A global boolean variable "vga_interface_created"(declared in softmmu/globals.c)
has been used to track the creation of vga interface. If the vga flag is passed
in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0.
To warn user, the condition checks if vga_interface_created is false
and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the
user regarding the creation of VGA device.
The warning "A -vga option was passed but this
machine type does not use that option; no VGA device has been created"
is logged if vga flag is passed but no vga device is created.
This patch has been tested for x86_64, i386, sparc, sparc64 and arm boards.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

Commit 24f675cd3b ("sparc/sun4m: Use start-powered-off CPUState property") changed
the sun4m CPU reset code to use the start-powered-off property and so split the
creation of the CPU into separate instantiation and realization phases to enable
the new start-powered-off property to be set.
This accidentally broke sun4m machines with more than one CPU present since
sparc_cpu_realizefn() sets a default CPU id, and now that realization occurs after
calling cpu_sparc_set_id() in cpu_devinit() the CPU id gets reset back to the
default instead of being uniquely encoded based upon the CPU number. As soon as
another CPU is brought online, the OS gets confused between them and promptly
panics.
Resolve the issue by moving the cpu_sparc_set_id() call in cpu_devinit() to after
the point where the CPU device has been realized as before.

The sun4m board code connects both of the IRQ outputs of each ESCC to the
same slavio input qemu_irq. Connecting two qemu_irqs outputs directly to the
same input is not valid as it produces subtly wrong behaviour (for instance
if both the IRQ lines are high, and then one goes low, the PIC input will see
this as a high-to-low transition even though the second IRQ line should still
be holding it high).
This kind of wiring needs an explicitly created OR gate; add one.

Currently the GRLIB_IRQMP device is used in one place (the leon3 board),
but instead of the device providing inbound gpio lines for the board
to wire up, the board code itself calls qemu_allocate_irqs() with
the handler function being a set_irq function defined in the code
for the device.
Refactor this into the standard setup of a device having input
gpio lines.
This fixes a trivial Coverity memory leak report (the leon3
board code leaks the IRQ array returned from qemu_allocate_irqs()).

Instead of setting CPUState::halted to 1 in secondary_cpu_reset(), use the
start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.
Now secondary_cpu_reset() becomes equivalent to main_cpu_reset() so rename
the function to sun4m_cpu_reset().
Also remove setting of cs->halted from cpu_devinit(), which seems out of
place when compared to similar code in other architectures (e.g.,
ppce500_init() in hw/ppc/e500.c).
Finally, change creation of CPU object from cpu_create() to object_new()
and qdev_realize_and_unref() because cpu_create() realizes the CPU and it's
not possible to set a property after the object is realized.

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.

Since commit 61f20b9dc5 ("spapr_nvram: Pre-initialize the NVRAM to
support the -prom-env parameter"), pseries machines can pre-initialize
the "system" partition in the NVRAM with the data passed to all -prom-env
parameters on the QEMU command line.
In this case it is assumed that all the data fits in 64 KiB, but the user
can easily pass more and crash QEMU:
$ qemu-system-ppc64 -M pseries $(for ((x=0;x<128;x++)); do \
echo -n " -prom-env " ; printf "%0.sx" {1..1024}; \
done) # this requires ~128 Kib
malloc(): corrupted top size
Aborted (core dumped)
This happens because we don't check if all the prom-env data fits in
the NVRAM and chrp_nvram_set_var() happily memcpy() it passed the
buffer.
This crash affects basically all ppc/ppc64 machine types that use -prom-env:
- pseries (all versions)
- g3beige
- mac99
and also sparc/sparc64 machine types:
- LX
- SPARCClassic
- SPARCbook
- SS-10
- SS-20
- SS-4
- SS-5
- SS-600MP
- Voyager
- sun4u
- sun4v
Add a max_len argument to chrp_nvram_create_system_partition() so that
it can check the available size before writing to memory.
Since NVRAM is populated at machine init, it seems reasonable to consider
this error as fatal. So, instead of reporting an error when we detect that
the NVRAM is too small and adapt all machine types to handle it, we simply
exit QEMU in all cases. This is still better than crashing. If someone
wants another behavior, I guess this can be reworked later.
Tested with:
$ yes q | \
(for arch in ppc ppc64 sparc sparc64; do \
echo == $arch ==; \
qemu=${arch}-softmmu/qemu-system-$arch; \
for mach in $($qemu -M help | awk '! /^Supported/ { print $1 }'); do \
echo $mach; \
$qemu -M $mach -monitor stdio -nodefaults -nographic \
$(for ((x=0;x<128;x++)); do \
echo -n " -prom-env " ; printf "%0.sx" {1..1024}; \
done) >/dev/null; \
done; echo; \
done)
Without the patch, affected machine types cause QEMU to report some
memory corruption and crash:
malloc(): corrupted top size
free(): invalid size
*** stack smashing detected ***: terminated
With the patch, QEMU prints the following message and exits:
NVRAM is too small. Try to pass less data to -prom-env
It seems that the conditions for the crash have always existed, but it
affects pseries, the machine type I care for, since commit 61f20b9dc5
only.
Fixes: 61f20b9dc5 ("spapr_nvram: Pre-initialize the NVRAM to support the -prom-env parameter")

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().

[Two semantic rebase conflicts resolved]
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.

memory_region_allocate_system_memory() API is going away, so
replace it with memdev allocated MemoryRegion. The later is
initialized by generic code, so board only needs to opt in
to memdev scheme by providing
MachineClass::default_ram_id
and using MachineState::ram instead of manually initializing
RAM memory region.
Patch moves ram size check into sun4m_hw_init() and drops
ram_init() moving remainder to sun4m_hw_init() as well,
as it was the only place that called it.
Also it rewrites impl. of RamDevice a little bit, which
could serve as an example of frontend device for RAM backend.
(Caveats are:
1. it doesn't check for memdev backend being mapped
since it's been usurped by generic machine to handle
majority of machines which don't have RAM frontend device
2. it still lacks 'addr' property and still has hardcoded
sysbus_mmio_map() in board init. If done right, board should
set 'addr' property and bus/machine plug handler should map
it during device realize time.
)
Further improvements were left as exercise for the future,
since frontends are out scope of RAM conversion to memdev.
