git://github.com/jljusten/qemu.git kvm-flash-v4 Utilize KVM_CAP_READONLY_MEM to support PC system flash emulation with KVM.
v4: * With a machine type of isapc, don't mark the BIOS as read-only. isapc + seabios will not boot if the BIOS is read-only. This matches the current behavior of isapc with KVM, which is the only mode under which isapc currently works. 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 (6): isapc: Fix non-KVM qemu boot (read/write memory for isapc BIOS) 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 hw/block/pc_sysfw.c | 64 ++++++++++++++++++++++++++++++----------------- hw/block/pflash_cfi01.c | 2 ++ hw/i386/pc_piix.c | 5 ++++ include/hw/i386/pc.h | 4 --- include/sysemu/kvm.h | 10 ++++++++ kvm-all.c | 42 ++++++++++++++++++++++++------- kvm-stub.c | 1 + 7 files changed, 92 insertions(+), 36 deletions(-) -- 1.7.10.4
