Current ppc_set_compat() returns -1 for errors, and also (unconditionally)
reports an error message. The caller in h_client_architecture_support()
may then report it again using an outdated fprintf().
Clean this up by using the modern error reporting mechanisms. Also add
strerror(errno) to the error message.

rtas_st_buffer() appears in spapr.h as though it were a widely used helper,
but in fact it is only used for saving data in a format used by
rtas_ibm_get_system_parameter(). This changes it to a local helper more
specifically for that function.
While we're there fix a couple of small defects in
rtas_ibm_get_system_parameter:
- For the string value SPLPAR_CHARACTERISTICS, it wasn't including the
terminating \0 in the length which it should according to LoPAPR
7.3.16.1
- It now checks that the supplied buffer has at least enough space for
the length of the returned data, and returns an error if it does not.

Until the previous patch this relied on xc_fd(), which was only
implemented for Xen 4.0 and earlier.
Given this wasn't working since Xen 4.0 I have marked this as disabled
by default.
Removing this support drops the use of a bunch of symbols from
libxenctrl, specifically:
- xc_domain_create
- xc_domain_destroy
- xc_domain_getinfo
- xc_domain_max_vcpus
- xc_domain_setmaxmem
- xc_domain_unpause
- xc_evtchn_alloc_unbound
- xc_linux_build
This is another step towards only using Xen libraries which provide a
stable inteface.

In Xen 4.7 we are refactoring parts libxenctrl into a number of
separate libraries which will provide backward and forward API and ABI
compatiblity.
One such library will be libxenforeignmemory which provides access to
privileged foreign mappings and which will provide an interface
equivalent to xc_map_foreign_{pages,bulk}.
The new xenforeignmemory_map() function behaves like
xc_map_foreign_pages() when the err argument is NULL and like
xc_map_foreign_bulk() when err is non-NULL, which maps into the shim
here onto checking err == NULL and calling the appropriate old
function.
Note that xenforeignmemory_map() takes the number of pages before the
arrays themselves, in order to support potentially future use of
variable-length-arrays in the prototype (in the future, when Xen's
baseline toolchain requirements are new enough to ensure VLAs are
supported).
In preparation for adding support for libxenforeignmemory add support
to the <=4.0 and <=4.6 compat code in xen_common.h to allow us to
switch to using the new API. These shims will disappear for versions
of Xen which include libxenforeignmemory.
Since libxenforeignmemory will have its own handle type but for <= 4.6
the functionality is provided by using a libxenctrl handle we
introduce a new global xen_fmem alongside the existing xen_xc. In fact
we make xen_fmem a pointer to the existing xen_xc, which then works
correctly with both <=4.0 (xc handle is an int) and <=4.6 (xc handle
is a pointer). In the latter case xen_fmem is actually a double
indirect pointer, but it all falls out in the wash.
Unlike libxenctrl libxenforeignmemory has an explicit unmap function,
rather than just specifying that munmap should be used, so the unmap
paths are updated to use xenforeignmemory_unmap, which is a shim for
munmap on these versions of xen. The mappings in xen-hvm.c do not
appear to be unmapped (which makes sense for a qemu-dm process)
In fb_disconnect this results in a change from simply mmap over the
existing mapping (with an implicit munmap) to expliclty unmapping with
xenforeignmemory_unmap and then mapping the required anonymous memory
in the same hole. I don't think this is a problem since any other
thread which was racily touching this region would already be running
the risk of hitting the mapping halfway through the call. If this is
thought to be a problem then we could consider adding an extra API to
the libxenforeignmemory interface to replace a foreign mapping with
anonymous shared memory, but I'd prefer not to.

One such library will be libxenforeignmemory which provides access to
privileged foreign mappings and which will provide an interface
equivalent to xc_map_foreign_{pages,bulk}.
In preparation for this switch all uses of xc_map_foreign_range to
xc_map_foreign_pages. This is trivial because size was always
XC_PAGE_SIZE so the necessary adjustments are trivial:
* Pass &mfn (an array of length 1) instead of mfn. The function
takes a pointer to const, so there is no possibily of mfn changing
due to this change.
* Pass nr_pages=1 instead of size=XC_PAGE_SIZE
There is one wrinkle in xen_console.c:con_initialise() where
con->ring_ref is an int but can in some code paths (when !xendev->dev)
be treated as an mfn. I think this is an existing latent truncation
hazard on platforms where xen_pfn_t is 64-bit and int is 32-bit (e.g.
amd64, both arm* variants). I'm unsure under what circumstances
xendev->dev can be NULL or if anything elsewhere ensures the value
fits into an int. For now I just use a temporary xen_pfn_t to in
effect upcast the pointer from int* to xen_pfn_t*.
In xenfb.c:common_bind we now explicitly launder the mfn into a
xen_pfn_t, so it has the correct type to be passed to
xc_map_foreign_pages and doesn't provoke warnings on 32-bit x86.

