Subject: intel/eu: Use descriptor constructors for pixel interpolator messages.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b10b4e7c459aecdb788de5195cca809c680663e1;p=mesa.git

intel/eu: Use descriptor constructors for pixel interpolator messages.

v2: Use SET_BITS macro instead of left shift (Ken).
