[PATCH] iommu: spapr_tce: Disable compile testing to fix build on book3s_32 config
Although SPAPR_TCE_IOMMU itself can be compile tested on certain PowerPC
configurations, its presence makes arch/powerpc/kvm/Makefile to select
modules which do not build in such configuration.
The arch/powerpc/kvm/ modules use kvm_arch.spapr_tce_tables which exists
only with CONFIG_PPC_BOOK3S_64. However these...

[RFC PATCH] virtio_ring: Use DMA API if guest memory is encrypted
...address it wants. Will that corrupt kernel
> memory?
Not needing address translation doesn't necessarily mean that there's no
IOMMU. On powerpc we don't use VIRTIO_F_ACCESS_PLATFORM but there's
always an IOMMU present. And we also support VFIO drivers. The VFIO API
for pseries (sPAPR section in Documentation/vfio.txt) has extra ioctls
to program the IOMMU.
For our use case, we don't need address translation because we set up an
identity mapping in the IOMMU so that the device can use guest physical
addresses.
If the guest kernel is concerned that an unprivileged driver co...

How to connect to console of domain on PowerPC?
Hi,
I tried to use libvirt to run KVM/QEMU on Freescale PowerPC platforms.
So far there's only one serial device (spapr-vty) defined in QEMU to work as console for IBM PSeries platform.
There's no serial device support in QEMU for Freescale PowerPC (ePAPR).
libvirt/src/qemu/qemu_command.c
/* This function generates the correct '-device' string for character
* devices of each architecture.
