Hurray!

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

This is finally fixed by this:

commit 2239f3eaff5c72c4cb1d4a5be97feb4af3d08d25
Author: Dave Airlie <airlied@redhat.com>
Date:   Mon Nov 30 15:48:22 2015 +1000

    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.

    Signed-off-by: Dave Airlie <airlied@redhat.com>

:040000 040000 101f51186ea311e90fa8423ee772f2b1076737bf
b01929ff47ca5035660b2c84ca2fdeb6604549fa M  src

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.

--- Comment #10 from Dieter Nützel <Dieter@nuetzel-hh.de> ---
OK, 

is this SOLVED by 'accident'?

For RV730 GPU hang (Bug 83319) the above identified commit do NOT solve the
hang.
(Bug is updated, now.)

The observed issues with R600_DEBUG=nosb for all three 'raytrace' variants
(vsraytrace/fsraytrace/gsraytrace) stays.
latest: Mesa 11.2.0-devel (git-6470435)

I'll open a new ticket for this.
