H_HOME_NODE_ASSOCIATIVITY H-Call returns the associativity domain
designation associated with the identifier input parameter
This fixes a crash when we try to hotplug a CPU in memory-less and
CPU-less numa node. In this case, the kernel tries to online the
node, but without the information provided by this h-call, the node id,
it cannot and the CPU is started while the node is not onlined.
It also removes the warning message from the kernel:
VPHN is not supported. Disabling polling..

From: Alexey Kardashevskiy <aik@ozlabs.ru>
SLOF receives a device tree and updates it with various properties
before switching to the guest kernel and QEMU is not aware of any changes
made by SLOF. Since there is no real RTAS (QEMU implements it), it makes
sense to pass the SLOF final device tree to QEMU to let it implement
RTAS related tasks better, such as PCI host bus adapter hotplug.
Specifially, now QEMU can find out the actual XICS phandle (for PHB
hotplug) and the RTAS linux,rtas-entry/base properties (for firmware
assisted NMI - FWNMI).
This stores the initial DT blob in the sPAPR machine and replaces it
in the KVMPPC_H_UPDATE_DT (new private hypercall) handler.
This adds an @update_dt_enabled machine property to allow backward
migration.
SLOF already has a hypercall since
https://github.com/aik/SLOF/commit/e6fc84652c9c0073f9183
This makes use of the new fdt_check_full() helper. In order to allow
the configure script to pick the correct DTC version, this adjusts
the DTC presense test.

The sm501 model belonged to SH before but that seems to be inactive
now and latest changes were for sam460ex which is the more active user
of this device at the moment so let's adopt sm501 for sam460ex.
Also add device tree and firmware sources and binaries.

These ensure that we consistently handle signed and unsigned extensions correctly
when decoding immediates from instruction opcodes.

These helpers allow us to move FP register values to/from the specified TCGv_i64
argument in the VSR helpers to be introduced shortly.
To prevent FP helpers accessing the cpu_fpr array directly, add extra TCG
temporaries as required.

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
These helpers allow us to move AVR register values to/from the specified TCGv_i64
argument.
To prevent VMX helpers accessing the cpu_avr{l,h} arrays directly, add extra TCG
temporaries as required.

Richard Henderson, David Gibson
From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
These helpers allow us to move VSR register values to/from the specified TCGv_i64
argument.
To prevent VSX helpers accessing the cpu_vsr array directly, add extra TCG
temporaries as required.

This patch breaks something in the libcrypto.
I've been able to reproduce the problem with Fedora 29:
dnf install 'dnf-command(download)'
dnf download --source coreutils-single
rpm --verify coreutils-8.30-7.fc29.src.rpm
error: coreutils-8.30-7.fc29.src.rpm: Header V3 RSA/SHA256 Signature, key ID 429476b4: BAD
error: coreutils-8.30-7.fc29.src.rpm: Header SHA256 digest: BAD (Expected fa042669e74ac435bd5defaa8c2e4efe779a0329c24f2b6377591c53b38aa280 != d6e22527412fafc4aa12882432d0d157e5427097710eeb2d5fce8fbc52a47be6)
error: coreutils-8.30-7.fc29.src.rpm: not an rpm package (or package manifest)
See https://bugzilla.redhat.com/show_bug.cgi?id=1715017
I've tested with origin/master (47fbad45d47af8af784bb12a5719489edcd89b4c) and all the
merged fixes for this patch don't fix this problem.
We should be able to reproduce it on Debian Sid too: it breaks ssh (this is one of the rare binaries using libcrypto on debian).
I've been able to reproduce it with qemu linux-user if I enable PPC_FEATURE2_VEC_CRYPTO in linux-user/elfload.c
(git clone -b linux-user-ppc64-hwcap git@github.com:vivier/qemu.git).
To ease debugging, you can install a Fedora 29 chroot with something like:
curl -o container.tar.xz http://download-ib01.fedoraproject.org/pub/fedora-secondary/releases/29/Container/ppc64le/images/Fedora-Container-Base-29-1.2.ppc64le.tar.xz
tar Jxvf container.tar.xz '*/layer.tar'
mkdir -p chroot/ppc64le/29
cd chroot/ppc64le/29
tar xf $OLDPWD/*/layer.tar
cd -
cp ~/qemu/ppc64le-linux-user/qemu-ppc64le chroot/ppc64le/29/
[use "configure --target-list=ppc64le-linux-user --static --disable-tools" and don't forget to run scripts/qemu-binfmt-conf.sh]
Thanks,
Laurent

One of Anton's VSX patches hasn't landed in master yet and is still queued in
ppc-for-4.1: "target/ppc: Fix lxvw4x, lxvh8x and lxvb16x".
Can you try David's ppc-for-4.1 branch first and let me know if that solves the
issue? If not, I'll take a look at it later in the week when I have a bit more time.
ATB,
Mark.

Great! Also I don't know if you noticed but I posted a roll-up of the VSX fixes for
stable yesterday at
https://lists.gnu.org/archive/html/qemu-devel/2019-06/msg00534.html so these will
eventually make it into the next 4.0 release.
ATB,
Mark.

