From 5bd5ec6a0f1821a8ac5e1d4ee59b324588adc2d5 Mon Sep 17 00:00:00 2001 From: Charmaine Lee Date: Tue, 18 Apr 2017 15:55:59 -0700 Subject: [PATCH] svga: fix format for screen target This patch revises the fix in commit 606f13afa31c9f041a68eb22cc32112ce813f944 to properly translate the surface format for screen target. Instead of changing the svga format for PIPE_FORMAT_B5G6R5_UNORM to SVGA3D_R5G6B5 for all texture surfaces, this patch only restricts SVGA3D_R5G6B5 for screen target surfaces. This avoids rendering failures when specify a non-vgpu10 format in a vgpu10 context with software renderer. Fixes piglit failures spec@!opengl 1.1@draw-pixels, spec@!opengl 1.1@teximage-colors gl_r3_g3_b2 spec@!opengl 1.1@texwrap formats Tested Xorg with 16bits depth. Also tested with MTT piglit, MTT glretrace.
