From: Boris Brezillon Date: Sat, 14 Sep 2019 17:18:51 +0000 (+0200) Subject: panfrost: Allocate tiler and scratchpad BOs per-batch X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1e483a87bcaa96ca34edf82c424143f06576ce60;p=mesa.git panfrost: Allocate tiler and scratchpad BOs per-batch If we want to execute several batches in parallel they need to have their own tiler and scratchpad BOs. Let move those objects to panfrost_batch and allocate them on a per-batch basis.
