From: Jason Ekstrand Date: Mon, 2 Dec 2019 20:51:30 +0000 (-0600) Subject: anv: Set up VMA heaps independently from memory heaps X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b47bc0202a846d039ddd613add6ecfde30e6ab7e;p=mesa.git anv: Set up VMA heaps independently from memory heaps Our VMA allocations are really independent from the memory heaps we expose via the API. The only thing that really matters is the GTT size so we can make the high heap the right size.
