From 82810d3b660dfeef53a18c0d48914783e2999b2a Mon Sep 17 00:00:00 2001 From: Stanislaw Halik Date: Thu, 4 Dec 2014 16:52:22 +0100 Subject: [PATCH] st/nine: Hack to generate resource if it doesn't exist when getting view Buffers in the MANAGED pool are supposed to have the content in a ram buffer, a copy in VRAM if there is enough memory (driver manages memory and decide when to delete the buffer in VRAM). This is not implemented properly in nine, and a VRAM copy is going to be created when the RAM memory is filled, and the VRAM copy will get synced with the RAM memory updates. Due to some issues (in the implementation or in app logic), it can happen we try to create a sampler view of the resource while we haven't created the VRAM resource. This hack creates the resource when we hit this case, which prevents crashing, but doesn't help with the resource content. This fixes several games crashing at launch.
