object_initialize() leaves the object with a refcount of 1.
object_property_add_child() adds its own reference which is dropped
again when the property is deleted.

Slow BAR access path is used when VFIO fails to mmap() BAR.
Since this is just a transport between the guest and a device, there is
no need to do endianness swapping.
This changes BARs to use native endianness. Since non-ROM BARs were
doing byte swapping, we need to remove it so does the patch.
As the result, this eliminates cancelling byte swaps and there is
no change in behavior for non-ROM BARs.
ROM BARs were declared little endian too but byte swapping was not
implemented for them so they never actually worked on big endian systems
as there was no cancelling byte swap. This fixes endiannes for ROM BARs
by declaring them native endian and only fixing access sizes as it is
done for non-ROM BARs.

There are still old guests out there that over-exercise MSI-X masking.
The current code completely sets-up and tears-down an MSI-X vector on
the "use" and "release" callbacks. While this is functional, it can
slow an old guest to a crawl. We can easily skip the KVM parts of
this so that we keep the MSI route and irqfd setup. We do however
need to switch VFIO to trigger a different eventfd while masked.
Actually, we have the option of continuing to use -1 to disable the
trigger, but by using another EventNotifier we can allow the MSI-X
core to emulate pending bits and re-fire the vector once unmasked.
MSI code gets updated as well to use the same setup and teardown
structures and functions.
Prior to this change, an igbvf assigned to a RHEL5 guest gets about
20Mbps and 50 transactions/s with netperf (remote or VF->PF). With
this change, we get line rate and 3k transactions/s remote or 2Gbps
and 6k+ transactions/s to the PF. No significant change is expected
for newer guests with more well behaved MSI-X support.

$ ./test_poll
In callback
On FreeBSD instead, the callback never gets called:
$ ./test_poll
So, in order to workaround this, poll the source with G_IO_HUP (which
makes the code behave the same way on both Linux and FreeBSD).

Some CPU families can dynamically change their endianness. This means we
can have little endian ppc or big endian arm guests for example. This has
an impact on legacy virtio data structures since they are target endian.
We hence introduce a new property to track the endianness of each virtio
device. It is reasonnably assumed that endianness won't change while the
device is in use : we hence capture the device endianness when it gets
reset.
We migrate this property in a subsection, after the device descriptor. This
means the load code must not rely on it until it is restored. As a consequence,
the vring sanity checks had to be moved after the call to vmstate_load_state().
We enforce paranoia by poisoning the property at the begining of virtio_load().

There is a need to add some more fields to VirtIODevice that should be
migrated (broken status, endianness). The problem is that we do not
want to break compatibility while adding a new feature... This issue has
been addressed in the generic VMState code with the use of optional
subsections. As a *temporary* alternative to port the whole virtio
migration code to VMState, this patch mimics a similar subsectionning
ability for virtio, using the VMState code.
Since each virtio device is streamed in its own section, the idea is to
stream subsections between the end of the device section and the start
of the next sections. This allows an older QEMU to complain and exit
when fed with subsections:

- new field mmap_offset is added to the VhostUserMemoryRegion. It

- other fileds in VhostUserMemoryRegion struct are not changed, as
they are all needed for usermode app implementation
- region data is not taken from ram_list.blocks anymore, instead we

- Now multiple regions can have same FD and user applicaton can call

For each compat property on PC_Q35_COMPAT_*, there are only two
possibilities:
* If the device is never instantiated when using a machine other than
pc-q35, then the compat property can be safely added to
PC_COMPAT_*;
* If the device can be instantiated when using a machine other than
pc-q35, that means the other machines also need the compat property
to be set.
That means we don't need separate PC_Q35_COMPAT_* macros at all, today.
The hpet.hpet-intcap case is interesting: piix and q35 do have something
that emulates different defaults, but the machine-specific default is
applied _after_ compat_props are applied, by simply checking if the
property is zero (which is the real default on the hpet code).
The hpet.hpet-intcap=0x4 compat property can (should?) be applied to
piix too, because 0x4 was the default on both piix and q35 before the
hpet-intcap property was introduced.
Now, if one day we change the default HPET intcap on one of the PC
machine-types again, we may want to introduce PC_{Q35,I440FX}_COMPAT
macros. But while we don't need that, we can keep the code simple.

