When clients queries tile Info from tile index and expects accurate
tileSplit info, bits per pixel info is required to be provided since
this is necessary for computing tileSplitBytes; otherwise Addrlib will
return value of "tileBytes" instead if bpp is 0 - which is also
current logic. If clients don't need tileSplit info, it's OK to pass
bpp with value 0.
Kaveri (2-pipe) macro tiling mode table was initially set to all
4-aspect-ratio so the swizzling path did not work for it and then we
chose to pad the offset. We now discover the root cause is that if
ratio > 2, the swizzling path does not work. So we can safely use the
same path for Kaveri.
Even if surface info input flag "tcComaptible" is enabled, tc
compatible may be not supported if tile split happens for depth
surfaces. Add a new flag in output structure to notify client to
disable tc compatible in this case.
Change the logic to compute tc compatible stencil info via depth's
tileIndex instead of using depth's tileInfo. So the clients can get
the stencil's tileInfo computed from macroModeTable. If the stencil
tileInfo is same as depth tileInfo, then stencil is tc compatible;
otherwise, stencil is not tc compatible. The current suggestion is to
create another stencil buffer with the tc compatible tileInfo, use
depth-to-color copy to decompress and tile convert the rendered
stencil to tc compoatible stencil (And use the new stencil buffer to
program TC).
