From 0143117eb5e6233fdeff3b679492b51148cc8f85 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 24 Mar 2010 15:47:18 +0100 Subject: [PATCH 07/39] spice: simple display With that patch applied you'll actually see the guests screen in the spice client. This does *not* bring qxl and full spice support though. This is basically the qxl vga mode made more generic, so it plays together with any qemu-emulated gfx card. You can display stdvga or cirrus via spice client. You can have both vnc and spice enabled and clients connected at the same time. --- Makefile.objs | 2 +- qemu-spice.h | 1 + spice-display.c | 394 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ spice-display.h | 52 ++++++++ vl.c | 7 +- 5 files changed, 454 insertions(+), 2 deletions(-) create mode 100644 spice-display.c create mode 100644 spice-display.h diff --git a/Makefile.objs b/Makefile.objs index 023a0dc..d05643f 100644 --- a/Makefile.objs +++ b/Makefile.objs @@ -89,7 +89,7 @@ common-obj-y += pflib.o common-obj-$(CONFIG_BRLAPI) += baum.o common-obj-$(CONFIG_POSIX) += migration-exec.o migration-unix.o migration-fd.o -common-obj-$(CONFIG_SPICE) += spice.o spice-input.o +common-obj-$(CONFIG_SPICE) += spice.o spice-input.o spice-display.o audio-obj-y = audio.o noaudio.o wavaudio.o mixeng.o audio-obj-$(CONFIG_SDL) += sdlaudio.o diff --git a/qemu-spice.h b/qemu-spice.h index ceb3db2..f061004 100644 --- a/qemu-spice.h +++ b/qemu-spice.h @@ -13,6 +13,7 @@ extern int using_spice;
