target/openrisc: Support non-busy idle state using PMR SPR
The OpenRISC architecture has the Power Management Register (PMR)
special purpose register to manage cpu power states. The interesting
modes are:
* Doze Mode (DME) - Stop cpu except timer & pic - wake on interrupt
* Sleep Mode (SME) - Stop cpu and all units - wake on interrupt
* Suspend Model (SUME) - Stop cpu and all units - wake on reset
The linux kernel will set DME when idle.
This patch implements the PMR SPR and halts the qemu cpu when there is a
change to DME or SME. This means that openrisc qemu in no longer peggs
a host cpu at 100%.
In order for this to work we need to kick the CPU when timers are
expired. Update the cpu timer to kick the cpu upon each timer event.

target/openrisc: Remove duplicate features property
The features property has stored the exact same thing as the cpucfgr
spr. Remove the feature enum and property as it is not needed.
In order to preserve the behavior or keeping features accross reset this
patch moves cpucfgr into the non reset region of the state struct. Since
the cpucfgr is read only this means we only need to sset cpucfgr once
during class init.
target/openrisc: Implement full vmstate serialization
Previously serialization did not persist the tlb, timer, pic and other
key state items. This meant snapshotting and restoring a running os
would crash. After adding these I am able to take snapshots of a
running linux os and restore at a later time.
I am currently not trying to maintain capatibility with older versions
as I do not believe this really worked before or anyone used it.
Shadow registers are part of the openrisc spec along with sr[cid], as
part of the fast context switching feature. When exceptions occur,
instead of having to save registers to the stack if enabled the CID will
increment and a new set of registers will be available.
This patch only implements shadow registers which can be used as extra
scratch registers via the mfspr and mtspr if required. This is
implemented in a way where it would be easy to add on the fast context
switching, currently cid is hardcoded to 0.
This is need for openrisc linux smp kernels to boot correctly.
In openRISC we are implementing the shadow registers as a 2d array.
Using this target long method rather than direct 32-bit alternatives is
consistent with the rest of our vm state serialization logic.
These are used to identify the processor in SMP system. Their
definition has been defined in verilog cores but it not yet part of the
spec but it will be soon.
The proposal for this is available:

This patch enables 8-byte writes and reads to VFIO. Such implemention
is already done but it's missing the 'case' to handle such accesses in
both vfio_region_write and vfio_region_read and the MemoryRegionOps:
impl.max_access_size and impl.min_access_size.
vfio: Set MemoryRegionOps:max_access_size and min_access_size
Sets valid.max_access_size and valid.min_access_size to ensure safe
8-byte accesses to vfio. Today, 8-byte accesses are broken into pairs
of 4-byte calls that goes unprotected:
This happens because the 8-byte write should be broken into 4-byte
writes by memory.c:access_with_adjusted_size() in order to be under
the same lock. Today, it's done in exec.c:address_space_write_continue()
which was able to handle only 4 bytes due to a zero'ed
valid.max_access_size (see exec.c:memory_access_size()).

input: Add trace event for empty keyboard queue
When driving QEMU from the outside, we have basically no chance to
determine how quickly the guest OS picks up key events, so we usually

the guest always has enough chance to pick them up.

qemu_input_event_send() discards key event when the guest is paused,
but not the delay.
The delay ends up in the input queue, and qemu_input_event_send_key()
will further fill the queue with upcoming events.
VNC uses qemu_input_event_send_key_delay(), not SPICE, which results
in a different input behaviour on pause: VNC will queue the events
(except the first that is discarded), SPICE will discard all events.
Don't queue delay if paused, and provide same behaviour on SPICE and
VNC clients on resume (and potentially avoid over-allocating the
buffer queue)
The problem is that the code in s390_gen_initial_iplb() currently assumes
that all SCSI devices are also CCW devices, which is not the case for
virtio-scsi-pci of course. Fix it by adding an appropriate check for
TYPE_CCW_DEVICE here.

qcow2: Allow discard of final unaligned cluster
As mentioned in commit 0c1bd46, we ignored requests to
discard the trailing cluster of an unaligned image. While
discard is an advisory operation from the guest standpoint,
(and we are therefore free to ignore any request), our
qcow2 implementation exploits the fact that a discarded
cluster reads back as 0. As long as we discard on cluster
boundaries, we are fine; but that means we could observe
non-zero data leaked at the tail of an unaligned image.
Enhance iotest 66 to cover this case, and fix the implementation
to honor a discard request on the final partial cluster.

qemu-img/convert: Move bs_n > 1 && -B check down
It does not make much sense to use a backing image for the target when
you concatenate multiple images (because then there is no correspondence
between the source images' backing files and the target's); but it was
still possible to give one by using -o backing_file=X instead of -B X.
Fix this by moving the check.
(Also, change the error message because -B is not the only way to
specify the backing file, evidently.)

qemu-img/convert: Use @opts for one thing only
After storing the creation options for the new image into @opts, we
fetch some things for our own information, like the backing file name,
or whether to use encryption or preallocation.
With the -n parameter, there will not be any creation options; this is
not too bad because this just means that querying a NULL @opts will
always return the default value.
However, we also use @opts for the --object options. Therefore, @opts is
not necessarily NULL if -n was specified; instead, it may contain those
options. In practice, this probably does not cause any problems because
there most likely is no object that supports any of the parameters we
query here, but this is neither something we should rely on nor does
this variable reuse make the code very nice to read.
Therefore, just use a separate variable for the --object options.

block: Do not unref bs->file on error in BD's open
The block layer takes care of removing the bs->file child if the block
driver's bdrv_open()/bdrv_file_open() implementation fails. The block
driver therefore does not need to do so, and indeed should not unless it
sets bs->file to NULL afterwards -- because if this is not done, the
bdrv_unref_child() in bdrv_open_inherit() will dereference the freed
memory block at bs->file afterwards, which is not good.
We can now decide whether to add a "bs->file = NULL;" after each of the
offending bdrv_unref_child() invocations, or just drop them altogether.
The latter is simpler, so let's do that.

subtle timing of the completion of read and write issued in the first
