2056 * "In almost all circumstances, if an object’s vertices are actually
2057 * modified by this clamping (i.e., had X or Y coordinates outside of
2058 * the guardband extent the rendered object will not match the intended
2059 * result. Therefore software should take steps to ensure that this does
2060 * not happen - e.g., by clipping objects such that they do not exceed
2061 * these limits after the Drawing Rectangle is applied."
2063 * I believe the fundamental restriction is that the rasterizer (in
2064 * the SF/WM stages) have a limit on the number of pixels that can be
2065 * rasterized. We need to ensure any coordinates beyond the rasterizer
2066 * limit are handled by the clipper. So effectively that limit becomes
2067 * the clipper's guardband size.
2069 * It goes on to say:
2071 * "In addition, in order to be correctly rendered, objects must have a
2072 * screenspace bounding box not exceeding 8K in the X or Y direction.
2073 * This additional restriction must also be comprehended by software,
2074 * i.e., enforced by use of clipping."
2076 * This makes no sense. Gen7+ hardware supports 16K render targets,
2077 * and you definitely need to be able to draw polygons that fill the
2078 * surface. Our assumption is that the rasterizer was limited to 8K
2079 * on Sandybridge, which only supports 8K surfaces, and it was actually
2080 * increased to 16K on Ivybridge and later.
2082 * So, limit the guardband to 16K on Gen7+ and 8K on Sandybridge.

3972 * and the "UAV coherency required" bit set on the 3DPRIMITIVE command
3973 * are redundant within the current image, atomic counter and SSBO GL
3974 * APIs, which all have very loose ordering and coherency requirements
3975 * and generally rely on the application to insert explicit barriers when
3976 * a shader invocation is expected to see the memory writes performed by
3977 * the invocations of some previous primitive. Regardless of the value
3978 * of "UAV coherency required", the "Accesses UAV" bits will implicitly
3979 * cause an in most cases useless DC flush when the lowermost stage with
3980 * the bit set finishes execution.
3982 * It would be nice to disable it, but in some cases we can't because on
3983 * Gen8+ it also has an influence on rasterization via the PS UAV-only
3984 * signal (which could be set independently from the coherency mechanism
3985 * in the 3DSTATE_WM command on Gen7), and because in some cases it will
3986 * determine whether the hardware skips execution of the fragment shader
3987 * or not via the ThreadDispatchEnable signal. However if we know that
3988 * GEN8_PS_BLEND_HAS_WRITEABLE_RT is going to be set and
3989 * GEN8_PSX_PIXEL_SHADER_NO_RT_WRITE is not set it shouldn't make any
3990 * difference so we may just disable it here.
3992 * Gen8 hardware tries to compute ThreadDispatchEnable for us but doesn't
3993 * take into account KillPixels when no depth or stencil writes are
3994 * enabled. In order for occlusion queries to work correctly with no
3995 * attachments, we need to force-enable here.
