1146 * "The vertex X and Y screen-space coordinates are also /clamped/ to the
1147 * fixed-point "guardband" range supported by the rasterization hardware"
1151 * "In almost all circumstances, if an object’s vertices are actually
1152 * modified by this clamping (i.e., had X or Y coordinates outside of
1153 * the guardband extent the rendered object will not match the intended
1154 * result. Therefore software should take steps to ensure that this does
1155 * not happen - e.g., by clipping objects such that they do not exceed
1156 * these limits after the Drawing Rectangle is applied."
1158 * I believe the fundamental restriction is that the rasterizer (in
1159 * the SF/WM stages) have a limit on the number of pixels that can be
1160 * rasterized. We need to ensure any coordinates beyond the rasterizer
1161 * limit are handled by the clipper. So effectively that limit becomes
1162 * the clipper's guardband size.
1164 * It goes on to say:
1166 * "In addition, in order to be correctly rendered, objects must have a
1167 * screenspace bounding box not exceeding 8K in the X or Y direction.
1168 * This additional restriction must also be comprehended by software,
1169 * i.e., enforced by use of clipping."
1171 * This makes no sense. Gen7+ hardware supports 16K render targets,
1172 * and you definitely need to be able to draw polygons that fill the
1173 * surface. Our assumption is that the rasterizer was limited to 8K
1174 * on Sandybridge, which only supports 8K surfaces, and it was actually
1175 * increased to 16K on Ivybridge and later.
1177 * So, limit the guardband to 16K on Gen7+ and 8K on Sandybridge.
