ide: add limit to .prepare_buf()
prepare_buf should not always grab as many descriptors
as it can, sometimes it should self-limit.
For example, an NCQ transfer of 1 sector with a PRDT that
describes 4GiB of data should not copy 4GiB of data, it
should just transfer that first 512 bytes.
PIO is not affected, because the dma_buf_rw dma helpers
already have a byte limit built-in to them, but DMA/NCQ
will exhaust the entire list regardless of requested size.
AHCI 1.3 specifies in section 6.1.6 Command List Underflow that
NCQ is not required to detect underflow conditions. Non-NCQ
pathways signal underflow by writing to the PRDBC field, which
will already occur by writing the actual transferred byte count
to the PRDBC, signaling the underflow.
Our NCQ pathways aren't required to detect underflow, but since our DMA
backend uses the size of the PRDT to determine the size of the transer,
if our PRDT is bigger than the transaction (the underflow condition) it
doesn't cost us anything to detect it and truncate the PRDT.
This is a recoverable error and is not signaled to the guest, in either
NCQ or normal DMA cases.
For BMDMA, the existing pathways should see no guest-visible difference,
but any bytes described in the overage will no longer be transferred
before indicating to the guest that there was an underflow.

ahci: Do not ignore memory access read size
The only guidance the AHCI specification gives on memory access is:
"Register accesses shall have a maximum size of 64-bits; 64-bit access
must not cross an 8-byte alignment boundary."
I interpret this to mean that aligned or unaligned 1, 2 and 4 byte
accesses should work, as well as aligned 8 byte accesses.
In practice, a real Q35/ICH9 responds to 1, 2, 4 and 8 byte reads
regardless of alignment. Windows 7 can be observed making 1 byte
reads to the middle of 32 bit registers to fetch error codes.
Introduce a wrapper to support unaligned accesses to AHCI.
This wrapper will support aligned 8 byte reads, but will make
no effort to support unaligned 8 byte reads, which although they
will work on real hardware, are not guaranteed to work and do
not appear to be used by either Windows or Linux.

The section footer changes commit f68945d42bab ("Add a protective

on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.
s390x/gdb: synchronize cpu state after modifying acrs
Whenever we touch the access control registers, we have to make sure that
the values will make it into kvm. Otherwise the change will simply be lost.
When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take
care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync,
so the values will directly be written to kvm. The performance overhead can
be ignored and this is much cleaner than manually writing these registers to kvm
via our two supported ways.
commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

hw/arm/virt: Make block devices default to virtio

device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug

virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:

hw/mips: Do not clear BEV for MIPS malta kernel load
The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

qemu-iotests: fix 051.out after qdev error message change
Commit f006cf7fa9a63ba8e4ccf57d46231ce594301727 ("qdev-monitor:
Propagate errors through qdev_device_add()") dropped a meaningless error
message. This change in output caused qemu-iotests 051 to fail:
QEMU_PROG: -device ide-drive,drive=disk: Device initialization failed.
-QEMU_PROG: -device ide-drive,drive=disk: Device 'ide-drive' could not be initialized
A typo means that the tests dependent on glib with subprocess
support are never run.
