2013-03-08pseries: Add compatible property to root of device treeDavid Gibson
Currently, for the pseries machine the device tree supplied by qemu to SLOF and from there to the guest does not include a 'compatible property' at the root level. Usually that works fine, since in this case the compatible property doesn't really give any information not already found in the 'device_type' or 'model' properties. However, the lack of 'compatible' confuses the bootloader install in the SLES11 SP2 and SLES11 SP3 installers. This patch therefore adds a token 'compatible' property to work around that.

2013-03-08Save memory allocation in the elf loaderFabien Chouteau
The current elf loader uses too much memory. For example, I have a executable with a bss section of 400 MB and I set the ram size to 512 MB. Qemu uses about 780MB of RAM (which is fine), but there's a peak at 1.6 GB during initialization (this is not fine). This patch fixes two things: 1) do not allocate each elf program twice. 2) do not allocate memory for areas that are only zeros. For this we need a new field in Rom: "datasize" which is the size of the allocated data. If datasize is less than romsize, it means that the area from datasize to romsize is filled with zeros.

The BIT6 of Status Register(SR): SR[6] behaves the same as R/B# pin SR[6] = 0 indicates the device is busy; SR[6] = 1 means the device is ready Some NAND flash controller (i.e. ftnandc021) relies on the SR[6] to determine if the NAND flash erase/program is success or error timeout.

2013-03-04dataplane: remove EventPoll in favor of AioContextPaolo Bonzini
During the review of the dataplane code, the EventPoll API morphed itself (not concidentially) into something very very similar to an AioContext. Thus, it is trivial to convert virtio-blk-dataplane to use AioContext, and a first baby step towards letting dataplane talk directly to the QEMU block layer. The only interesting note is the value-copy of EventNotifiers. At least in my opinion this is part of the EventNotifier API and is even portable to Windows. Of course, in this case you should not close the notifier's underlying file descriptors or handle with event_notifier_cleanup.

2013-02-28m25p80.c: Use QOM classes for part differentiationPeter Crosthwaite
Currently, M25P80 uses an object property to differentiate between flash parts. Changed this over to use QOM sub-classes - the actual names of the different parts are used to create a set of dynamic classes which passes the part info as class data. The object no longer needs to search the known_devices table for itself, instead it just gets its info from its own class. Kept the intermediate class definition private to m25p80.c for the moment, as the expectation is parts will only be added as new entries in the table.

2013-02-28hw/pflash_cfi01: Treat read in unknown command state as readPeter Maydell
The code for handling the default "unknown command state" case in pflash_read in pflash_cfi01.c comments "reset state & treat it as a read". However the code doesn't actually do this. Moving the default case to the top of the switch so it can fall through into the read case brings this file into line with pflash_cfi02 and makes the code behave as the comments suggest. The pflash_cfi01 code has always had this bug -- it was presumably introduced when the original author copied the cfi02 code and rearranged the order of the switch statement without noticing that the default case relied on the fall-through.

This patch addresses the issue fully described here: http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01804.html Linux kernels prior to 2.6.36 do not disable the PCI device during enumeration process. Since lower and higher parts of a 64bit BAR are programmed separately this leads to qemu receiving a request to occupy a completely wrong address region for a short period of time. We have found that the boot process screws up completely if kvm-apic range is overlapped even for a short period of time (it is fine for other regions though). This patch raises the priority of the kvm-apic memory region, so it is never pushed out by PCI devices. The patch is quite safe as it does not touch memory manager.

QEMU 1.3 does not emulate the link auto negotiation, so if migrate to a 1.3 machine during link auto negotiation, the guest link will be set to down. Fix this by just disabling auto negotiation for 1.3 and older. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-02-27net: reduce the unnecessary memory allocation of multiqueueJason Wang
Edivaldo reports a problem that the array of NetClientState in NICState is too large - MAX_QUEUE_NUM(1024) which will wastes memory even if multiqueue is not used. Instead of static arrays, solving this issue by allocating the queues on demand for both the NetClientState array in NICState and VirtIONetQueue array in VirtIONet. Tested by myself, with single virtio-net-pci device. The memory allocation is almost the same as when multiqueue is not merged.

2013-02-26vhost: memory sync fixesMichael S. Tsirkin
This fixes two bugs related to memory sync during migration: - ram address calculation was missing the chunk address, so the wrong page was dirtied - one after last was used instead of the end address of a region, which might overflow to 0 and cause us to skip the region when the region ends at ~0x0ull.