To simplify things for the <= 4.0.0 support we wrap the int fd in a

The 2.88 drive is more suitable as a default because
it can still read 1.44 images correctly, but the reverse
is not true.
Since there exist virtio-win drivers that are shipped on
2.88 floppy images, this patch will allow VMs booted without
a floppy disk inserted to later insert a 2.88MB floppy and
have that work.
This patch has been tested with msdos, freedos, fedora,
windows 8 and windows 10 without issue: if problems do
arise for certain guests being unable to cope with 2.88MB
drives as the default, they are in the minority and can use
type=144 as needed (or insert a proper boot medium and omit
type=144/288 or use type=auto) to obtain different drive types.
As icing, the default will remain auto/144 for any pre-2.6
machine types, hopefully minimizing the impact of this change
in legacy hw to basically zero.

This one is the crazy one.
fd_revalidate currently uses pick_geometry to tell if the diskette
geometry has changed upon an eject/insert event, but it won't allow us
to insert a 1.44MB diskette into a 2.88MB drive. This is inflexible.
The new algorithm applies a new heuristic to guessing disk geometries
that allows us to switch diskette types as long as the physical size
matches before falling back to the old heuristic.
The old one is roughly:
- If the size (sectors) and type matches, choose it.
- Fall back to the first geometry that matched our type.
The new one is:
- If the size (sectors) and type matches, choose it.
- If the size (sectors) and physical size match, choose it.
- Fall back to the first geometry that matched our type.

2.88MB capable drives can accept 1.44MB floppies,
for instance. To rework the pick_geometry function,
we need to know if our current drive can even accept
the type of disks we're considering.
NB: This allows us to distinguish between all of the
"total sectors" collisions between 1.20MB and 1.44MB
diskette types, by using the physical drive size as a
differentiator.

This patch adds a new explicit Floppy Drive Type option. The existing
behavior in QEMU is to automatically guess a drive type based on the
media inserted, or if a diskette is not present, arbitrarily assign one.
This behavior can be described as "auto." This patch adds the option
to pick an explicit behavior: 120, 144, 288 or none. The new "auto"
option is intended to mimic current behavior, while the other types
pick one explicitly.
Set the type given by the CLI during fd_init. If the type remains the
default (auto), we'll attempt to scan an inserted diskette if present
to determine a type. If auto is selected but no diskette is present,
we fall back to a predetermined default (currently 1.44MB to match
legacy QEMU behavior.)

Change this behavior to be configurable, but leave it defaulted to 1.44.

pick_geometry is a convoluted function that makes it difficult to tell
at a glance what QEMU's current behavior for choosing a floppy drive
type is when it can't quite identify the diskette.
The code iterates over all entries in the candidate geometry table
("fd_formats") and if our specific drive type matches a row in the table,
then either "match" is set to that entry (an exact match) and the loop
exits, or "first_match" will be non-negative (the first such entry that
shares the same drive type), and the loop continues. If our specific
drive type is NONE, then all drive types in the candidate geometry table
are considered. After iteration, if "match" was not set, we fall back to
"first match".
This means that either "match" was set, or we exited the loop without an
exact match, in which case:
- If drive type is NONE, the default is truly fd_formats[0], a 1.44MB
type, because "first_match" will always get set to the first item.
- If drive type is not NONE, pick_geometry's iteration was fussier and
only looked at rows that matched our drive type. However, since all
possible drive types are represented in the table, we still know that
"first match" was set.
- If drive type is not NONE and the fd_formats table lists no options for
our drive type, we choose fd_formats[1], an incomprehensibly bizarre
choice that can never happen anyway.
Correct this: If first_match is -1, it can ONLY mean we didn't edit our
fd_formats table correctly. Throw an assertion instead.

