The System Management Bus is more or less a derivative of the I2C
bus, thus the Kconfig entry depends of I2C.
Not all boards providing an I2C bus support SMBus.
Use two different Kconfig entries to be able to select I2C without
selecting SMBus.

QEMU allows to create SD card with unrealistic sizes. This could
work, but some guests (at least Linux) consider sizes that are not
a power of 2 as a firmware bug and fix the card size to the next
power of 2.
While the possibility to use small SD card images has been seen as
a feature, it became a bug with CVE-2020-13253, where the guest is
able to do OOB read/write accesses past the image size end.
In a pair of commits we will fix CVE-2020-13253 as:
Read command is rejected if BLOCK_LEN_ERROR or ADDRESS_ERROR
occurred and no data transfer is performed.
Write command is rejected if BLOCK_LEN_ERROR or ADDRESS_ERROR
occurred and no data transfer is performed.
WP_VIOLATION errors are not modified: the error bit is set, we
stay in receive-data state, wait for a stop command. All further
data transfer is ignored. See the check on sd->card_status at the
beginning of sd_read_data() and sd_write_data().
While this is the correct behavior, in case QEMU create smaller SD
cards, guests still try to access past the image size end, and QEMU
considers this is an invalid address, thus "all further data transfer
is ignored". This is wrong and make the guest looping until
eventually timeouts.
Fix by not allowing invalid SD card sizes (suggesting the expected
size as a hint):
$ qemu-system-arm -M orangepi-pc -drive file=rootfs.ext2,if=sd,format=raw
qemu-system-arm: Invalid SD card size: 60 MiB
SD card size has to be a power of 2, e.g. 64 MiB.
You can resize disk images with 'qemu-img resize <imagefile> <new-size>'
(note that this will lose data if you make the image smaller than it currently is).

OpenSBI is the default firmware in Qemu and has various firmware loading
options. Currently, qemu loader uses fw_jump which has a compile time
pre-defined address where fdt & kernel image must reside. This puts a
constraint on image size of the Linux kernel depending on the fdt location
and available memory. However, fw_dynamic allows the loader to specify
the next stage location (i.e. Linux kernel/U-Boot) in memory and other
configurable boot options available in OpenSBI.
Add support for OpenSBI dynamic firmware loading support. This doesn't
break existing setup and fw_jump will continue to work as it is. Any
other firmware will continue to work without any issues as long as it
doesn't expect anything specific from loader in "a2" register.

Currently, the fdt is copied to the ROM after the reset vector. The firmware
has to copy it to DRAM. Instead of this, directly copy the device tree to a
pre-computed dram address. The device tree load address should be as far as
possible from kernel and initrd images. That's why it is kept at the end of
the DRAM or 4GB whichever is lesser.

This reverts commit 8d5a24c83d.
Compiling all virtio-gpu objects into a single module isn't a good plan
because the individual objects have different CONFIG_* dependencies.
Leads to module load failures on s390x due to vga support being
disabled, which in turn breaks '-device virtio-gpu-device' (flagged by
travis ci).
So back to the drawing board for modular virtio-gpu ...

The MachineClass uses an inverted logic (inherited from the
PC machines [*]) to create the chardev backends for the default
devices (see commits 998bbd74b9d..aa40fc9c964 and ac33f8fad1).
As the none-machine doesn't have any hardware device, it is
pointless to initialize chardev backends. Fix by setting the
'no_defaults' bits in its MachineClass.

If we want to check error after errp-function call, we need to
introduce local_err and then propagate it to errp. Instead, use
the ERRP_GUARD() macro, benefits are:
1. No need of explicit error_propagate call
2. No need of explicit local_err variable: use errp directly
3. ERRP_GUARD() leaves errp as is if it's not NULL or
&error_fatal, this means that we don't break error_abort
(we'll abort on error_set, not on error_propagate)
If we want to add some info to errp (by error_prepend() or
error_append_hint()), we must use the ERRP_GUARD() macro.
Otherwise, this info will not be added when errp == &error_fatal
(the program will exit prior to the error_append_hint() or
error_prepend() call). No such cases are being fixed here.

Otherwise, this info will not be added when errp == &error_fatal
(the program will exit prior to the error_append_hint() or
error_prepend() call). No such cases are being fixed here.

When migrate_add_blocker(blocker, &errp) is followed by
error_propagate(errp, err), we can often just as well do
migrate_add_blocker(..., errp).
Do that with this Coccinelle script:
@@
expression blocker, err, errp;
expression ret;
@@
- ret = migrate_add_blocker(blocker, &err);
- if (err) {
+ ret = migrate_add_blocker(blocker, errp);

Double-check @err is not used afterwards. Dereferencing it would be
use after free, but checking whether it's null would be legitimate.

When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away. The previous commit did that with a Coccinelle script I
consider fairly trustworthy. This commit uses the same script with
the matching of return taken out, i.e. we convert
if (!foo(..., &err)) {
...
error_propagate(errp, err);
...
}
to
if (!foo(..., errp)) {
...
...
}
This is unsound: @err could still be read between afterwards. I don't
know how to express "no read of @err without an intervening write" in
Coccinelle. Instead, I manually double-checked for uses of @err.
Suboptimal line breaks tweaked manually. qdev_realize() simplified
further to placate scripts/checkpatch.pl.

