5e6ffddef6 eepro100: convert to memory API
Note: the existing code aliases the flash BAR into the MMIO bar.  This is
probably a bug.  This patch does not correct the problem.

257a737558 Check fread() results to avoid gcc 4.6 warnings
When compiling with gcc 4.6, some code in fw_cfg.c complains that fop_ret
is assigned but not used (which is true).  However, it looks like the
meaningless assignments to fop_ret were done to suppress other gcc warnings
due to the fact that fread() is labelled as warn_unused_result in glibc.

This patch avoids both errors, by actually checking the fread() result code
and dropping out with an error message if it fails.

30fb2ca603 balloon: Separate out stat and balloon handling
Passing on '0' as ballooning target to indicate retrieval of stats is
bad API.  It also makes 'balloon 0' in the monitor cause a segfault.
Have two different functions handle the different functionality instead.

Detailed explanation from Markus's review:

1. do_info_balloon() is an info_async() method.  It receives a callback
   with argument, to be called exactly once (callback frees the
   argument).  It passes the callback via qemu_balloon_status() and
   indirectly through qemu_balloon_event to virtio_balloon_to_target().

   virtio_balloon_to_target() executes its balloon stats half.  It
   stores the callback in the device state.

   If it can't send a stats request, it resets stats and calls the
   callback right away.

   Else, it sends a stats request.  The device model runs the callback
   when it receives the answer.

   Works.

2. do_balloon() is a cmd_async() method.  It receives a callback with
   argument, to be called when the command completes.  do_balloon()
   calls it right before it succeeds.  Odd, but should work.

   Nevertheless, it passes the callback on via qemu_ballon() and
   indirectly through qemu_balloon_event to virtio_balloon_to_target().

   a. If the argument is non-zero, virtio_balloon_to_target() executes
      its balloon half, which doesn't use the callback in any way.

      Odd, but works.

   b. If the argument is zero, virtio_balloon_to_target() executes its
      balloon stats half, just like in 1.  It either calls the callback
      right away, or arranges for it to be called later.

      Thus, the callback runs twice: use after free and double free.

Test case: start with -S -device virtio-balloon, execute "balloon 0" in
human monitor.  Runs the callback first from virtio_balloon_to_target(),
then again from do_balloon().

3e4571724f exec.h cleanup
Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.

Define global env in dyngen-exec.h.

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().

ARM: make raise_exception() static.

Convert
#include "exec.h"
to

#include "dyngen-exec.h"

104bf02eb5 revamp acpitable parsing and allow to specify complete (headerful) table
This patch almost rewrites acpi_table_add() function
(but still leaves it using old get_param_value() interface).
The result is that it's now possible to specify whole table
(together with a header) in an external file, instead of just
data portion, with a new file= parameter, but at the same time
it's still possible to specify header fields as before.

Now with the checkpatch.pl formatting fixes, thanks to
Stefan Hajnoczi for suggestions, with changes from
Isaku Yamahata, and with my further refinements.

Added options to let qemu transfer two configuration files to bios:
"bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command
    -boot splash=P,splash-time=T
P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit
is ms. With these two options, if user invoke qemu with menu=on option, then
a splash picture would be showed in a given time. For example:
    qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000
would make boot.bmp shown as a brand with 5 seconds in the booting up process.

679f4f8b17 xen: implement unplug protocol in xen_platform
The unplug protocol is necessary to support PV drivers in the guest: the
drivers expect to be able to "unplug" emulated disks and nics before
initializing the Xen PV interfaces.
It is responsibility of the guest to make sure that the unplug is done
before the emulated devices or the PV interface start to be used.

We use pci_for_each_device to walk the PCI bus, identify the devices and
disks that we want to disable and dynamically unplug them.

Changes in v2:

- use PCI_CLASS constants;

- replace pci_unplug_device with qdev_unplug;

- do not import hw/ide/internal.h in xen_platform.c;

Changes in v3:

- introduce piix3-ide-xen, that support hot-unplug;

- move the unplug code to hw/ide/piix.c;

- just call qdev_unplug from xen_platform.c to unplug the IDE disks;

59d21e537b xen: make xen_enabled even more clever
When using xen_enabled() we're currently only checking if xen is enabled
at all during the build. But what if you want to build multiple targets
out of which only one can potentially run xen code?

That means that for generic code we'll still have to fall back to the
variable and potentially slow the code down, but it's not as important as
that is mostly xen device emulation which is not touched for non-xen targets.

The target specific code however can with this patch see that it's unable to
ever execute xen code. We can thus always return 0 on xen_enabled(), giving
gcc enough hints to evict the mapcache code from the target memory management
code.

