The earlier implementation fell into a corner case for bytes that were
0x01, giving a wrong result (but not affecting our application test
cases for strings, as an ASCII value 0x01 is rare in those...).
This changes the algorithm to:
1. Mask out the high-bit of each bytes (so that each byte is <= 127).
2. Add 127 to each byte (i.e. if the low 7 bits are not 0, this will overflow
into the highest bit of each byte).
3. Bitwise-or the original value back in (to cover those cases where the
source byte was exactly 128) to saturate the high-bit.
4. Shift-and-mask (implemented as a mask-and-shift) to extract the MSB of
each byte into its LSB.
5. Multiply with 0xff to fan out the LSB to all bits of each byte.

hw/acpi/aml-build: Add PPTT table
Add the Processor Properties Topology Table (PPTT) used to
describe CPU topology information to ACPI guests.
Note, a DT-boot Linux guest with a non-flat CPU topology will
see socket and core IDs being sequential integers starting
from zero, which is different from ACPI-boot Linux guest,
e.g. with -smp 4,sockets=2,cores=2,threads=1
a DT boot produces:
cpu: 0 package_id: 0 core_id: 0
cpu: 1 package_id: 0 core_id: 1
cpu: 2 package_id: 1 core_id: 0
cpu: 3 package_id: 1 core_id: 1
an ACPI boot produces:
cpu: 0 package_id: 36 core_id: 0
cpu: 1 package_id: 36 core_id: 1
cpu: 2 package_id: 96 core_id: 2
cpu: 3 package_id: 96 core_id: 3
This is due to several reasons:
1) DT cpu nodes do not have an equivalent field to what the PPTT
ACPI Processor ID must be, i.e. something equal to the MADT CPU
UID or equal to the UID of an ACPI processor container. In both
ACPI cases those are platform dependant IDs assigned by the
vendor.
2) While QEMU is the vendor for a guest, if the topology specifies
SMT (> 1 thread), then, with ACPI, it is impossible to assign a
core-id the same value as a package-id, thus it is not possible
to have package-id=0 and core-id=0. This is because package and
core containers must be in the same ACPI namespace and therefore
must have unique UIDs.
3) ACPI processor containers are not mandatorily required for PPTT
tables to be used and, due to the limitations of which IDs are
selected described above in (2), they are not helpful for QEMU,
so we don't build them with this patch. In the absence of them,
Linux assigns its own unique IDs. The maintainers have chosen not
to use counters from zero, but rather ACPI table offsets, which
explains why the numbers are so much larger than with DT.
4) When there is no SMT (threads=1) the core IDs for ACPI boot guests
match the logical CPU IDs, because these IDs must be equal to the
MADT CPU UID (as no processor containers are present), and QEMU
uses the logical CPU ID for these MADT IDs.
So in summary, with QEMU as the vendor for the guests, we simply
use sequential integers starting from zero for the non-leaf nodes
but with ID-valid flag unset, so that guest will ignore them and
use table offsets as unique container IDs. And we use logical CPU
IDs for the leaf nodes with the ID-valid flag set, which will be
consistent with MADT.
Currently the implementation of PPTT generation complies with ACPI
specification 5.2.29 (Revision 6.3). The 6.3 spec can be found at:

hw/arm/virt: Add cpu-map to device tree
Support device tree CPU topology descriptions.
In accordance with the Devicetree Specification, the Linux Doc
"arm/cpus.yaml" requires that cpus and cpu nodes in the DT are
present. And we have already met the requirement by generating
/cpus/cpu@* nodes for members within ms->smp.cpus. Accordingly,
we should also create subnodes in cpu-map for the present cpus,
each of which relates to an unique cpu node.
The Linux Doc "cpu/cpu-topology.txt" states that the hierarchy
of CPUs in a SMP system is defined through four entities and
they are socket/cluster/core/thread. It is also required that
a socket node's child nodes must be one or more cluster nodes.
Given that currently we are only provided with information of
socket/core/thread, we assume there is one cluster child node
in each socket node when creating cpu-map.

hw/arm/virt: Only describe cpu topology since virt-6.2
On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.
Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

hw/ppc/ppc4xx_pci: Fix ppc4xx_pci_map_irq() for recent Linux kernels
Recent Linux kernels are accessing the PCI device in slot 0 that
represents the PCI host bridge. This causes ppc4xx_pci_map_irq()
to return -1 which causes an assert() later:
hw/pci/pci.c:262: pci_bus_change_irq_level: Assertion `irq_num >= 0' failed.
Thus we should allocate an IRQ line for the device in slot 0, too.
To avoid changes to the outside of ppc4xx_pci.c, we map it to
the internal IRQ number 4 which will then happily be ignored since
ppc440_bamboo.c does not wire it up.
With these changes it is now possible again to use recent Linux
kernels for the bamboo board.

