| | | | | | | | | | | | | | | | | | | Surprising this bug survived so long, we were missing a clamp (in the linear filtering version). (Valgrind complained a lot about invalid reads with piglit texwrap, I've also seen spurios failures in this test which might have happened due to this. Valgrind probably didn't complain before the alignment reduction in llvmpipe to 4x4 since the test is using tiny textures so the reads were still always well within allocated area.) While here, also do an effective clamp (after half subtraction) of [0,length-0.5] instead of [0, length-1] which saves an instruction (the filtering weight could be different due to this, but only if both texels point to the same max texel so it doesn't matter).

* llvmpipe: reduce alignment requirement for resources from 64x64 to 4x4Roland Scheidegger2013-05-317-53/+83
| | | | | | | | | | | | | | | | | | | | | | | | The overallocation was very bad especially for things like 1d array textures which got blown up by a factor of 64. (Even ordinary smallish 2d textures benefit a lot from this, a mipmapped 64x64 rgba8 texture previously used 7*16kB = 112kB instead of now ~22kB.) 4x4 is chosen because this is the size the jit functions run on, so making it smaller is going to be a bit more complicated. It is actually not strictly 4x4 pixel, since we'd want to avoid situations where different threads are rendering to the same cacheline so we keep cacheline size alignment in x direction (often 64bytes). To make this work introduce new task width/height parameters and make sure clears don't clear the whole tile if it's a partial tile. Likewise, the rasterizer may produce fragments outside the 4x4 blocks present in a tile, so don't call the jit function for them. This does not yet fix rendering to buffers (which cannot have any y alignment at all), and 1d/1d array textures are still overallocated by a factor of 4. v2: replace magic number 4 with LP_RASTER_BLOCK_SIZE, fix size of buffers allocated (needed in case we render to them).

* intel: Add multisample scaled blitting in blorp engineAnuj Phogat2013-05-304-74/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | In traditional multisampled framebuffer rendering, color samples must be explicitly resolved via BlitFramebuffer before doing the scaled blitting of the framebuffer. So, scaled blitting of a multisample framebuffer takes two separate calls to BlitFramebuffer. This patch implements the functionality of doing multisampled scaled resolve using just one BlitFramebuffer call. Important changes involved in this patch are listed below: - Use float registers to scale and offset texture coordinates. - Change offset computation to consider float coordinates. - Round the scaled coordinates down to nearest integer. - Modify src texture coordinates clipping to account for scaling.. - Linear filter is not yet implemented in blorp. So, don't use blorp engine to do single sampled scaled blitting. V3: Fix nearest filtering issue in scaled blits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Pre-Haswell hardware doesn't support an arbitrary restart index, and instead compares the index buffer value against 0xFF for byte-size buffers, 0xFFFF for short-size buffers, or 0xFFFFFFFF for unsigned integer buffers. OpenGL allows the restart index to be an arbitrary unsigned integer. When comparing against byte/short types, the index buffer value should be promoted to a full 32-bit integer before doing the comparison. The restart index is /not/ supposed to be masked to byte/short size. This means that with certain restart indexes, the comparison should always fail. For example, a restart index of 0xF000FFFF should never match any byte/short index buffer values due to the extra high bits. We must not enable hardware primitive restart in such a case. For now, fall back to software primitive restart as it's the simplest fix. In the future, we could detect restart indexes that will never match and skip both hardware and software primitive restart.
