DIAGNOSE 0x318 (diag318) is an s390 instruction that allows the storage
of diagnostic information that is collected by the firmware in the case
of hardware/firmware service events.
QEMU handles the instruction by storing the info in the CPU state. A
subsequent register sync will communicate the data to the hypervisor.
QEMU handles the migration via a VM State Description.
This feature depends on the Extended-Length SCCB (els) feature. If
els is not present, then a warning will be printed and the SCLP bit
that allows the Linux kernel to execute the instruction will not be
set.
Availability of this instruction is determined by byte 134 (aka fac134)
bit 0 of the SCLP Read Info block. This coincidentally expands into the
space used for CPU entries, which means VMs running with the diag318
capability may not be able to read information regarding all CPUs
unless the guest kernel supports an extended-length SCCB.
This feature is not supported in protected virtualization mode.

As more features and facilities are added to the Read SCP Info (RSCPI)
response, more space is required to store them. The space used to store
these new features intrudes on the space originally used to store CPU
entries. This means as more features and facilities are added to the
RSCPI response, less space can be used to store CPU entries.
With the Extended-Length SCCB (ELS) facility, a KVM guest can execute
the RSCPI command and determine if the SCCB is large enough to store a
complete reponse. If it is not large enough, then the required length
will be set in the SCCB header.
The caller of the SCLP command is responsible for creating a
large-enough SCCB to store a complete response. Proper checking should
be in place, and the caller should execute the command once-more with
the large-enough SCCB.
This facility also enables an extended SCCB for the Read CPU Info
(RCPUI) command.
When this facility is enabled, the boundary violation response cannot
be a result from the RSCPI, RSCPI Forced, or RCPUI commands.
In order to tolerate kernels that do not yet have full support for this
feature, a "fixed" offset to the start of the CPU Entries within the
Read SCP Info struct is set to allow for the original 248 max entries
when this feature is disabled.
Additionally, this is introduced as a CPU feature to protect the guest
from migrating to a machine that does not support storing an extended
SCCB. This could otherwise hinder the VM from being able to read all
available CPU entries after migration (such as during re-ipl).

The header contained within the SCCB passed to the SCLP service call
contains the actual length of the SCCB. Instead of allocating a static
4K size for the work sccb, let's allow for a variable size determined
by the value in the header. The proper checks are already in place to
ensure the SCCB length is sufficent to store a full response and that
the length does not cross any explicitly-set boundaries.

My memory isn't good enough to memorize what these magic runes

Side note: I assume it's safe to always set 0xA0 even though ATA2 claims
these bits are reserved, because ATA3 immediately reinstated that these
bits should be always on. ATA4 and subsequent specs only claim that the
fields are obsolete, so I assume it's safe to leave these set and that
it should work with the widest array of guests.

I have been staring at this FIXME for years and I never knew what it
meant. I finally stumbled across it!
When writing to the command registers, the old value is shifted into a
HOB copy of the register and the new value is written into the primary
register. When reading registers, the value retrieved is dependent on
the HOB bit in the CONTROL register.
By setting bit 7 (0x80) in CONTROL, any register read will, if it has
one, yield the HOB value for that register instead.
Our code has a problem: We were using bit 7 of the DEVICE register to
model this. We use bus->cmd roughly as the control register already, as
it stores the value from ide_ctrl_write.
Lastly, all command register writes reset the HOB, so fix that, too.

QEMU's kvmclock device is only created when KVM PV feature bits for
kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are
exposed to the guest. With 'kvm=off' cpu flag the device is not
created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration.
It was reported that without these call at least Hyper-V TSC page
clocksouce (which can be enabled independently) gets broken after
migration.
Switch to creating kvmclock QEMU device unconditionally, it seems
to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration.

before sending next VHOST-USER command, then the vhost_dev_set_log()
call in the vhost_migration_log() function will return error. This error
will lead to the assert() and close the QEMU migration source process.
For the vhost-user devices the disconnect event should not break the

- the device will be in the stopped state, so it will not be changed
during migration
- if reconnect will be made the migration log will be reinitialized as

will be used for initialization (vhost_user_blk_start) and clean up
(vhost_user_blk_stop). This additional flag in the VhostUserBlk structure
will be used to track whether the device really needs to be stopped and
cleaned up on a vhost-user level.
The disconnect event will set the overall VHOST device (not vhost-user) to
the stopped state, so it can be used by the general vhost_migration_log
routine.
Such approach could be propogated to the other vhost-user devices, but
better idea is just to make the same connect/disconnect code for all the
vhost-user devices.
This migration issue was slightly discussed earlier:

