[Qemu-devel] [PATCH v3 0/5] KVM flash memory support

[Jordan Justen <jordan.l.justen@intel.com>]

git://github.com/jljusten/qemu.git kvm-flash-v3

Utilize KVM_CAP_READONLY_MEM to support PC system flash emulation
with KVM.

v3:
 * Squash patch 2 & 3 based on Xiao's feedback that what I
   was calling a 'workaround' in patch 3 was actually what
   is required by the KVM READONLY memory support.

v2:
 * Remove rom_only from PC_COMPAT_1_4
 * Only enable flash when a pflash drive is created.

Jordan Justen (5):
  kvm: add kvm_readonly_mem_enabled
  kvm: support using KVM_MEM_READONLY flag for readonly regions
  pflash_cfi01: memory region should be set to enable readonly mode
  pc_sysfw: allow flash (-pflash) memory to be used with KVM
  pc_sysfw: change rom_only default to 0
