a0436e9239 ide: Add handler to ide_cmd_table
As a preparation for moving all IDE commands into their own function
like in the ATAPI code, introduce a 'handler' callback to ide_cmd_table.

Commands using this new infrastructure get some things handled
automatically:

* The BSY flag is set before calling the handler (in order to avoid bugs
  like the one fixed in f68ec837) and reset on completion.

* The (obsolete) DSC flag in the status register is set on completion if
  the command is flagged with SET_DSC in the command table

* An IRQ is triggered on completion.

* The error register and the ERR flag in the status register are cleared
  before calling the handler and on completion it is asserted that
  either none or both of them are set.

No commands are converted at this point.

address spaces while there are actually a lot more other AddressSpace
structs created by PCI and VIO devices. Those devices do not normally

052e87b073 memory: make section size a 128-bit integer
So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes

An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

e1123015a5 pc: Make -no-fd-bootchk stick across boot order changes
Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS.  It was added back in 2006 (commit 52ca8d6a).

Two years later, commit 0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set().  It unconditionally clears
the floppy signature bit in CMOS.

Commit e0f084bf added -boot option once to automatically change the
boot order on first reset.  Reuses pc_boot_set(), thus also clears the
floppy signature bit.  Commit d9346e81 took care to preserve this
behavior.

Thus, -no-fd-bootchk applies to any number of boots.  Except it
applies just to the first boot with -boot once, and never after
boot_set.  Weird.  Make it stick instead: set the bit according to
-no-fd-bootchk in pc_boot_set().

c1990468d5 wdt_i6300esb: fix vmstate versioning
When this VMSD was introduced it's version fields were set to
sizeof(I6300State), making them essentially random from build to build,
version to version.

To fix this, we lock in a high version id and low minimum version id to
support old->new migration from all prior versions of this device's
state. This should work since the device state has not changed since
its introduction.

The potentially breaks migration from 1.5+ to 1.5, but since the
versioning was essentially random prior to this patch, new->old
migration was not consistently functional to begin with.

53254e569f scsi-generic: fix sign extension of READ CAPACITY(10) data
Issuing the READ CAPACITY(10) command in the guest will cause QEMU
to update its knowledge of the maximum accessible LBA in the disk.
The recorded maximum LBA will be wrong if the disk is bigger than
1TB, because ldl_be_p returns a signed int.

When this is fixed, a latent bug will be unmasked.  If the READ
CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must
not overwrite the previously-known maximum accessible LBA, or the guest
will fail to access the disk above the first 2TB.

7721c7f7c2 scsi: reset cdrom tray statuses on scsi_disk_reset
Tray statuses should be also reset. Some guests may lock the tray and
right after resetting the guest it should be unlocked and closed. This
is done on power-on, reset and resume from suspend/hibernate on bare-metal.

This fix is already committed for IDE CD.
Check the commit a7f3d65b65.

Test results on bare-metal:
  - on reset/power-on the CD-ROM tray is closed even before the monitor
    is turned on
  - on resume from suspend/hibernate the tray is also closed before
    the monitor is turned on

From test results it seems that this behavior is OS and probably BIOS
independent.

Acking a level sensitive interrupt should have no effect if the
interrupt pin is still asserted. The current implementation requires

means an ACK can clear a level sensitive interrupt, until the original

Fix by keeping track of the interrupt pin state and setting ISR based
on this every time update_irq() is called.

Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci
storage device.

NVMe is an open, industry driven storage specification defining
an optimized register and command set designed to deliver the full
capabilities of non-volatile memory on PCIe SSDs. Further information
may be found on the organizations website at:

http://www.nvmexpress.org/

This commit implements the minimum from the specification to work with
existing drivers.

If the user fails to specify 'chardev' or 'shm' then we cannot continue.
Exit right away so that we don't invoke shm_open(3) with a NULL pointer.

It would be nice to replace exit(1) with error returns in the PCI device
.init() function, but leave that for another patch since exit(1) is
currently used elsewhere.

ffce9ebbb6 target-i386: Update model values on Conroe/Penryn/Nehalem CPU models
The CPUID model values on Conroe, Penryn, and Nehalem are too
conservative and don't reflect the values found on real Conroe, Penryn,
and Nehalem CPUs.

This causes at least one known problems: Windows XP disables sysenter
when (family == 6 && model <= 2), but Skype tries to use the sysenter
instruction anyway because it is reported as available on CPUID, making
it crash.

This patch sets appropriate model values that correspond to real Conroe,
Penryn, and Nehalem CPUs.

f68ec8379e ide: Set BSY bit during FLUSH
The implementation of the ATA FLUSH command invokes a flush at the block
layer, which may on raw files on POSIX entail a synchronous fdatasync().
This may in some cases take so long that the SLES 11 SP1 guest driver
reports I/O errors and filesystems get corrupted or remounted read-only.

