Hi Gurus:
I'm curious about the register GFX_FLSH_CNT(0x101008) in
i915_gem_gtt.c. Does these register exist in recently generations? After
digging into b-spec, it looks only BXT and CHV has this register. Does
the desktop platform also have this register which needs to be written
after updating GGTT MMIOs?
BTW: Looks windows driver haven't used this MMIO... So whose behavior is
the right behavior?
Thanks,
Zhi.
