Convert stderr messages calling error_get_pretty()
to error_report().
Timestamp is prepended by -msg timstamp option with it.
Per Markus's comment below, A conversion from fprintf() to
error_report() is always an improvement, regardless of
error_get_pretty().
http://marc.info/?l=qemu-devel&m=137513283408601&w=2
But, it is not reasonable to convert them at one time
because fprintf() is used everwhere in qemu.
So, it should be done step by step with avoiding regression.

Spice has two display interface implementations: One integrated into
the qxl graphics card, and one generic which can operate with every
qemu-emulated graphics card.
The generic one is activated in case spice is used without qxl. The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed. Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

[Issue]
When we offer a customer support service and a problem happens
in a customer's system, we try to understand the problem by
comparing what the customer reports with message logs of the
customer's system.
In this case, we often need to know when the problem happens.
But, currently, there is no timestamp in qemu's error messages.
Therefore, we may not be able to understand the problem based on
error messages.
[Solution]
Add a timestamp to qemu's error message logged by
error_report() with g_time_val_to_iso8601().

Multiple -machine options with the same ID are merged. All but the
one without an ID are to be silently ignored.
In most places, we query these options with a null ID. This is
correct.
In some places, we instead query whatever options come first in the
list. This is wrong. When the -machine processed first happens to
have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.
Example:
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on
QEMU 1.5.50 monitor - type 'help' for more information
(qemu) info kvm
kvm support: enabled
(qemu) info usb
(qemu) q
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on

USB support not enabled
(qemu) q
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on
xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
xen be core: can't open xen interface
failed to initialize Xen: Operation not permitted
Option usb is queried correctly, and the one without an ID wins,
regardless of option order.
Option accel is queried incorrectly, and which one wins depends on
option order and ID.
Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.
Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given. Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options. Downstreams
that enable KVM by default do get bitten, though.
Use qemu_get_machine_opts() to fix these bugs.

Option "once" sets up a different boot order just for the initial
boot. Boot order reverts back to normal on reset. Option "order"
changes the normal boot order.
The reversal is implemented by reset handler restore_boot_devices(),
which takes the boot order to revert to as argument.
restore_boot_devices() does nothing on its first call, because that
must be the initial machine reset. On its second call, it changes the
boot order back, and unregisters itself.
Because we register the handler right when -boot gets parsed, we can
revert to an incorrect normal boot order, and multiple -boot can
interact in funny ways.
Here's how things work without -boot once or order:
* boot_devices is "".
* main() passes machine->boot_order to to machine->init(), because
boot_devices is "". machine->init() configures firmware
accordingly. For PC machines, machine->boot_order is "cad", and
pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up.
Now consider -boot order=:
* boot_devices is "".
* -boot order= sets boot_devices to "" (no change).
* main() passes machine->boot_order to to machine->init(), because
boot_devices is "", as above.
Bug: -boot order= has no effect. Broken in commit e4ada29e.
Next, consider -boot once=a:
* boot_devices is "".
* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* main() passes boot_devices "a" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does
nothing, because it's the first call.
* Machine boots, boot order is "a".
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
Bug: boot order reverts to "" instead of machine->boot_order. The
actual boot order depends on how firmware interprets "". Broken
in commit e4ada29e.
Next, consider -boot once=a -boot order=c:
* boot_devices is "".
* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* -boot order=c sets boot_devices to "c".
* main() passes boot_devices "c" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does
nothing, because it's the first call.
* Machine boots, boot order is "c".
Bug: it should be "a". I figure this has always been broken.
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
Bug: boot order reverts to "" instead of "c". I figure this has
always been broken, just differently broken before commit
e4ada29e.
Next, consider -boot once=a -boot once=b -boot once=c:
* boot_devices is "".
* -boot once=a registers restore_boot_devices() with argument "", and
sets boot_devices to "a".
* -boot once=b registers restore_boot_devices() with argument "a", and
sets boot_devices to "b".
* -boot once=c registers restore_boot_devices() with argument "b", and
sets boot_devices to "c".
* main() passes boot_devices "c" to machine->init(), which configures
firmware accordingly. For PC machines, pc_cmos_init() writes the
boot order to RTC CMOS.
* main() calls qemu_system_reset(). This runs reset handlers.
- restore_boot_devices() gets called with argument "". Does
nothing, because it's the first call.
- restore_boot_devices() gets called with argument "a". Calls
qemu_boot_set("a") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
- restore_boot_devices() gets called with argument "b". Calls
qemu_boot_set("b") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler
unregistered.
* Machine boots, boot order is "b".
Bug: should really be "c", because that came last, and for all other
-boot options, the last one wins. I figure this was broken some
time before commit 37905d6a, and fixed there only for a single
occurence of "once".
* Machine resets (e.g. monitor command). Reset handlers run.
- restore_boot_devices() gets called with argument "". Calls
qemu_boot_set("") to reconfigure firmware. For PC machines,
pc_boot_set() writes it into RTC CMOS. Reset handler

Same bug as above: boot order reverts to "" instead of
machine->boot_order.
Fix by acting upon -boot options order, once and menu only after
option parsing is complete, and the machine is known. This is how the
other -boot options work already.

