From 43f4420fba1c9855c0f127143a4ed13b170ac49b Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Mon, 18 Jan 2016 16:19:32 +0100 Subject: [PATCH] gallium: add indirect compute parameters to pipe_grid_info MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Like indirect draw, we need to store a resource and an offset that needs to be 4 byte aligned. When indirect is used, the size of the grid (in blocks) is stored with three 32-bit integers.
