Fix some of the nasty TCG race conditions and crashes by implementing cpu_exit() as setting a flag which is checked at the start of each TB. This avoids crashes if a thread or signal handler calls cpu_exit() while the execution thread is itself modifying the TB graph (which may happen in system emulation mode as well as in linux-user mode with a multithreaded guest binary). This fixes the crashes seen in LP:668799; however there are another class of crashes described in LP:1098729 which stem from the fact that in linux-user with a multithreaded guest all threads will use and modify the same global TCG date structures (including the generated code buffer) without any kind of locking. This means that multithreaded guest binaries are still in the "unsupported" category.

If tcg_qemu_tb_exec() returns a value whose low bits don't indicate a link to an indexed next TB, this means that the TB execution never started (eg because the instruction counter hit zero). In this case the guest PC has to be reset to the address of the start of the TB. Refactor the cpu-exec code to make all tcg_qemu_tb_exec() calls pass through a wrapper function which does this restoration if necessary. Note that the apparent change in cpu_exec_nocache() from calling cpu_pc_from_tb() with the old TB to calling it with the TB returned by do_tcg_qemu_tb_exec() is safe, because in the nocache case we can guarantee that the TB we try to execute is not linked to any others, so the only possible returned TB is the one we started at. That is, we should arguably previously have included in cpu_exec_nocache() an assert(next_tb & ~TB_EXIT_MASK) == tb), since the API requires restore from next_tb but we were using tb.

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. We can factor out the TYPE_M25P80 abstraction into a header on a demand basis.

In QEMU emulation, there is no functional difference between the ARM mpcore private timers and watchdogs. Removed all the distinction between the two from arm_mptimer.c and converted it to be just the mptimer. a9mpcore and arm11mpcore just instantiate the same mptimer object twice to get both timer and WDT. If in the future we want to make the WDT functionally different then we can use either QOM hierarchy to derive WDT from from mptimer, or we can add a property "is-wdt" or some such.

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.

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.

In the current implementation of qemu, running without a network backend will cause the queue to grow unbounded when the guest is transmitting traffic. This patch fixes the problem by implementing bounded size NetQueue, used with an arbitrary limit of 10000 packets, and dropping packets when the queue is full _and_ the sender does not pass a callback. The second condition makes sure that we never drop packets that contains a callback (which would be tricky, because the producer expects the callback to be run when all previous packets have been consumed; so we cannot run it when the packet is dropped). If documentation is correct, producers that submit a callback should stop sending when their packet is queued, so there is no real risk that the queue exceeds the max size by large values.

When frontend and backend are connected through a hub as below (showing only one direction), and the frontend (or in general, all output ports of the hub) cannot accept more traffic, the backend queues packets in queue-A. When the frontend (or in general, one output port) becomes ready again, quemu tries to flush packets from queue-B, which is unfortunately empty. e1000.0 <--[queue B]-- hub0port0(hub)hub0port1 <--[queue A]-- tap.0 To fix this i propose to introduce a new function net_hub_flush() which is called when trying to flush a queue connected to a hub.