target/ppc: add user read/write functions for MMCR0
Userspace need access to PMU SPRs to be able to operate the PMU. One of
such SPRs is MMCR0.
MMCR0, as defined by PowerISA v3.1, is classified as a 'group A' PMU
register. This class of registers has common read/write rules that are
governed by MMCR0 PMCC bits. MMCR0 is also not fully exposed to problem
state: only MMCR0_FC, MMCR0_PMAO and MMCR0_PMAE bits are
readable/writable in this case.
This patch exposes MMCR0 to userspace by doing the following:
- two new callbacks, spr_read_MMCR0_ureg() and spr_write_MMCR0_ureg(),
are added to be used as problem state read/write callbacks of UMMCR0.
Both callbacks filters the amount of bits userspace is able to
read/write by using a MMCR0_UREG_MASK;
- problem state access control is done by the spr_groupA_read_allowed()
and spr_groupA_write_allowed() helpers. These helpers will read the
current PMCC bits from DisasContext and check whether the read/write
MMCR0 operation is valid or noti;
- to avoid putting exclusive PMU logic into the already loaded
translate.c file, let's create a new 'power8-pmu-regs.c.inc' file that
will hold all the spr_read/spr_write functions of PMU registers.
The 'power8' name of this new file intends to hint about the proven
support of the PMU logic to be added. The code has been tested with the
IBM POWER chip family, POWER8 being the oldest version tested. This
doesn't mean that the PMU logic will break with any other PPC64 chip
that implements Book3s, but rather that we can't assert that it works
properly with any Book3s compliant chip.

target/ppc: add MMCR0 PMCC bits to hflags
We're going to add PMU support for TCG PPC64 chips, based on IBM POWER8+

access of the PMU registers to problem state.

roms/edk2: Only initialize required submodules
The EDK2 firmware images built to test QEMU do not require
the following submodules:
- MdeModulePkg/Universal/RegularExpressionDxe/oniguruma
- UnitTestFrameworkPkg/Library/CmockaLib/cmocka
The only submodules required are:

hw/arm/virt: Don't create device-tree node for empty NUMA node
The empty NUMA node, where no memory resides, are allowed. For
example, the following command line specifies two empty NUMA nodes.
With this, QEMU fails to boot because of the conflicting device-tree
node names, as the following error message indicates.
/home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \

:
qemu-system-aarch64: FDT: Failed to create subnode /memory@
80000000: FDT_ERR_EXISTS
As specified by linux device-tree binding document, the device-tree
nodes for these empty NUMA nodes shouldn't be generated. However,
the corresponding NUMA node IDs should be included in the distance
map. The memory hotplug through device-tree on ARM64 isn't existing
so far and it's not necessary to require the user to provide a distance
map. Furthermore, the default distance map Linux generates may even be
sufficient. So this simply skips populating the device-tree nodes for
these empty NUMA nodes to avoid the error, so that QEMU can be started
successfully.

tests/acpi/bios-tables-test: update DSDT blob for multifunction bridge test
We added a new unit test for testing acpi hotplug on multifunction bridges in
q35 machines. Here, we update the DSDT table gloden master blob for this unit
test.
The test adds the following devices to qemu and then checks the changes
introduced in the DSDT table due to the addition of the following devices:
(a) a multifunction bridge device
(b) a bridge device with function 1
(c) a non-bridge device with function 2
In the DSDT table, we should see AML hotplug descriptions for (a) and (b).
For (a) we should find a hotplug AML description for function 0.
Following is the ASL diff between the original DSDT table and the modified DSDT
table due to the unit test. We see that multifunction bridge on bus 2 and single
function bridge on bus 3 function 1 are described, not the non-bridge balloon
device on bus 4, function 2.

tests/acpi/pcihp: add unit tests for hotplug on multifunction bridges for q35
commit
d7346e614f4ec ("acpi: x86: pcihp: add support hotplug on multifunction bridges")
added ACPI hotplug descriptions for cold plugged bridges for functions other
than 0. For all other devices, the ACPI hotplug descriptions are limited to
function 0 only. This change adds unit tests for this feature.
This test adds the following devices to qemu and then checks the changes
introduced in the DSDT table due to the addition of the following devices:
(a) a multifunction bridge device
(b) a bridge device with function 1
(c) a non-bridge device with function 2
In the DSDT table, we should see AML hotplug descriptions for (a) and (b).
For (a) we should find a hotplug AML description for function 0.
The following diff compares the DSDT table AML with the new unit test before
and after the change
d7346e614f4ec is introduced. In other words,
this diff reflects the changes that occurs in the DSDT table due to the change
d7346e614f4ec .
