Since
commit 04920fc0fa
loader: store FW CFG ROM files in RAM
RAM MRs including ROM files in FW CFGs are created
and named using the file basename.
This becomes problematic if these names are
supplied by user, since the basename might not
be unique.
There are two cases we care about:
- option-rom flag.
- option ROM for devices. This triggers e.g. when
using rombar=0.
At the moment we get an assert. E.g
qemu -option-rom /usr/share/ipxe/8086100e.rom -option-rom
/usr/share/ipxe.efi/8086100e.rom
RAMBlock "/rom@genroms/8086100e.rom" already registered, abort!
This is a regression from 1.6.
For now let's keep it simple and just avoid creating the
MRs in case of option ROMs.
when using 1.7 machine types, enable
option ROMs in RAM to match that version.

Implement WFE to yield our timeslice to the next CPU.
This avoids slowdowns in multicore configurations caused
by one core busy-waiting on a spinlock which can't possibly
be unlocked until the other core has an opportunity to run.
This speeds up my test case A15 dual-core boot by a factor
of three (though it is still four or five times slower than

Windows XP shows COM2 port as non functional in
"Device Manager" although no COM2 port backing device
is present in QEMU.
This regression is really due to
3bb28b7208b349e7a1b326e3c6ef9efac1d462bf?
memory: Provide separate handling of unassigned io ports accesses
That is caused by the fact that QEMU reports to
OSPM that device is present by setting 5th bit in
PII4XPM.pci_conf[0x67] register when COM2 doesn't
exist.
It happens due to memory_region_present(io_as, 0x2f8)
returning false positive since 0x2f8 address eventually
translates into catchall io_as address space.
Fix memory_region_present(parent, addr) by returning
true only if addr maps into a MemoryRegion within
parent (excluding parent itself), to match its
doc comment.
While at it fix copy/paste error in
memory_region_present() doc comment.
Note: this is a temporary hack: we really need better handling for
unassigned regions, we should avoid fallback regions since they are bad
for performance (breaking radix tree assumption that the data structure
is sparsely populated); for memory we need to fix this to implement PCI
master abort properly, anyway.

When we have 2 separate qdev devices that both create a qbus of the
same type without specifying a bus name or device name, we end up
with two buses of the same name, such as ide.0 on the Mac machines:
dev: macio-ide, id ""
bus: ide.0
type IDE
dev: macio-ide, id ""
bus: ide.0
type IDE
If we now spawn a device that connects to a ide.0 the last created
bus gets the device, with the first created bus inaccessible to the
command line.
After some discussion on IRC we concluded that the best quick fix way
forward for this is to make automated bus-class type based allocation
count a global counter. That's what this patch implements. With this
we instead get
dev: macio-ide, id ""
bus: ide.1
type IDE
dev: macio-ide, id ""
bus: ide.0
type IDE
on the example mentioned above.
This also means that if you did -device ...,bus=ide.0 you got a device
on the first bus (the last created one) before this patch and get that
device on the second one (the first created one) now. Breaks
migration unless you change bus=ide.0 to bus=ide.1 on the destination.
This is intended and makes the bus enumeration work as expected.
As per review request follows a list of otherwise affected boards and
the reasoning for the conclusion that they are ok:
target machine bus id times
------ ------- ------ -----
aarch64 n800 i2c-bus.0 2
aarch64 n810 i2c-bus.0 2
arm n800 i2c-bus.0 2
arm n810 i2c-bus.0 2
-> Devices are only created explicitly on one of the two buses, using
s->mpu->i2c[0], so no change to the guest.
aarch64 vexpress-a15 virtio-mmio-bus.0 4
aarch64 vexpress-a9 virtio-mmio-bus.0 4
aarch64 virt virtio-mmio-bus.0 32
arm vexpress-a15 virtio-mmio-bus.0 4
arm vexpress-a9 virtio-mmio-bus.0 4
arm virt virtio-mmio-bus.0 32
-> Makes -device bus= work for all virtio-mmio buses. Breaks
migration. Workaround for migration from old to new: specify
virtio-mmio-bus.4 or .32 respectively rather than .0 on the
destination.
aarch64 xilinx-zynq-a9 usb-bus.0 2
arm xilinx-zynq-a9 usb-bus.0 2
mips64el fulong2e usb-bus.0 2
-> Normal USB operation not affected. Migration driver needs command
line to use the other bus.

The existing load_elf() just returns -1 if it fails to load ELF. However
it could be smarter than this and tell more about the failure such as
wrong endianness or incompatible platform.
This adds additional return codes for wrong architecture, wrong
endianness and if the image is not ELF at all.
This adds a load_elf_strerror() helper to convert return codes into
string messages.
This fixes handling of what load_elf() returns for s390x, other
callers just check the return value for <0 and this remains unchanged.

Older gcc versions (such as the one in SLES11) get confused when you declare

To work around that limitation, let's extract the QEMUMachine typedef into a
separate header file that is guarded by preprocessor duplicate include checks.
This fixes the following type of compile errors for me:

The function qobject_from_json() doesn't actually allow its
argument to be a format string -- it passes a NULL va_list*
to qobject_from_jsonv(), and the parser code will then never
actually interpret %-escape sequences (it tests whether the
va_list pointer is NULL and will stop with a parse error).
The spurious attribute markup causes clang warnings in some
of the test cases where we programmatically construct JSON
to feed to qobject_from_json():
tests/test-qmp-input-visitor.c:76:35: warning: format string is not a
string literal (potentially insecure) [-Wformat-security]
data->obj = qobject_from_json(json_string);

The functions use uint16_t or uint32_t values, so show this in the function
prototypes. Non-optimizing compilers will avoid unnecessary type
conversions when generating calls of these inline functions.
stq_le_p, stq_be_p already use similar prototypes.

The function uses an uint8_t value, so show this in the function
prototype. Non-optimizing compilers will avoid unnecessary type
conversions from (u)int8_t to int and back to uint8_t when generating
calls of this inline function.
stw_p, stl_p and stq_p already use similar prototypes.

1st and 2nd dump_bitmap are same, because dump level is specified to 1 here.
