From c778ff571489adc577f9b7395940281aa3af4b6a Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Tue, 6 Dec 2016 14:52:37 +0800 Subject: [PATCH] qemu: packaging target {x86_64,arm}-softmmu and friends At the moment, only build these softmmu emulators for x86_64 and sunxi target. The decision was made for the following reasons - It seems that interests of virtualization with qemu are mostly from x86, and ARM recently. - x86, sunxi boards/boxes capable of running qemu with accel=kvm are more widely available - Not all host, target combinations of qemu works, or even compiles - Extra maintenance work and server resources Test results are as the following - Nested vmx works: lede-qemu-x86_64-kvm on lede-qemu-x86_64-kvm - KVM on Cubieboard2 works - tcg with malta works: lede-qemu-malta-tcg on lede-qemu-malta-tcg. But it's too slow to be useful thus not included in this version - mips64 host does not compile Signed-off-by: Yousong Zhou --- utils/qemu/Makefile | 191 ++++++++++++++++-- utils/qemu/files/bridge.conf | 1 + .../0001-allow-disable-fortify-source.patch | 11 + ...setting-language-type-for-_asm-files.patch | 11 + .../0003-disable-avx2_opt-with-musl.patch | 14 ++ ...4-pixman-fix-detection-of-mips-dspr2.patch | 10 + .../0005-pixman-arm-neon-assembler-fix.patch | 17 ++ .../0006-libvixl-cxx-macro-isnan.patch | 55 +++++ 8 files changed, 292 insertions(+), 18 deletions(-) create mode 100644 utils/qemu/files/bridge.conf create mode 100644 utils/qemu/patches/0001-allow-disable-fortify-source.patch create mode 100644 utils/qemu/patches/0002-setting-language-type-for-_asm-files.patch create mode 100644 utils/qemu/patches/0003-disable-avx2_opt-with-musl.patch create mode 100644 utils/qemu/patches/0004-pixman-fix-detection-of-mips-dspr2.patch create mode 100644 utils/qemu/patches/0005-pixman-arm-neon-assembler-fix.patch create mode 100644 utils/qemu/patches/0006-libvixl-cxx-macro-isnan.patch diff --git a/utils/qemu/Makefile b/utils/qemu/Makefile index 15fa72b17..c512dec32 100644 --- a/utils/qemu/Makefile +++ b/utils/qemu/Makefile @@ -18,6 +18,7 @@ PKG_LICENSE_FILES:=LICENSE tcg/LICENSE PKG_MAINTAINER:=Yousong Zhou PKG_INSTALL:=1 +PKG_USE_MIPS16:=0 include $(INCLUDE_DIR)/uclibc++.mk include $(INCLUDE_DIR)/package.mk @@ -27,15 +28,100 @@ define Package/qemu-ga CATEGORY:=Utilities TITLE:=QEMU Guest Agent URL:=http://www.qemu.org - DEPENDS:=+glib2 +libpthread $(CXX_DEPENDS) +librt + DEPENDS:= +glib2 $(CXX_DEPENDS) endef define Package/qemu-ga/description -This package contains the QEMU Guest Agent daemon + This package contains the QEMU Guest Agent daemon +endef + +define Package/qemu-ga/install + $(INSTALL_DIR) $(1)/usr/bin + $(INSTALL_BIN) $(PKG_INSTALL_DIR)/usr/bin/qemu-ga $(1)/usr/bin + $(INSTALL_DIR) $(1)/etc/init.d + $(INSTALL_BIN) ./files/qemu-ga.init $(1)/etc/init.d/qemu-ga + $(INSTALL_DIR) $(1)/etc/hotplug.d/virtio-ports + $(INSTALL_BIN) ./files/virtio-ports.hotplug $(1)/etc/hotplug.d/virtio-ports/qemu-ga +endef + +define Package/qemu-blobs + SECTION:=utils + CATEGORY:=Utilities + TITLE:=QEMU blobs of BIOS, VGA BIOS and keymaps + URL:=http://www.qemu.org + DEPENDS:= +endef + +define Package/qemu-blobs/install + $(INSTALL_DIR) $(1)/usr/share/qemu + $(CP) $(PKG_INSTALL_DIR)/usr/share/qemu/* $(1)/usr/share/qemu +endef + +define Package/qemu-bridge-helper + SECTION:=utils + CATEGORY:=Utilities + TITLE:=QEMU bridge helper + URL:=http://www.qemu.org + DEPENDS:=+glib2 $(CXX_DEPENDS) +endef + +define Package/qemu-bridge-helper/install + $(INSTALL_DIR) $(1)/usr/lib/ + $(INSTALL_BIN) $(PKG_INSTALL_DIR)/usr/lib/qemu-bridge-helper $(1)/usr/lib + $(INSTALL_DIR) $(1)/etc/qemu + $(INSTALL_DATA) ./files/bridge.conf $(1)/etc/qemu endef PKG_CONFIG_DEPENDS += CONFIG_PACKAGE_qemu-ga +# Naming rules used in qemu Makefile.target +define qemu-prog_ + $(if $(filter %-softmmu,$(1)), \ + $(patsubst %-softmmu,qemu-system-%,$(1)), \ + $(error unknown qemu target $(1)) \ + ) +endef +qemu-prog = $(strip $(call qemu-prog_,$(1))) + +# Why libfdt was enabled for all softmmu targets: according to qemu's +# configure script, libfdt is only strictly required for the following targets +# and is optional for others.