To speed up the memory mapping updating between vhost-vDPA and vDPA
device driver, this patch passes the IOTLB batching flags via IOTLB
API. Two new flags was introduced, VHOST_IOTLB_BATCH_BEGIN is a hint
that a bathced IOTLB updating may be initiated from the
userspace. VHOST_IOTLB_BATCH_END is a hint that userspace has finished
the updating:
VHOST_IOTLB_BATCH_BEGIN
VHOST_IOTLB_UPDATE/VHOST_IOTLB_INVALIDATE
...
VHOST_IOTLB_BATCH_END
Vhost-vDPA can then know that all mappings has been set and can do
optimization like passing all the mappings to the vDPA device driver.

This patch tries to switch to use new kernel IOTLB format V2. Previous
version may have inconsistent ABI between 32bit and 64bit machines
because of the hole after type field. Refer kernel commit
("429711aec282 vhost: switch to use new message format") for more
information.
To enable this feature, qemu need to use a new ioctl
VHOST_SET_BACKEND_FEATURE with VHOST_BACKEND_F_IOTLB_MSG_V2 bit. A new
vhost setting backend features ops was introduced. And when we try to
set features for vhost dev, we will examine the support of new IOTLB
format and enable it. This process is total transparent to guest,
which means we can have different IOTLB message type in src and dst
during migration.
The conversion of IOTLB message is straightforward, just check the
type and behave accordingly.

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:

sort -u >/tmp/changed_identifiers
$ for identifier in $(</tmp/changed_identifiers); do

Fuzzing discovered that virtqueue_unmap_sg() is being called on modified
req->in/out_sg iovecs. This means dma_memory_map() and
dma_memory_unmap() calls do not have matching memory addresses.

^^^^^^^^^^^^^^^^^^^^^^^
A modified iov->iov_base is no longer recognized as a bounce buffer and
the wrong branch is taken.
There are more potential bugs: dirty memory is not tracked correctly and
MemoryRegion refcounts can be leaked.
Use the new iov_discard_undo() API to restore elem->in/out_sg before
virtqueue_push() is called.

When booting directly into a kernel, bypassing the boot loader, the CPU and
UART clocks are not set up correctly. This makes the system appear very
slow, and causes the initrd boot test to fail when optimization is off.
The UART clock must run at 24 MHz. The default 25 MHz reference clock
cannot achieve this, so switch to PLL2/2 @ 480 MHz, which works
perfectly with the default /20 divider.
The CPU clock should run at 800 MHz, so switch it to PLL1/2. PLL1 runs
at 800 MHz by default, so we need to double the feedback divider as well
to make it run at 1600 MHz (so PLL1/2 runs at 800 MHz).
We don't bother checking for PLL lock because we know our emulated PLLs
lock instantly.

- npcm750-evb: Nuvoton NPCM750 Evaluation Board.
- quanta-gsj: A board with a NPCM730 chip.
They rely on the NPCM7xx SoC device to do the heavy lifting. They are
almost completely identical at the moment, apart from the SoC type,
which currently only changes the reset contents of one register
(GCR.MDLR), but they might grow apart a bit more as more functionality
is added.
Both machines can boot the Linux kernel into /bin/sh.

Management Controllers in servers. While the family includes four SoCs,
this patch implements limited support for two of them: NPCM730 (targeted
for Data Center applications) and NPCM750 (targeted for Enterprise
applications).
This patch includes little more than the bare minimum needed to boot a
Linux kernel built with NPCM7xx support in direct-kernel mode:
- Two Cortex-A9 CPU cores with built-in periperhals.
- Global Configuration Registers.
- Clock Management.
- 3 Timer Modules with 5 timers each.
- 4 serial ports.
The chips themselves have a lot more features, some of which will be
added to the model at a later stage.

The NPCM730 and NPCM750 SoCs have three timer modules each holding five
timers and some shared registers (e.g. interrupt status).
Each timer runs at 25 MHz divided by a prescaler, and counts down from a
configurable initial value to zero. When zero is reached, the interrupt
flag for the timer is set, and the timer is disabled (one-shot mode) or
reloaded from its initial value (periodic mode).
This implementation is sufficient to boot a Linux kernel configured for
NPCM750. Note that the kernel does not seem to actually turn on the
interrupts.

