This fixes a number of tests from dEQP-GLES31.functional.texture.border_clamp.* Signed-off-by: Gert Wollny Reviewed-by: Roland Scheidegger --- diff --git a/src/gallium/drivers/softpipe/sp_tex_sample.c b/src/gallium/drivers/softpipe/sp_tex_sample.c index a3a047b9502..88636459454 100644 --- a/src/gallium/drivers/softpipe/sp_tex_sample.c +++ b/src/gallium/drivers/softpipe/sp_tex_sample.c @@ -318,7 +318,7 @@ static void wrap_linear_clamp_to_border(float s, unsigned size, int offset, int *icoord0, int *icoord1, float *w) { - const float min = -0.5F; + const float min = -1.0F; const float max = (float)size + 0.5F; const float u = CLAMP(s * size + offset, min, max) - 0.5f; *icoord0 = util_ifloor(u);