Currently, 'drive' is used both to represent the current diskette
type as well as the current drive type.
This patch adds a 'disk' field that is updated explicitly to match
the type of the disk.
As of this patch, disk and drive are always the same, but forthcoming
patches to change the behavior of pick_geometry will invalidate this
assumption.
disk does not need to be migrated because it is not user-visible state
nor is it currently used for any calculations. It is purely informative,

This patch enables migrating vcpu's TSC rate. If KVM on the
destination machine supports TSC scaling, guest programs will
observe a consistent TSC rate across the migration.
If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination will
not set vcpu's TSC rate to the migrated value.
If vcpu's TSC rate specified by CPU option 'tsc-freq' on the
destination machine is inconsistent with the migrated TSC rate,
the migration will be aborted.
For backwards compatibility, the migration of vcpu's TSC rate is
disabled on pc-*-2.5 and older machine types.

The PCI spec recommends devices use additional alignment for MSI-X
data structures to allow software to map them to separate processor
pages. One advantage of doing this is that we can emulate those data
structures without a significant performance impact to the operation
of the device. Some devices fail to implement that suggestion and
assigned device performance suffers.
One such case of this is a Mellanox MT27500 series, ConnectX-3 VF,
where the MSI-X vector table and PBA are aligned on separate 4K

clear how much value we get from PBA emulation, but the solution here
is to only lazily enable the emulated PBA when a masked MSI-X vector
fires. We then attempt to more aggresively disable the PBA memory
region any time a vector is unmasked. The expectation is then that
a typical VM will run entirely with PBA emulation disabled, and only
when used is that emulation re-enabled.

For quirks that support the full PCIe extended config space, limit the
quirk to only the size of config space available through vfio. This
allows host systems with broken MMCONFIG regions to still make use of
these quirks without generating bad address faults trying to access
beyond the end of config space exposed through vfio. This may expose
direct access to the mirror of extended config space, only trapping
the sub-range of standard config space, but allowing this makes the
quirk, and thus the device, functional. We expect that only device
specific accesses make use of the mirror, not general extended PCI
capability accesses, so any virtualization in this space is likely
unnecessary anyway, and the device is still IOMMU isolated, so it
should only be able to hurt itself through any bogus configurations
enabled by this space.

Otherwise there is a race where the DEVICE_DELETED event has been sent but
attempts to reuse the ID will fail.
Note that similar races exist for other QemuOpts, which this patch
does not attempt to fix.
For example, if the device is a block device, then unplugging it also
deletes its backend. However, this backend's get deleted in
drive_info_del(), which is only called when properties are
destroyed. Just like device_finalize(), drive_info_del() is called
some time after DEVICE_DELETED is sent. A separate patch series has
been sent to plug this other bug. Character devices also have yet to
be fixed.

Currently the ObjectProperty iterator API works as follows:
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
...
}
object_property_iter_free(iter);
This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.
This patch changes the API to use stack allocation instead:
ObjectPropertyIterator iter;
object_property_iter_init(&iter, obj);
while ((prop = object_property_iter_next(&iter))) {

The qemu-char.c contains two helper methods send_all
and recv_all. These are in fact declared in sockets.h
so ought to have been in util/qemu-sockets.c. For added
fun the impl of recv_all is completely missing on Win32.
Fortunately there is only a single caller of these
methods, the TPM passthrough code, which is only
ever compiled on Linux. With only a single caller
these helpers are not compelling enough to keep so
inline them in the TPM code, avoiding the need to
fix the missing recv_all on Win32.

Hello,
A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
occurs while doing I/O port write operations via hmp interface. In that,
'current_cpu' remains null as it is not called from cpu_exec loop, which
results in the said issue.
Below is a proposed (tested)patch to fix this issue; Does it look okay?

Fam Zheng noticed that the change in commit 36896bf ("scsi: always call
notifier on async cancellation", 2015-12-16) could cause a leak of
the request; scsi_req_cancel_async now calls scsi_req_ref
multiple times for multiple cancellations, but there is only
one call to scsi_req_cancel_complete.
So revert the patch and instead assert that the problematic case (a call
to scsi_req_cancel_async after the aiocb has been completed) cannot
happen.

While UEFI can use libfdt to disable the RTC device node in the DTB that
it passes to the OS, it cannot modify AML. Therefore, we won't generate

The Xilinx ZynqMP SoC and EP108 board supports three memory regions:
- A 2GB region starting at 0
- A 32GB region starting at 32GB
- A 256GB region starting at 768GB
This patch adds support for the first two memory regions, which is
automatically created based on the size specified by the QEMU memory
command line argument.
On hardware the physical memory region is one continuous region, it is then
mapped into the three different regions by the DDRC. As we don't model the
DDRC this is done at startup by QEMU. The board creates the memory region and
then passes that memory region to the SoC. The SoC then maps the memory
regions.

