From f17948a30a339b4196806de795c25a29058ecdc2 Mon Sep 17 00:00:00 2001 From: Nicolas Koch Date: Tue, 20 Sep 2016 17:37:36 +0200 Subject: [PATCH] anv: Check for VK_WHOLE_SIZE in anv_CmdFillBuffer From the Vulkan spec: Size is the number of bytes to fill, and must be either a multiple of 4, or VK_WHOLE_SIZE to fill the range from offset to the end of the buffer. If VK_WHOLE_SIZE is used and the remaining size of the buffer is not a multiple of 4, then the nearest smaller multiple is used.
