Subject: freedreno: Make the pack struct have a .qword for wide addresses.
X-Git-Tag: upstream/21.0.0~5501
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3b3772d6e694da91ead40c144292f5a93b2aa42e;p=platform%2Fupstream%2Fmesa.git

freedreno: Make the pack struct have a .qword for wide addresses.

Storing a precomputed iova in reg packing wasn't possible because you'd
truncate to 32 bits.  Making it be .qword makes it possible.
