19380b1bf5 s390: Drop set_bit usage in virtio_ccw.
set_bit on indicators doesn't go well on 32 bit targets:

note: expected 'long unsigned int *' but argument is of type 'uint64_t *'

Switch to bit shifts instead.

virtio-s390 devices are not being reset when their bus is.  To fix
this, add a reset method that forwards to virtio_reset.  This is

8d5ce2e564 prep_pci: Convert to QOM realizefn
SysBusDeviceClass' initfn merely calls SysBusDeviceClass::init, so we
can already hook up our own realizefn overwriting this behavior.

A symmetric unrealizefn is not necessary, knowing that the child's

recursive realization at DeviceState-level is implemented.

This keeps compatibility on machine-types pc-1.2 and older, and prints a
warning in case the requested configuration won't get the correct

I couldn't think of a better way to warn about broken topology when in

probably be buried in a log file somewhere, but it's better than
nothing.

2969475869 pc: Reverse pc_init_pci() compatibility logic
Currently, the pc-1.4 machine init function enables PV EOI and then
calls the pc-1.2 machine init function. The problem with this approach
is that now we can't enable any additional compatibility code inside the
pc-1.2 init function because it would end up enabling the compatibility
behavior on pc-1.3 and pc-1.4 as well.

This reverses the logic so that the pc-1.2 machine init function will
disable PV EOI, and then call the pc-1.4 machine init function.

This way we can change older machine-types to enable compatibility
behavior, and the newer machine-types (pc-1.3, pc-q35-1.4 and
pc-i440fx-1.4) would just use the default behavior.

(This means that one nice side-effect of this change is that pc-q35-1.4
will get PV EOI enabled by default, too)

It would be interesting to eventually change pc_init_pci_no_kvmclock()
and pc_init_isa() to reuse pc_init_pci_1_2() as well (so we don't need
to duplicate compatibility code on those two functions). But this will
be probably much easier to do after we create a PCInitArgs struct for
the PC initialization arguments, and/or after we use global-properties
to implement the compatibility modes present in pc_init_pci_1_2().

8cb6bfb54e vmware_vga: fix out of bounds and invalid rects updating
This is a follow up for several attempts to fix this issue.

Previous incarnations:

1. http://thread.gmane.org/gmane.linux.ubuntu.bugs.general/3156089
https://bugs.launchpad.net/bugs/918791
"qemu-kvm dies when using vmvga driver and unity in the guest" bug.
Fix by Serge Hallyn:
 https://launchpadlibrarian.net/94916786/qemu-vmware.debdiff
This fix is incomplete, since it does not check width and height
for being negative.  Serge weren't sure if that's the right place
to fix it, maybe the fix should be up the stack somewhere.

2. http://thread.gmane.org/gmane.comp.emulators.qemu/166064
by Marek Vasut: "vmware_vga: Redraw only visible area"

This one adds the (incomplete) check to vmsvga_update_rect_delayed(),
the routine just queues the rect updating but does no interesting
stuff.  It is also incomplete in the same way as patch by Serge,
but also does not touch width&height at all after adjusting x&y,
which is wrong.

As far as I can see, when processing guest requests, the device
places them into a queue (vmsvga_update_rect_delayed()) and
processes this queue in different place/time, namely, in
vmsvga_update_rect().  Sometimes, vmsvga_update_rect() is
called directly, without placing the request to the gueue.
This is the place this patch changes, which is the last
(deepest) in the stack.  I'm not sure if this is the right
place still, since it is possible we have some queue optimization
(or may have in the future) which will be upset by negative/wrong
values here, so maybe we should check for validity of input
right when receiving request from the guest (and maybe even
use unsigned types there).  But I don't know the protocol
and implementation enough to have a definitive answer.

But since vmsvga_update_rect() has other sanity checks already,
I'm adding the missing ones there as well.

Cc'ing BALATON Zoltan and Andrzej Zaborowski who shows in `git blame'
output and may know something in this area.

If this patch is accepted, it should be applied to all active
stable branches (at least since 1.1, maybe even before), with
minor context change (ds_get_*(s->vga.ds) => s->*).  I'm not
Cc'ing -stable yet, will do it explicitly once the patch is
accepted.

BTW, these checks use fprintf(stderr) -- it should be converted
to something more appropriate, since stderr will most likely
disappear somewhere.

