From 67426ccd428706b558ae1d8697831ce337f97412 Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Wed, 6 Feb 2019 16:26:18 -0800 Subject: [PATCH] virgl: use virgl_transfer_inline_write even less We've noticed the Team Fortress 2 engine seems to do many small calls to glSubData(..). Let's pick our heuristic based on the resource base width, not the size of a particular upload. This will cause transfers to be batched together in the transfer queue.
