If early-z is disabled, FPK is also disabled?

markhuang2007

In Mali GPU, FPK will also be disabled, if early-z is disabled?

    Hi Mark, 

    Hidden surface removal requires guarantees that the occluder is opaque before fragment shading occurs. Opacity meaning both not using the destination color (not using blending, framebuffer fetch), and with a known sample coverage (either ZS test disabled, so always passes, or a resolved ZS test, so no discards, no alpha-to-coverage). 

    HTH,
