ACPI table HMAT has been introduced, QEMU now builds HMAT tables for

PAPR guests have a certain "Real Mode Area" - a subsection of memory
which can be accessed when in guest real mode (that is, with the MMU
"off" from the guest point of view). This is advertised to the guest
in the device tree.
We want to make the RMA as large as we can, to allow for flexibility
The Real Mode Area (RMA) is the part of memory which a guest can access
when in real (MMU off) mode. Of course, for a guest under KVM, the MMU
isn't really turned off, it's just in a special translation mode - Virtual
Real Mode Area (VRMA) - which looks like real mode in guest mode.
The
The Real Mode Area (RMA) needs to fit within Node 0 in NUMA configurations.
We use a helper function spapr_node0_size() to calculate this.

This function calculates the maximum size of the RMA as implied by the
host's page size of structure of the VRMA (there are a number of other
constraints on the RMA size which will supersede this one in many

Hi,
This series failed the docker-quick@centos7 build test. Please find the testing

locally.

PAPR allows the interrupt controller used on a POWER9 machine (XICS or
XIVE) to be selected by the guest operating system, by using the
ibm,client-architecture-support (CAS) feature negotiation call.
Currently, if the guest selects an interrupt controller different from the
one selected at
Hi folks,
Right now some smbios fields are hard coded (like CPU nominal
frequency), and some can be opted in, but there is no feasible way to
present real backend hardware information to the front. In some
scenario, the users of virtual machines may not be happy to see an
unknown CPU model

In currently implementation there will be a memory leak when
nbd_client_connect() returns error status. Here is an easy way to
reproduce:
1. run qemu-iotests as follow and check the result with asan:
./check -raw 143
Following is the asan output backtrack:

This series contains several cleanups to the handling of the
ibm,client-architecture-support firmware call used for boot time
feature negotiation between the guest OS and the firmware &
hypervisor.
Mostly it's just internal polish, but one significant user visible
change is that we no longer
Previously, spapr_build_fdt() constructed the device tree in a fixed
buffer of size FDT_MAX_SIZE. This is a bit inflexible, but more
importantly it's awkward for the case where we use it during CAS. In
that case the guest firmware supplies a buffer and we have to
awkwardly check that what we
spapr_ovec_diff(ov, old, new) has somewhat complex semantics. ov is set
to those bits which are in new but not old, and it returns as a boolean
whether or not there are any bits in old but not new.
It turns out that both callers only care about the second, not the first.
This is basically

The BDRVNBDState cleanup code is common in two places, add
nbd_free_bdrvstate_prop() function to do these cleanups (suggested by
Stefano Garzarella).

Add -numa hmat-cache option to provide Memory Side Cache Information.
These memory attributes help to build Memory Side Cache Information
Structure(s) in ACPI Heterogeneous Memory Attribute Table (HMAT).
Before using hmat-cache option, enable HMAT with -machine hmat=on.

The virtual timebase register (VTB) is a 64-bit register which
increments at the same rate as the timebase register, present on POWER8
and later processors.
The register is able to be read/written by the hypervisor and read by
the supervisor. All other accesses are

The spr TBU40 is used to set the upper 40 bits of the timebase
register, present on POWER5+ and later processors.
This register can only be written by the hypervisor, and cannot be read.
