From 36006e3cec79584cf62fe7dd13ac4b8f07c37eee Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 15 Nov 2018 11:29:54 +0100 Subject: [PATCH] radv/winsys: remove the max IBs per submit limit for the sysmem path This path will be eventually improved later but as it's only used on SI (or with RADV_DEBUG=noibs), I'm not sure if that matters much.
