Subject: intel/batch-decoder: fix vertex buffer size calculation for gen<8
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=db39a44f105213e5e648a17ba94fca965cb19654

intel/batch-decoder: fix vertex buffer size calculation for gen<8

It should be incremented by one according to
how it is calculated by 'emit_vertex_buffer_state':
  "\#if GEN_GEN < 8
      .BufferAccessType = step_rate ? INSTANCEDATA : VERTEXDATA,
      .InstanceDataStepRate = step_rate,
   \#if GEN_GEN >= 5
      .EndAddress = ro_bo(bo, end_offset - 1),
   \#endif
   \#endif"