Currently SPAPR PHB keeps track of all allocated MSI (here and below
MSI stands for both MSI and MSIX) interrupt because
XICS used to be unable to reuse interrupts. This is a problem for
dynamic MSI reconfiguration which happens when guest reloads a driver
or performs PCI hotplug. Another problem is that the existing
implementation can enable MSI on 32 devices maximum
(SPAPR_MSIX_MAX_DEVS=32) and there is no good reason for that.
This makes use of new XICS ability to reuse interrupts.
This reorganizes MSI information storage in sPAPRPHBState. Instead of
static array of 32 descriptors (one per a PCI function), this patch adds
a GHashTable when @config_addr is a key and (first_irq, num) pair is
a value. GHashTable can dynamically grow and shrink so the initial limit
of 32 devices is gone.
This changes migration stream as @msi_table was a static array while new
@msi_devs is a dynamic hash table. This adds temporary array which is
used for migration, it is populated in "spapr_pci"::pre_save() callback
and expanded into the hash table in post_load() callback. Since
the destination side does not know the number of MSI-enabled devices
in advance and cannot pre-allocate the temporary array to receive
migration state, this makes use of new VMSTATE_STRUCT_VARRAY_ALLOC macro
which allocates the array automatically.
This resets the MSI configuration space when interrupts are released by
the ibm,change-msi RTAS call.
This fixed traces to be more informative.
This changes vmstate_spapr_pci_msi name from "...lsi" to "...msi" which
was incorrect by accident. As the internal representation changed,
thus bumps migration version number.

The existing interrupt allocation scheme in SPAPR assumes that
interrupts are allocated at the start time, continously and the config
will not change. However, there are cases when this is not going to work
such as:
1. migration - we will have to have an ability to choose interrupt
numbers for devices in the command line and this will create gaps in
interrupt space.
2. PCI hotplug - interrupts from unplugged device need to be returned
back to interrupt pool, otherwise we will quickly run out of interrupts.
This replaces a separate lslsi[] array with a byte in the ICSIRQState
struct and defines "LSI" and "MSI" flags. Neither of these flags set
signals that the descriptor is not allocated and not in use.

Change the order of creating devices for New World Mac emulation so

on real hardware and allow clients that hardcode these addresses (e.g.
MorphOS) to find and use them until OpenBIOS is tought to map devices
to specific addresses. (On real hardware the graphics and network
cards are really on separate buses but we don't model that yet.) This

This turns the sPAPR support on and enables VFIO container use
in the kernel.
This extends vfio_connect_container to support VFIO_SPAPR_TCE_IOMMU type
in the host kernel.
This registers a memory listener which sPAPR IOMMU will notify when
executing H_PUT_TCE/etc DMA calls. The listener then will notify the host
kernel about DMA map/unmap operation via VFIO_IOMMU_MAP_DMA/
VFIO_IOMMU_UNMAP_DMA ioctls.
This executes VFIO_IOMMU_ENABLE ioctl to make sure that the IOMMU is free
of mappings and can be exclusively given to the user. At the moment SPAPR
is the only platform requiring this call to be implemented.
Note that the host kernel function implementing VFIO_IOMMU_DISABLE
is called automatically when container's fd is closed so there is
no need to call it explicitly from QEMU. We may need to call
VFIO_IOMMU_DISABLE explicitly in the future for some sort of dynamic
reconfiguration (PCI hotplug or dynamic IOMMU group management).

The patch adds a spapr-pci-vfio-host-bridge device type
which is a PCI Host Bridge with VFIO support. The new device
inherits from the spapr-pci-host-bridge device and adds an "iommu"
property which is an IOMMU id. This ID represents a minimal entity
for which IOMMU isolation can be guaranteed. In SPAPR architecture IOMMU
group is called a Partitionable Endpoint (PE).
Current implementation supports one IOMMU id per QEMU VFIO PHB. Since
SPAPR allows multiple PHB for no extra cost, this does not seem to
be a problem. This limitation may change in the future though.
Example of use:
Configure and Add 3 functions of a multifunctional device to QEMU:
(the NEC PCI USB card is used as an example here):
-device spapr-pci-vfio-host-bridge,id=USB,iommu=4,index=7 \
-device vfio-pci,host=4:0:1.0,addr=1.0,bus=USB,multifunction=true
-device vfio-pci,host=4:0:1.1,addr=1.1,bus=USB
-device vfio-pci,host=4:0:1.2,addr=1.2,bus=USB
where:
* index=7 is a QEMU PHB index (used as source for MMIO/MSI/IO windows
offset);
* iommu=4 is an IOMMU id which can be found in sysfs:
[aik@vpl2 ~]$ cd /sys/bus/pci/devices/0004:00:00.0/
[aik@vpl2 0004:00:00.0]$ ls -l iommu_group

