Utilize KVM_CAP_READONLY_MEM to support PC system flash emulation
with KVM.
v5:
* Remove patch to pflash_cfi01 which enabled readonly mode
* Adjust kvm code to use KVM READONLY support for ranges that
either have the readonly flag set, or for devices with
readable set.
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 (5):
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 regions
pc_sysfw: allow flash (-pflash) memory to be used with KVM
pc_sysfw: change rom_only default to 0
