Comme= nt # 29 on bug 11089= 7 from = Richard Thier 
Okay this is weird for me:

  /* src/gallium/drivers/r300/r300_texture_desc.c */
  399             /* Get the HIZ buffer size in dwords. */
  400             hiz_numdw =3D (stride * height) / (8*8 * pipes);
  401=20
  402             /* Check whether we have enough HIZ memory. */
  403             if (hiz_numdw <=3D screen->caps.hiz_ram * pipes) {
  404                 tex->tex.hiz_dwords[i] =3D hiz_numdw;
  405                 tex->tex.hiz_stride_in_pixels[i] =3D stride;
  406             } else {
  407                 tex->tex.hiz_dwords[i] =3D 0;
  408                 tex->tex.hiz_stride_in_pixels[i] =3D 0;
  409             }

  (gdb) p hiz_numdw
  $35 =3D 1128
  (gdb) p screen->caps.hiz_ram
  $36 =3D 0
  (gdb)

(!) Is it normal to have zero hiz_ram on this
card???????????????????????????????????????????????

Btw:

info.r300_num_z_pipes =3D=3D 1
info.r300_num_gb_pipes =3D=3D 3 (this is in the pipes var)