Avoid this by setting BUSY_STAT, so that the guest is made aware we are
in the middle of an operation and no ATA commands are attempted to be
processed concurrently.

b64ec4e4ad block: add block driver read only whitelist
We may want to include a driver in the whitelist for read only tasks
such as diagnosing or exporting guest data (with libguestfs as a good
example). This patch introduces a readonly whitelist option, and for
backward compatibility, the old configure option --block-drv-whitelist
is now an alias to rw whitelist.

Drivers in readonly list is only permitted to open file readonly, and
returns -ENOTSUP for RW opening.

E.g. To include vmdk readonly, and others read+write:
    ./configure --target-list=x86_64-softmmu \
                --block-drv-rw-whitelist=qcow2,raw,file,qed \

58ee9b0ae0 xen_machine_pv: do not create a dummy CPU in machine->init
This fixes a regression introduced by:

commit 62fc403f11
Author: Igor Mammedov <imammedo@redhat.com>
Date:   Mon Apr 29 18:54:13 2013 +0200

    target-i386: Attach ICC bus to CPU on its creation

    X86CPU should have parent bus so it could provide bus for child APIC.

The commit makes it mandatory to pass a valid ICC bus to cpu_x86_create,
but cpu_x86_init just passes NULL to it.
xen_machine_pv uses cpu_x86_init, therefore it has been broken.

This patch fixes the problem by removing the dummy CPU creation

bbfa18fca4 qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path
Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

dafb82e0fc pc_sysfw: allow flash (-pflash) memory to be used with KVM
When pc-sysfw.rom_only == 0, flash memory will be
usable with kvm. In order to enable flash memory mode,
a pflash device must be created. (For example, by
using the -pflash command line parameter.)

Usage of a flash memory device with kvm requires
KVM_CAP_READONLY_MEM, and kvm will abort if
a flash device is used with an older kvm which does
not support this capability.

If a flash device is not used, then qemu/kvm will
operate in the original rom-mode.

dade922f35 isapc: Fix non-KVM qemu boot (read/write memory for isapc BIOS)
The isapc machine with seabios currently requires the BIOS region
to be read/write memory rather than read-only memory.

KVM currently cannot support the BIOS as a ROM region, but qemu
in non-KVM mode can. Based on this, isapc machine currently only
works with KVM.

To work-around this isapc issue, this change avoids marking the
BIOS as readonly for isapc.

This change also will allow KVM to start supporting ROM mode
via KVM_CAP_READONLY_MEM.

db431f6adc hw/9pfs: Be robust against paths without FS_IOC_GETVERSION
9P optionally uses the FS_IOC_GETVERSION ioctl to get information about
a file's version (sometimes called generation number).

The code checks for supported filesystems at mount time, but some paths
may come from other mounted filesystems.

Change it to treat unsupported paths the same as unsupported
filesystems, returning 0 in both cases.

Note: ENOTTY is the error code for an unsupported ioctl.

This fix allows booting a linux kernel with the same / filesystem as the
host; otherwise the boot fails when mounting devtmpfs.

5f9a5ea1c0 memory: Rename readable flag to romd_mode
"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region
flag, but it only applies to rom_device regions.

So rename the flag and the function to modify it after the original term
"ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode
with direct access. In any case, the scope of the flag is clearer now.

00b7ade807 rtl8139: flush queued packets when RxBufPtr is written
Net queues support efficient "receive disable".  For example, tap's file
descriptor will not be polled while its peer has receive disabled.  This
saves CPU cycles for needlessly copying and then dropping packets which
the peer cannot receive.

rtl8139 is missing the qemu_flush_queued_packets() call that wakes the
queue up when receive becomes possible again.

As a result, the Windows 7 guest driver reaches a state where the
rtl8139 cannot receive packets.  The driver has actually refilled the
receive buffer but we never resume reception.

The bug can be reproduced by running a large FTP 'get' inside a Windows
7 guest:

  $ qemu -netdev tap,id=tap0,...
         -device rtl8139,netdev=tap0

The Linux guest driver does not trigger the bug, probably due to a
different buffer management strategy.

913b4b6bf3 hw/pci-host/versatile.c: Provide property for forcing broken IRQ mapping
Although we try our best to automatically detect broken versions
of Linux which assume the old broken IRQ mapping we used to implement
for our model of the Versatile PCI controller, it turns out that
some particularly new kernels manage to outwit the autodetection.