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there. Converted manually.
Line breaks tidied up manually. One nested declaration of @local_err
deleted manually. Preexisting unwanted blank line dropped in

Replace
error_setg(&err, ...);
error_propagate(errp, err);
by
error_setg(errp, ...);
Related pattern:
if (...) {
error_setg(&err, ...);
goto out;
}
...
out:
error_propagate(errp, err);
return;
When all paths to label out are that way, replace by
if (...) {
error_setg(errp, ...);
return;
}
and delete the label along with the error_propagate().
When we have at most one other path that actually needs to propagate,
and maybe one at the end that where propagation is unnecessary, e.g.
foo(..., &err);
if (err) {
goto out;
}
...
bar(..., &err);
out:
error_propagate(errp, err);
return;
move the error_propagate() to where it's needed, like
if (...) {
foo(..., &err);
error_propagate(errp, err);
return;
}
...
bar(..., errp);
return;
and transform the error_setg() as above.
In some places, the transformation results in obviously unnecessary
error_propagate(). The next few commits will eliminate them.
Bonus: the elimination of gotos will make later patches in this series
easier to review.

Add deprecation message to the audio init function.
Factor out audio initialization and call that from
both audio init and realize, so setting the audiodev
property is enough to properly initialize pcspk.
Add a property alias to the machine type to set the
audio device, so pcspk can be initialized using:
"-machine pcspk-audiodev=<name>"
Using "-global isa-pcspk.audiodev=<name>" works too but

hw_error() dumps the CPU state and exits QEMU. This is ok during initial
code development (to see where the guest code is currently executing),
but it is certainly not the desired behavior that we want to present to
normal users, and it can also cause trouble when e.g. fuzzing devices.
Thus let's replace these hw_error()s by qemu_log_mask()s instead.

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.)
This removes all the uses of FROM_SSI_SLAVE() so we can delete the
definition.

Currently we have a free-floating set of IRQs and a function
spitz_out_switch() which handle some miscellaneous GPIO lines for the
spitz board. Encapsulate this behaviour in a simple QOM device.
At this point we can finally remove the 'max1111' global, because the
ADC battery-temperature value is now handled by the misc-gpio device
writing the value to its outbound "adc-temp" GPIO, which the board
code wires up to the appropriate inbound GPIO line on the max1111.
This commit also fixes Coverity issue CID 1421913 (which pointed out
that the 'outsignals' in spitz_scoop_gpio_setup() were leaked),
because it removes the use of the qemu_allocate_irqs() API from this
code entirely.

The max111x ADC device model allows other code to set the level on
the 8 ADC inputs using the max111x_set_input() function. Replace
this with generic qdev GPIO inputs, which also allow inputs to be set

Using GPIO lines will make it easier for board code to wire things
up, so that if device A wants to set the ADC input it doesn't need to
have a direct pointer to the max111x but can just set that value on
its output GPIO, which is then wired up by the board to the

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.

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.

The machine may need to pass reserved regions to the
virtio-iommu-pci device (such as the MSI window on x86
or the MSI doorbells on ARM).
So let's add an array of Interval properties.
Note: if some reserved regions are already set by the
machine code - which should be the case in general -,
the length of the property array is already set and
prevents the end-user from modifying them. For example,
attempting to use:
-device virtio-iommu-pci,\
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1
would result in the following error message:
qemu-system-aarch64: -device virtio-iommu-pci,addr=0xa,
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1:
array size property len-reserved-regions may not be set more than once
Otherwise, for example, adding two reserved regions is achieved
using the following options:
-device virtio-iommu-pci,addr=0xa,len-reserved-regions=2,\
reserved-regions[0]=0xfee00000:0xfeefffff:1,\
reserved-regions[1]=0x1000000:100ffff:1

When translating an address we need to check if it belongs to
a reserved virtual address range. If it does, there are 2 cases:
- it belongs to a RESERVED region: the guest should neither use
this address in a MAP not instruct the end-point to DMA on
them. We report an error
- It belongs to an MSI region: we bypass the translation.

This patch implements the PROBE request. At the moment,
only THE RESV_MEM property is handled. The first goal is
to report iommu wide reserved regions such as the MSI regions
set by the machine code. On x86 this will be the IOAPIC MSI
region, [0xFEE00000 - 0xFEEFFFFF], on ARM this may be the ITS
doorbell.
In the future we may introduce per device reserved regions.
This will be useful when protecting host assigned devices
which may expose their own reserved regions

Introduce a new property defining a reserved region:
<low address>:<high address>:<type>.
This will be used to encode reserved IOVA regions.
For instance, in virtio-iommu use case, reserved IOVA regions
will be passed by the machine code to the virtio-iommu-pci
device (an array of those). The type of the reserved region
will match the virtio_iommu_probe_resv_mem subtype value:
- VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0)
- VIRTIO_IOMMU_RESV_MEM_T_MSI (1)
on PC/Q35 machine, this will be used to inform the
virtio-iommu-pci device it should bypass the MSI region.
The reserved region will be: 0xfee00000:0xfeefffff:1.
On ARM, we can declare the ITS MSI doorbell as an MSI
region to prevent MSIs from being mapped on guest side.

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".
