2014-08-20	hostmem: set MPOL_MF_MOVE	Michael S. Tsirkin	1	-1/+1
	When memory is allocated on a wrong node, MPOL_MF_STRICT doesn't move it - it just fails the allocation. A simple way to reproduce the failure is with mlock=on realtime feature. The code comment actually says: "ensure policy won't be ignored" so setting MPOL_MF_MOVE seems like a better way to do this. Cc: qemu-stable@nongnu.org Signed-off-by: Michael S.

2014-08-18	memory: remove memory_region_destroy	Paolo Bonzini	1	-10/+0

2014-06-19	hostmem: allow preallocation of any memory region	Paolo Bonzini	1	-0/+42
	And allow preallocation of file-based memory even without -mem-prealloc. Some care is necessary because -mem-prealloc does not allow disabling preallocation for hostmem-file.

2014-06-19	hostmem: separate allocation from UserCreatable complete method	Hu Tao	1	-0/+20
	This allows the superclass to set various policies on the memory region that the subclass creates. Drops hostmem-ram's complete method accordingly.

2014-06-18	add memdev backend infrastructure	Igor Mammedov	1	-0/+97
	Provides framework for splitting host RAM allocation/ policies into a separate backend that could be used by devices. Initially only legacy RAM backend is provided, which uses memory_region_init_ram() allocator and compatible with every CLI option that affects memory_region_init_ram().
