From: Samuel Pitoiset Date: Thu, 19 Apr 2018 11:39:17 +0000 (+0200) Subject: Revert "radv: Don't store buffer references in the descriptor set." X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7bd5367546971f65c8210c0b44b8f21c0b8811c4;p=mesa.git Revert "radv: Don't store buffer references in the descriptor set." In order to reduce a performance regression introduced by 4b13fe55a4 ("radv: Keep a global BO list for VkMemory."), we are going to maintain two different paths. One when VK_EXT_descriptor_indexing is enabled by the application because we need to have a global BO list, and one (the old one) when it's not enabled. With Talos on Polaris, the global BO list reduces performance by 10% which is too much for me. This reverts commit ab6cadd3ecc7fbdd9079808b407674e0b19c52f0.
