Alex Williamson 47cbe50cc8 vfio-pci: Enable device request notification support
Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user.  When signaled, QEMU
will by default attmempt to hot-unplug the device.  This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned.  Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature.  Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

Samuel Pitoiset 6ee47c9008 vfio: allow to disable MMAP per device with -x-mmap=off option
Disabling MMAP support uses the slower read/write accesses but allows to
trace all MMIO accesses, which is not good for performance, but very
useful for reverse engineering PCI drivers. This option allows to
disable MMAP per device without a compile-time change.

Max Reitz f6758f7d6b virtio-scsi: Allocate op blocker reason before blocking
s->blocker is really only used in hw/scsi/virtio-scsi.c; the only places
where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is
allocated and when it is freed. That does not make a whole lot of sense
(and is actually wrong because this leads to s->blocker potentially
being NULL when blk_op_block_all() is called in virtio-scsi.c), so move
the allocation and destruction of s->blocker to the device realization
and unrealization in virtio-scsi.c, respectively.

Case in point:

$ echo -e 'eject drv\nquit' | \
    x86_64-softmmu/qemu-system-x86_64 \
        -monitor stdio -machine accel=qtest -display none \
        -object iothread,id=thr -device virtio-scsi-pci,iothread=thr \
        -drive if=none,file=test.qcow2,format=qcow2,id=drv \
        -device scsi-cd,drive=drv

Without this patch:

(qemu) eject drv
[1]    10102 done
       10103 segmentation fault (core dumped)

With this patch:

(qemu) eject drv
Device 'drv' is busy: block device is in use by data plane
(qemu) quit

Currently the ivshmem device is built whenever both PCI and KVM support are

customization of whether to include it.  It's enabled by default in the
same circumstances as now - when both PCI and KVM are available.

David Gibson 2296594257 Create specific config option for "platform-bus"
Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices.  However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.

To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

David Gibson 4681867544 Add specific config options for PCI-E bridges
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.

While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.

Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.

(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

Paolo Bonzini 2264750483 scsi: give device a parent before setting properties
This mimics what is done in qdev_device_add, and lets the device be
freed in case something goes wrong.  Otherwise, object_unparent returns
immediately without freeing the device, which is on the other hand left
in the parent bus's list of children.

scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is
destroyed as well with object_unparent.  But the lingering device that
was not removed in scsi_bus_legacy_add_drive cannot be removed now either,
and bus_unparent gets stuck in an infinite loop trying to empty the list
of children.

The right fix of course would be to assert in bus_add_child that the
device already has a bus, and remove the "safety net" that adds the
drive to the QOM tree in device_set_realized.  I am not yet sure whether
that would entail changing all callers to qdev_create (as well as
isa_create and usb_create and the corresponding _try_create versions).

Markus Armbruster f43e47dbf6 QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix use
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().

Most of its users assume the function can't fail.  Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.

Just two users remain, in util/qemu-config.c.  Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

Peter Maydell 11d39a1310 Features for s390x/kvm
1. guest reIPL changes (Fan Zhang)
 Implements subcode 5 and 6 of diag 0x308. This allows to use
 /sys/firmware/[re]ipl/ccw/* and the chreipl and lsreipl tools in
 Linux. In addition to the normal "change the disk" this also
 allows to switch from booting an external kernel into rebooting
 from a disk.
 
 2. Memory page table walking (Thomas Huth)
 Fix several page table walking functions, used in several places
 like gdb server and instruction handling. Also use these functions
 in several I/O related functions.

etsec_create() is a helper to create and realize the eTSEC.  It's
currently unused.  Similar helpers for other NICs use
qdev_init_nofail().  Match that.

looks like it could fail, but since isa_ide_realizefn() can't fail, it
actually can't.  Replace its qdev_init() by qdev_init_nofail() to make

Markus Armbruster bd8b92d5c8 usb: Suppress bogus error when automatic usb-hub creation fails
USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left.  Creating devices in realize
methods is questionable, but works.

If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored.  We then create the actual device using
the last port, which may well succeed.

Example:

    $ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
    QEMU 2.2.50 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    [Repeat 36 times]
    (qemu) info usb
      Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
      Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
      Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
    [More mice and hubs omitted...]
      Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
    (qemu) device_add usb-mouse
    usb hub chain too deep
    Failed to initialize USB device 'usb-hub'
    (qemu) info usb
    [...]
      Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
      Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse

Despite the "Failed" message, the command actually succeeded.

In QMP, it's worse.  When adding the 37th mouse via QMP, the command
fails with

    {"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}

Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr.  Despite the command failure, the device was created.  This
is wrong.

Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

Markus Armbruster 3bc36a401e usb: Improve -usbdevice error reporting a bit
Most LegacyUSBFactory usbdevice_init() methods realize with
qdev_init_nofail(), even though their caller usbdevice_create() can
handle failure.  Okay if it really can't fail (I didn't check), but
somewhat brittle.

usb_msd_init() and usb_bt_init() call qdev_init().  The latter
additionally reports an error when qdev_init() fails.

Realization failure produces multiple error reports: a specific one
from qdev_init(), and generic ones from usb_bt_init(),
usb_create_simple(), usbdevice_create() and usb_parse().

Remove realization from the usbdevice_init() methods.  Realize in
usbdevice_create(), and produce exactly one error message there.  You
still get another one from usb_parse().

Markus Armbruster 1677f4c66c monitor: Clean up around monitor_handle_fd_param()
monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them.  qerror_report_err() is inappropriate in
many contexts.  monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use.  Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.

Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report().  Turns out that's everywhere.

While there, rename monitor_handle_fd_param2() to monitor_fd_param().

Markus Armbruster 248337e178 vhost-scsi: Improve error reporting for invalid vhostfd
We get two error messages: one from monitor_handle_fd_param2(), and
another one from vhost_scsi_realize().  The second one gets suppressed
in QMP context.

That's because monitor_handle_fd_param() calls qerror_report_err().
Calling qerror_report_err() is always inappropriate in realize
methods, because it doesn't return the Error object.  It either
reports the error to stderr or the human monitor, or it stores it in
the QMP monitor, where it makes the QMP command fail even when the
realize method ignores the error and succeeds.  Fortunately,
vhost_scsi_realize() doesn't do that.

Fix by switching to monitor_handle_fd_param2().
