Subject: intel: Initial IS_GEN7 plumbing.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=89a82d72cafc1efbcf099e5229ba9b1cb53504f0;p=mesa.git

intel: Initial IS_GEN7 plumbing.

Currently, IS_GEN7, IS_IVYBRIDGE, IS_IVB_GT1, and IS_IVB_GT2 all return
false.  This allows me to write the code for them before actually adding
the PCI IDs and thus enabling the hardware.
