[Qemu-devel] [RFC PATCH] os-android: Add support to android platform, built by ndk-r10 |
|
Date: |
Tue, 15 Sep 2015 13:11:48 +0800 |
From: Houcheng <address@hidden>
This patch is to build qemu in android ndk tool-chain, and has been tested in
both
x86_64 and x86 android platform with hardware virtualization enabled. This
patch is
composed of three part:
- configure scripts for android
- OS dependent code for android
- kernel headers for android
The configure scripts add cross-compile options for android, define compile
flags and link flags
and call android specific pkg-config. A pseudo pkg-config script is added to
report correct
compile flags for android system.
The OS dependent code for android that implement functions missing in bionic C,
including:
- getdtablesize(): call getrlimit() instead.
- sigtimewait(): call __rt_sigtimewait() instead.
- a_ptsname(): call pstname_r() instead.
- lockf(): not see this feature in android, directly return -1.
- shm_open(): not see this feature in android, directly return -1.
The kernel headers for android include two kernel header missing in android:
scsi/sg.h and
sys/io.h.
How to build android version
----------------------------
1. download the ndk toolchain r10, build the following libraries and install in
your toolchain sysroot:
libiconv-1.14
gettext-0.19
libffi-3.0.12
glib-2.34.3
libpng-1.2.52
pixman-0.30
2. configure the qemu and build:
% export SYSROOT="/opt/android-toolchain64/sysroot"
% CFLAGS=" --sysroot=$SYSROOT -I$SYSROOT/usr/include
-I$SYSROOT/usr/include/pixman-1/" \
./configure --prefix="${SYSROOT}/usr" \
--cross-prefix=x86_64-linux-android- \
--enable-kvm --enable-trace-backend=nop --disable-fdt
--target-list=x86_64-softmmu \
--disable-spice --disable-vhost-net --disable-libiscsi
--audio-drv-list="" --disable-gtk \
--disable-gnutls --disable-libnfs --disable-glusterfs --disable-libssh2
--disable-seccomp \
--disable-usb-redir --disable-libusb
% make -j4
Or, configure qemu to static link version:
% export SYSROOT="/opt/android-toolchain64/sysroot"
% CFLAGS=" --sysroot=$SYSROOT -I$SYSROOT/usr/include
-I$SYSROOT/usr/include/pixman-1/" \
./configure --prefix="${SYSROOT}/usr" \
--cross-prefix=x86_64-linux-android- \
--enable-kvm --enable-trace-backend=nop --disable-fdt
--target-list=x86_64-softmmu \
--disable-spice --disable-vhost-net --disable-libiscsi
--audio-drv-list="" --disable-gtk \
--disable-gnutls --disable-libnfs --disable-glusterfs --disable-libssh2
--disable-seccomp \
--disable-usb-redir --disable-libusb --static
% make -j4

+/*
+ History:
+ Started: Aug 9 by Lawrence Foard (address@hidden), to allow user
+ process control of SCSI devices.
+ Development Sponsored by Killy Corp. NY NY
+Original driver (sg.h):
+* Copyright (C) 1992 Lawrence Foard
+Version 2 and 3 extensions to driver:
+* Copyright (C) 1998 - 2006 Douglas Gilbert
+
+ Version: 3.5.34 (20060920)
+ This version is for 2.6 series kernels.
+
+ For a full changelog see http://www.torque.net/sg
+
+Map of SG verions to the Linux kernels in which they appear:
+ ---------- ----------------------------------
+ original all kernels < 2.2.6
+ 2.1.40 2.2.20
+ 3.0.x optional version 3 sg driver for 2.2 series
+ 3.1.17++ 2.4.0++
+ 3.5.30++ 2.6.0++
+
+Major new features in SG 3.x driver (cf SG 2.x drivers)
+ - SG_IO ioctl() combines function if write() and read()
+ - new interface (sg_io_hdr_t) but still supports old interface
+ - scatter/gather in user space, direct IO, and mmap supported
+
+ The normal action of this driver is to use the adapter (HBA) driver to DMA
+ data into kernel buffers and then use the CPU to copy the data into the
+ user space (vice versa for writes). That is called "indirect" IO due to
+ the double handling of data. There are two methods offered to remove the
+ redundant copy: 1) direct IO and 2) using the mmap() system call to map
+ the reserve buffer (this driver has one reserve buffer per fd) into the
+ user space. Both have their advantages.
+ In terms of absolute speed mmap() is faster. If speed is not a concern,
+ indirect IO should be fine. Read the documentation for more information.
+
+ ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
+ 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
+ That attribute is 0 by default. **
+
+ Historical note: this SCSI pass-through driver has been known as "sg" for
+ a decade. In broader kernel discussions "sg" is used to refer to scatter
+ gather techniques. The context should clarify which "sg" is referred to.
+
+ Documentation
+ =============
+ A web site for the SG device driver can be found at:
+ http://www.torque.net/sg [alternatively check the MAINTAINERS file]
+ The documentation for the sg version 3 driver can be found at:
+ http://www.torque.net/sg/p/sg_v3_ho.html
+ This is a rendering from DocBook source [change the extension to "sgml"
+ or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
+ The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
+ For more information see http://www.torque.net/sg/sg_io.html
+
+ The older, version 2 documents discuss the original sg interface in detail:
+ http://www.torque.net/sg/p/scsi-generic.txt
+ http://www.torque.net/sg/p/scsi-generic_long.txt
+ Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
+
+ Utility and test programs are available at the sg web site. They are
+ packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
+ (for the lk 2.2 series).