POWER KVM supports an KVM_CAP_SPAPR_TCE capability which allows allocating
TCE tables in the host kernel memory and handle H_PUT_TCE requests
targeted to specific LIOBN (logical bus number) right in the host without
switching to QEMU. At the moment this is used for emulated devices only
and the handler only puts TCE to the table. If the in-kernel H_PUT_TCE
handler finds a LIOBN and corresponding table, it will put a TCE to
the table and complete hypercall execution. The user space will not be
notified.
Upcoming VFIO support is going to use the same sPAPRTCETable device class
so KVM_CAP_SPAPR_TCE is going to be used as well. That means that TCE
tables for VFIO are going to be allocated in the host as well.
However VFIO operates with real IOMMU tables and simple copying of
a TCE to the real hardware TCE table will not work as guest physical
to host physical address translation is requited.
So until the host kernel gets VFIO support for H_PUT_TCE, we better not
to register VFIO's TCE in the host.
This adds a place holder for KVM_CAP_SPAPR_TCE_VFIO capability. It is not
in upstream yet and being discussed so now it is always false which means
that in-kernel VFIO acceleration is not supported.
This adds a bool @vfio_accel flag to the sPAPRTCETable device telling
that sPAPRTCETable should not try allocating TCE table in the host kernel
for VFIO. The flag is false now as at the moment there is no VFIO.
This adds an vfio_accel parameter to spapr_tce_new_table(), the semantic
is the same. Since there is only emulated PCI and VIO now, the flag is set
to false. Upcoming VFIO support will set it to true.
This is a preparation patch so no change in behaviour is expected

At the moment spapr_rtas_register() allocates a new token number for every
new RTAS callback so numbers are not fixed and depend on the number of
supported RTAS handlers and the exact order of spapr_rtas_register() calls.
These tokens are copied into the device tree and remain the same during
the guest lifetime.
When we start another guest to receive a migration, it calls
spapr_rtas_register() as well. If the number of RTAS handlers or their
order is different in QEMU on source and destination sides, the "/rtas"
node in the device tree will differ. Since migration overwrites the device
tree (as it overwrites the entire RAM), the actual RTAS config on
the destination side gets broken.
This defines global contant values for every RTAS token which QEMU
is using today.
This changes spapr_rtas_register() to accept a token number instead of
allocating one. This changes all users of spapr_rtas_register().
This changes XICS-KVM not to cache tokens registered with KVM as they
constant now.
This makes TOKEN_BASE global as RTAS_XXX use TOKEN_BASE as
a base. TOKEN_MAX is moved and renamed too and its value is changed
to the last token + 1. Boundary checks for token values are adjusted.
This reserves token numbers for "os-term" handlers and PCI hotplug
which we are working on.

This is a pc & q35 only machine opt.
If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.
For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.

The only side-effect was that the hpet compat property (inherited from

Without this patch, pc-q35-1.4 inicorrectly initializes hpet-intcap to

Using mii-tool (on F20-live), the following output is produced:
SIOCGMIIREG on ens3 failed: Input/output error
ens3: no autonegotiation, 1000baseT-FD flow-control, link ok
The first line (SIOCGMIIREG error) is due to mii-tool's inability
to read the PHY auto-negotiation expansion register.
On the second line, "no autonegotiation" is wrong, and caused by
the absence of a flag in the link partner ability register which
would indicate that our link partner has acked us. This flag is
listed as "reserved" in the Intel e1000 manual, but mii-tool uses
it as LPA_LPACK from /usr/include/linux/mii.h.
This patch adds read access to PHY_AUTONEG_EXP and defines the
link partner ack flag, allowing mii-tool to generate output as
normally expected:

When the patch was posted that became 5c21ce7 (qdev: Realize buses
on device realization, 2014-03-12), it included recursive realization
and unrealization of devices when the bus's "realized" property
was toggled.
However, due to the same old worries about recursive realization
and prerequisites not being realized yet, those hunks were dropped when
committing the patch. Unfortunately, this causes a use-after-free bug
(easily reproduced by a PCI hot-unplug action).
Before the patch, device_unparent behaved as follows:
for each child bus
unparent bus ----------------------------.
| for each child device |
| unparent device ---------------. |
| | unrealize device | |
| | call dc->unparent | |
| '------------------------------- |
'----------------------------------------'
unrealize device
After the patch, it behaves as follows instead:
unrealize device --------------------.
| for each child bus |
| unrealize bus (A) |
'------------------------------------'
for each child bus
unparent bus ----------------------.
| for each child device |
| unrealize device (B) |
| call dc->unparent |
'----------------------------------'
At the step marked (B) the device might use data from the bus that is
not available anymore due to step (A).
To fix this, we need to unrealize devices before step (A). To sidestep
concerns about recursive realization, only do recursive unrealization
and leave the "value && !bus->realized" case as it is.
The resulting flow is:
for each child bus
unrealize bus ---------------------.
| for each child device |
| unrealize device (B) |
| call bc->unrealize (A) |
'----------------------------------'
unrealize device
for each child bus
unparent bus ----------------------.
| for each child device |
| unparent device |
'----------------------------------'
where everything is "powered down" before it is unassembled.

