John Snow fac7aa7fc2 ahci: properly shadow the TFD register
In a real AHCI device, several S/ATA registers are mirrored or shadowed
within the AHCI register set. These registers are not updated
synchronously for each read access, but are instead updated after a
Device-to-Host Register FIS packet is received. The D2H FIS contains
the values from these registers on the device.

In QEMU, by reaching directly into the device to grab these bits before
they are "sent," we may introduce race conditions where unexpected
values are present "before they are sent" which could cause issues for
some guests, particularly if an attempt is made to read the PxTFD
register prior to enabling the port, where incorrect values will be read.

This patch also addresses the boot-time values for the PxTFD and PxSIG
registers to bring them in line with the AHCI 1.3 specification.

Lastly, several fields (PxTFD, PxSIG and PxSACT) are read-only,
and any attempts to write to them should be ignored.

John Snow c8b5b20f81 ahci: MSI capability should be at 0x80, not 0x50.
In the Intel ICH9 data sheet, the MSI capability offset
in the PCI configuration space for ICH9 AHCI devices is
specified to be 0x80.

Further, the PCI capability pointer should always point
to 0x80 in ICH9 devices, despite the fact that AHCI 1.3
specifies that it should be pointing to PMCAP (Which in
this instance would be 0x70) to maintain adherence to
the Intel data sheet specifications and real observed behavior.

Fam Zheng 0d910cfeaf ide/ahci: Check for -ECANCELED in aio callbacks
Before, bdrv_aio_cancel will either complete the request (like normal)
and call CB with an actual return code, or skip calling the request (for
example when the IO req is not submitted by thread pool yet).

We will change bdrv_aio_cancel to do it differently: always call CB
before return, with either [1] a normal req completion ret code, or [2]
ret == -ECANCELED. So the callers' callback must accept both cases. The
existing logic works with case [1], but not [2].

The simplest transition of callback code is do nothing in case [2], just
as if the CB is not called by the bdrv_aio_cancel() call.

John Snow d735b620b5 ide/atapi: Mark non-data commands as complete
When the command completion code in IDE and AHCI
was unified to put all command completion inside
of a callback, "cmd_done," we neglected to
ensure that all AHCI/ATAPI command paths would
eventually register as finished. for the PCI
interface to IDE this is not a problem because
cmd_done is a nop, but the AHCI implementation
needs to send a D2H_REG_FIS and interrupt back
to the guest to inform of completion.

This patch adds calls to ide_stop_transfer,
which calls ide_cmd_done, inside of
ide_atapi_cmd_ok and ide_atapi_cmd_error.

This fixes regressions observed by trying to boot QEMU
with a Fedora 20 live CD under Q35/AHCI, which uses
ATAPI command 0x00, which is a status check that may
cause a hang because we never complete, and ATAPI
command 0x56, which is unsupported by our current
implementation and results in an error that we never
report back to the guest.

Michael S. Tsirkin 438f92ee9f pc: leave more space for BIOS allocations
Since QEMU 2.1, we are allocating more space for ACPI tables, so no
space is left after initrd for the BIOS to allocate memory.

Besides ACPI tables, there are a few other uses of high memory in
SeaBIOS: SMBIOS tables and USB drivers use it in particular.  These uses
allocate a very small amount of memory.  Malloc metadata also lives
there.  So we need _some_ extra padding there to avoid initrd breakage,
but not much.

John Snow found a case where RHEL5 was broken by the recent change to
ACPI_TABLE_SIZE; in his case 4KB of extra padding are fine, but just to
be safe I am adding 32KB, which is roughly the same amount of padding
that was left by QEMU 2.0 and earlier.

Move initrd to leave some space for the BIOS.

Michael S. Tsirkin 4d43d3f3c8 virtio-pci: fix migration for pci bus master
Current support for bus master (clearing OK bit)
together with the need to support guests which do not
enable PCI bus mastering, leads to extra state in
VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust
in case of cross-version migration for the case when
guests use the device before setting DRIVER_OK.

