Hurray!

What an additional gift beside your impending new arrival, Dave ;-)

This is finally fixed by this:

commit 2239f3eaff5c72c4cb1d4a5be97feb4af3d08d25

    r600/shader: emit tessellation factors to GDS at end of TCS.

    When we are finished the shader, we read back all the tess factors
    from LDS and write them to special global memory storage using
    GDS instructions.

    This also handles adding NOP when GDS or ENDLOOP end the TCS.

Tomorrow,
I'll test this on RV730 (AGP), too and CLOSE both when all goes smooth.

(For the rendering issues with R600_DEBUG=nosb I'll open a new ticket.)

Merry Christmas!
And all the best for your family.