Align the device tree blob to a 4KB boundary, not to QEMU's
idea of a page boundary -- the latter is the smallest possible
page size for the architecture, which on ARM is 1KB.
The documentation for Linux does not impose separation
or alignment requirements on the device tree blob, but
in practice some kernels will happily trash the entire
page the initrd ends in after they have finished uncompressing
the initrd. So 4KB-align the DTB to ensure it does not get

d09acb9b5e fw_cfg: Splash image loader can overrun a stack variable, fix
read_splashfile() passes the address of an int variable as size_t *
parameter to g_file_get_contents(), with a cast to gag the compiler.

No problem on machines where sizeof(size_t) == sizeof(int).

Happens to work on my x86_64 box (64 bit little endian): the least
significant 32 bits of the file size end up in the right place
(caller's variable file_size), and the most significant 32 bits
clobber a place that gets assigned to before its next use (caller's
variable file_type).

I'd expect it to break on a 64 bit big-endian box.

Fix up the variable types and drop the problematic cast.

e0dfe5b189 openpic: add basic support for MPIC v4.2
Besides the new value in the version register, this provides:
- ILR support, which includes:
  - IDR becoming a pure CPU bitmap, allowing 32 CPUs
  - machine check output support (though other parts of QEMU need to
    be fixed for it to do something other than immediately reboot the
    guest)
- dummy error interrupt support (EISR0/EIMR0 read as zero)
  - actually all FSL MPICs get all summary registers returning zero for now,
    which includes EISR0/EIMR0

Various refactoring is done to support these changes and to ease
new functionality (e.g. a more flexible way of declaring regions).

Just as the code was already not a full implementation of MPIC v2.0,
this is not a full implementation of MPIC v4.2 -- e.g. it still has only
one bank of MSIs.

03274d44f6 openpic: fix timer address decoding
The timer memory range begins at 0x10f0, so that address 0x1120 shows
up as 0x30, 0x1130 shows up as 0x40, etc.  However, the address
decoding (other than TFRR) is not adjusted for this, causing the
wrong registers to be accessed.

f40c360c0d openpic: fix remaining issues from idr-to-destmask conversion
openpic_update_irq() was checking idr rather than destmask, treating
it as if it were a simple bitmap of cpus.  Changed to use destmask.

IPI delivery was removing bits directly from .idr, without calling
write_IRQreg_idr so that the change could be conveyed to destmask.
Changed to use destmask directly.

Save/restore destmask when serializing, as due to the IPI change it
cannot be reproduced from idr.

1ea1ce8ac3 pseries: Adjust default VIO address allocations to play better with libvirt
Currently, if VIO devices for pseries don't have addresses explicitly
allocated, they get automatically numbered from 0x1000.  This is in the
same general range that libvirt will typically assign VIO device addresses.

That means that if there is a device libvirt doesn't know about, and it
gets an address assigned before the libvirt assigned devices are processed,
we can end up with an address conflict (qemu will abort with an error).

While the real solution is to teach libvirt about the other devices, so it
can correctly manage the whole allocation, this patch reduces the interim
inconvenience by moving qemu allocations to a range that libvirt is less
likely to conflict with.

Because the guest gets the device addresses through the device tree, these
addresses are truly arbitrary and can be changed without breaking guests.

caae58cba0 pseries: Improve handling of multiple PCI host bridges
Multiple - even many - PCI host bridges (i.e. PCI domains) are very
common on real PAPR compliant hardware.  For reasons related to the
PAPR specified IOMMU interfaces, PCI device assignment with VFIO will
generally require at least two (virtual) PHBs and possibly more
depending on which devices are assigned.

At the moment the qemu PAPR PCI code will not deal with this well,
leaving several crucial parameters of PHBs other than the default one
uninitialized.  This patch reworks the code to allow this.

Every PHB needs a unique BUID (Bus Unit Identifier, the id used for
the PAPR PCI related interfaces) and a unique LIOBN (Logical IO Bus
Number, the id used for the PAPR IOMMU related interfaces).  In
addition they need windows in CPU real address space to access PCI
memory space, PCI IO space and MSIs.  Properties are added to the PCI
host bridge qdevice to allow configuration of all these.

To simplify configuration of multiple PHBs for common cases, a
convenience "index" property is also added.  This can be set instead
of the low-level properties, and will generate suitable values for the
other parameters, different for each index value.

7e6ccd9c15 balloon: re-enable balloon stats
The statistics are now available through device properties via a
polling mechanism. First a client has to enable polling, then it
can query available stats.