021a131860 virtio-serial: Clean up virtser_bus_dev_print() output
Old version looks like this in info qtree (last four lines):

          dev: virtconsole, id ""
            dev-prop: is_console = 1
            dev-prop: nr = 0
            dev-prop: chardev = <null>
            dev-prop: name = <null>
             dev-prop-int: id: 0
             dev-prop-int: guest_connected: 1
             dev-prop-int: host_connected: 0
             dev-prop-int: throttled: 0

Indentation is off, and "dev-prop-int" suggests these are properties
you can configure with -device, which isn't the case.  The other
buses' print_dev() callbacks don't do that.  For instance, PCI's
output looks like this:

        class Ethernet controller, addr 00:03.0, pci id 1af4:1000 (sub 1af4:0001)
        bar 0: i/o at 0xffffffffffffffff [0x1e]
        bar 1: mem at 0xffffffffffffffff [0xffe]
        bar 6: mem at 0xffffffffffffffff [0xfffe]

Change virtser_bus_dev_print() to that style.  Result:

          dev: virtconsole, id ""
            dev-prop: is_console = 1
            dev-prop: nr = 0
            dev-prop: chardev = <null>
            dev-prop: name = <null>
            port 0, guest on, host off, throttle off

6e1db57b2a qemu-char: Print strerror message on failure
The only way for chardev drivers to communicate an error was to return a NULL

6141dbfe0a report serial devices created with -device in the PIIX4 config space
Serial and parallel devices created with -device are not reported in
the PIIX4 configuration space, and are hence not picked up by the DSDT.
This upsets Windows, which hides them altogether from the guest.

To avoid this, check at the end of machine initialization whether the
corresponding I/O ports have been registered.  The new function in
ioport.c does this; this also requires a tweak to isa_unassign_ioport.

I left the comment in piix4_pm_initfn since the registers I moved do
seem to match the 82371AB datasheet.  There are some quirks though.
We are setting this bit:

    "Device 8 EIO Enable (EIO_EN_DEV8)—R/W. 1=Enable PCI access to the
    device 8 enabled I/O ranges to be claimed by PIIX4 and forwarded
    to the ISA/EIO bus. 0=Disable. The LPT_MON_EN must be set to enable
    the decode."

but not LPT_MON_EN (bit 18 at 50h):

    LPT Port Enable (LPT_MON_EN)—R/W. 1=Enable accesses to parallel
    port address range (LPT_DEC_SEL) to generate a device 8 (parallel
    port) decode event. 0=Disable.

We're also setting the LPT_DEC_SEL field (that's the 0x60 written to
63h) to 11, which means reserved, rather than to 01 (378h-37Fh).

Likewise we're not setting SA_MON_EN, SB_MON_EN (respectively bit 14
and bit 16 at address 50h) for the serial ports.  However, we're setting
COMA_DEC_SEL and COMB_DEC_SEL correctly, unlike the corresponding register
for the parallel port.

All these fields are left as they are, since they are probably only
meant to be used in the DSDT.

0219d73283 virtio-console: Prevent abort()s in case of host chardev close
A host chardev could close just before the guest sends some data to be
written.  This will cause an -EPIPE error.  This shouldn't be propagated
to virtio-serial-bus.

Ideally we should close the port once -EPIPE is received, but since the
chardev interface doesn't return such meaningful values to its users,
all we get is -1 for any kind of error.  Just return 0 for now and wait
for chardevs to return better error messages to act better on the return
messages.

0f51726adc xen_console: support the new extended xenstore protocol
Since CS 21994 on xen-unstable.hg and CS
466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few
changes have been introduced to the PV console xenstore protocol, as
described by the document docs/misc/console.txt under xen-unstable.hg.

From the Qemu point of view, very few modifications are needed to
correctly support the protocol: read from xenstore the "output" node
that tell us what the output of the PV console is going to be.
In case the output is a tty, write to xenstore the device name.

Changes in v2:

- fix error paths: free malloc'ed strings and close the xenstore
connection before returning;

- remove useless snprintf in xenstore_store_pv_console_info if i == 0.

Changes in v3:

- replace xs_daemon_open/xs_daemon_close with xs_open/xs_close.

Changes in v4:

- add a compatibility implementation of xs_open/xs_close.

Changes in v5:

- fix code style.

with the "usb-ehci: cleanup port reset handling" patch in place no callers
are calling usb_attach(port, NULL) for a port where port->dev is NULL.

Doing that makes no sense as that causes the port detach op to get called
for a port with nothing attached. Add an assert that port->dev != NULL when
dev == NULL, and remove the check for not having a port->dev in the dev == NULL
case.

4706ab6cc0 usb: Replace device_destroy bus op with a child_detach port op
Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.

Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

40c4ed3f95 ide: Ignore reads during PIO in and writes during PIO out
This fixes https://bugs.launchpad.net/qemu/+bug/786209:

    When the DRQ_STAT bit is set, the IDE core permits both data reads
    and data writes, regardless of whether the current transfer was
    initiated as a read or write.

    This potentially leaks uninitialized host memory into the guest,
    if, before doing anything else to an IDE device, the guest begins a
    write transaction (e.g. WIN_WRITE), but then *reads* from the IO
    port instead of writing to it.