Both error_report_err() and monitor_printf() print to the same
destination when monitor_printf() is used correctly, i.e. within an
HMP monitor. Elsewhere, monitor_printf() does nothing, while
error_report_err() reports to stderr.
Most changed functions are HMP command handlers. These should only
run within an HMP monitor. The one exception is bdrv_password_cb(),
which should also only run within an HMP monitor.
Four command handlers prefix the error message with the command name:
balloon, migrate_set_capability, migrate_set_parameter, migrate.
Pointless, drop.
Unlike monitor_printf(), error_report_err() uses the error whole
instead of just its message obtained with error_get_pretty(). This
avoids suppressing its hint (see commit 50b7b00). Example:
(qemu) device_add ivshmem,id=666
Parameter 'id' expects an identifier
Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
Try "help device_add" for more information
The "Identifiers consist of..." line is new with this patch.

isa_bus_irqs(), isa_create() and isa_try_create() call hw_error() when
passed a null bus. Use of hw_error() has always been questionable,
because these are used only during machine initialization, and
printing CPU registers isn't useful there.
Since the previous commit, passing a null bus is a programming error.
Drop the hw_error() and simply let it crash.

We can have at most one ISA bus. If you try to create another one,
isa_bus_new() complains to stderr and returns null.
isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods. Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.
Machine's init():
* mips_jazz_init(), called from the init() methods of machines
"magnum" and "pica"
* mips_r4k_init(), the init() method of machine "mips"
* pc_init1() called from the init() methods of non-q35 PC machines
* typhoon_init(), called from clipper_init(), the init() method of
machine "clipper"
These callers always create the first ISA bus, hence isa_bus_new()
can't fail. Simply pass &error_abort.
Device's realize():
* i82378_realize(), of PCI device "i82378"
* ich9_lpc_realize(), of PCI device "ICH9-LPC"
* pci_ebus_realize(), of PCI device "ebus"
* piix3_realize(), of PCI device "pci-piix3", abstract parent of
"PIIX3" and "PIIX3-xen"
* piix4_realize(), of PCI device "PIIX4"
* vt82c686b_realize(), of PCI device "VT82C686B"
Propagate the error. Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar. If
we screwed up and created an ISA bus before that call, we now give up
right away. Before, we'd hobble on, and typically die in
isa_bus_irqs(). Similar if someone finds a way to hot-plug one of
these critters.

platform_bus_map_irq() and platform_bus_map_mmio() use hw_error() to
fail. They run in machine_init_done_notifiers, via
platform_bus_init_notify() and link_sysbus_device(). Printing CPU
registers is not helpful there.
Replace hw_error() by error_report(); exit(1). If these are
programming errors, it should be replaced by an assertion instead.
While there, observe that both functions always return 0, and
link_sysbus_device() ignores the return value. Change them to void.

The errors are all device misconfiguration. All callers use
qdev_init_nofail(), so this patch merely converts hw_error() crashes
into &error_abort crashes. Improvement, because now it crashes closer
to where the misconfiguration bug would be, and a few more bad
examples of hw_error() use are gone.

Moreover, these are straightforward configuration or "can get

Currently each of the *_class_options() functions for the pseries-2.1 ..
pseries-2.5 machine types are standalone. This will become harder to
maintain as new versions are added.
This patch restructures them similarly to x86 where each function calls
the one from the next version, then overrides anything necessary for
compatibility with the specific version and older.
The default behaviour - that for the most recent machine are set up in
the base class initializer spapr_machine_class_init(). Previously it had
some things set up to default to older behaviour with the more recent
machines overriding it.

At the moment all the class_init functions and TypeInfo structures for the
various versioned pseries machine types are open-coded. As more versions
are created this is getting increasingly clumsy.
This patch borrows the approach used in PC, using a DEFINE_SPAPR_MACHINE()
macro to construct most of the boilerplate from simpler 'class_options' and
'instance_options' functions.
This patch makes a small semantic change - the versioned machine types are
now registered through machine_init() instead of type_init(). Since the
new way is how PC already did it, I'm assuming that's correct.

hw/ppc/spapr.c has a number of definitions related to the various versioned
machine types ("pseries-2.1" .. "pseries-2.5") it defines. These are
mostly arranged by type of function first, then machine version second, and
it's not consistent about whether it goes in increasing or decreasing
version order.
This rearranges the code to keep all the definitions for a particular
machine version together, and arrange then consistently in order most
recent to least recent.
This brings us closer to matching the way PC does things, and makes later
cleanups easier to follow.
Apart from adding some comments marking each section, this is a pure
mechanical rearrangement with no semantic changes.

