* mesa: do not skip att and spot calculation for infinite lightYuanhan Liu2011-11-161-63/+50
| | | | | | | | | | | | | | | | | | glspec doesn't say that we should skip the attenuation and spot calculation for infinite light(Ppli.w == 0). Instead, it gives a same formula to do the light calculation for both finite light and infinite light(see page 62 of glspec 2.1.pdf) Also from the formula (2.4) at page 62 of glspec 2.1.pdf, we can skip attenuation calculation if Ppli.w == 0. This would fix all the intel oglc l_sed fail subcases and introduces no intel oglc regressions. v2: fix an wrong intendation(comments from Brian).

* intel: Fix separate stencil in builtin DRI2 backendChad Versace2011-11-151-9/+80
| | | | | | | | | | | | | | | | intelAllocateBuffer() was oblivious to separate stencil buffers. This patch fixes it to allocate a non-tiled stencil buffer with special pitch, just as the DDX does. Without this, any app that attempted to create an EGL surface with stencil bits would crash. Of course, this affected only environments that used the builtin DRI2 backend, such as Android and Wayland. Fixes GLBenchmark2.1 on Android on gen7. Note: This is a candidate for the 7.11 branch.

* intel: Fix region dimensions for stencil buffers received from DDXChad Versace2011-11-151-15/+16
| | | | | | | | | | | | | | | I changed the dimensions of the stencil buffer's region, as allocated by the DDX, at xf86-video-intel commit commit 3e55f3e88b40471706d5cd45c4df4010f8675c75 dri: Do not tile stencil buffer But I forgot to make the analogous update to the Intel DRI2 glue in Mesa. This patch makes that update. Surprisingly, the mismatch did not cause any bugs. But the mismatch, if left unfixed, *would* create bugs in the next commit.

* intel: Simplify stencil detiling arithmeticChad Versace2011-11-152-6/+3
| | | | | | | | | | | | | | | | When calculating the y offset needed for detiling window system stencil buffers, replace the term region->height * 2 + region->height % 2 - 1 with rb->Height - 1 . The two terms are incidentally equivalent due to some out-of-date, incorrect code in the Intel DRI2 glue for DDX. (See intel_process_dri2_buffer_with_separate_stencil(), line ``buffer_height /= 2;``). Note: This is a candidate for the 7.11 branch (only the intel_span.c hunk).

* intel: Fix intel_map_renderbuffer() for depthstencil buffers with separate ↵Chad Versace2011-11-151-1/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | stencil For a depthstencil buffer with separate stencil, intel_renderbuffer::region is null. (The regions are kept in hidden depth and stencil buffers). Since the region is null, intel_map_renderbuffer() assumed there was no data and returned a null map pointer, which in turn was dereferenced (!) by MapRenderbuffer's caller. This patch fixes intel_map_renderbuffer() to map the hidden depth buffer through the GTT and return that as the mapped pointer. Also, the stencil bits are scattered and gathered when needed.

* glsl: Always search for an exact function signature match.Kenneth Graunke2011-11-141-29/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we would fail to compile the following shader due to a bug in lazy built-in importing: #version 130 void main() { float f = abs(5.0); int i = abs(5); } The first call, abs(5.0), would fail to find a local signature, look through the built-ins, and import "float abs(float)". The second call, abs(5), would find the newly imported float signature in the local shader, and settle for that. Unfortunately, it failed to search the built-ins for the correct/exact signature, "int abs(int)". Thus, abs(5) ended up being a float, causing a bizarre type error when we tried to assign it to an int. Fixes piglit test builtin-overload-matching.frag. This is /not/ a candidate for stable branches, as it should only be possible to trigger this bug using GLSL 1.30's built-in functions that take integer arguments. Plus, the changes are fairly invasive. Signed-off-by: Kenneth Graunke <[email protected]>
* glsl: Split code to generate an ir_call out from match_function_by_name.Kenneth Graunke2011-11-141-165/+173
| | | | | | | | | | | | | | | | | | | | | | match_function_by_name performs two fairly separate tasks: 1. Hunt down the appropriate ir_function_signature for the callee. 2. Generate the actual ir_call (assuming we found the callee). Both of these are complicated. The first has to handle exact/inexact matches, lazy importing of built-in prototypes, different scoping rules for 1.10, 1.20+, and ES. Not to mention printing a user-friendly error message with pretty-printed "maybe you meant this" candidate signatures. The second has to deal with void/non-void functions, pre-call implicit conversions for "in" parmeters, and post-call "out" call conversions. Trying to do both in one function is just too unwieldy. Time to split. This patch purely moves the code to generate an ir_call into a separate function and reindents it. Otherwise, the code is identical.

* glsl: Add a new matching_signature() variant that returns exact/inexact.Kenneth Graunke2011-11-142-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | When matching function signatures across multiple linked shaders, we often want to see if the current shader has _any_ match, but also know whether or not it was exact. (If not, we may want to keep looking.) This could be done via the existing mechanisms: sig = f->exact_matching_signature(params); if (sig != NULL) { exact = true; } else { sig = f->matching_signature(params); exact = false; } However, this requires walking the list of function signatures twice, which also means walking each signature's formal parameter lists twice. This could be rather expensive. Since matching_signature already internally knows whether a match was exact or not, we can just return it to get that information for free.

* r600g: fix the representation of control-flow instructionsMarek Olšák2011-11-159-426/+536
| | | | | | | | | | | | | | | | | | | | | | | | | | We need something that looks like a compiler and not like some hacker put some functions together. /rant This is a band-aid for these two problems: - The R600 and EG control-flow instructions appear in switch statements next to each other, causing conflicts when adding new instructions. - The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29 to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST is 22:29. To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23, or 26 (directly in the definitions), such that it can be just or'd when making bytecode without any shifting. All switch statements have been divided into two, one for R600 and the other for EG. Of course, there is a better way to do this, but that is left for future work. Tested on RV730 and REDWOOD with no regressions. v2: minor cleanup as per Alex's comment. Reviewed-by: Alex Deucher <[email protected]>