Rip out VIRTIO_PCI_FLAG_BUS_MASTER_BUG and implement a simpler
work-around: treat clearing of PCI_COMMAND as a virtio reset.  Old
guests never touch this bit so they will work.

As reset clears device status, DRIVER and MASTER bits are
now in sync, so we can fix up cross-version migration simply
by synchronising them, without need to detect a buggy guest
explicitly.

Drop tracking VIRTIO_PCI_FLAG_BUS_MASTER_BUG completely.

As reset makes the device quiescent, in the future we'll be able to drop
checking OK bit in a bunch of places.

Michael S. Tsirkin 9e8e8c4865 Revert "virtio: don't call device on !vm_running"
This reverts commit a1bc7b827e422e1ff065640d8ec5347c4aadfcd8.
    virtio: don't call device on !vm_running
It turns out that virtio net assumes that vm_running
is updated before device status callback in many places,
so this change leads to asserts.
Previous commit fixes the root issue that motivated
a1bc7b827e422e1ff065640d8ec5347c4aadfcd8 differently,
so there's no longer a need for this change.

In the future, we might be able to drop checking vm_running
completely, and check vm state directly.

Eduardo Habkost b3ce84fea4 qdev: Move global validation to a single function
Currently GlobalProperty.not_used=false has multiple meanings:

* It may be a property for a hotpluggable device, which may or may not
  have been used by a device;
* It may be a machine-type-provided property, which may or may not have
  been used by a device.
* It may be a user-provided property that was actually not used by
  any device.

Simplify the logic by having two separate fields: 'user_provided' and
'used'. This allows the entire global property validation logic to be
contained in a single function, and allows more specific error messages.

keep the floating output pins to stay high, the old state variable had to be

Edge level interrupts and I/O were tested under Linux 3.14. Level interrupt

Stefan Hajnoczi 745a9bb9cd dataplane: fix virtio_blk_data_plane_create() op blocker error path
Commit 3718d8ab65 ("block: Replace in_use
with operation blocker") broke the error path because it consumed
local_err instead of propagating it.

The caller has no way to know that the function failed.  This caused
virtio-blk to start "successfully" even though there was a fatal
dataplane error.

Steps to reproduce:

  $ qemu-system-x86_64 -enable-kvm -object iothread,id=iothread0 \
                       -drive if=none,id=drive0,file=a.img \
  (qemu) drive_mirror drive0 /tmp/foo.img
  (qemu) device_add virtio-blk-pci,iothread=iothread0,drive=drive0

Expected result:

  Since the mirror block job is using drive0 it is not possible to start
  virtio-blk data-plane.

  device_add fails and the PCI adapter is not added.

Actual result:

  device_add completes and the PCI adapter is added.

Pavel Dovgalyuk 2c9ecdeb9f piix: do not set irq while loading vmstate
This patch avoids setting an irq while loading the state of the ISA bridge.
Because the i8259 has not been deserialized yet, raising an interrupt
could bring the system out-of-sync with the migration source.  For example,
the migration source could have masked the interrupt in the i8259. On the
destination, the i8259 device model would not know that yet and would
trigger an interrupt in the CPU.

This patch eliminates setting the irq and just restores the calculated
state fields in post_load function.  Interrupt state will be deserialized
separately through the IRR field of the i8259.

Benoît Canet 5366d0c8bc block: Make the block accounting functions operate on BlockAcctStats
This is the next step for decoupling block accounting functions from
BlockDriverState.
In a future commit the BlockAcctStats structure will be moved from
BlockDriverState to the device models structures.

Note that bdrv_get_stats was introduced so device models can retrieve the
BlockAcctStats structure of a BlockDriverState without being aware of it's
layout.
This function should go away when BlockAcctStats will be embedded in the device
models structures.