1. Invalid options are reported more nicely. Before:
qemu: unknown boot parameter 'x' in 'x=y'
After:
qemu-system-x86_64: -boot x=y: Invalid parameter 'x'
2. If -boot is given multiple times, options accumulate, just like for
-machine. Before, only options order, once and menu accumulated.
For the other ones, all but the first -boot in non-legacy syntax
got simply ignored.

Commit 047d4e151d "Unbreak -no-quit for GTK, validate SDL options" broke
build of qemu without sdl, by referencing `no_frame' variable which is defined
inside #if SDL block. Fix that by defining that variable unconditionally.
This is a better fix for the build issue introduced by that patch than
a revert. This change keeps the new functinality introduced by that patch
and just fixes the compilation. It still is not a complete fix around the
original issue (not working -no-frame et al with -display gtk), because it
makes only the legacy interface working, not the new suboption interface,
so a few more changes are needed.

Certain options (-no-frame, -alt-grab, -ctrl-grab) only make sense with SDL.
When compiling without SDL, these options (and -no-quit) print an error message
and exit qemu.
In case QEMU is compiled with SDL support, the three aforementioned options
still do not make sense with other display types. This patch addresses that
issue by printing a warning. I have chosen not to exit QEMU afterwards because
having the option is not harmful and before this patch it would be ignored
anyway.
By delaying the sanity check from compile-time with some ifdefs to run-time,
-no-quit is now also properly supported when compiling without SDL.

slightly different now: Instead of replacing the data directory the
path specified will be appended to the data directory list. So when
specifiying -L multiple times all directories specified will be checked,
in the order they are specified on the command line, instead of just the
last one.
Additionally the default paths are always appended to the directory
data list. This allows to specify a incomplete directory (such as the
seabios out/ directory) via -L. Anything not found there will be loaded
from the default paths, so you don't have to create a symlink farm for
all the rom blobs.
For trouble-shooting a tracepoint has been added, logging which blob
has been loaded from which location.

This patch adds support for cancelling an executing TPM command.
In Linux for example a user can cancel a command through the TPM's
sysfs 'cancel' entry using
echo "1" > /sysfs/class/misc/tpm0/device/cancel
This patch propagates the cancellation of a command inside a VM
to the host TPM's sysfs entry.
It also uses the possibility to cancel the command before QEMU VM
shutdown or reboot, which helps in preventing QEMU from hanging while
waiting for the completion of the command.
To relieve higher layers or users from having to determine the TPM's
cancel sysfs entry, the driver searches for the entry in well known
locations.

This patch adds support for TPM command line options.
The command line options supported here are
./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
-device tpm-tis,tpmdev=<id>,id=<other id>
and
./qemu-... -tpmdev help
where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').
Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.
Monitor support for 'info tpm' has been added. It for example prints the
following:
(qemu) info tpm
TPM devices:
tpm0: model=tpm-tis
\ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

qdev_free and qbus_free have to do unparent+unref, because nobody else
drops the initial reference (the one included by object_initialize)
before them.
For device_init_func and do_device_add, this is trivially correct,
since the DeviceState goes out of scope.
For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky.
What we are doing here is just assuming that the caller knows what it's
doing, and won't call qdev_free/qbus_free while the device is still there.
This is a pretty reasonable assumption and (behind the scenes) is also
what GObject/GTK does. GTK actually has a "floating reference" that
goes away as soon as the caller does gtk_container_add or something
like that, but in the end qbus_init and qdev_try_create are already
adding the new object to its qdev parent! So in the end the two solutions
are the same.

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).

Curses display requires stdin/out to stay on the terminal,
so -daemonize makes no sense in this case. Instead of
leaving display uninitialized like is done since 995ee2bf46,
explicitly detect this case earlier and error out.
-nographic can actually be used with -daemonize, by redirecting
everything to a null device, but the problem is that according
to documentation and historical behavour, -nographic redirects
guest ports to stdin/out, which, again, makes no sense in case
of -daemonize. Since -nographic is a legacy option, don't bother
fixing this case (to allow -nographic and -daemonize by redirecting
guest ports to null instead of stdin/out in this case), but disallow
it completely instead, to stop garbling host terminal.
If no display display needed and user wants to use -nographic,
the right way to go is to use
-serial null -parallel null -monitor none -display none -vga none
instead of -nographic.
Also prevent the same issue -- it was possible to get garbled
host tty after
-nographic -daemonize
and it is still possible to have it by using
-serial stdio -daemonize
Fix this by disallowing opening stdio chardev when -daemonize

There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.
This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)
To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.
I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.
