there are 2 use cases to deal with:
1: fixed CPU models per board/soc
2: boards with user configurable cpu_model and fallback to
default cpu_model if user hasn't specified one explicitly
For the 1st
drop intermediate cpu_model parsing and use const cpu type
directly, which replaces:
typename = object_class_get_name(
cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
object_new(typename)
with
object_new(FOO_CPU_TYPE_NAME)
or
cpu_generic_init(BASE_CPU_TYPE, "my cpu model")
with
cpu_create(FOO_CPU_TYPE_NAME)
as result 1st use case doesn't have to invoke not necessary
translation and not needed code is removed.
For the 2nd
1: set default cpu type with MachineClass::default_cpu_type and
2: use generic cpu_model parsing that done before machine_init()
is run and:
2.1: drop custom cpu_model parsing where pattern is:
typename = object_class_get_name(
cpu_class_by_name(TYPE_ARM_CPU, cpu_model))
[parse_features(typename, cpu_model, &err) ]
2.2: or replace cpu_generic_init() which does what
2.1 does + create_cpu(typename) with just
create_cpu(machine->cpu_type)
as result cpu_name -> cpu_type translation is done using
generic machine code one including parsing optional features
if supported/present (removes a bunch of duplicated cpu_model
parsing code) and default cpu type is defined in an uniform way
within machine_class_init callbacks instead of adhoc places
in boadr's machine_init code.

Set the MachineClass flag ignore_memory_transaction_failures
for almost all ARM boards. This means they retain the legacy
behaviour that accesses to unimplemented addresses will RAZ/WI
rather than aborting, when a subsequent commit adds support
for external aborts.
The exceptions are:
* virt -- we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables
* mps2 -- this board was written to use unimplemented-device
for all the ranges with devices we don't yet handle
New boards should not set the flag, but instead be written
like the mps2.

Instead of migrating the flash by creating the memory region
with memory_region_init_ram_nomigrate() and then calling
vmstate_register_ram_global(), just use memory_region_init_ram(),
which now handles migration registration automatically.
This is a migration compatibility break for the integratorcp
board, because the RAM region's migration name changes to
include the device path. This is OK because we don't guarantee
migration compatibility for this board.

Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.
It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.
Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Symptom:
$ qemu-system-x86_64 -m 10000000
Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
Aborted (core dumped)
Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions. Before the commit, we report the error and exit(1), in
one place, ram_block_add(). The commit lifts the error handling up
the call chain some, to three places. Fine. Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".
The three places are:
* memory_region_init_ram()
Commit 4994653 (right after commit ef701d7) lifted the error
handling further, through memory_region_init_ram(), multiplying the
incorrect use of &error_abort. Later on, imitation of existing
(bad) code may have created more.
* memory_region_init_ram_ptr()
The &error_abort is still there.
* memory_region_init_rom_device()
Doesn't need fixing, because commit 33e0eb5 (soon after commit
ef701d7) lifted the error handling further, and in the process
changed it from &error_abort to passing it up the call chain.
Correct, because the callers are realize() methods.
Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:
@r@
expression mr, owner, name, size, err;
position p;
@@
memory_region_init_ram(mr, owner, name, size,
(
- &error_abort
+ &error_fatal
|
err@p
)
);
@script:python@
p << r.p;
@@
print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)
When the last argument is &error_abort, it gets replaced by
&error_fatal. This is the fix.
If the last argument is anything else, its position is reported. This
lets us check the fix is complete. Four positions get reported:
* ram_backend_memory_alloc()
Error is passed up the call chain, ultimately through
user_creatable_complete(). As far as I can tell, it's callers all
handle the error sanely.
* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()
DeviceClass.realize() methods, errors handled sanely further up the
call chain.
We're good. Test case again behaves:
$ qemu-system-x86_64 -m 10000000

Therefore for any board that uses memory_region_init_ram directly,

Currently for both qemu-system-arm and qemu-system-aarch64
the default board model if the user doesn't specify one
is the 'integratorcp'. This is a totally arbitrary historical
accident since it was the first board to be modelled.
That board is now just one target among many for us, and
is a very poor choice of default:
* it's an ancient board that is now only found in the
junkpiles of longtime ARM/Linux hackers, if at all
* it's an ARMv5 CPU, when most distros are now assuming
ARMv7
* it's pretty much unmaintained in QEMU
* it doesn't even have versatilepb's advantage of
supporting PCI
Making it or any other board the default serves only
to confuse people new to ARM who expect something more
like the x86 monoculture. Remove the is_default marker
from integratorcp, and don't set it for any other board,
to give users a nudge that they need to think about
which board they want a QEMU model of. (QEMU will produce
the admittedly slightly cryptic error "No machine found.")

We set default boot order "cad" in every single machine definition

care for boot order, and "cad" makes sense for even fewer.
Machines that care:
* pc and its variants
Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
'c', 'd' and 'n'. Reject all others (fatal with -boot).
* nseries (n800, n810)
Check whether order starts with 'n'. Silently ignored otherwise.
* prep, g3beige, mac99
Extract the first character the machine understands (subset of
'a'..'f'). Silently ignored otherwise.
* spapr
Accept an arbitrary string (vl.c restricts it to contain only
'a'..'p', no duplicates).
* sun4[mdc]
Use the first character. Silently ignored otherwise.
Strip characters these machines ignore from their default boot order.
For all other machines, remove the unused default boot order
alltogether.
Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.