We therefore provide a property for enabling the old broken IRQ
mapping, so that if users happen to have such a kernel they can
work around its deficiencies with the command line option:
  -global versatile_pci.broken-irq-mapping=1

33201b51cb Revert "versatile_pci: Put the host bridge PCI device at slot 29"
This reverts commit 5f37ef92b7.
It turns out that some kernels incorrectly depend on the
old QEMU behaviour of not putting the host PCI bridge device
where the hardware puts it, because they use a swizzling IRQ
mapping which is incorrect but happens to match up with old
broken QEMU when the slot number mod 4 is zero. Since we
start PCI devices at 11, if we put the host bridge at 29
then the first real PCI device goes at 11 and doesn't work.
Not putting the host bridge at 29 means it defaults to 11,
so the first real PCI device is at 12 and works.

Since continuing with the old behaviour doesn't cause problems
for kernels which do work with hardware, the simplest fix for
this is to revert the change.

0a2b5e3a78 qxl: Call spice_qxl_driver_unload from qxl_enter_vga_mode
With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
know what part of the primary to use for each monitor. If the guest driver
does not support this, the server sends messages to the client for a
single monitor spanning the entire primary.

As soon as the guest calls spice_qxl_monitors_config_async once, the server
sets the red_worker driver_has_monitors_config flag and stops doing this.

This is a problem when the driver gets unloaded, for example after a reboot
or when switching to a text vc with usermode mode-setting under Linux.

To reproduce this start a multi-mon capable Linux guest which uses
usermode mode-setting and then once X has started switch to a text vc. Note
how the client window does not only not resize, if you try to resize it
manually you always keep blackborders since the aspect is wrong.

This patch calls a new spice-server method called spice_qxl_driver_unload
which clears the driver_has_monitors_config flag inside the server, thereby
fixing this.

- The check was based on the minus of unsigned values which can overflow
- It was done after .{set|get}_config() which can lead crash when config_len

Fix this by:

- Validate the address in virtio_pci_config_{read|write}() before
  .{set|get}_config
- Use addition instead minus to do the validation

9822261ce3 uhci: Use an intermediate buffer for usb packet data
Due to various unfortunate reasons we cannot reliable detect a guest
cancelling a packet as soon as it happens, instead we detect cancels
with some delay.

When packets are handled async, and we directly pass the guest memory for
the packet to the usb-device as iovec, this means that the usb-device can
write to guest-memory which the guest has already re-used for other purposes
-> not good!

This patch fixes this by adding an intermediate buffer and writing back not
only the result, but also the data, of async completed packets when scanning
the schedule.

receive packets. If a guest NIC is stopped during transfer (rmmod or
ifdown), it may still have packets in a queue which have to be send
to the guest before QEMU enables polling of a "tap" interface via
tap_update_fd_handler().

However the spapr_llan device was missing the qemu_flush_queued_packets()
call so the tap_send_completed() callback was never called and therefore
"tap" interface polling was not enabled ever.

The patch fixes this problem.

d4261662b6 pseries: Factor out check for out-of-bounds LIOBN
PAPR defines LIOBNs (Logical IO Bus Numbers) to be 32-bit, and we check for
values that aren't in the code for H_PUT_TCE.  This patch factors the check
into spapr_tce_find_by_liobn(), which already checks if a 32-bit LIOBN
actually exists.  This will become more important as future patches add
other hypercalls which need to look up a LIOBN.

At the same time we fix the typo in the message.

0514ef2fbb target-i386: Replace cpuid_*features fields with a feature word array
This replaces the feature-bit fields on both X86CPU and x86_def_t
structs with an array.

With this, we will be able to simplify code that simply does the same
operation on all feature words (e.g. kvm_check_features_against_host(),
filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit
property lookup/registration, and the proposed "feature-words" property)

The following field replacements were made on X86CPU and x86_def_t:

  (cpuid_)features         -> features[FEAT_1_EDX]
  (cpuid_)ext_features     -> features[FEAT_1_ECX]
  (cpuid_)ext2_features    -> features[FEAT_8000_0001_EDX]
  (cpuid_)ext3_features    -> features[FEAT_8000_0001_ECX]
  (cpuid_)ext4_features    -> features[FEAT_C000_0001_EDX]
  (cpuid_)kvm_features     -> features[FEAT_KVM]

Commit 14f9b664 (hw/virtio-net.c: set config size using host features) tries to
calculate config size based on the host features. But it forgets the
VIRTIO_NET_F_MAC were always set for qemu later. This will lead a zero config
len for virtio-net device when both VIRTIO_NET_F_STATUS and VIRTIO_NET_F_MQ were
disabled form command line. Then qemu will crash when user tries to read the
config of virtio-net.

Fix this by counting VIRTIO_NET_F_MAC and make sure the config at least contains
the mac address.