Hmmm and this is definitely a regression introduced by the same patch as given in the

I bisected and regression comes with:
commit 571fbe6ccd7a159789e5d473e2837d45764197ec

Since the VSX registers are actually a superset of the VMX registers then they
can be represented by the same type. Merge ppc_avr_t into ppc_vsr_t and change
ppc_avr_t to be a simple typedef alias.
Note that due to a difference in the naming of the float32 member between
ppc_avr_t and ppc_vsr_t, references to the ppc_avr_t f member must be replaced
with f32 instead.

The VSX register array is a block of 64 128-bit registers where the first 32
registers consist of the existing 64-bit FP registers extended to 128-bit
using new VSR registers, and the last 32 registers are the VMX 128-bit
registers as show below:
64-bit 64-bit
+--------------------+--------------------+
| FP0 | | VSR0
+--------------------+--------------------+
| FP1 | | VSR1
+--------------------+--------------------+
| ... | ... | ...
+--------------------+--------------------+
| FP30 | | VSR30
+--------------------+--------------------+
| FP31 | | VSR31
+--------------------+--------------------+
| VMX0 | VSR32
+-----------------------------------------+
| VMX1 | VSR33
+-----------------------------------------+
| ... | ...
+-----------------------------------------+
| VMX30 | VSR62
+-----------------------------------------+
| VMX31 | VSR63
+-----------------------------------------+
In order to allow for future conversion of VSX instructions to use TCG vector
operations, recreate the same layout using an aligned version of the existing
vsr register array.
Since the old fpr and avr register arrays are removed, the existing callers
must also be updated to use the correct offset in the vsr register array. This
also includes switching the relevant VMState fields over to using subarrays
to make sure that migration is preserved.

to have prompted Coverity to warn (CID 1396862):
illegal_address: &frame->mc_vregs.altivec[34] evaluates to an address that is
at byte offset 544 of an array of 528 bytes.

...and then CID 1396863 is the same issue for this line.
Is this legit, or a false-positive ?

From: Michael Roth <mdroth@linux.vnet.ibm.com>
This adds cleanup counterparts to pci_register_root_bus(),
pci_root_bus_new(), and pci_bus_irqs().
These cleanup routines are needed in the case of hotpluggable
PCIHostBridge implementations. Currently we can rely on the
object_unparent()'ing of the PCIHostState recursively unparenting
and cleaning up it's child buses, but we need explicit calls
to also:
1) remove the PCIHostState from pci_host_bridges global list.
otherwise, we risk accessing freed memory when we access
the list later
2) clean up memory allocated in pci_bus_irqs()
Both are handled outside the context of any particular bus or
host bridge's init/realize functions, making it difficult to
avoid the need for explicit cleanup functions without remodeling
how PCIHostBridges are created. So keep it simple and just add
them for now.

The qirq routines of the XiveSource and the sPAPRXive model are only
used under the sPAPR IRQ backend. Simplify the overall call stack and
gather all the code under spapr_qirq_xive(). It will ease future
changes.

From: Cédric Le Goater <clg@kaod.org>
Today, the interrupt presenter is linked to a CPU using the
cpu_intc_create() method of the sPAPR IRQ backend. The resulting
object is assigned to the PowerPCCPU 'intc' pointer whatever the
interrupt mode, XICS or XIVE.
To support the 'dual' interrupt mode, we will need to distinguish
between the two presenter objects and for that, we plan to introduce a
second interrupt presenter object pointer under the PowerPCCPU. The
modifications below move the assignment of the presenter object under
the cpu_intc_create() method to prepare ground for the future changes.
Both sPAPR and PowerNV machines are impacted.

The error value can be squashed by the section handling radix migration.
Simply bail out if an error occurs when the RTC offset is imported.
This fixes the Coverity issue CID 1398591.

To support the 'dual' interrupt mode, XICS and XIVE, we plan to move
the qemu_irq array of each interrupt controller under the machine and
do the allocation under the sPAPR IRQ init method.

Future changes of the ICSState object will remove the qemu_irq array
from under the interrupt controller model. Prepare ground for the PSI
interrupt sources and introduce a new one directly under the PSI
device model.

The qemu_irq array is now allocated at the machine level using a sPAPR
IRQ set_irq handler depending on the chosen interrupt mode. The use of
this handler is slightly inefficient today but it will become necessary
when the 'dual' interrupt mode is introduced.

commit 15ed653fa49a ("ppc/xics: An ICS with offset 0 is assumed to be
uninitialized") introduced an extra check on the ICS offset which is
not strictly necessary.
Revert the change to be able to map the XICS IRQ number space on the
XIVE IRQ number space.

From: Cédric Le Goater <clg@kaod.org>
The 'dual' sPAPR IRQ backend supports both interrupt mode, XIVE
exploitation mode and the legacy compatibility mode (XICS). both modes
are not supported at the same time.
The machine starts with the legacy mode and a new interrupt mode can
then be negotiated by the CAS process. In this case, the new mode is
activated after a reset to take into account the required changes in
the machine. These impact the device tree layout, the interrupt
presenter object and the exposed MMIO regions in the case of XIVE.
