2013-11-21pc: get rid of builtin pvpanic for "-M pc-1.5"Paolo Bonzini
This causes two slight backwards-incompatibilities between "-M pc-1.5" and 1.5's "-M pc": (1) a fw_cfg file is removed with this patch. This is only a problem if migration stops the virtual machine exactly during fw_cfg enumeration. (2) after migration, a VM created without an explicit "-device pvpanic" will stop reporting panics to management. The first problem only occurs if migration is done at a very, very early point (and I'm not sure it can happen in practice for reasonable-size VMs, since it will likely take more time to send the RAM to destination, than it will take for BIOS to scan fw_cfg). The second problem only occurs if the guest panics _and_ has a guest driver _and_ management knows to look at the crash event, so it is mostly theoretical at this point in time. Thus keep the code simple, and pretend it was never broken. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-11-21configure: Explicitly set ARFLAGS so we can build with GNU Make 4.0Peter Maydell
Our rules.mak adds '-rR' to MAKEFLAGS to indicate that we will be explicitly specifying everything and not relying on any default variables or rules. However we were accidentally relying on the default ARFLAGS ("rv"). This went unnoticed because of a bug in GNU Make 3.82 and earlier which meant that adding -rR to MAKEFLAGS only affected submakes, not the currently running instance. Explicitly set ARFLAGS in config-host.mak, in the same way we handle CFLAGS and LDFLAGS; this will allow us to work with Make 4.0. Thanks to Paul Smith for analyzing this bug for us.

2013-11-21sun4m: Add FCode ROM for TCX framebufferMark Cave-Ayland
Upstream OpenBIOS now implements SBus probing in order to determine the contents of a physical bus slot, which is required to allow OpenBIOS to identify the framebuffer without help from the fw_cfg interface. SBus probing works by detecting the presence of an FCode program (effectively tokenised Forth) at the base address of each slot, and if present executes it so that it creates its own device node in the OpenBIOS device tree. The FCode ROM is generated as part of the OpenBIOS build and should generally be updated at the same time.

2013-11-19migration: drop MADVISE_DONT_NEED for incoming zero pagesPeter Lieven
The madvise for zeroed out pages was introduced when every transferred zero page was memset to zero and thus allocated. Since commit 211ea740 we check for zeroness of a target page before we memset it to zero. Additionally we memmap target memory so it is essentially zero initialized (except for e.g. option roms and bios which are loaded into target memory although they shouldn't). It was reported recently that this madvise causes a performance degradation in some situations. As the madvise should only be called rarely and if it's called it is likely on a busy page (it was non-zero and changed to zero during migration) drop it completely.

There was a misconception that a stop bit is required between a compare and the branch that uses the predicate set by the compare. This lead to the usage of an extra bundle in which to perform the compare. The extra bundle left room for constants to be loaded for use with the compare insn. If we pack the compare and the branch together in the same bundle, then there's no longer any room for non-zero constants. At which point we can eliminate half the function by not handling them.

2013-11-14block/drive-mirror: Check for NULL backing_hdMax Reitz
It should be possible to execute the QMP "drive-mirror" command in "none" sync mode and "absolute-paths" mode even for block devices lacking a backing file. "absolute-paths" does in fact not require a backing file to be present, as can be seen from the "top" sync mode code path. "top" basically states that the device should indeed have a backing file - however, the current code catches the case if it doesn't and then simply treats it as "full" sync mode, creating a target image without a backing file (in "absolute-paths" mode). Thus, "absolute-paths" does not imply the target file must indeed have a backing file. Therefore, the target file may be left unbacked in case of "none" sync mode as well, if the specified device is not backed either. Currently, qemu will crash trying to dereference the backing file pointer since it assumes that it will always be non-NULL in that case ("none" with "absolute-paths").

pci, pc, virtio bug fixes This reverts PCI master abort support - we'll want it eventually but it exposes too many core bugs to be safe for 1.7. This also reverts a recent exec.c change that was an attempt to work-around some of these core bugs. Also included are small fixes in pc and virtio, and a core loader fix for PPC bamboo.