The initialization takes a chardev backed by a unix domain socket.
It should implement qemu_fe_set_msgfds in order to be able to pass
file descriptors to the remote process.
Each ioctl request of vhost-kernel has a vhost-user message equivalent,
which is sent over the control socket.
The general approach is to copy the data from the supplied argument
pointer to a designated field in the message. If a file descriptor is
to be passed it will be placed in the fds array for inclusion in
the sendmsg control header.
VHOST_SET_MEM_TABLE ignores the supplied vhost_memory structure and scans
the global ram_list for ram blocks with a valid fd field set. This would
be set when the '-object memory-file' option with share=on property is used.

It's hard to track all mac addresses and their configurations (e.g
vlan or ipv6) in qemu. Without this information, it's impossible to
build proper garp packet after migration. The only possible solution
to this is let guest (who knows all configurations) to do this.
So, this patch introduces a new readonly config status bit of virtio-net,
VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce
presence of its link through config update interrupt.When guest has
done the announcement, it should ack the notification through
VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new
feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by
Linux guest).
During load, a counter of announcing rounds is set so that after the vm is
running it can trigger rounds of config interrupts to notify the guest to build
and send the correct garps.

Each hotplug-able memory slot is a PCDIMMDevice.
A hot-add operation for a memory device:
- creates a new PCDIMMDevice and makes hotplug controller to map it into
guest address space
Hotplug operations are done through normal device_add commands.
For migration case, all hotplugged memory devices on source should be
specified on target's command line using '-device' option with
properties set to the same values as on source.
To simplify review, patch introduces only PCDIMMDevice QOM skeleton that
will be extended by following patches to implement actual memory hotplug

The MIPS CPU timer (CP0 Count/Compare registers & QEMU timer) is
reset at machine initialisation, including starting the timeout. Both
registers however are placed before mvp in CPUMIPSState so they will
both be zeroed on reset by the memset in mips_cpu_reset() including soon
after init. This doesn't take into account that the timer may be
running, in which case env->CP0_Count will represent the delta against
the VM clock and the timeout will need updating.
At init time (cpu_mips_clock_init()), lets only create the timer.
Setting Count = 1 and starting the timer (cpu_mips_store_count()) can be
done at reset time from cpu_state_reset(), which is after the memset.
There is also no need to set CP0_Compare = 0 as that is already handled
by the memset.
Note that a reset occurs from mips_cpu_realizefn() which is before the
machine init callback has had a chance to set up the CPU interrupts and
the CPU timer, so env->timer will be NULL. This case is handled
explicitly in cpu_mips_store_count(), treating the timer as disabled
(which will also be the right thing to do when KVM support is added).

Hotplug of multiple disks fails due to MSI vector quota check.
Number of MSI vectors default to 8 allowing only 4 devices.
This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback
to INTX.
One way to workaround the issue is to increase total MSIs,
so that MSI quota check allows us to hotplug multiple disks.
This sets the quota to the maximum number of interupts XICS has
which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c
to xics.h for wider visibility.

normal sPAPR one. Expose the ePAPR /hypervisor node and properties to the
guest so it can use it.
This enables magic page sharing on PR KVM with -M pseries.
However we had a few nasty bugs in the magic page implementation on vcpus
newer than 970 (p7, p8) that KVM now has workarounds for. It indicates that
it does have these workarounds through the PPC_FIXUP_HCALL capability.
To not expose broken guest kernels to issues on host kernels that don't
have the fixups in place, we don't expose working hypercall instructions
when the fixups are not available so that the guest can never active the
magic page.

