Author: Eric Anholt <[email protected]> Date: Fri Sep 3 21:56:53 2010 -0700 i965: set the source width/stride when handling reladdr dests in the VS. This is a requirement specified in the docs. No behavior change in glsl-vs-varying-array.shader_test that violated these requirements. --- src/mesa/drivers/dri/i965/brw_vs_emit.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_vs_emit.c b/src/mesa/drivers/dri/i965/brw_vs_emit.c index 1d88c6b..49ef974 100644 --- a/src/mesa/drivers/dri/i965/brw_vs_emit.c +++ b/src/mesa/drivers/dri/i965/brw_vs_emit.c @@ -1069,6 +1069,12 @@ move_to_reladdr_dst(struct brw_vs_compile *c, struct brw_reg indirect = brw_vec4_indirect(0,0); struct brw_reg acc = retype(vec1(get_tmp(c)), BRW_REGISTER_TYPE_UW); + /* Because destination register indirect addressing can only use + * one index, we'll write each vertex's vec4 value separately. + */ + val.width = BRW_WIDTH_4; + val.vstride = BRW_VERTICAL_STRIDE_4; + brw_push_insn_state(p); brw_set_access_mode(p, BRW_ALIGN_1); _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