The ACPI specification (minimally versions 1.0b through 6.0) define the
FADT.CENTURY field as:
The RTC CMOS RAM index to the century of data value (hundred and
thousand year decimals). If this field contains a zero, then the RTC
centenary feature is not supported. If this field has a non-zero value,
then this field contains an index into RTC RAM space that OSPM can use
to program the centenary field.
The x86 targets generate ACPI payload, emulate an RTC
(CONFIG_MC146818RTC), and that RTC supports the "centenary feature" (see
occurrences of RTC_CENTURY in cmos_ioport_write() and cmos_ioport_read()
in "hw/timer/mc146818rtc.c".)
However, FADT.CENTURY is left at zero currently:
[06Ch 0108 1] RTC Century Index : 00
which -- according to analysis done by Ruiyu Ni at Intel -- should cause
Linux and Windows 8+ to think the RTC centenary feature is unavailable,
and cause Windows 7 to (incorrectly) assume that the offset to use is
constant 0x32. (0x32 happens to be the right value on QEMU, but Windows 7
is wrong to assume anything at all).
Exposing the right nonzero offset in FADT.CENTURY informs Linux and
Windows 8+ about the right capabilities of the hardware, plus it retrofits
our FADT to Windows 7's behavior.

internal. Then, convert it to above [RIGHT] format to write by
console_write_ch(). And as bonus, this reduces to expose curses define
to other parts (removes COLOR_* from console.c).
[Tested the first line is displayed as white on blue back for monitor
in curses console]

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.
This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_suspend(): the function stop the operation and acknowledge
pending interrupts (but doesn't disable it). Later in the function,
the device is moved to OHCI_SUSPEND_STATE, and the driver to
OHCI_RH_SUSPENDED. If between the moment when the interrupt is
acknowledged and the moment when the device is suspended a new
interrupt is raised, it will be never acknowledged because the
driver is now not in OHCI_RH_RUNNING state.

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.
This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
In QEMU this start the SOF timer and QEMU starts to send IRQs. As
the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
the ohci_irq() can be called and the driver never moved to
OHCI_STATE_RUNNING.

- SPA structure, defines the PMEM region info
- MEM DEV structure, it has the @handle which is used to associate specified
ACPI NVDIMM device we will introduce in later patch.
Also we can happily ignored the memory device's interleave, the real
nvdimm hardware access is hidden behind host
- DCR structure, it defines vendor ID used to associate specified vendor
nvdimm driver. Since we only implement PMEM mode this time, Command

The NVDIMM functionality is controlled by the parameter, 'nvdimm', which

Add the basic IPMI types and infrastructure to QEMU. Low-level
interfaces and simulation interfaces will register with this; it's
kind of the go-between to tie them together.

The pxb-pcie is the counterpart of pxb for PCI express machines.
The new device re-uses the pxb code, but appears to the guests
as a different device. The pxb-pcie device does not have an internal
pci-pci bridge and exposes a PCIe root bus instead of a PCI one.

A generic PCI Bus Expander doesn't necessary have a built-in PCI bridge.
Int this case the ACPI will include IO/MEM ranges per device. Try to merge
adjacent resources to reduce the ACPI tables length.

This is needed for a quirk of the Raspberry Pi (bcm2835/6) MMC
controller, where the card insert bit is documented as unimplemented
(always reads zero, doesn't generate interrupts) but is in fact
observed on hardware as set at power on, but is cleared (and remains
clear) on subsequent controller resets.

This deletes a block of code that raised a command index error if a
command returned response data, but the guest did not set the
appropriate bits in the response register to handle such a response. I
cannot find any documentation that suggests the controller should
behave in this way, the error code doesn't make sense (command index
error is defined for the case where the index in a response does not
match that of the issued command), and in at least one case (CMD23
issued by UEFI on Raspberry Pi 2), actual hardware does not do this.

This check was conditionalising SD card operation on the card being
powered by the SDHCI host controller. It is however possible
(particularly in embedded systems) for the power control of the SD card
to be managed outside of SDHCI. This can be as trivial as hard-wiring
the SD slot VCC to a constant power-rail.
This means the guest SDHCI can validly opt-out of the SDHCI power
control feature while still using the card. So delete this check to
allow operation of the card with SDHCI power control.
This is needed for at least Xilinx Zynq and Raspberry Pi, and
also makes Freescale i.MX25 work for me. The digilent Zybo board
has a public schematic which shows SD VCC hardwiring:
