object_get_canonical_path_component() returns a malloced copy of a
property name on success, null on failure.
19 of its 25 callers immediately free the returned copy.
Change object_get_canonical_path_component() to return the property
name directly. Since modifying the name would be wrong, adjust the

In armsse_realize() we have a loop over [0, info->num_cpus), which
indexes into various fixed-size arrays in the ARMSSE struct. This
confuses Coverity, which warns that we might overrun those arrays
(CID 1430326, 1430337, 1430371, 1430414, 1430430). This can't
actually happen, because the info struct is always one of the entries
in the armsse_variants[] array and num_cpus is either 1 or 2; we also
already assert in armsse_init() that num_cpus is not too large.
However, adding an assert to armsse_realize() like the one in
armsse_init() should help Coverity figure out that these code paths
aren't possible.

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {

out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),

it helps here.
The match of return is narrower than what I want, but I can't figure

The FROM_SSI_SLAVE() macro predates QOM and is used as a typesafe way
to cast from an SSISlave* to the instance struct of a subtype of
TYPE_SSI_SLAVE. Switch to using the QOM cast macros instead, which
have the same effect (by writing the QOM macros if the types were
previously missing them.)
(The FROM_SSI_SLAVE() macro allows the SSISlave member of the
subtype's struct to be anywhere as long as it is named "ssidev",
whereas a QOM cast macro insists that it is the first thing in the
subtype's struct. This is true for all the types we convert here.)

Using GPIO lines will make it easier for board code to wire things

its output GPIO, which is then wired up by the board to the

create a proper abstract class SpitzMachineClass which encapsulates
the common behaviour, rather than having them all derive directly
from TYPE_MACHINE:
* instead of each machine class setting mc->init to a wrapper
function which calls spitz_common_init() with parameters,
put that data in the SpitzMachineClass and make spitz_common_init
the SpitzMachineClass machine-init function
* move the settings of mc->block_default_type and
mc->ignore_memory_transaction_failures into the SpitzMachineClass
class init rather than repeating them in each machine's class init
(The motivation is that we're going to want to keep some state in
the SpitzMachineState so we can connect GPIOs between devices created
in one sub-function of the machine init to devices created in a
different sub-function.)

The flash device is exclusively for the host-controlled firmware, so
we should not expose it to the OS. Exposing it risks the OS messing
with it, which could break firmware runtime services and surprise the
OS when all its changes disappear after reboot.
As firmware needs the device and uses DT, we leave the device exposed
there. It's up to firmware to remove the nodes from DT before sending
it on to the OS. However, there's no need to force firmware to remove
tables from ACPI (which it doesn't know how to do anyway), so we
simply don't add the tables in the first place. But, as we've been
adding the tables for quite some time and don't want to change the
default hardware exposed to versioned machines, then we only stop
exposing the flash device tables for 5.1 and later machine types.

At the moment the virtio-iommu translates MSI transactions.
This behavior is inherited from ARM SMMU. The virt machine
code knows where the guest MSI doorbells are so we can easily
declare those regions as VIRTIO_IOMMU_RESV_MEM_T_MSI. With that
setting the guest will not map MSIs through the IOMMU and those
transactions will be simply bypassed.
Depending on which MSI controller is in use (ITS or GICV2M),
we declare either:
- the ITS interrupt translation space (ITS_base + 0x10000),
containing the GITS_TRANSLATOR or
- The GICV2M single frame, containing the MSI_SETSP_NS register.

Let's auto-enable it also when maxmem is specified but no slots are
defined. This will result in us properly creating ACPI srat tables,
indicating the maximum possible PFN to the guest OS. Based on this, e.g.,
Linux will enable the swiotlb properly.
This avoids having to manually force the switolb on (swiotlb=force) in
Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64),
and virtio-mem adds memory later on that really needs the swiotlb to be
used for DMA.
Let's take care of backwards compatibility if somebody has a setup that
specifies "maxram" without "slots".

I'm confused by this code, 'bmc' is created as:
bmc = g_new0(AspeedBoardState, 1);
Then we use it as QOM owner for different MemoryRegion objects.
But looking at memory_region_init_ram (similarly for ROM):
void memory_region_init_ram(MemoryRegion *mr,
struct Object *owner,
const char *name,
uint64_t size,
Error **errp)
{
DeviceState *owner_dev;
Error *err = NULL;
memory_region_init_ram_nomigrate(mr, owner, name, size, &err);
if (err) {
error_propagate(errp, err);
return;
}
/* This will assert if owner is neither NULL nor a DeviceState.
* We only want the owner here for the purposes of defining a
* unique name for migration. TODO: Ideally we should implement
* a naming scheme for Objects which are not DeviceStates, in
* which case we can relax this restriction.
*/
owner_dev = DEVICE(owner);
vmstate_register_ram(mr, owner_dev);
}
The expected assertion is not triggered ('bmc' is not NULL neither
a DeviceState).
'bmc' structure is defined as:
struct AspeedBoardState {
AspeedSoCState soc;
MemoryRegion ram_container;
MemoryRegion max_ram;
};
What happens is when using 'OBJECT(bmc)', the QOM macros cast the
memory pointed by bmc, which first member is 'soc', which is
initialized ...:
object_initialize_child(OBJECT(machine), "soc",
&bmc->soc, amc->soc_name);
The 'soc' object is indeed a DeviceState, so the assertion passes.
Since this is fragile and only happens to work by luck, remove the
dangerous OBJECT(bmc) owner argument.
Note, this probably breaks migration for this machine.

This script is *unsound*: we need to manually verify init and realize
conversions are properly paired.
This commit has only the pairs where object_initialize_child()'s
@child and sysbus_realize()'s @dev argument text match exactly within
the same source file.
Note that Coccinelle chokes on ARMSSE typedef vs. macro in
hw/arm/armsse.c. Worked around by temporarily renaming the macro for
the spatch run.

The number of MACs supported by an Aspeed SoC is defined by "macs_num"
under the SoC model, that is two for the AST2400 and AST2500 and four
for the AST2600. The model initializes the maximum number of supported
MACs but the number of realized devices is capped by the number of
network device back-ends defined on the command line. This can leave
unrealized devices hanging around in the QOM composition tree.
To get virtual hardware that matches the physical hardware, you have
to pass exactly as many -nic options as there are MACs, and some of
them must be -nic none:
* Machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc,
swift-bmc, and witherspoon-bmc: two -nic, and the second one must be
-nic none.
* Machine ast2600-evb: four -nic, the first one must be -nic none.
* Machine tacoma-bmc: four nic, the first two and the last one must be
-nic none.
Modify the machine initialization to define which MACs are attached to
a network device back-end using a bit-field property "macs-mask" and
let the SoC realize all network devices.
The default setting of "macs-mask" is "use MAC0" only, which works for
all our AST2400 and AST2500 machines. The AST2600 machines have
different configurations. The AST2600 EVB machine activates MAC1, MAC2
and MAC3 and the Tacoma BMC machine activates MAC2.
Incompatible CLI change: -nic options now apply to *active* MACs:
MAC1, MAC2, MAC3 for ast2600-evb, MAC2 for tacoma-bmc, and MAC0 for
all the others.

Commit ece09beec4 ("aspeed: introduce a configurable number of CPU
per machine") was a convient change during bringup but the Aspeed SoCs
have a fixed number of CPUs : one for the AST2400 and AST2500, and two
for the AST2600.
When the number of CPUs configured with -smp is less than the SoC's
fixed number, the "unconfigured" CPUs are left unrealized. This can
happen for machines ast2600-evb and tacoma-bmc, where the SoC's fixed
number is 2. To get virtual hardware that matches the physical
hardware, you have to pass -smp cpus=2 (or its sugared form -smp 2).
We normally reject -smp cpus=N when N exceeds the machine's limit.
Except we ignore cpus=2 (and only cpus=2) with a warning for machines
ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and
witherspoon-bmc.
Remove the "num-cpu" property from the SoC state and use the fixed
number of CPUs defined in the SoC class instead. Compute the default,
min, max number of CPUs of the machine directly from the SoC class
definition.

