vfio-pci: Extend reset
Take what we've learned from pci-assign and apply it to vfio-pci.
On reset, disable previous interrupt config, perform a device
reset if available, re-enable INTx, and disable memory regions on
the device to prevent continuing DMA.

monitor: Enable adding an inherited fd to an fd set
qmp_add_fd() gets an fd that was received over a socket with
SCM_RIGHTS and adds it to an fd set. This patch adds support
that will enable adding an fd that was inherited on the
command line to an fd set.
Note: All of the code added to monitor_fdset_add_fd(), with the
exception of the error path for non-valid fdset-id, is code motion
from qmp_add_fd().

pseries: Rework implementation of TCE bypass
On the pseries machine the IOMMU (aka TCE tables) is always active for all
PCI and VIO devices. Mostly to simplify the SLOF firmware, we implement an
extension which allows the IOMMU to be temporarily disabled for certain
devices.
Currently this is implemented by setting the device's DMAContext pointer to
NULL (thus reverting to qemu's default no-IOMMU DMA behaviour), then
replacing it when bypass mode is disabled.
This approach causes a bunch of complications though. It complexifies the
management of the DMAContext lifetimes, it's problematic for savevm/loadvm,
and it means that while bypass is active we have nowhere to store the
device's LIOBN (Logical IO Bus Number, used to identify DMA address
spaces). At present we regenerate the LIOBN from other address information
but this restricts how we can allocate LIOBNs.
This patch gives up on this approach, replacing it with the much simpler
one of having a 'bypass' boolean flag in the TCE state structure.

usb-redir: Add an already_in_flight packet-id queue
After a live migration, the usb-hcd will re-queue all packets by
walking over the schedule in the guest memory again, but requests which
were encountered on the migration source before will already be in flight,
so these should *not* be re-send to the usbredir-host.
This patch adds an already in flight packet ud queue, which will be filled by
the source before migration and then moved over to the migration dest, any
async handled packets are then checked against this queue to avoid sending
the same packet to the usbredir-host twice.

qcow2: Fix return value of alloc_refcount_block
Someone forgot something in commit 29c1a730... Documenting the right
return value is not enough, you also need to actually return it in the
code.
This bug sometimes causes error return values even when everything has
succeeded: The new offset of the refcount block is truncated to 32 bits
and interpreted as signed. At least with small cluster sizes it's easy
to get a negative return value this way.

main-loop: interrupt wait when data arrives on a socket
Right now, the main loop is not interrupted when data arrives on a
socket. To fix this, register each socket to interrupt the main loop
with WSAEventSelect. This does not replace select, it only communicates
a change in socket state that requires a select call.
Since the interrupt fires only once per recv call, or only once
after a send call returns EWOULDBLOCK we can activate it on all events
unconditionally. If QEMU is momentarily uninterested on some condition,
the main loop will not busy wait. Instead, it may get one extra wakeup,
but then it will ignore the condition until progress occurs and/or
qemu_set_fd_handler is called to set a callback. At this point the
condition will be tested via select and the callback will be invoked
even if it is still disabled on the event.

Expose CPUID leaf 7 only for -cpu host
Changes v2 -> v3;
- Check for kvm_enabled() before setting cpuid_7_0_ebx_features
Changes v1 -> v2:
- Use kvm_arch_get_supported_cpuid() instead of host_cpuid() on
cpu_x86_fill_host().
We should use GET_SUPPORTED_CPUID for all bits on "-cpu host"
eventually, but I am not changing all the other CPUID leaves because
we may not be able to test such an intrusive change in time for 1.1.
Description of the bug:
Since QEMU 0.15, the CPUID information on CPUID[EAX=7,ECX=0] is being
returned unfiltered to the guest, directly from the GET_SUPPORTED_CPUID
return value.
The problem is that this makes the resulting CPU feature flags
unpredictable and dependent on the host CPU and kernel version. This
breaks live-migration badly if migrating from a host CPU that supports
some features on that CPUID leaf (running a recent kernel) to a kernel
or host CPU that doesn't support it.
Migration also is incorrect (the virtual CPU changes under the guest's
feet) if you migrate in the opposite direction (from an old CPU/kernel
to a new CPU/kernel), but with less serious consequences (guests
normally query CPUID information only once on boot).
Fortunately, the bug affects only users using cpudefs with level >= 7.
The right behavior should be to explicitly enable those features on
[cpudef] config sections or on the "-cpu" command-line arguments. Right
now there is no predefined CPU model on QEMU that has those features:
the latest Intel model we have is Sandy Bridge.
I would like to get this fixed on 1.1, so I am submitting this patch,
that enables those features only if "-cpu host" is being used (as we
don't have any pre-defined CPU model that actually have those features).
After 1.1 is released, we can make those features properly configurable
on [cpudef] and -cpu configuration.
One problem is: with this patch, users with the following setup:
- Running QEMU 1.0;
- Using a cpudef having level >= 7;
- Running a kernel that supports the features on CPUID leaf 7; and
- Running on a CPU that supports some features on CPUID leaf 7
won't be able to live-migrate to QEMU 1.1. But for these users
live-migration is already broken (they can't live-migrate to hosts with
older CPUs or older kernels, already), I don't see how to avoid this
problem.

