Instructions for building Android-x86 Marshmallow using mesa/DRM graphics stack. Currently supported is virtio-gpu on QEMU (x86 KVM).

Install dependent packages

This is for ubuntu and assuming your machine is already setup for building kernel and QEMU.

sudo apt-get install libgbm-dev libsdl2-dev libgtk-3-dev libgles2-mesa-dev libpixman-1-dev libtool autoconf

#before qemu-2.6

Build virglrenderer

• git clone git://people.freedesktop.org/~airlied/virglrenderer OR git://git.freedesktop.org/git/virglrenderer
• ./autogen.sh
• HACK: Remove the line with CODE_COVERAGE_RULES in generated Makefile. Alternatively, install the necessary dependency.
• make
• sudo make install

Build QEMU

• fetch current mainline (ver-2.5+)
• HACK: Mouse input with GTK 3.16 and OpenGL appears to be broken. Work-around is edit configure script and force ‘gtk_gl=”no”’.
• ./configure --target-list=x86_64-softmmu --enable-gtk --with-gtkabi=3.0 --enable-kvm
• make

Build Android-x86

• repo init -u git://gitscm.sf.net/gitroot/android-x86/manifest -b marshmallow-x86
• repo sync -j10
• cd external/drm_gralloc
• git fetch x86 virgl
• git checkout x86/virgl
• cd ../..
• cd kernel
• git fetch x86 kernel-4.4
• git checkout x86/kernel-4.4
• cd ..
• lunch Select android_x86_64-eng
• make iso_img -j8

Run QEMU

This is the script I use:

#!/bin/sh

${QEMU_PATH}/qemu-system-x86_64 \
    -enable-kvm \
	-m 1024 \
	-serial stdio \
	-cdrom  ${ANDROID_IMAGE_PATH}/android_x86_64.iso\
	-device virtio-gpu-pci,virgl -display gtk,gl=on

Then press "ctrl-alt-2" to see the GPU-based screen in qemu.

after qemu-2.6

get qemu-2.6 sorce code

From

http://wiki.qemu-project.org/download/qemu-2.6.0.tar.bz2

compile qemu-2.6

tar jxf qemu-2.6.0.tar.bz2
cd qemu-2.6.0
mkdir build
cd build
../configure --target-list=x86_64-softmmu --enable-kvm
make -j8

virgl

if you want to build qemu-with-virgl, you also need install virglrenderer

Build Android-x86-6.0

android-x86-6.0-build-iso