Modern Linux kernels support last POWERPC CPUs so when a kernel boots,
in most cases it can find a matching cpu_spec in the kernel's cpu_specs
list. However if the kernel is quite old, it may be missing a definition
of the actual CPU. To provide an ability for old kernels to work on modern
hardware, a Processor Compatibility Mode has been introduced
by the PowerISA specification.
>From the hardware prospective, it is supported by the Processor
Compatibility Register (PCR) which is defined in PowerISA. The register
enables one of the compatibility modes (2.05/2.06/2.07).
Since PCR is a hypervisor privileged register and cannot be
directly accessed from the guest, the mode selection is done via
ibm,client-architecture-support (CAS) RTAS call using which the guest
specifies what "raw" and "architected" CPU versions it supports.
QEMU works out the best match, changes a "cpu-version" property of
every CPU and notifies the guest about the change by setting these
properties in the buffer passed as a response on a custom H_CAS hypercall.
This implements ibm,client-architecture-support parameters parsing
(now only for PVRs) and cooks the device tree diff with new values for
"cpu-version", "ibm,ppc-interrupt-server#s" and
"ibm,ppc-interrupt-server#s" properties.

This puts a limit to the number of threads per core based on the current
compatibility mode. Although PowerISA specs do not specify the maximum
threads per core number, the linux guest still expects that
PowerISA2.05-compatible CPU supports only 2 threads per core as this
is what POWER6 (2.05 compliant CPU) implements, the same is for
POWER7 (2.06, 4 threads) and POWER8 (2.07, 8 threads).
This calls spapr_fixup_cpu_smt_dt() with the maximum allowed number of
threads which affects ibm,ppc-interrupt-server#s and
ibm,ppc-interrupt-gserver#s properties.
The number of CPU nodesremains unchanged.

In PPC code we usually use the "cs" name for a CPUState* variables

use same rules as spapr_create_fdt_skel() does.
This adds missing nodes creation if they do not already exist in
the current device tree, this is going to be used from
the client-architecture-support handler.

The PAPR+ specification defines a ibm,client-architecture-support (CAS)
RTAS call which purpose is to provide a negotiation mechanism for
the guest and the hypervisor to work out the best compatibility parameters.
During the negotiation process, the guest provides an array of various
options and capabilities which it supports, the hypervisor adjusts
the device tree and (optionally) reboots the guest.
At the moment the Linux guest calls CAS method at early boot so SLOF
gets called. SLOF allocates a memory buffer for the device tree changes
and calls a custom KVMPPC_H_CAS hypercall. QEMU parses the options,
composes a diff for the device tree, copies it to the buffer provided
by SLOF and returns to SLOF. SLOF updates the device tree and returns
control to the guest kernel. Only then the Linux guest parses the device
tree so it is possible to avoid unnecessary reboot in most cases.
The device tree diff is a header with an update format version
(defined as 1 in this patch) followed by a device tree with the properties
which require update.
If QEMU detects that it has to reboot the guest, it silently does so
as the guest expects reboot to happen because this is usual pHyp firmware
behavior.
This defines custom KVMPPC_H_CAS hypercall. The current SLOF already
has support for it.
This implements stub which returns very basic tree (root node,
no properties) to the guest.
As the return buffer does not contain any change, no change in behavior is
expected.

This adds basic support for the "compat" CPU option. By specifying
the compat property, the user can manually switch guest CPU mode from
"raw" to "architected".
This defines feature disable bits which are not used yet as, for example,
PowerISA 2.07 says if 2.06 mode is selected, the TM bit does not matter -
transactional memory (TM) will be disabled because 2.06 does not define
it at all. The same is true for VSX and 2.05 mode. So just setting a mode
must be ok.
This does not change the existing behavior as the actual compatibility
mode support is coming in next patches.

When we trigger a system reset, the in-kernel openpic controller should also

Signed-off-by: Alexander Graf <agraf@suse.de>
The openpic emulation code maintains an allowable-CPU's bitmap
("destmask") for each IRQ source which is calculated from the IDR
register value whenever the guest OS writes to it. However, if the
guest OS relies on the system to set the IDR register to a default
value at reset, and does not write IDR, then destmask does not get
updated, and interrupts do not get propagated to the guest.
Additionally, if an IRQ source is marked as critical, the source's
internal "output" and "nomask" fields are not correctly reset when the
PIC is reset.
Fix both these issues by calling write_IRQreg_idr from within
openpic_reset, instead of simply setting the IDR register to the
specified idr_reset value.

This allows guests to have a different timebase origin from the host.
This is needed for migration, where a guest can migrate from one host
to another and the two hosts might have a different timebase origin.
However, the timebase seen by the guest must not go backwards, and
should go forwards only by a small amount corresponding to the time
taken for the migration.
This is only supported for recent POWER hardware which has the TBU40
(timebase upper 40 bits) register. That includes POWER6, 7, 8 but not
970.
This adds kvm_access_one_reg() to access a special register which is not

Almost all platforms QEMU emulates have some sort of firmware they can load
to expose a guest environment that closely resembles the way it would look
like on real hardware.
This patch introduces such a firmware on our e500 platforms. U-boot is the
default firmware for most of these systems and as such our preferred choice.
For backwards compatibility reasons (and speed and simplicity) we skip u-boot
when you use -kernel and don't pass in -bios. For all other combinations like
-kernel and -bios or no -kernel you get u-boot as firmware.
This allows you to modify the boot environment, execute a networked boot through
the e1000 emulation and execute u-boot payloads.

