Subject: etnaviv: use NORMALIZE_SIGN_EXTEND
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=06d7071bca1a44e4712ea9a7474eb25db6292b15;p=mesa.git

etnaviv: use NORMALIZE_SIGN_EXTEND

The blob driver does something like this for all vertex formats:

if (normalize) {
   if (OPENGL_ES30)
      val = VIVS_FE_VERTEX_ELEMENT_CONFIG_NORMALIZE_SIGN_EXTEND;
   else
      val = VIVS_FE_VERTEX_ELEMENT_CONFIG_NORMALIZE_ON;
} else {
   val = VIVS_FE_VERTEX_ELEMENT_CONFIG_NORMALIZE_OFF;
}

As there is no way to get to that information in gallium we always
assume OPENGL_ES30.
