Subject: ilo: add functions for Gen8 relocs
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=bfc8a726096c752f15b1e2f1043fe284f0effb18

ilo: add functions for Gen8 relocs

Extend ilo_builder_writer_reloc() for Gen8 memory addressing.  Add new
wrappers, ilo_builder_surface_reloc64(() and ilo_builder_batch_reloc64().