stm32f405_soc_initfn() creates six such devices, but
stm32f405_soc_realize() realizes only one. Affects machine
netduinoplus2.
In theory, a device becomes real only on realize. In practice, the
transition from unreal to real is a fuzzy one. The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize). Depending on
what exactly is done where, a device can work even when we neglect
to realize it.
The five unrealized devices appear to stay unreal: neither MMIO nor
IRQ get wired up.

memory_region_set_size() handle the 16 Exabytes limit by
special-casing the UINT64_MAX value. This is not a problem
for the 32-bit maximum, 4 GiB.
By using the UINT32_MAX value, the aspeed-ram-container
MemoryRegion ends up missing 1 byte:
$ qemu-system-arm -M ast2600-evb -S -monitor stdio
(qemu) info mtree

NVDIMMs can belong to their own proximity domains, as described by the
NFIT. In such cases, the SRAT needs to have Memory Affinity structures
in the SRAT for these NVDIMMs, otherwise Linux doesn't populate node
data structures properly during NUMA initialization. See the following
for an example failure case.
https://lore.kernel.org/linux-nvdimm/20200416225438.15208-1-vishal.l.verma@intel.com/
Introduce a new helper, nvdimm_build_srat(), and call it for both the
i386 and arm versions of 'build_srat()' to augment the SRAT with
memory affinity information for NVDIMMs.
The relevant command line options to exercise this are below. Nodes 0-1
contain CPUs and regular memory, and nodes 2-3 are the NVDIMM address
space.

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

object_property_set_description() and
object_class_property_set_description() fail only when property @name
is not found.
There are 85 calls of object_property_set_description() and
object_class_property_set_description(). None of them can fail:
* 84 immediately follow the creation of the property.
* The one in spapr_rng_instance_init() refers to a property created in
spapr_rng_class_init(), from spapr_rng_properties[].
Every one of them still gets to decide what to pass for @errp.
51 calls pass &error_abort, 32 calls pass NULL, one receives the error
and propagates it to &error_abort, and one propagates it to
&error_fatal. I'm actually surprised none of them violates the Error
API.
What are we gaining by letting callers handle the "property not found"
error? Use when the property is not known to exist is simpler: you
don't have to guard the call with a check. We haven't found such a
use in 5+ years. Until we do, let's make life a bit simpler and drop
the @errp parameter.

This is a boot stub that is similar to the code u-boot runs, allowing
the kernel to boot the secondary CPU.
u-boot works as follows:
1. Initialises the SMP mailbox area in the SCU at 0x1e6e2180 with default values
2. Copies a stub named 'mailbox_insn' from flash to the SCU, just above the
mailbox area
3. Sets AST_SMP_MBOX_FIELD_READY to a magic value to indicate the
secondary can begin execution from the stub
4. The stub waits until the AST_SMP_MBOX_FIELD_GOSIGN register is set to
a magic value
5. Jumps to the address in AST_SMP_MBOX_FIELD_ENTRY, starting Linux
Linux indicates it is ready by writing the address of its entrypoint
function to AST_SMP_MBOX_FIELD_ENTRY and the 'go' magic number to
AST_SMP_MBOX_FIELD_GOSIGN. The secondary CPU sees this at step 4 and
breaks out of it's loop.
To be compatible, a fixed qemu stub is loaded into the mailbox area. As
qemu can ensure the stub is loaded before execution starts, we do not
need to emulate the AST_SMP_MBOX_FIELD_READY behaviour of u-boot. The
secondary CPU's program counter points to the beginning of the stub,
allowing qemu to start secondaries at step four.
Reboot behaviour is preserved by resetting AST_SMP_MBOX_FIELD_GOSIGN
when the secondaries are reset.
This is only configured when the system is booted with -kernel and qemu
does not execute u-boot first.
