2009-12-20user_only: compile everything with -fpieKirill A. Shutemov1-0/+3
We really need compile _all_ sources for user target with -fpie when use --enable-user-pie. It's regression introduced by commit add16157d72454. Signed-off-by: Kirill A.

2009-12-12Do not abort on qemu_malloc(0) in production buildsAnthony Liguori1-1/+17
qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior. Unfortunately, there is good reason to believe that within qemu, there are a number of, so far, undetected places that assume size=0 can be safely passed. Since we do not want to abort unnecessarily in production builds, return qemu_malloc(1) whenever the version file indicates that this is a production build.

2009-12-05Add KVM support for S390xAlexander Graf1-1/+3
S390x was one of the first platforms that received support for KVM back in the day. Unfortunately until now there hasn't been a qemu implementation that would enable users to actually run guests. So let's include support for KVM S390x in qemu! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-12-02configure: use correct cflags in compiler checksMichael S. Tsirkin1-20/+21
linux-user build on fedora 11 breaks because fallocate is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 are specified, which is what QEMU uses. We do have a configure check to catch this and disable fallocate, however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in script *after* all compiler checks: so during checks we were not running compiler with same flags that we used for build later. Fix this by moving QEMU_CFLAGS to before compiler checks, and using comple_prog when checking for fallocate. This also fixes the fact that we do some compiler checks while assigning the flags, right below a comment that says "no cc tests beyond this point". Signed-off-by: Michael S.

2009-12-01tcg: initial mips supportAurelien Jarno1-1/+6
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org> A few words about design choices: * Two registers, at and t0, are reserved for TCG internal use. They are useful for bswap and 64-bit ops. * Most ops supports a constant argument with value 0, which is actually mapped to the zero register. * While the at register is available for constant loading, ops only support a limited range of constants. TCG does a better job doing the register allocation and constant loading by itself. There are plenty of registers available anyway. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-11-22Makefile dependencies for device configsPaul Brook1-4/+0
Add makefile dependencies for target specific device configs. These will copy the default config if none exists, obsoleting the old configure time code. If a config already exists but is older than the default then print a warning. Also remove config-devices.h. Code does not and should not care which devices are being built.

2009-11-09Configurable block format whitelistMarkus Armbruster1-0/+7
We have code for a quite a few block formats. While I trust that all of these formats are useful at least for some people in some circumstances, some of them are of a kind that friends don't let friends use in production. This patch provides an optional block format whitelist, default off. If a whitelist is configured with --block-drv-whitelist, QEMU proper can use only whitelisted formats. Other programs, like qemu-img, are not affected. Drivers for formats off the whitelist still participate in format probing, to ensure all programs probe exactly the same. Without that, QEMU proper would be prone to treat images with a format off the whitelist as raw when the image's format is probed.

2009-11-02Fix the build when srcdir == objdirAnthony Liguori1-3/+3
You would only see this error on a fresh clone when srcdir == objdir. configure will fail because roms/pcbios doesn't exist. git submodule integration doesn't cleanup very well when switching between branches so you'll get an roms/pcbios directory from normal operations if you switch between old branches. Thanks to a mistake in configure, if you build outside of srcdir, you'll also get a valid roms/pcbios. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