serial: fix retry logic
I'm not sure if the retry logic has ever worked when not using FIFO mode. I
found this while writing a test case although code inspection confirms it is
definitely broken.
The TSR retry logic will never actually happen because it is guarded by an
'if (s->tsr_rety > 0)' but this is the only place that can ever make the
variable greater than zero. That effectively makes the retry logic an 'if (0)'.
I believe this is a typo and the intention was >= 0. Once this is fixed though,
I see double transmits with my test case. This is because in the non FIFO
case, serial_xmit may get invoked while LSR.THRE is still high because the
character was processed but the retransmit timer was still active.
We can handle this by simply checking for LSR.THRE and returning early. It's
possible that the FIFO paths also need some attention.

hw/arm_boot.c: Make SMP boards specify address to poll in bootup loop
The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a
pen until the primary CPU releases them. Make boards specify the
address to be polled to determine whether to leave the pen (it was
previously hardcoded to 0x10000030, which is a Versatile Express/
Realview specific system register address).

qdev: Introduce lost tick policy property
Potentially tick-generating timer devices will gain a common property:
lock_tick_policy. It allows to encode 4 different ways how to deal with
tick events the guest did not process in time:
discard - ignore lost ticks (e.g. if the guest compensates for them
already)
delay - replay all lost ticks in a row once the guest accepts them
again
merge - if multiple ticks are lost, all of them are merged into one
which is replayed once the guest accepts it again
slew - lost ticks are gradually replayed at a higher frequency than
the original tick
Not all timer device will need to support all modes. However, all need
to accept the configuration via this common property.

When running 31-bit code we can potentially map the same virtual

This also should be reflected in the tlb invalidation path, so we

omap_intc: Qdevify
Convert the omap_intc devices to qdev. This includes adding
a 'revision' property which will be needed for omap3.
The bulk of this patch is the replacement of "s->irq[x][y]"
with "qdev_get_gpio_in(s->ih[x], y)" now that the interrupt
controller exposes its input lines as qdev gpio inputs.
The devices are named "omap-intc" and "omap2-intc", following
the filename and the OMAP2/3 hardware names, although some
internal functions are still named "omap_inth_*".

x86: use caller supplied CPUState for interrupt related stuff
Several x86 specific functions are called from cpu-exec.c with the
assumption that global env register is valid. This will be changed
later, so make the functions use caller supplied CPUState parameter.
It would be cleaner to move the functions to helper.c, but there are
quite a lot of dependencies between do_interrupt() and other functions.
Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead
of calling the helper (which uses global env, AREG0) directly.

linux-user: Fix initialization of the heap contents when allocating new pages
Technically the new mmapped pages are already initialized to zero
since they are anonymous, however we have to take care with the
contents that come from the remaining part of the previous page: it
may contains garbage data due to a previous heap usage (grown then
shrunken).

when emulating the build process of Perl 5.12.3 on ARMedSlack 13.37:

kvm: ppc: detect old headers
When compiling Qemu with older kernel headers, the PVR setting
mechanism isn't available yet. Unfortunately, back then I didn't add
a capability we could check against, so all we can do is add a configure
test to see if we support PVR setting. For BookE, we don't care yet.
This fixes compilation errors with KVM enabled on older kernel headers
(like 2.6.32).

target-arm: Handle UNDEF cases for Neon invalid modified-immediates
For Neon "one register and a modified immediate value" forms, the
combination op=1 cmode=1111 is unallocated and should UNDEF.
All instructions of this form also UNDEF if Q == 1 and Vd<0> == 1.
We also add a comment on the only UNPREDICTABLE in this space.

target-arm: Fix shift by immediate and narrow where src, dest overlap
For Neon shifts by immediate and narrow, correctly handle the case
where the source registers and the destination registers overlap
(the second pass should use the original register contents, not the
results of the first pass).
This includes a refactoring to pull the size check outside the
loop rather than inside, since there is now very little common
code between the size == 3 and size != 3 case.

