ecba19935a hw/timer: Revert "hpet: inverse polarity when pin above ISA_NUM_IRQS"
This reverts commit 0d63b2dd31.

This change was originally intended to correct the HPET behavior
in conjunction with Linux, however the behavior that it actually creates
is not compatible with the ioapic.c implementation; it used to be
compatible with KVM's own IOAPIC but it is not anymore.

73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

c04bd47db6 hw/timer: Add ASPEED timer device model
Implement basic ASPEED timer functionality for the AST2400 SoC[1]: Up to
8 timers can independently be configured, enabled, reset and disabled.
Some hardware features are not implemented, namely clock value matching
and pulse generation, but the implementation is enough to boot the Linux
kernel configured with aspeed_defconfig.

d552f675fb i.MX: Add the CLK_IPG_HIGH clock
EPIT, GPT and other i.MX timers are using "abstract" clocks among which
a CLK_IPG_HIGH clock.

On i.MX25 and i.MX31 CLK_IPG and CLK_IPG_HIGH are mapped to the same clock
but on other SOC like i.MX6 they are mapped to distinct clocks.

This patch add the CLK_IPG_HIGH to prepare for SOC where these 2 clocks are
different.

d17008bc29 hw/timer/hpet.c: Avoid signed integer overflow which results in bugs on OSX
Signed integer overflow in C is undefined behaviour, and the compiler
is at liberty to assume it can never happen and optimize accordingly.
In particular, the subtractions in hpet_time_after() and hpet_time_after64()
were causing OSX clang to optimize the code such that it was prone to
hangs and complaints about the main loop stalling (presumably because
we were spending all our time trying to service very high frequency
HPET timer callbacks). The clang sanitizer confirms the UB:

hw/timer/hpet.c:119:26: runtime error: signed integer overflow: -2146967296 - 2147003978 cannot be represented in type 'int'

Fix this by doing the subtraction as an unsigned operation and then
converting to signed for the comparison.

Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

13566fe3e5 timer: rename NSEC_PER_SEC due to Mac OS X header clash
Commit e0cf11f31c ("timer: Use a single
definition of NSEC_PER_SEC for the whole codebase") renamed
NANOSECONDS_PER_SECOND to NSEC_PER_SEC.

On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC.  This causes compiler warnings.

Let's use the old name instead.  It's longer but it doesn't clash.

8a52340cba arm_mptimer: Fix timer shutdown and mode change
The running timer can't be stopped because timer control code just
doesn't handle disabling the timer. Fix it by deleting the timer if
the enable bit is cleared.

The timer won't start periodic ticking if a ONE-SHOT -> PERIODIC mode
change happens after a one-shot tick was completed. Fix it by
re-starting ticking if the timer isn't ticking right now.

To avoid code churning, these two fixes are squashed in one commit.

ae46e23964 mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.

qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST.  However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler.  In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.

To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.

Fix this by ignoring read from the Mode/Command register.

This is CVE-2015-3214.

For subsections we just change:

- Add a needed function to VMStateDescription
- Remove VMStateSubsection (after removal of the needed function
  it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding

8e099d14f5 Generalize QOM publishing of date and time from mc146818rtc.c
The mc146818rtc driver exposes the current RTC date and time via the "date"
property in QOM (which is also aliased to the machine's "rtc-time"
property).  Currently it uses a custom visitor function rtc_get_date to
do this.

This patch introduces new helpers to the QOM core to expose struct tm
valued properties via a getter function, so that this functionality can be
more easily duplicated in other RTC implementations.

The symbol TIMER_MAX used in imx_epit.c and imx_gpt.c

all qemu source files includes qemu-common.h which, in

297a3646c2 qapi: Replace uncommon use of the error API by the common one
We commonly use the error API like this:

    err = NULL;
    foo(..., &err);
    if (err) {
        goto out;
    }
    bar(..., &err);

Every error source is checked separately.  The second function is only
called when the first one succeeds.  Both functions are free to pass
their argument to error_set().  Because error_set() asserts no error
has been set, this effectively means they must not be called with an
error set.

The qapi-generated code uses the error API differently:

    // *errp was initialized to NULL somewhere up the call chain
    frob(..., errp);
    gnat(..., errp);

Errors accumulate in *errp: first error wins, subsequent errors get
dropped.  To make this work, the second function does nothing when
called with an error set.  Requires non-null errp, or else the second
function can't see the first one fail.

This usage has also bled into visitor tests, and two device model
object property getters rtc_get_date() and balloon_stats_get_all().

With the "accumulate" technique, you need fewer error checks in
callers, and buy that with an error check in every callee.  Can be
nice.

However, mixing the two techniques is confusing.  You can't use the
"accumulate" technique with functions designed for the "check
separately" technique.  You can use the "check separately" technique
with functions designed for the "accumulate" technique, but then
error_set() can't catch you setting an error more than once.

Standardize on the "check separately" technique for now, because it's
overwhelmingly prevalent.

acpi,pc,build bug fixes

Here are some bugfixes for 2.0.

A bugfix for acpi for pci bridges, and a build fix for
old systems without pthread_setname_np: both fix regressions
so we definitely want to include them.
HPET fix is not for a regression but looks very safe,
fixes a nasty bug and has been on list for a while.

c36ad13fe9 Don't enable a HPET timer if HPET is disabled
A HPET timer can be started when HPET is not yet
enabled. This will not generate an interrupt
to the guest, but causes problems when HPET is later
enabled.

A timer that is created and expires at least once before
HPET is enabled will have an initialized comparator based
on a hpet_offset of 0 (uninitialized). When HPET is
enabled, hpet_set_timer() is called a second time, which
modifies the timer expiry to a time based on the
difference between current ticks (measured with the
newly initialized hpet_offset) and the timer's
comparator (which was generated before hpet_offset was
initialized). This results in a long period of no HPET
timer ticks.

When this occurs with a CentOS 5.x guest, the guest
may not receive timer interrupts during its narrow
timer check window and panic on boot.

  * 54 bits User timer. For profiling. In this mode, the Run/Stop bit
    controls the timer.

The run/stop bit controls the timer only when it is in "User" mode, but

837d37167d sysbus: Set cannot_instantiate_with_device_add_yet
device_add plugs devices into suitable bus.  For "real" buses, that
actually connects the device.  For sysbus, the connections need to be
made separately, and device_add can't do that.  The device would be
left unconnected, and could not possibly work.

Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.

sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

efec3dd631 qdev: Replace no_user by cannot_instantiate_with_device_add_yet
In an ideal world, machines can be built by wiring devices together
with configuration, not code.  Unfortunately, that's not the world we
live in right now.  We still have quite a few devices that need to be
wired up by code.  If you try to device_add such a device, it'll fail
in sometimes mysterious ways.  If you're lucky, you get an
unmysterious immediate crash.

To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad.  The device model is still omitted from
help, but is available anyway.

Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.

This commit clarifies no_user's purpose.  Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy.  While there, make it
bool.

Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale.  The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.

With that done, the regression fix is hopefully acceptable.

7a10ef51c2 hpet: enable to entitle more irq pins for hpet
Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.

On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.

Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

0d63b2dd31 hpet: inverse polarity when pin above ISA_NUM_IRQS
According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)

We fold the emulation of this inversion inside the hpet logic.

6783ecf144 hw: Avoid use of QOM type name macros in VMStateDescriptions
The name field in a VMStateDescription is part of the migration state
versioning, so changing it will break migration.  It's therefore a
bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup.  For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal
strings.
