That would be unsafe in case a rule other than the current one
is removed while the coroutine has yielded.
Keep FOREACH_SAFE because suspend_request deletes the current rule.
After this patch, *all* matching rules are deleted before suspending
the coroutine, rather than just one.
This doesn't affe
When qemu_coroutine_enter is executed in a loop
(even QEMU_FOREACH_SAFE), the new routine can modify the list,
for example removing an element, causing problem when control

For IEEE functions, we can reuse the softfloat implementations. For the
other functions, implement it generically for 32bit/64bit/128bit -

Hi all!
I'd like to share and discuss some plans on Qemu backup interface I have.
(actually, most of this I've presented on KVM Forum long ago.. But now I'm a
lot closer to realization:)
I'd start with a reminder about image fleecing:
We have image fleecing scheme to export point-in-time sta

Few changes to speed up builds, removing 330 objects.
RFC because of:
- accel hax/whpx changes
- sysemu/memory_mapping target_ulong -> hwaddr
which i'm not sure of the impacts.

KVM dirty ring is a new interface to pass over dirty bits from kernel to the
userspace. Instead of using a bitmap for each memory region, the dirty ring
contains an array of dirtied GPAs to fetch (in the form of offset in slots).
For each vcpu there will be one dirty ring that bin
qmp_memsave() and qmp_pmemsave() call cpu_memory_rw_debug()
and cpu_physical_memory_read(), which are target specific
prototypes. To be able to build softmmu/cpus.c once for
all targets, extract the QMP commands handlers to a new
file which will be built per target.

Various softmmu objects aren't target specific. Move them
to the generic softmmu source set.
For our 31 softmmu targets, this is in total 330 objects
less to build!

KVM_CAP_MANUAL_DIRTY_LOG_PROTECT2 is for KVM_CLEAR_DIRTY_LOG, which is only
useful for KVM_GET_DIRTY_LOG. Skip enabling it for kvm dirty ring.
More importantly, KVM_DIRTY_LOG_INITIALLY_SET will not wr-protect all the pages
initially, which is against how kvm dirty ring is used -
kvm_on_sigbus() and kvm_on_sigbus_vcpu() prototypes don't have
to be target specific. Remove this limitation to be able to build

Add a parameter for dirty gfn count for dirty rings. If zero, dirty ring is
disabled. Otherwise dirty ring will be enabled with the per-vcpu gfn count as
specified. If dirty ring cannot be enabled due to unsupported kernel or
illegal parameter, it'll fallback to dirty logging.
target_ulong is target-specific, while hwaddr isn't.
memory_mapping_list_add_merge_sorted() uses hwaddr arguments
anyway, so use the hwaddr type for MemoryMapping::virt_addr.
Remove the unnecessary "exec/cpu-defs.h" target-speficic header
from "memory_mapping.h" and use the target-agnostic "hw/co