Implement the PAPR (pSeries) virtualized interrupt controller (xics)
PAPR defines an interrupt control architecture which is logically divided
into ICS (Interrupt Control Presentation, each unit is responsible for
presenting interrupts to a particular "interrupt server", i.e. CPU) and
ICS (Interrupt Control Source, each unit responsible for one or more
hardware interrupts as numbered globally across the system). All PAPR
virtual IO devices expect to deliver interrupts via this mechanism. In
Linux, this interrupt controller system is handled by the "xics" driver.
On pSeries systems, access to the interrupt controller is virtualized via
hypercalls and RTAS methods. However, the virtualized interface is very
similar to the underlying interrupt controller hardware, and similar PICs
exist un-virtualized in some other systems.
This patch implements both the ICP and ICS sides of the PAPR interrupt
controller. For now, only the hypercall virtualized interface is provided,
however it would be relatively straightforward to graft an emulated
register interface onto the underlying interrupt logic if we want to add
a machine with a hardware ICS/ICP system in the future.
There are some limitations in this implementation: it is assumed for now
that only one instance of the ICS exists, although a full xics system can
have several, each responsible for a different group of hardware irqs.
ICP/ICS can handle both level-sensitve (LSI) and message signalled (MSI)
interrupt inputs. For now, this implementation supports only MSI
interrupts, since that is used by PAPR virtual IO devices.

block: add logical_block_size property
Add a logical block size attribute as various guest side tools only
increase the filesystem sector size based on it, not the advisory
physical block size.
For scsi we already have support for a different logical block size
in place for CDROMs that we can built upon. Only my recent block
device characteristics VPD page needs some fixups. Note that we
leave the logial block size for CDROMs hardcoded as the 2k value
is expected for it in general.
For virtio-blk we already have a feature flag claiming to support
a variable logical block size that was added for the s390 kuli
hypervisor. Interestingly it does not actually change the units
in which the protocol works, which is still fixed at 512 bytes,
but only communicates a different minimum I/O granularity. So
all we need to do in virtio is to add a trap for unaligned I/O
and round down the device size to the next multiple of the logical
block size.
IDE does not support any other logical block size than 512 bytes.

block: separate raw images from the file protocol
We're running into various problems because the "raw" file access, which
is used internally by the various image formats is entangled with the
"raw" image format, which maps the VM view 1:1 to a file system.
This patch renames the raw file backends to the file protocol which
is treated like other protocols (e.g. nbd and http) and adds a new
"raw" image format which is just a wrapper around calls to the underlying
protocol.
The patch is surprisingly simple, besides changing the probing logical
in block.c to only look for image formats when using bdrv_open and
renaming of the old raw protocols to file there's almost nothing in there.
For creating images, a new bdrv_create_file is introduced which guesses the
protocol to use. This allows using qemu-img create -f raw (or just using the
default) for both files and host devices. Converting the other format drivers
to use this function to create their images is left for later patches.
The only issues still open are in the handling of the host devices.
Firstly in current qemu we can specifiy the host* format names
on various command line acceping images, but the new code can't
do that without adding some translation. Second the layering breaks
the no_zero_init flag in the BlockDriver used by qemu-img. I'm not
happy how this is done per-driver instead of per-state so I'll
prepare a separate patch to clean this up.
There's some more cleanup opportunity after this patch, e.g. using
separate lists and registration functions for image formats vs
protocols and maybe even host drivers, but this can be done at a
later stage.
Also there's a check for protocol in bdrv_open for the BDRV_O_SNAPSHOT
case that I don't quite understand, but which I fear won't work as
expected - possibly even before this patch.
Note that this patch requires various recent block patches from Kevin
and me, which should all be in his block queue.

