From e8fd60e7891c7a931cfa04259762df4adb304049 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Samuel=20Iglesias=20Gons=C3=A1lvez?= Date: Fri, 26 Feb 2016 08:27:48 +0100 Subject: [PATCH] i965: set ctx->Const.MaxViewport{Width,Height} to 32k MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit From ARB_viewport_array spec: " * On GL3-capable hardware the VIEWPORT_BOUNDS_RANGE should be at least [-16384, 16383]. * On GL4-capable hardware the VIEWPORT_BOUNDS_RANGE should be at least [-32768, 32767]." This range is set using ctx->Const.MaxViewportWidth value, so just bump those constants to 32k for gen7+ which can support OpenGL 4.0.
