integrator: fix Linux boot failure by emulating dbg region

Commit 9b8c69243 (since reverted) broke the ability to boot the kernel
as the value returned by unassigned_mem_read returned non-zero and left
the kernel looping forever waiting for it to change (see...

Merge remote-tracking branch 'bonzini/iommu-for-anthony' into staging

  1. By Paolo Bonzini (10) and others
  2. Via Paolo Bonzini
    • bonzini/iommu-for-anthony:
      exec: remove qemu_safe_ram_ptr
      icount: make it thread-safe
      icount: document (future) locking rules for icount...

timer: add timer_mod_anticipate and timer_mod_anticipate_ns

These let a user anticipate the deadline of a timer, atomically with
other sites that call the function. This helps avoiding complicated
lock hierarchies.

timer: make qemu_clock_enable sync between disable and timer's cb

After disabling the QemuClock, we should make sure that no QemuTimers
are still in flight. To implement that with light overhead, we resort
to QemuEvent. The caller of disabling will wait on QemuEvent of each...

qemu-thread: add QemuEvent

This emulates Win32 manual-reset events using futexes or conditional
variables. Typical ways to use them are with multi-producer,
single-consumer data structures, to test for a complex condition whose
elements come from different threads:...

timer: protect timers_state's clock with seqlock

QEMU_CLOCK_VIRTUAL may be read outside BQL. This will make its
foundation, i.e. cpu_clock_offset exposed to race condition.
Using private lock to protect it.

After this patch, reading QEMU_CLOCK_VIRTUAL is thread safe...

portio: Allow to mark portio lists as coalesced MMIO flushing

This will enable us to remove all remaining explicit calls of
qemu_flush_coalesced_mmio_buffer in IO handlers.

seqlock: introduce read-write seqlock

Seqlock implementation for QEMU. Usage idiom

reader:
do {
start = seqlock_read_begin(&sl);
...
} while (seqlock_read_retry(&sl, start));

writer:
seqlock_write_lock(&sl);
...

spice: fix multihead support

This patch fixes spice display initialization to handle
multihead properly.

spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not. It also
manages display channel ids.

exec: Fix prototype of phys_mem_set_alloc and related functions

phys_mem_alloc and its assigned values qemu_anon_ram_alloc and
legacy_s390_alloc must have identical argument lists.

legacy_s390_alloc uses the size parameter to call mmap, so size_t is
good enough for all of them....
