In one of the recent reworks to the XICS code, a bug was introduced where
we use the wrong sense and allocate level interrupts instead of message
interrupts for PCI MSIs. This patch fixes it.

QEMU allocates a map enough for 4k pages. However the system page size
can be 64K (for example on POWER) and the host kernel uses only a small
part of it as one big stores a dirty flag for 16 pages 4K each,
the hpratio variable stores this ratio and
the kvm_get_dirty_pages_log_range function handles it correctly.
However kvm_get_dirty_pages_log_range still goes beyond the data
provided by the host kernel which is not correct. It does not cause
errors at the moment as the whole bitmap is zeroed before doing KVM ioctl.
The patch reduces number of iterations over the map.

This patch fixes bug 1031698 :
https://bugs.launchpad.net/qemu/+bug/1031698
If we look at the (truncated) translation of the conditional branch
instruction in the test submitted in the bug post, the call to the
exception helper is missing in the "bne-false" chunk of translated
code :
IN:
bne- 0x1800278
OUT:
0xb544236d: jne 0xb5442396
0xb5442373: mov %ebp,(%esp)
0xb5442376: mov $0x44,%ebx
0xb544237b: mov %ebx,0x4(%esp)
0xb544237f: mov $0x1800278,%ebx
0xb5442384: mov %ebx,0x25c(%ebp)
0xb544238a: call 0x827475a
^^^^^^^^^^^^^^^^^^
0xb5442396: mov %ebp,(%esp)
0xb5442399: mov $0x44,%ebx
0xb544239e: mov %ebx,0x4(%esp)
0xb54423a2: mov $0x1800270,%ebx
0xb54423a7: mov %ebx,0x25c(%ebp)
Indeed, gen_exception(ctx, excp) called by gen_goto_tb (called by
gen_bcond) changes ctx->exception's value to excp's :
gen_bcond()
{
gen_goto_tb(ctx, 0, ctx->nip + li - 4);
/* ctx->exception value is POWERPC_EXCP_BRANCH */
gen_goto_tb(ctx, 1, ctx->nip);
/* ctx->exception now value is POWERPC_EXCP_TRACE */
}
Making the following gen_goto_tb()'s test false during the second call :
if ((ctx->singlestep_enabled &
(CPU_BRANCH_STEP | CPU_SINGLE_STEP)) &&
ctx->exception == POWERPC_EXCP_BRANCH /* false...*/) {
target_ulong tmp = ctx->nip;
ctx->nip = dest;
/* ... and this is the missing call */
gen_exception(ctx, POWERPC_EXCP_TRACE);
ctx->nip = tmp;
}
So the patch simply adds the missing matching case, fixing our problem.

When adding the Haswell CPU model, I intended to make it a superset of the

RDTSCP features from the feature list by mistake. This patch adds the
missing SEP and RDTSCP features (that are present on SandyBridge) to
Haswell.

These versions of GCC require insane (>2GB) amounts of memory to compile
translate.o. As a countermeasure, disable the culprit optimization pass.
This should fix the buildbot failure for default_x86_64_fedora16. Anyway
this is a good thing to do because people will try to compile 1.3 with
less than 2GB of memory and complain.

This bug occurs when the SET flag of Register B is enabled. When an RTC
data register (i.e. any of the ten time/calender CMOS bytes) is set, the
data is (as expected) correctly stored in the cmos_data array. However,
since the SET flag is enabled, the function rtc_set_time is not invoked.
As a result, the field base_rtc in RTCState remains uninitialized. This
causes a problem on subsequent writes which can end up overwriting data.
To see this, consider writing data to Register A after having written
data to any of the RTC data registers; the following figure illustrates
the call stack for the Register A write operation:
+- cmos_io_port_write
+-- check_update_timer
+---- get_next_alarm
+------ rtc_update_time
In rtc_update_time, get_guest_rtc calculates the wrong time and
overwrites the previously written RTC data register values.

g_assert_cmpint is not available on glib 2.12, which is the minimum
version required to build QEMU (we only require 2.16 to run tests,
since that is the first version including GTester). Do not use it
in hardware models, use a normal assertion instead.
This fixes the buildbot failure for default_x86_64_rhel5.

