Should fix piglit: gl-1.4-polygon-offset (formerly a glean test) (untested, ported from radeonsi) Reviewed-by: Edward O'Callaghan Reviewed-by: Alex Deucher Cc: mesa-stable@lists.freedesktop.org --- src/gallium/drivers/r600/evergreen_state.c | 2 +- src/gallium/drivers/r600/r600_state.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/r600/evergreen_state.c b/src/gallium/drivers/r600/evergreen_state.c index f7a76f6..95987ee 100644 --- a/src/gallium/drivers/r600/evergreen_state.c +++ b/src/gallium/drivers/r600/evergreen_state.c @@ -485,7 +485,7 @@ static void *evergreen_create_rs_state(struct pipe_context *ctx, /* offset */ rs->offset_units = state->offset_units; - rs->offset_scale = state->offset_scale * 12.0f; + rs->offset_scale = state->offset_scale * 16.0f; rs->offset_enable = state->offset_point || state->offset_line || state->offset_tri; if (state->point_size_per_vertex) { diff --git a/src/gallium/drivers/r600/r600_state.c b/src/gallium/drivers/r600/r600_state.c index 8488188..5cc2283 100644 --- a/src/gallium/drivers/r600/r600_state.c +++ b/src/gallium/drivers/r600/r600_state.c @@ -473,7 +473,7 @@ static void *r600_create_rs_state(struct pipe_context *ctx, /* offset */ rs->offset_units = state->offset_units; - rs->offset_scale = state->offset_scale * 12.0f; + rs->offset_scale = state->offset_scale * 16.0f; rs->offset_enable = state->offset_point || state->offset_line || state->offset_tri; if (state->point_size_per_vertex) { -- 2.7.4