At the moment XICS does not support interrupts reuse so sPAPR PHB
implements this. sPAPRPHBState holds array of 32 spapr_pci_msi to
describe PCI config address, first MSI and number of MSIs. Once
allocated for a device, QEMU tries reusing this config until the number
of MSIs changes.
Existing SPAPR guests call ibm,change-msi in a loop until the handler
returns the requested number of vectors.
Recently introduced check for the maximum number of MSI/MSIX vectors
supported by a device only works for a device which is new for PHB's
MSI cache. If it is already there, the check is not performed which
leads to new IRQ block allocation. This happens during PCI hotplug
even when the user hot plug the same device which he just hot unplugged.

the existing ibm,change-msi handler returns 4. But before it returns,
it calls msix_set_message() in a loop and corrupts memory behind
the end of msix_table.

Right now to run firmware inside the QEMU VExpress model requires
padding out the firmware image to the size of the virtual flash and
passing it in via the -pflash argument. If the firmware image is passed
without padding, then QEMU will fail. Also, when passed as a -pflash
argument, QEMU treats the file as persistent storage and will modify the
file.
The -bios flag provides the semantics that we want for providing a
firmware image. This patch maps the contents of the -bios file into the
address space at the boot flash location.
Tested with the vexpress-a15 model and the Tianocore port.

Currently, e1000 support is based on the manual for the 8254xx
model series. 82573x models are documented in a separate manual
(see http://www.intel.com/content/dam/www/public/us/en/documents/manuals/pcie-gbe-controllers-open-source-manual.pdf)
and the 82573L device ID no longer works correctly on either Linux

This patch removes stale code claiming to support 82573L, cleaning
up the code base for the remaining 8254xx model series.

The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.
Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.

We can pick the usb port speed in generic code, by looking at the port

usb_desc_attach as it isn't needed any more.
This way we can set the device speed before calling port->ops->attach,
which fixes some xhci hotplug issues.

This patch uses the new IOMMU notifiers to allow VFIO pass through devices
to work with guest side IOMMUs, as long as the host-side VFIO iommu has
sufficient capability and granularity to match the guest side. This works
by tracking all map and unmap operations on the guest IOMMU using the
notifiers, and mirroring them into VFIO.
There are a number of FIXMEs, and the scheme involves rather more notifier
structures than I'd like, but it should make for a reasonable proof of
concept.

So far, VFIO has a notion of different logical DMA address spaces, but
only ever uses one (system memory). This patch extends this, creating
new VFIOAddressSpace objects as necessary, according to the AddressSpace
reported by the PCI subsystem for this device's DMAs.
This isn't enough yet to support guest side IOMMUs with VFIO, but it does
mean we could now support VFIO devices on, for example, a guest side PCI
host bridge which maps system memory at somewhere other than 0 in PCI
space.

The only model so far supported for VFIO passthrough devices is the model
usually used on x86, where all of the guest's RAM is mapped into the
(host) IOMMU and there is no IOMMU visible in the guest.
This patch begins to relax this model, introducing the notion of a
VFIOAddressSpace. This represents a logical DMA address space which will
be visible to one or more VFIO devices by appropriate mapping in the (host)
IOMMU. Thus the currently global list of containers becomes local to
a VFIOAddressSpace, and we verify that we don't attempt to add a VFIO
group to multiple address spaces.
For now, only one VFIOAddressSpace is created and used, corresponding to
main system memory, that will change in future patches.

This device is ridiculous. It has two MMIO BARs, BAR4 and BAR2. BAR4
hosts the MSI-X table, so oviously it would be too easy to access it
directly, instead it creates a window register in BAR2 that, among
other things, provides access to the MSI-X table. This means MSI-X
doesn't work in the guest because the driver actually manages to
program the physical table. When interrupt remapping is present, the
device MSI will be blocked. The Linux driver doesn't make use of this
window, so apparently it's not required to make use of MSI-X. This
quirk makes the device work with the Windows driver that does use this
window for MSI-X, but I certainly cannot recommend this device for
assignment (the Windows 7 driver also constantly pokes PCI config
space).