The cancellation test is failing on the buildbots. While the failure
merits a little more investigation to understand what is going on,
the logs show that the failure is not impacting the coverage
provided by the test. Hence, loosen a bit the assertions in a
way that should let the test proceed and hopefully pass.

Popping an elem from the vq just to find out its length causes problems

visit_type_size() requires either visitor->type_size() or
visitor_uint64() to be implemented, otherwise a NULL function pointer is
invoked.
It is possible to trigger this crash as follows:
$ qemu-system-x86_64 -netdev tap,sndbuf=0,id=netdev0 \
-device virtio-blk-pci,netdev=netdev0
The 'sndbuf' option has type "size".

Commit 094b287f0b accidentally broke the "-usb" command line
option, so it would have no effect if the user had not specified
any machine options at that point. (the return value from
'qemu_opts_find(qemu_find_opts("machine"), 0);' is NULL if there
are no user specified options, so it is only to be used for
looking up an option, not when trying to set one.) Similarly,
would '-usbdevice' no longer cause USB to default to enabled.
Fix this regression by using the same style of code for forcing
the usb=on machine option that we use for other aliases such as
'-enable-kvm'.

Store in the object the freeing function that will be used at deletion
time. This makes it possible to use object_delete on statically-allocated
(embedded) objects. Dually, it makes it possible to use object_unparent

might extend until after the call to object_delete.

The reference count for embedded objects is always one too low, because
object_initialize_with_type returns with zero references to the object.
This causes premature finalization of the object (or an assertion failure)
after calling object_ref to add an extra reference and object_unref to
remove it.
The fix is to move the initial object_ref call from object_new_with_type
to object_initialize_with_type.

Commit 0d93692 (qdev: Convert busses to QEMU Object Model, 2012-05-02)
removed a check on the type of the bus where a SCSI disk is hotplugged.
However, hot-plugging to the wrong kind of device now causes a crash
due to either a NULL pointer dereference (avoided by the previous patch)
or a failed QOM cast.
Instead, in this case we need to use object_dynamic_cast and check for
the result, similar to what was done before that commit.

Move ioapic_init() from pc_piix.c to pc.c, to make it a common function.
Rename ioapic_init() -> ioapic_init_gsi().
Move to pc.h so q35 can use them as well.

Factor out pc nic initialization.
This simplifies the pc initialization and will reduce the code
duplication of q35 pc initialization.

Instead report them as successfully completed directly on submission, this
has 2 advantages:
1) This matches the timing of interrupt output packets on real hardware,
with the previous async handling, if an ep has an interval of say 500 ms,
then there would be 500+ ms between the submission and the guest seeing the
completion, as we wont do the write back until the qh gets polled again. And
in the mean time the guest may very well have timed out, as the guest can
reasonable expect a much quicker completion.
2) This fixes interrupt output packets potentially getting send twice
surrounding a migration. As we delay the writeback to guest memory until
the qh gets polled again, there is a window between completion and writeback
where migration can happen, in this case the destination will not know
about the completion, and it will execute the packet *again*
But it does also come with a disadvantage:
1) If the actual interrupt out to the real usb device fails, there is no
way to report this back to the guest.
This patch assumes however that interrupt outs in practice never fail, as
they are only used by specialized drivers, which are unlikely to issue illegal
requests (unlike general class drivers which often issue requests which some
devices don't implement). And that thus the advantages outway the disadvantage.

When we've no data to return from the interrupt endpoint, return NAK rather
then a 0 length packet.

I noticed this while making all devices with interrupt endpoints properly
do wakeup. While at it also add wakeup support.
Note that I've not tested this, but returning STALL for an interrupt ep
which has no data is cleary the wrong thing to do.
