Subject: [Qemu-devel] [RFC PATCH 0/6] support KVM_MEM_INCOHERENT
Date: Fri,  6 Mar 2015 13:53:32 -0500	[thread overview]
Message-ID: <1425668018-3649-1-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1425667780-3449-1-git-send-email-drjones@redhat.com>

Add support for the new KVM_MEM_INCOHERENT flag, and flag
appropriate memory. (Only flags vram for now.)

Patch 6/6 doesn't appear to be complete. While the VGA output is
99% corruption free, it's not perfect, so it's missing flushes
somewhere... 

Andrew Jones (6):
  memory: add incoherent cache flag
  HACK: linux header update
  kvm-all: put kvm_mem_flags to more work
  kvm-all: set KVM_MEM_INCOHERENT
  vga: flag vram as incoherent
  memory: add clear_cache_to_poc
