* glsl: Properly handle blocks that define the same field name.Iago Toral Quiroga2014-04-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Currently we can have name space collisions between blocks that define the same fields. For example: in block { vec4 Color; } In[]; out block { vec4 Color; } Out; These two blocks will assign the same interface name (block.Color) to the Color field in flatten_named_interface_blocks_declarations.cpp, leading to havoc. This was breaking badly the gl-320-primitive-shading test from ogl-samples. The patch uses the block instance name to avoid collisions, producing names like block.In.Color and block.Out.Color to avoid the name clash.

* i965: Fix buffer overruns in MSAA MCS buffer clearing.Eric Anholt2014-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This manifested as rendering failures or sometimes GPU hangs in compositors when they accidentally got MSAA visuals due to a bug in the X Server. Today we decided that the problem in compositors was equivalent to a corruption bug we'd noticed recently in resizing MSAA-visual glxgears, and debugging got a lot easier. When we allocate our MCS MT, libdrm takes the size we request, aligns it to Y tile size (blowing it up from 300x300=900000 bytes to 384*320=122880 bytes, 30 pages), then puts it into a power-of-two-sized BO (131072 bytes, 32 pages). Because it's Y tiled, we attach a 384-byte-stride fence to it. When we memset by the BO size in Mesa, between bytes 122880 and 131072 the data gets stored to the first 20 or so scanlines of each of the 3 tiled pages in that row, even though only 2 of those pages were allocated by libdrm. In the glxgears case, the missing 3rd page happened to consistently be the static VBO that got mapped right after the first MCS allocation, so corruption only appeared once window resize made us throw out the old MCS and then allocate the same BO to back the new MCS. Instead, just memset the amount of data we actually asked libdrm to allocate for, which will be smaller (more efficient) and not overrun. Thanks go to Kenneth for doing most of the hard debugging to eliminate a lot of the search space for the bug.

* meta: Refactor the BlitFramebuffer color CopyTexImage fallback.Eric Anholt2014-04-151-52/+41
| | | | | | | | | | | | | | | | | | | There shouldn't be anything special about copying out a subset of the src rb to a temp before texturing from it, so just do it when we're figuring out our src texture binding. This drops Anuj's change to copy an extra border of 1 pixel around the src area. I can't see how that change could be valid, and presumably if there's some filtering problem at edges we just need to set the right wrap mode. v2: Don't fall back to swrast on non-2D/RECT/2D_MS textures when we can still CopyTexSubImage.

* meta: Drop blit src size fallback.Eric Anholt2014-04-151-10/+0
| | | | | | | | | | | | | I think we can assert that renderbuffer size is <= maximum 2D texture size. Our source coordinates should have already been clipped to the src renderbuffer size, but haven't actually (so we could potentially have trouble if there's scaling, and we're in the CopyTexImage path that tries to use src size). However, this texture size dependency was blocking the next refactors, so I'm not sure if we want to go ahead with this series before we get the clipping sorted out or not.

* i965: Disable Z16 in all APIs.Kenneth Graunke2014-04-151-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We originally thought that GL 3.0 required GL_DEPTH_COMPONENT16 to map exactly to Z16. However, we misread the specification, thanks in part to LaTeX reordering the tables in the PDF. Page 180 of the GL 3.0 specification (glspec30.20080923.pdf) says: "[...] memory allocation per texture component is assigned by the GL to match the allocations listed in tables 3.16-3.18 as closely as possible. [...] Required Texture Formats [...] In addition, implementations are required to support the following sized internal formats. Requesting one of these internal formats for any texture type will allocate exactly the internal component sizes and types shown for that format in tables 3.16-3.17:" Notably, however, GL_DEPTH_COMPONENT16 does /not/ appear in table 3.16 or table 3.17. It appears in table 3.18, where the "exact" rule doesn't apply, and it falls back to the "closely as possible" rule. The confusing part is that the ordering of the tables in the PDF is: Table 3.16 (pages 182-184) Table 3.18 (bottom of page 184 to top of 185) Table 3.17 (page 185) Presumably, people saw table 3.16, then saw the table immediately following with DEPTH_COMPONENT* formats, and assumed it was 3.17. Based on a patch by Chia-I Wu, but without the driconf option to force Z16 to be used. It's not required, and there's apparently no benefit to actually using it.

| | | | | | | | | | | | | | | We've learned a few things since we originally disabled Z16; this attempts to summarize the issue. I am no expert on this subject, though, so the comment may not be totally accurate.

So, we can drop the "on Ivybridge" aspect of the comment - it's always slower.

| | | | | | | | | | | | | | | | glClearBuffer() is currently clearing all active draw color buffers (all buffers that have not been set to GL_NONE when calling glDrawBuffers) instead of only clearing the one it receives as parameter. Altough brw_clear() receives a bit mask indicating the color buffers that should be cleared, this mask is ignored when calling brw_blorp_clear_color(). This was breaking the 'fbo-drawbuffers-none glClearBuffer' piglit test. The patch provides the bit mask to brw_blorp_clear_color() so it can limit clearing to the color buffers present in the mask.

* glsl: Ignore loop-too-large heuristic if there's bad variable indexing.Kenneth Graunke2014-04-111-3/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many shaders use a pattern such as: for (int i = 0; i < NUM_LIGHTS; i++) { ...access a uniform array, or shader input/output array... } where NUM_LIGHTS is a small constant (such as 2, 4, or 8). The expectation is that the compiler will unroll those loops, turning the array access into constant indexing, which is more efficient, and which may enable array splitting and other optimizations. In many cases, our heuristic fails - either there's another tiny nested loop inside, or the estimated number of instructions is just barely beyond the threshold. So, we fail to unroll the loop, leaving the variable indexing in place. Drivers which don't support the particular flavor of variable indexing will call lower_variable_index_to_cond_assign(), which generates piles and piles of immensely inefficient code. We'd like to avoid generating that. This patch detects unsupported forms of variable-indexing in loops, where the array index is a loop induction variable. In that case, it bypasses the loop-too-large heuristic and forces unrolling. Improves performance in various microbenchmarks: Gl32PSBump8 by 47%, Gl32ShMapVsm by 80%, and Gl32ShMapPcf by 27%. No changes in shader-db. v2: Check ir->array for being an array or matrix, rather than the ir_dereference_array itself. v3: Fix and expand statistics in commit message.