To get it out of the default GPIO list. This allows child devices to
use the un-named GPIO namespace without having to be SSI aware. That
is, there is no more need for machines to know about the obscure
policy where GPIO 0 is the SSI chip-select and GPIO 1..N are the
concrete class GPIOs (defined locally as 0..N-1).
This is most notable in stellaris, which uses a device which has both
SSI and concrete level GPIOs.

This drops BlockDriverState.in_use with op_blockers:
- Call bdrv_op_block_all in place of bdrv_set_in_use(bs, 1).
- Call bdrv_op_unblock_all in place of bdrv_set_in_use(bs, 0).
- Check bdrv_op_is_blocked() in place of bdrv_in_use(bs).
The specific types are used, e.g. in place of starting block backup,
bdrv_op_is_blocked(bs, BLOCK_OP_TYPE_BACKUP, ...).
There is one exception in block_job_create, where
bdrv_op_blocker_is_empty() is used, because we don't know the operation
type here. This doesn't matter because in a few commits away we will drop
the check and move it to callers that _do_ know the type.
- Check bdrv_op_blocker_is_empty() in place of assert(!bs->in_use).
Note: there is only bdrv_op_block_all and bdrv_op_unblock_all callers at
this moment. So although the checks are specific to op types, this
changes can still be seen as identical logic with previously with
in_use. The difference is error message are improved because of blocker
error info.

When we migrate we ask the kernel about its current belief on what the guest
time would be. However, I've seen cases where the kvmclock guest structure
indicates a time more recent than the kvm returned time.
To make sure we never go backwards, calculate what the guest would have seen
as time at the point of migration and use that value instead of the kernel
returned one when it's more recent. This bases the view of the kvmclock
after migration on the same foundation in host as well as guest.

According to the PS/2 Mouse/Keyboard Protocol, the keyboard outupt buffer size
is 16 bytes. And the PS2_QUEUE_SIZE 256 was introduced in Qemu from the very
beginning.
When I started a redhat5.6 32bit guest, meanwhile tapped the keyboard as quickly as
possible, the screen would show me "i8042.c: No controller found". As a result,
I couldn't use the keyboard in the VNC client.
Previous discussion about the issue in maillist:
http://thread.gmane.org/gmane.comp.emulators.qemu/43294/focus=47180
This patch has been tested on redhat5.6 32-bit/suse11sp3 64-bit guests.
More easy meathod to reproduce:
1.boot a guest with libvirt.
2.connect to VNC client.
3.as you see the BIOS, bootloader, Linux booting, run the follow simply shell script:
for((i=0;i<10000000;i++)) do virsh send-key redhat5.6 KEY_A; done
Actual results:
dmesg show "i8042.c: No controller found." And the keyboard is out of work.

We commonly use the error API like this:
err = NULL;
foo(..., &err);
if (err) {
goto out;
}
bar(..., &err);
Every error source is checked separately. The second function is only
called when the first one succeeds. Both functions are free to pass
their argument to error_set(). Because error_set() asserts no error
has been set, this effectively means they must not be called with an
error set.
The qapi-generated code uses the error API differently:
// *errp was initialized to NULL somewhere up the call chain
frob(..., errp);
gnat(..., errp);
Errors accumulate in *errp: first error wins, subsequent errors get
dropped. To make this work, the second function does nothing when
called with an error set. Requires non-null errp, or else the second
function can't see the first one fail.
This usage has also bled into visitor tests, and two device model
object property getters rtc_get_date() and balloon_stats_get_all().
With the "accumulate" technique, you need fewer error checks in
callers, and buy that with an error check in every callee. Can be
nice.
However, mixing the two techniques is confusing. You can't use the
"accumulate" technique with functions designed for the "check
separately" technique. You can use the "check separately" technique
with functions designed for the "accumulate" technique, but then
error_set() can't catch you setting an error more than once.
Standardize on the "check separately" technique for now, because it's
overwhelmingly prevalent.

Correct post load checks:

2. When state is DATA, passing index > len
will cause memcpy with negative length,
resulting in heap overflow

Packet transmission for the stellaris ethernet controller can be triggered
in one of two ways:
* by setting a threshold value in the THR register; when the FIFO
fill level reaches the threshold, the h/w starts transmitting.
Software has to finish filling the FIFO before the transmit
process completes to avoid a (silent) underrun
* by software writing to the TR register to explicitly trigger
transmission
Since QEMU transmits packets instantaneously (from the guest's
point of view), implement "transmit based on threshold" with
our existing mechanism of "transmit as soon as we have the whole
packet", with the additional wrinkle that we don't transmit if
the packet size is below the specified threshold, and implement
"transmit by specific request" properly.

