Hm, nouveau nv50 (and probably nvc0) does: if (ib->buffer) { nv50->idxbuf.offset = ib->offset; BCTX_REFN(nv50->bufctx_3d, INDEX, nv04_resource(ib->buffer), RD); } else { nv50->idxbuf.user_buffer = ib->user_buffer; } Is the offset really supposed to be applied to the user buffer? I figured the point of the offset was that you couldn't provide an offset into a pipe_resource otherwise, while with a user ptr, you can just add it in yourself... > --- > src/gallium/auxiliary/indices/u_primconvert.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/src/gallium/auxiliary/indices/u_primconvert.c > b/src/gallium/auxiliary/indices/u_primconvert.c > index 4632781..eba1f9e 100644 > --- a/src/gallium/auxiliary/indices/u_primconvert.c > +++ b/src/gallium/auxiliary/indices/u_primconvert.c > @@ -137,8 +137,9 @@ util_primconvert_draw_vbo(struct primconvert_context *pc, > src = ib->user_buffer; > if (!src) { > src = pipe_buffer_map(pc->pipe, ib->buffer, > - PIPE_TRANSFER_READ, &src_transfer) + > ib->offset; > + PIPE_TRANSFER_READ, &src_transfer); > } > + src = (const uint8_t *)src + ib->offset; > } > else { > u_index_generator(pc->primtypes_mask, > -- > 2.1.0 > _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
