian's suggestion, prettify var initialization and add some comments, add assertion for impossible layer specification for surface.

* llvmpipe: avoid generating tri_16 for tris which extend past tile boundsKeith Whitwell2010-11-021-5/+10
| | | | | | | | | | Don't trim triangle bounding box to scissor/draw-region until after the logic for emitting tri_16. Don't generate tri_16 commands for triangles with untrimmed bounding boxes outside the current tile. This is important as the tri-16 itself can extend past tile bounds and we don't want to add code to it to check against tile bounds (slow) or restrict it to locations within a tile (pessimistic).
