[Qemu-devel] Call for GSoC 2017 mentors & project ideas

QEMU will be applying to Google Summer of Code again this year. Do you want to help some of the most talented university students begin contributing to open source by working on our codebase and joining our community? We need to put together a list of project ideas by February 9:

[Qemu-devel] [PATCH 2/3] numa: Remove the numa_post_machine_init function

Current default way of seting the CPUState::numa_node in the numa_post_machine_init() and calling it in vl.c:main() would make the data incorrect in case on cold/hot-plug CPUs. Now, we move it to the qom/cpu.c:cpu_common_realizefn(). So, Here we remove it. Signed-off-by: Dou Liyang

[Qemu-devel] [PATCH v3] hw/core/null-machine: Add the possibility to instantiate a CPU and RAM

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