The PADEN bit in the transmit control register enables padding of short

meant we were adjusting tx_fifo_len rather than tx_frame_len, so the
padding didn't actually happen. Fix this bug.

The current tx_fifo code has a corner case where the guest can overrun
the fifo buffer: if automatic CRCs are disabled we allow the guest to write
the CRC word even if there isn't actually space for it in the FIFO.
The datasheet is unclear about exactly how the hardware deals with this
situation; the most plausible answer seems to be that the CRC word is
just lost.
Implement this fix by separating the "can we stuff another word in the
FIFO" logic from the "should we transmit the packet now" check. This
also moves us closer to the real hardware, which has a number of ways
it can be configured to trigger sending the packet, some of which we
don't implement.

The PIIX datasheet says that "before another INIT pulse can be
generated via [port 92h], [bit 0] must be written back to a
zero.
This bug is masked right now because a full reset will clear the
value of port 92h. But once we implement soft reset correctly,
the next attempt to enable the A20 line by setting bit 1 (and
leaving the others untouched) will cause another reset.

Use the cflags only where really used (for two mentioned files), and
libs only where needed.
While at it, rename variables to better reflect reality: libcacard_*
is really nss_*.
This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs

Current css code saves the operation request block (orb) in the
subchannel structure for later consumption by the start function
handler. This might make sense for asynchronous execution of the
start function (which qemu doesn't support), but not in our case;
it would even be wrong since orb contains a reference to a local
variable in the base ssch handler.
Let's just pass the orb through the start function call chain for
ssch; for rsch, we can pass NULL as the backend function does not
use any information passed via the orb there.

hw/scsi/scsi-bus.c invokes load_request.
virtio_scsi_load_request does:
qemu_get_buffer(f, (unsigned char *)&req->elem, sizeof(req->elem));
this probably can make elem invalid, for example,
make in_num or out_num huge, then:
virtio_scsi_parse_req(s, vs->cmd_vqs[n], req);
will do:
if (req->elem.out_num > 1) {
qemu_sgl_init_external(req, &req->elem.out_sg[1],
&req->elem.out_addr[1],
req->elem.out_num - 1);
} else {
qemu_sgl_init_external(req, &req->elem.in_sg[1],
&req->elem.in_addr[1],
req->elem.in_num - 1);
}
and this will access out of array bounds.
Note: this adds security checks within assert calls since
SCSIBusInfo's load_request cannot fail.

It also requires proper cleanup because some of the memory inside is allocated

Number of vqs is max_queues, so if we get invalid input here,

Replace existing smbios_check_collision() functionality with
a pair of bitmaps: have_binfile_bitmap and have_fields_bitmap.
Bits corresponding to each smbios type are set by smbios_entry_add(),
which also uses the bitmaps to ensure that binary blobs and field
values are never accepted for the same type.
These bitmaps will also be used in the future to decide whether
or not to build a full table for a given smbios type.

For an AArch64 CPU which supports 64K pages, having the GIC
register banks at 4K offsets is potentially awkward. Move
them out to being at 64K offsets. (This is harmless for
AArch32 CPUs and for AArch64 CPUs with 4K pages, so it is simpler
to use the same offsets everywhere than to try to use 64K offsets
only for AArch64 host CPUs.)

Rather than having the virt machine model create an a15mpcore_priv
device regardless of the actual CPU type in order to instantiate the GIC,
move to having the machine model create the GIC directly. This
corresponds to a system which uses a standalone GIC (eg the GIC-400)
rather than the one built in to the CPU core.
The primary motivation for this is to support the Cortex-A57,
which for a KVM configuration will use a GICv2, which is not
built into the CPU.

This patch adds an errp parameter to bdrv_new() and updates all its
callers. The next patches will make use of this in order to check for
duplicate IDs. Most of the callers know that their ID is fine, so they
can simply assert that there is no error.
Behaviour doesn't change with this patch yet as bdrv_new() doesn't
actually assign errors to errp.

Near total rewrite of this device model. It is stylistically
obsolete, has numerous coverity fails and is not up to date with latest
Xilinx documentation. Fix.
The registers are flattened into a single array. This greatly simplifies
the MMIO accessor functions.
We take the oppurtunity to update the register Macro definitions to
match the latest TRM. Xilinx has de-documented some regs hence there are
some straight deletions. We only do this however in the case or a stock
read-as-written reset-zero register. Non-zero resets are always
preserved. New register definitions are added as needed.
This all comes with a VMSD version break as the union layout from before
was a bit strange and we are better off without it.
