* draw: fix a regression in computing max eltZack Rusin2013-06-171-0/+1
| | | | | | | | | | | | | gl can use elts without setting indices, in which case our eltMax was set to 0 and always invoking the overflow condition. So by default set eltMax to maximum, it will be curbed by draw_set_indexes (if it ever comes) and if not then it will let gl's glVertexPointer/glDrawArrays work correctly. Fixes piglit's triangle-rasterization-overdraw test. Signed-off-by: Zack Rusin <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

| | | | | Commit 6fe0453c339b6e894e0ee8d2200e7638a43ed21e broke half-float vertex arrays. This reverts a part of that commit, and explains why.

| | | | | | | | | When a resource is busy and is mapped with PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE, the underlying bo is replaced. We need to mark states affected by the resource dirty. With this change, we no longer have to emit vertex buffers and index buffer unconditionally.

* ilo: re-emit states that involve resourcesChia-I Wu2013-06-134-21/+23
| | | | | | | Even with hardware contexts, since we do not pin resources, we have to re-emit the states so that the resources are referenced (by cp->bo) and their offsets are updated in case they are moved. This also allows us to elimiate cp flush in is_bo_busy().

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner. The patch does not regress piglit on llvmpipe and on i965 on sandy bridge.

* draw: enable user plane clipping when clipdistance is usedZack Rusin2013-06-102-7/+20
| | | | | | | | | | | | | | | | | Draw depended on clip_plane_enable being set in the rasterizer to use clipdistance registers for clipping. That's really unfriendly because it requires that rasterizer state to have variants for every shader out there. Instead of depending on the rasterizer lets extract the info from the available state: if a shader writes clipdistance then we need to use it and we need to clip using a number of planes equal to the number of writen clipdistance components.

* draw: Fix type mismatch between draw_private.h and LLVMRichard Sandiford2013-06-101-1/+1
| | | | | | | | | | | | | | | draw_vertex_buffer declared the size field to be a size_t, but the LLVM code used an int32 instead. This caused problems on big-endian 64-bit targets, because the first 32-bit chunk of the 64-bit size_t was always 0. In one sense size_t seems like a good choice for a size, so one fix would have been to try to get the LLVM code to use the equivalent of size_t too. However, in practice, the size is taken from things like ~0 or width0, both of which are int-sized, so it seemed simpler to make the size field int-sized as well.
