| | | | | | | | This partially reverts commit 363ff844753c46ac9c13866627e096b091ea81f8. It caused severe performance drops in Nexuiz. Reported by Phoronix. Tested by me on r300g and by IRC people on r600g.
* i965 gen6: Fix incorrect order of dwords in gen6_update_sol_indices()Paul Berry2011-12-241-1/+1
| | | | | | | | | | | | When updating SOL indices, we were accidentally putting the starting index in dword 1 and the SVBI number to increment in dword 2--these should be reversed. Usually both of these values are zero, so we didn't see any problem. However, if a transform feedback operation spans multiple batch buffers, the starting index will be nonzero. Fixes piglit test "EXT_transform_feedback/intervening-read output". Reviewed-by: Kenneth Graunke <[email protected]>
* i965 gen6: Fix transform feedback of triangle strips.Paul Berry2011-12-242-18/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When rendering triangle strips, vertices come down the pipeline in the order specified, even though this causes alternate triangles to have reversed winding order. For example, if the vertices are ABCDE, then the GS is invoked on triangles ABC, BCD, and CDE, even though this means that triangle BCD is in the reverse of the normal winding order. The hardware automatically flags the triangles with reversed winding order as _3DPRIM_TRISTRIP_REVERSE, so that face culling and two-sided coloring can be adjusted to account for the reversed order. In order to ensure that winding order is correct when streaming vertices out to a transform feedback buffer, we need to alter the ordering of BCD to BDC when the first provoking vertex convention is in use, and to CBD when the last provoking vertex convention is in use. To do this, we precompute an array of indices indicating where each vertex will be placed in the transform feedback buffer; normally this is SVBI[0] + (0, 1, 2), indicating that vertex order should be preserved. When the primitive type is _3DPRIM_TRISTRIP_REVERSE, we change this order to either SVBI[0] + (0, 2, 1) or SVBI[0] + (1, 0, 2), depending on the provoking vertex convention. Fixes piglit tests "EXT_transform_feedback/tessellation triangle_strip" on Gen6. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | Stop using deprecated renderbuffer PutRow() function. Note that we aren't using Map/UnmapRenderbuffer() yet because this call is inside a swrast_render_start/finish() pair. v2: use _mesa_pack_uint_24_8_depth_stencil_row(), per Eric.

| | | | | | | | | | | The functions that read depth/stencil values understand all (packed) depth/stencil buffer formats now so there's no reason to use the wrappers. Also, improve the format checks in fast_copy_pixels() to catch mismatched depth/stencil cases. v2: fix the test for combined depth+stencil buffers, per Eric.
