2017-01-24gdbstub.c: fix GDB connection segfault caused by empty machinesZiyue Yang
This patch is to fix the segmentation fault caused by attaching GDB to a QEMU instance initialized with "-M none" option. The bug can be reproduced by > ./qemu-system-x86_64 -M none -nographic -S -s and attach a GDB to it by > gdb -ex 'target remote :1234 The segmentation fault was originally caused by trying to read the information about CPU when communicating with GDB. However, it's impossible for any control flow to exist on an empty machine, nor can CPU's be hot plugged to an empty machine later by QOM commands. So I think simply disabling GDB connections on empty machines makes sense.

2017-01-24scsi-disk: add 'fall through' comment to switch VERIFY casesPeter Maydell
Commit 166dbda7e131 added some extra cases to a switch() such that the existing code is intended to fall through the new case statements. It's clear from the commit that this is intentional, but less clear to subsequent readers of the code, and not clear at all to static analysis tools like Coverity. Add a /* fall through */ comment to indicate the intent. (Fixes CID 1368287.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

2017-01-24win32: use glib gpoll if glib >= 2.50Marc-André Lureau
A fix has been committed in upstream glib commit 210a9796f78eb90f76f1bd6a304e9fea05e97617. (See also related bug https://bugzilla.gnome.org/show_bug.cgi?id=764415) It is desirable to use the glib version instead of qemu copy, since it provides more debugging facilities (G_MAIN_POLL_DEBUG etc), and hopefully has a better maintainance.

2017-01-23hw/core/null-machine: Add the possibility to instantiate a CPU and RAMThomas Huth
Sometimes it is useful to have just a machine with CPU and RAM, without any further hardware in it, e.g. if you just want to do some instruction debugging for TCG with a remote GDB attached to QEMU, or run some embedded code with the "-semihosting" QEMU parameter. qemu-system-m68k already features a "dummy" machine, and xtensa a "sim" machine for exactly this purpose. All target architectures have nowadays also a "none" machine, which would be a perfect match for this, too - but it currently does not allow to add CPU and RAM yet. Thus let's add these possibilities in a generic way to the "none" machine, too, so that we hopefully do not need additional "dummy" machines in the future anymore (and maybe can also get rid of the already existing "dummy"/"sim" machines one day). Note that the default behaviour of the "none" machine is not changed, i.e. no CPU and no RAM is instantiated by default. You have explicitely got to specify the CPU model with "-cpu" and the amount of RAM with "-m" to get these new features.

2017-01-23vl: Ensure the numa_post_machine_init func in the appropriate locationDou Liyang
In the numa_post_machine_init(), we use CPU_FOREACH macro to set all CPUs' namu_node. So, we should make sure that we call it after Qemu has already initialied all the CPUs. As we all know, the CPUs can be created by "-smp"(pc_new_cpu) or "-device"(qdev_device_add) command. But, before the device init, Qemu execute the numa_post_machine_init earlier. It makes the mapping of NUMA nodes and CPUs incorrect. The patch move the numa_post_machine_init func in the appropriate location.

2017-01-23i386: Remove AMD feature flag aliases from Opteron modelsEduardo Habkost
When CPU vendor is set to AMD, the AMD feature alias bits on CPUID[0x80000001].EDX are already automatically copied from CPUID[1].EDX on x86_cpu_realizefn(). When CPU vendor is Intel, those bits are reserved and should be zero. On either case, those bits shouldn't be set in the CPU model table. Commit 726a8ff68677d8d5fba17eb0ffb85076bfb598dc removed those bits from most CPU models, but the Opteron_* entries still have them. Remove the alias bits from Opteron_* too. Add an assert() to x86_register_cpudef_type() to ensure we don't make the same mistake again.
