From c94b70a1781b8fb65be24b7e3a72462426cd86c4 Mon Sep 17 00:00:00 2001 From: Timur Kristóf Date: Fri, 31 May 2019 18:43:20 +0200 Subject: st/nine: Use tgsi_to_nir when preferred IR is NIR. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch allows nine to read the preferred IR from pipe caps and use NIR when that is preferred by the driver, by calling tgsi_to_nir. Also adds some debug options that allow overriding it.