Polling is enabled by setting an update interval (in seconds)
to a property named guest-stats-polling-interval, like this:

{ "execute": "qom-set",
  "arguments": { "path": "/machine/peripheral-anon/device[1]",
                 "property": "guest-stats-polling-interval", "value": 4 } }

Then the available stats can be retrieved by querying the
guest-stats property. The returned object is a dict containing
all available stats. Example:

{ "execute": "qom-get",
  "arguments": { "path": "/machine/peripheral-anon/device[1]",
  "property": "guest-stats" } }

{
    "return": {
        "stats": {
            "stat-swap-out": 0,
            "stat-free-memory": 844943360,
            "stat-minor-faults": 219028,
            "stat-major-faults": 235,
            "stat-total-memory": 1044406272,
            "stat-swap-in": 0
        },

b37a2e4576 Revert "serial: fix retry logic"
This reverts commit 67c5322d70:

    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 thoug
    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.

Even if the previous logic was never worked, new logic breaks stuff -
namely,

 qemu -enable-kvm -nographic -kernel /boot/vmlinuz-$(uname -r) -append console=ttyS0 -serial pty

the above command will cause the virtual machine to stuck at startup
using 100% CPU till one connects to the pty and sends any char to it.

Note this is rather typical invocation for various headless virtual
machines by libvirt.

So revert this change for now, till a better solution will be found.

038c1879a0 qxl: change rom size to 8192
This is a simpler solution to 869981, where migration breaks since qxl's
rom bar size has changed. Instead of ignoring fields in QXLRom, which is what has
actually changed, we remove some of the modes, a mechanism already
accounted for by the guest. The modes left allow for portrait and
landscape only modes, corresponding to orientations 0 and 1.
Orientations 2 and 3 are dropped.

Added assert so that rom size will fit the future QXLRom increases via
spice-protocol changes.

This patch has been tested with 6.1.0.10015. With the newer 6.1.0.10016
there are problems with both "(flipped)" modes prior to the patch, and
the patch loses the ability to set "Portrait" modes. But this is a
separate bug to be fixed in the driver, and besides the patch doesn't
affect the new arbitrary mode setting functionality.

cf139388ad dataplane: support viostor virtio-pci status bit setting
The viostor virtio-blk driver for Windows does not use the
VIRTIO_CONFIG_S_DRIVER bit.  It only sets the VIRTIO_CONFIG_S_DRIVER_OK
bit.

The viostor driver refreshes the virtio-pci status byte sometimes while
the guest is running.  We misinterpret 0x4 (VIRTIO_CONFIG_S_DRIVER_OK)
as an indication that virtio-blk-data-plane should be stopped since 0x2
(VIRTIO_CONFIG_S_DRIVER) is missing.  The result is that the device
becomes unresponsive.

cd7fdfe59f dataplane: avoid reentrancy during virtio_blk_data_plane_stop()
When dataplane is stopping, the s->vdev->binding->set_host_notifier(...,
false) call can invoke the virtqueue handler if an ioeventfd
notification is pending.  This causes hw/virtio-blk.c to invoke
virtio_blk_data_plane_start() before virtio_blk_data_plane_stop()
returns!

The result is that we try to restart dataplane while trying to stop it
and the following assertion is raised:

  msix_set_mask_notifier: Assertion `!dev->msix_mask_notifier' failed.

Although the code was intended to prevent this scenario, the s->started
boolean isn't enough.  Add s->stopping so that we can postpone clearing
s->started until we've completely stopped dataplane.

This way, virtqueue handler calls during virtio_blk_data_plane_stop()
are ignored.  When dataplane is legitimately started again later we
already self-kick ourselves to resume processing.

ecd584b836 hw/dma.c: Fix conversion of ioport_register* to MemoryRegion
The commit 5822993368 introduced a 1-shift for
some offset in DMA emulation.

Before the previous commit, which converted ioport_register_* to
MemoryRegion, the DMA controller registered 8 ioports with the following
formula:
base + ((8 + i) << d->shift) where 0 <= i < 8
When an IO occured within a Memory Region, DMA callback receives an
offset relative to the start address. Here the start address is:
base + (8 << d->shift).
The offset should be: (i << d->shift). After the shift is reverted, the
offsets are 0..7 not 1..8.

Fixes LP#1089996.

501378c3af ide: issue discard asynchronously but serialize the pieces
Now that discard can take a long time, make it asynchronous.
Each LBA range entry is processed separately because discard
can be an expensive operation.

80bc2e8d80 ide: fix TRIM with empty range entry
ATA-ACS-3 says "If the two byte range length is zero, then the LBA
Range Entry shall be discarded as padding."  iovecs are used as if
they are linearized, so it is incorrect to discard the rest of
this iovec.
