From 7839b693640dc53bd97279b99b1a2747883ada2a Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 5 Oct 2017 14:51:15 +0200 Subject: [PATCH 03/11] vga: Start cutting out non-32bpp conversion support RH-Author: Gerd Hoffmann Message-id: <20171005145119.15277-4-kraxel@redhat.com> Patchwork-id: 76825 O-Subject: [RHEL-7.5 qemu-kvm PATCH 3/7] vga: Start cutting out non-32bpp conversion support Bugzilla: 1501294 RH-Acked-by: Dr. David Alan Gilbert RH-Acked-by: Thomas Huth RH-Acked-by: Miroslav Rezanina From: Benjamin Herrenschmidt Nowadays, we either share a surface with the host, or we create a 32bpp ARGB console surface. So we only need to draw/convert to 32bpp, enabling us to remove all but one instance of vga_template.h inclusion (to be further cleaned up), rgb_to_pixel_* etc...
