--- Comment #4 from Talha Nassar <talha.nassar at intel.com> ---
After investigating this issue, it appears that the register is holding the
value to set WaEnableFloatBlendOptimization. The issue is that HW currently
does not have this register muxed to be read. This test reads bit4 to check if
the WA is enabled but returns 0 for the aforementioned reason.

For ICL, the register is used to enable this feature and remains so. This will
only move to a state cmd for next gen.

Can we merge back the patch that was reverted?