Add test suite for json marshalling
By reusing the qjson test suite. After checking that we can demarshal, marshal
again and compared to the expected decoded value. This doesn't work so well
for floats because they cannot be accurately represented in decimal but we
try our best.

monitor: QError support
This commit adds QError support in the Monitor.
A QError member is added to the Monitor struct. This new member
stores error information and is also used to check if an error
has occurred when the called handler returns.
Additionally, a new macro called qemu_error_new() is introduced.
It builds on top of the QemuErrorSink API and should be used in
place of qemu_error().
When all conversion to qemu_error_new() is done, qemu_error() can
be turned private.
Basically, Monitor's error flow is something like this:
1. An error occurs in the handler, it calls qemu_error_new()
2. qemu_error_new() builds a new QError object and stores it in
the Monitor struct
3. The handler returns
4. Top level Monitor code checks the Monitor struct and calls
qerror_print() to print the error

qemu-io: reject invalid pattern
Replace the use of atoi which is used for pattern parsing currently with
strtol. Atoi won't parse sedecimal pattern values (it always returns 0),
but qemu-iotests use such pattern values. Also reject every pattern
that is not a unsigned char as we pass the pattern to memset which
expect a bye value (despite having the pattern argument declared as int).
Based on an earlier patch by Stefan Weil which did not include the
error handling.

Add cpu model configuration support..
This is a reimplementation of prior versions which adds
the ability to define cpu models for contemporary processors.
The added models are likewise selected via -cpu <name>,
and are intended to displace the existing convention
of "-cpu qemu64" augmented with a series of feature flags.
A primary motivation was determination of a least common
denominator within a given processor class to simplify guest
migration. It is still possible to modify an arbitrary model
via additional feature flags however the goal here was to
make doing so unnecessary in typical usage. The other
consideration was providing models names reflective of
current processors. Both AMD and Intel have reviewed the
models in terms of balancing generality of migration vs.
excessive feature downgrade relative to released silicon.
This version of the patch replaces the prior hard wired
definitions with a configuration file approach for new
models. Existing models are thus far left as-is but may
easily be transitioned to (or may be overridden by) the
configuration file representation.
Proposed new model definitions are provided here for current
AMD and Intel processors. Each model consists of a name
used to select it on the command line (-cpu <name>), and a
model_id which corresponds to a least common denominator
commercial instance of the processor class.
A table of names/model_ids may be queried via "-cpu ?model":
:
x86 Opteron_G3 AMD Opteron 23xx (Gen 3 Class Opteron)
x86 Opteron_G2 AMD Opteron 22xx (Gen 2 Class Opteron)
x86 Opteron_G1 AMD Opteron 240 (Gen 1 Class Opteron)
x86 Nehalem Intel Core i7 9xx (Nehalem Class Core i7)
x86 Penryn Intel Core 2 Duo P9xxx (Penryn Class Core 2)
x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2)
:
Also added is "-cpu ?dump" which exhaustively outputs all config
data for all defined models, and "-cpu ?cpuid" which enumerates
all qemu recognized CPUID feature flags.
The pseudo cpuid flag 'check' when added to the feature flag list
will warn when feature flags (either implicit in a cpu model or
explicit on the command line) would have otherwise been quietly
unavailable to a guest:
# qemu-system-x86_64 ... -cpu Nehalem,check
warning: host cpuid 0000_0001 lacks requested flag 'sse4.2|sse4_2' [0x00100000]
warning: host cpuid 0000_0001 lacks requested flag 'popcnt' [0x00800000]
A similar 'enforce' pseudo flag exists which in addition
to the above causes qemu to error exit if requested flags are
unavailable.
Configuration data for a cpu model resides in the target config
file which by default will be installed as:
/usr/local/etc/qemu/target-<arch>.conf
The format of this file should be self explanatory given the
definitions for the above six models and essentially mimics
the structure of the static x86_def_t x86_defs.
Encoding of cpuid flags names now allows aliases for both the
configuration file and the command line which reconciles some
Intel/AMD/Linux/Qemu naming differences.
This patch was tested relative to qemu.git.

qemu/pci: make default_write_config use mask table
Change much of hw/pci to use symbolic constants and a table-driven
design: add a mask table with writable bits set and readonly bits unset.
Detect change by comparing original and new registers.
This makes it easy to support capabilities where read-only/writeable
bit layout differs between devices, depending on capabilities present.
As a result, writing a single byte in BAR registers now works as
it should. Writing to upper limit registers in the bridge
also works as it should. Code is also shorter.