Microchip PolarFire SoC integrates one Cadence SDHCI controller.
On the Icicle Kit board, one eMMC chip and an external SD card
connect to this controller depending on different configuration.
As QEMU does not support eMMC yet, we just emulate the SD card
configuration. To test this, the Hart Software Services (HSS)
should choose the SD card configuration:
$ cp boards/icicle-kit-es/def_config.sdcard .config
$ make BOARD=icicle-kit-es
The SD card image can be built from the Yocto BSP at:
https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp
Note the generated SD card image should be resized before use:
$ qemu-img resize /path/to/sdcard.img 4G
Launch QEMU with the following command:
$ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img

Vcpus have an additional paramenter to be appended, vcpu_id. This
also changes the size of the of property itself, which is being
represented in index 0 of numa_assoc_array[cpu->node_id],
and defaults to MAX_DISTANCE_REF_POINTS for all cases but
vcpus.
All this logic makes more sense in spapr_numa.c, where we handle

Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
The next step to centralize all NUMA/associativity handling in
the spapr machine is to create a 'one stop place' for all
things ibm,associativity.
This patch introduces numa_assoc_array, a 2 dimensional array
that will store all ibm,associativity arrays of all NUMA nodes.
This array is initialized in a new spapr_numa_associativity_init()
function, called in spapr_machine_init(). It is being initialized
with the same values used in other ibm,associativity properties
around spapr files (i.e. all zeros, last value is node_id).
The idea is to remove all hardcoded definitions and FDT writes
of ibm,associativity arrays, doing instead a call to the new
helper spapr_numa_write_associativity_dt() helper, that will
be able to write the DT with the correct values.
We'll start small, handling the trivial cases first. The
remaining instances of ibm,associativity will be handled
next.

We're going to make changes in how spapr handles all
ibm,associativity* related properties to enhance our current NUMA
support.
At this moment we have associativity code scattered all around
spapr_* files, with hardcoded values and array sizes. This
makes it harder to change any NUMA specific parameters in
the future. Having everything in the same place allows not
only for easier tuning, but also easier understanding since all
NUMA related code is on the same file.
This patch introduces a new file to gather all NUMA/associativity
handling code in spapr, spapr_numa.c. To get things started, let's
remove associativity-reference-points and max-associativity-domains
code from spapr_dt_rtas() to a new helper called spapr_numa_write_rtas_dt().
This will decouple spapr_dt_rtas() from the NUMA changes that
are going to happen in those two properties.

generalize the start-powered-off property so that it can be used by them.
Note that ARMv7MState also has a property of the same name but this patch
doesn't change it because that class isn't a subclass of CPUState so it
wouldn't be a trivial change.
This change should not cause any change in behavior.

spapr_nvdimm_validate() to reflect that the function is now checking

and KVM will configure the escalation priority to a lower number. In
any case, the guest is allowed to use priorities in a single range :
[ 0 .. (maxprio - 1) ].
Introduce a 'hv-prio' property to represent the escalation priority

This allows qemu to run the "normal" power on reset boot path through
u-boot, where the DDR is trained.
An enhancement would be to have the SCU bit stick across qemu reboots,
but be unset on initial boot.
Proper modelling would be to discard all writes to the phy setting regs
at offset 0x100 - 0x400 and to model the phy status regs at offset
0x400.
The status regs model would only need to account for offets 0x00,
0x50, 0x68 and 0x7c.

TYPE_ARM_SSE is a TYPE_SYS_BUS_DEVICE subclass, but
ARMSSEClass::parent_class is declared as DeviceClass.
It never caused any problems by pure luck:
We were not setting class_size for TYPE_ARM_SSE, so class_size of
TYPE_SYS_BUS_DEVICE was being used (sizeof(SysBusDeviceClass)).
This made the system allocate enough memory for TYPE_ARM_SSE
devices even though ARMSSEClass was too small for a sysbus
device.
Additionally, the ARMSSEClass::info field ended up at the same
offset as SysBusDeviceClass::explicit_ofw_unit_address. This
would make sysbus_get_fw_dev_path() crash for the device.
Luckily, sysbus_get_fw_dev_path() never gets called for
TYPE_ARM_SSE devices, because qdev_get_fw_dev_path() is only used
by the boot device code, and TYPE_ARM_SSE devices don't appear at
the fw_boot_order list.

Clock canonical name is set in device_set_realized (see the block
added to hw/core/qdev.c in commit 0e6934f264).
If we connect a clock after the device is realized, this code is
not executed. This is currently not a problem as this name is only
used for trace events, however this disrupt tracing.
Add a comment to document qdev_connect_clock_in() must be called
before the device is realized, and assert this condition.
