Max Filippov 19b7bec4a3 target-xtensa: implement S32NB
S32NB provides the same functionality as S32I with two exceptions.
First, when its operation leaves the processor, the external transaction
is marked Non-Bufferable. Second, it may not be used to write to
Instruction RAM.
In QEMU S32NB is equivalent to S32I.

Max Filippov 68931a4082 target-xtensa: xtfpga: attach FLASH to system IO
XTFPGA FLASH is tied to XTFPGA system IO block. It's not very important
for systems with MMU where system IO block is visible at single
location, but it's important for noMMU systems, where system IO block is
accessible through two separate physical address ranges.

Map XTFPGA FLASH to system IO block and fix offsets used for mapping.
Create and initialize FLASH device with series of qdev_prop_set_* as
that's the preferred interface now. Keep initialization in a separate
function.

David Hildenbrand 1cd4e0f6f0 s390x/cmma: clean up cmma reset
The cmma reset is per VM, so we don't need a cpu object. We can
directly make use of kvm_state, as it is already available when
the reset is called. By moving the cmma reset in our machine reset
function, we can avoid a manual reset handler.

David Hildenbrand 4ab729207f s390x: reset crypto only on clear reset and QEMU reset
Initializing VM crypto in initial cpu reset has multiple problems

1. We call the exact same function #VCPU times, although one time is enough
2. On SIGP initial cpu reset, we exchange the wrapping key while
   other VCPUs are running. Bad!
3. It is simply wrong. According to the Pop, a reset happens only during a
   clear reset.

So, we have to reset the keys
- on modified clear reset
- on load clear (QEMU reset - via machine reset)
- on qemu start (via machine reset)

David Hildenbrand db3b2566e0 s390x: machine reset function with new ipl cpu handling
Current implementation depends on the order of resets getting triggered.

If a cpu reset is triggered after the ipl device reset, the CPU is stopped and
the VM will not run. In fact, that hinders us from converting the ipl device
into a TYPE_DEVICE. Let's change that by manually configuring the ipl cpu
during a system reset, so we have full control and can demangle that code.

Also remove the superflous cpu parameter from s390_update_iplstate on the way.

Instead of using magic values when building the machine check
interruption code, add some defines as by chapter 11-14 in the PoP.

This should make it easier to catch problems like the missing vector
register validity bit ("s390x/kvm: Fix vector validity bit in device
machine checks"), and less hassle should we want to generate machine
checks beyond the channel reports we currently support.

Device hotplugs trigger a crw machine check. All machine checks

This is a band-aid suitable for stable. Long term we should

features in the kernel interrupt handler.

Daniel P. Berrange 10817bf09d coroutine: move into libqemuutil.a library
The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.

The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

Daniel P. Berrange 57cb38b383 osdep: add qemu_fork() wrapper for safely handling signals
When using regular fork() the child process of course inherits
all the parents' signal handlers. If the child then proceeds
to close() any open file descriptors, it may break some of those
registered signal handlers. The child generally does not want to
ever run any of the signal handlers that the parent may have
installed in the short time before it exec's. The parent may also
have blocked various signals which the child process will want
enabled.

This introduces a wrapper qemu_fork() that takes care to sanitize
signal handling across fork. Before forking it blocks all signals
in the parent thread. After fork returns, the parent unblocks the
signals and carries on as usual. The child, however, resets all the
signal handlers back to their defaults before it unblocks signals.
The child process can now exec the binary in a "clean" signal
environment.

Implemented with base64-encoded strings in qga json protocol.
Glib portable GIOChannel is used for data I/O.

Optinal stdin parameter of guest-exec command is now used as
stdin content for spawned subprocess.

If capture-output bool flag is specified, guest-exec redirects out/err
file descriptiors internally to pipes and collects subprocess
output.

Guest-exe-status is modified to return this collected data to requestor
in base64 encoding.

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).  Same Coccinelle semantic patch as in commit b45c03f.

Michael Roth fafcaf1d74 build: qemu-ga: add 'qemu-ga' build target for w32
Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.

Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:

  make qemu-ga.exe

or:

  make msi

To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.

To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.

An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.

To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`
