e06054368c hw: Remove superfluous includes of hw/hw.h
The include/hw/hw.h header only has a prototype for hw_error(),
so it does not make sense to include this in files that do not
use this function.

d895d25ae2 s390x: css: report errors from ccw_dstream_read/write
ccw_dstream_read/write functions returned values are sometime
not taking into account and reported back to the upper level
of interpretation of CCW instructions.

It follows that accessing an invalid address does not trigger
a subchannel status program check to the guest as it should.

Let's test the return values of ccw_dstream_write[_buf] and
ccw_dstream_read[_buf] and report it to the caller.

e6fa978d83 hw/arm/virt: Disable pl011 clock migration if needed
A clock is added by commit aac63e0e6e ("hw/char/pl011: add a clock
input") since v5.2.0 which corresponds to virt-5.2 machine type. It
causes backwards migration failure from upstream to downstream (v5.1.0)
when the machine type is specified with virt-5.1.

This fixes the issue by following instructions from section "Connecting
subsections to properties" in docs/devel/migration.rst. With this applied,
the PL011 clock is migrated based on the machine type.

   virt-5.2 or newer:  migration
   virt-5.1 or older:  non-migration

e178113ff6 hw: Replace anti-social QOM type names
Several QOM type names contain ',':

    ARM,bitband-memory
    etraxfs,pic
    etraxfs,serial
    etraxfs,timer
    fsl,imx25
    fsl,imx31
    fsl,imx6
    fsl,imx6ul
    fsl,imx7
    grlib,ahbpnp
    grlib,apbpnp
    grlib,apbuart
    grlib,gptimer
    grlib,irqmp
    qemu,register
    SUNW,bpp
    SUNW,CS4231
    SUNW,DBRI
    SUNW,DBRI.prom
    SUNW,fdtwo
    SUNW,sx
    SUNW,tcx
    xilinx,zynq_slcr
    xlnx,zynqmp
    xlnx,zynqmp-pmu-soc
    xlnx,zynq-xadc

These are all device types.  They can't be plugged with -device /
device_add, except for xlnx,zynqmp-pmu-soc, and I doubt that one
actually works.

They *can* be used with -device / device_add to request help.
Usability is poor, though: you have to double the comma, like this:

    $ qemu-system-x86_64 -device SUNW,,fdtwo,help

Trap for the unwary.  The fact that this was broken in
device-introspect-test for more than six years until commit e27bd49876
fixed it demonstrates that "the unwary" includes seasoned developers.

One QOM type name contains ' ': "ICH9 SMB".  Because having to
remember just one way to quote would be too easy.

Rename the "SUNW,FOO types to "sun-FOO".  Summarily replace ',' and '
' by '-' in the other type names.

5ee0abed51 clock: Add ClockEvent parameter to callbacks
The Clock framework allows users to specify a callback which is
called after the clock's period has been updated.  Some users need to
also have a callback which is called before the clock period is
updated.

As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.

Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

f2c0fb93a4 hw/char/exynos4210_uart: Fix missing call to report ready for input
When the frontend device has no space for a read the fd is removed
from polling to allow time for the guest to read and clear the buffer.
Without the call to qemu_chr_fe_accept_input(), the poll will not be
broken out of when the guest has cleared the buffer causing significant
IO delays that get worse with smaller buffers.

40b4c2ae90 hw/char/exynos4210_uart: Fix buffer size reporting with FIFO disabled
Currently the Exynos 4210 UART code always reports available FIFO space
when the backend checks for buffer space. When the FIFO is disabled this
is behavior causes the backend chardev code to replace the data before the
guest can read it.

This patch changes adds the logic to report the capacity properly when the
FIFO is not being used.

29daa894b6 hw/char/serial: Clean up unnecessary code
Since commit 5ec3a23e6c ("serial: convert PIO to new memory
api read/write") we don't need to worry about accesses bigger
than 8-bit. Use the extract()/deposit() functions to access
the correct part of the 16-bit 'divider' register.

3059344f01 hw/char/bcm2835_aux: Allow less than 32-bit accesses
The "BCM2835 ARM Peripherals" datasheet [*] chapter 2
("Auxiliaries: UART1 & SPI1, SPI2"), list the register
sizes as 3/8/16/32 bits. We assume this means this
peripheral allows 8-bit accesses.

This was not an issue until commit 5d971f9e67 which reverted
("memory: accept mismatching sizes in memory_region_access_valid").

The model is implemented as 32-bit accesses (see commit 97398d900c,
all registers are 32-bit) so replace MemoryRegionOps.valid as
MemoryRegionOps.impl, and re-introduce MemoryRegionOps.valid
with a 8/32-bit range.

[*] https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf

f2336b5fbd hw/char/serial: Rename I/O read/write trace events
The serial_mm_read/write() handlers from the TYPE_SERIAL_MM device
call the serial_ioport_read/write() handlers with shifted offset.

When looking at the trace events from this MMIO device, it is
confusing to read the accesses as I/O. Simplify using generic
trace event names which make sense the various uses.

6ab9be1ec1 hw/char/serial: Assert serial_ioport_read/write offset fits 8 bytes
The serial device has 8 registers, each 8-bit. The MemoryRegionOps
'serial_io_ops' is initialized with max_access_size=1, and all
memory_region_init_io() callers correctly set the region size to
8 bytes:
- serial_io_realize
- serial_isa_realizefn
- serial_pci_realize
- multi_serial_pci_realize

It is safe to assert the offset argument of serial_ioport_read()
and serial_ioport_write() is always less than 8.

when we neglect to update trace-events for code motion, or add events

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

These were designed to facilitate testing but should provide enough
function to be useful in other contexts.  Only a subset of the functions
of each peripheral is implemented, mainly due to the lack of a standard
way to handle electrical connections (like GPIO pins).

668f62ec62 error: Eliminate error_propagate() with Coccinelle, part 1
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.  Convert

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
hw/riscv/sifive_e.c.

9bc6bfdf67 qdev: Drop qbus_set_hotplug_handler() parameter @errp
qbus_set_hotplug_handler() is a simple wrapper around
object_property_set_link().

object_property_set_link() fails when the property doesn't exist, is
not settable, or its .check() method fails.  These are all programming
errors here, so passing &error_abort to qbus_set_hotplug_handler() is
appropriate.

Most of its callers do.  Exceptions:

* pcie_cap_slot_init(), shpc_init(), spapr_phb_realize() pass NULL,
  i.e. they ignore errors.

* spapr_machine_init() passes &error_fatal.

* s390_pcihost_realize(), virtio_serial_device_realize(),
  s390_pcihost_plug() pass the error to their callers.  The latter two
  keep going after the error, which looks wrong.

Drop the @errp parameter, and instead pass &error_abort to
object_property_set_link().
