This patchset enables support for nested (two stage) translations in the SMMU in the virt and sbsa-ref boards.
Patch 1 is Cornelia's compat-machine machinery patch, which we need to make this change only happen for virt-9.2 and later; patch 2 is a trivial "missing comment update" change; patches 3 and 4 are the board changes. Enabling nested support should be transparent to guests, which will only enable stage 2 if they actually want it. thanks -- PMM Cornelia Huck (1): hw: add compat machines for 9.2 Peter Maydell (3): hw/arm/smmuv3: Update comment documenting "stage" property hw/arm/virt: Default to two-stage SMMU from virt-9.2 hw/arm/sbsa-ref: Use two-stage SMMU include/hw/arm/virt.h | 1 + include/hw/boards.h | 3 +++ include/hw/i386/pc.h | 3 +++ hw/arm/sbsa-ref.c | 1 + hw/arm/smmuv3.c | 1 + hw/arm/virt.c | 19 +++++++++++++++++-- hw/core/machine.c | 3 +++ hw/i386/pc.c | 3 +++ hw/i386/pc_piix.c | 15 ++++++++++++--- hw/i386/pc_q35.c | 13 +++++++++++-- hw/m68k/virt.c | 11 +++++++++-- hw/ppc/spapr.c | 17 ++++++++++++++--- hw/s390x/s390-virtio-ccw.c | 14 +++++++++++++- 13 files changed, 91 insertions(+), 13 deletions(-) -- 2.34.1
