Subject: [Qemu-devel] [RFC PATCH 0/7] x86: SMRAM implementation for KVM
Date: Fri, 15 May 2015 18:36:56 +0200	[thread overview]
Message-ID: <1431707823-51230-1-git-send-email-pbonzini@redhat.com> (raw)

This is the final piece of x86 SMM implementation, tested with PIIX
(low SMRAM) and Q35 (high SMRAM).

There is a problem---it has an awful layering violation in patch 5,
and an only slightly better one in patch 6.

If anyone has ideas, please speak up.  Note that it is not possible
to call KVM_SET_USER_MEMORY_REGION every time you enter or leave SMM,
because that would only work for single-processor virtual machines.

Andrew Jones (1):
  kvm-all: put kvm_mem_flags to more work

Paolo Bonzini (6):
  kvm-all: remove useless typedef
  kvm-all: move KVMState definitions to kvm_int.h
  kvm-all: add KVM address space
  memory: add kvm_mem_flags to MemoryRegion
  i386: disable the region in /machine/smram when SMRAM is open
  kvm-i386: register SMRAM regions with KVM_MEM_X86_SMRAM
