To complete the event routing, the IVRE sub-engine uses a second table
containing Event Notification Descriptor (END) structures.
An END specifies on which Event Queue (EQ) the event notification
data, defined in the associated EAS, should be posted when an
exception occurs. It also defines which Notification Virtual Target
(NVT) should be notified.
The Event Queue is a memory page provided by the O/S defining a
circular buffer, one per server and priority couple, containing Event
Queue entries. These are 4 bytes long, the first bit being a
'generation' bit and the 31 following bits the END Data field. They
are pulled by the O/S when the exception occurs.
The END Data field is a way to set an invariant logical event source
number for an IRQ. On sPAPR machines, it is set with the
H_INT_SET_SOURCE_CONFIG hcall when the EISN flag is used.

The XiveRouter models the second sub-engine of the XIVE architecture :
the Interrupt Virtualization Routing Engine (IVRE).
The IVRE handles event notifications of the IVSE and performs the
interrupt routing process. For this purpose, it uses a set of tables
stored in system memory, the first of which being the Event Assignment
Structure (EAS) table.
The EAT associates an interrupt source number with an Event Notification
Descriptor (END) which will be used in a second phase of the routing
process to identify a Notification Virtual Target.
The XiveRouter is an abstract class which needs to be inherited from
to define a storage for the EAT, and other upcoming tables.

The first sub-engine of the overall XIVE architecture is the Interrupt
Virtualization Source Engine (IVSE). An IVSE can be integrated into
another logic, like in a PCI PHB or in the main interrupt controller
to manage IPIs.
Each IVSE instance is associated with an Event State Buffer (ESB) that
contains a two bit state entry for each possible event source. When an
event is signaled to the IVSE, by MMIO or some other means, the
associated interrupt state bits are fetched from the ESB and
modified. Depending on the resulting ESB state, the event is forwarded
to the IVRE sub-engine of the controller doing the routing.
Each supported ESB entry is associated with either a single or a
even/odd pair of pages which provides commands to manage the source:
to EOI, to turn off the source for instance.
On a sPAPR machine, the O/S will obtain the page address of the ESB
entry associated with a source and its characteristic using the
H_INT_GET_SOURCE_INFO hcall. On PowerNV, a similar OPAL call is used.
The xive_source_notify() routine is in charge forwarding the source
event notification to the routing engine. It will be filled later on.

The OpenPIC have 5 outputs per connected CPU. The machine init code hence
needs a bi-dimensional array (smp_cpu lines, 5 columns) to wire up the irqs
between the PIC and the CPUs.
The current code first allocates an array of smp_cpus pointers to qemu_irq
type, then it allocates another array of smp_cpus * 5 qemu_irq and fills the
first array with pointers to each line of the second array. This is rather
convoluted.
Simplify the logic by introducing a structured type that describes all the
OpenPIC outputs for a single CPU, ie, fixed size of 5 qemu_irq, and only
allocate a smp_cpu sized array of those.
This also allows to use g_new(T, n) instead of g_malloc(sizeof(T) * n)

Implement the addex instruction introduced in ISA V3.00 in qemu tcg.
The add extended using alternate carry bit (addex) instruction performs
the same operation as the add extended (adde) instruction, but using the
overflow (ov) field in the fixed point exception register (xer) as the
carry in and out instead of the carry (ca) field.
The instruction has a Z23-form, not an XO form, as follows:
------------------------------------------------------------------
| 31 | RT | RA | RB | CY | 170 | 0 |
------------------------------------------------------------------
0 6 11 16 21 23 31 32
However since the only valid form of the instruction defined so far is
CY = 0, we can treat this like an XO form instruction.
There is no dot form (addex.) of the instruction and the summary overflow
(so) bit in the xer is not modified by this instruction.
For simplicity we reuse the gen_op_arith_add function and add a function
argument to specify where the carry in input should come from and the
carry out output be stored (note must be the same location).

From David Gibson:
------------------
Qemu makes a distinction between "non NUMA" (nb_numa_nodes == 0) and
"NUMA with one node" (nb_numa_nodes == 1). But from a PAPR guests's
point of view these are equivalent. I don't want to present two
different cases to the guest when we don't need to, so even though the
guest can handle it, I'd prefer we put a '1' here for both the
nb_numa_nodes == 0 and nb_numa_nodes == 1 case.
This consolidates everything discussed previously on mailing list.

The qmp/hmp command 'system_wakeup' is simply a direct call to
'qemu_system_wakeup_request' from vl.c. This function verifies if
runstate is SUSPENDED and if the wake up reason is valid before
proceeding. However, no error or warning is thrown if any of those
pre-requirements isn't met. There is no way for the caller to
differentiate between a successful wakeup or an error state caused
when trying to wake up a guest that wasn't suspended.
This means that system_wakeup is silently failing, which can be
considered a bug. Adding error handling isn't an API break in this
case - applications that didn't check the result will remain broken,
the ones that check it will have a chance to deal with it.
Adding to that, the commit before previous created a new QMP API called
query-current-machine, with a new flag called wakeup-suspend-support,
that indicates if the guest has the capability of waking up from suspended
state. Although such guest will never reach SUSPENDED state and erroring
it out in this scenario would suffice, it is more informative for the user
to differentiate between a failure because the guest isn't suspended versus
a failure because the guest does not have support for wake up at all.
All this considered, this patch changes qmp_system_wakeup to check if
the guest is capable of waking up from suspend, and if it is suspended.
After this patch, this is the output of system_wakeup in a guest that
does not have wake-up from suspend support (ppc64):
(qemu) system_wakeup
wake-up from suspend is not supported by this guest
(qemu)
And this is the output of system_wakeup in a x86 guest that has the
support but isn't suspended:
(qemu) system_wakeup
Unable to wake up: guest is not in suspended state
(qemu)

When issuing the qmp/hmp 'system_wakeup' command, what happens in a
nutshell is:
- qmp_system_wakeup_request set runstate to RUNNING, sets a wakeup_reason
and notify the event
- in the main_loop, all vcpus are paused, a system reset is issued, all
subscribers of wakeup_notifiers receives a notification, vcpus are then
resumed and the wake up QAPI event is fired
Note that this procedure alone doesn't ensure that the guest will awake
from SUSPENDED state - the subscribers of the wake up event must take
action to resume the guest, otherwise the guest will simply reboot. At
this moment, only the ACPI machines via acpi_pm1_cnt_init and xen_hvm_init
have wake-up from suspend support.
However, only the presence of 'system_wakeup' is required for QGA to
support 'guest-suspend-ram' and 'guest-suspend-hybrid' at this moment.
This means that the user/management will expect to suspend the guest using
one of those suspend commands and then resume execution using system_wakeup,
regardless of the support offered in system_wakeup in the first place.
This patch creates a new API called query-current-machine [1], that holds
a new flag called 'wakeup-suspend-support' that indicates if the guest
supports wake up from suspend via system_wakeup. The machine is considered
to implement wake-up support if a call to a new 'qemu_register_wakeup_support'
is made during its init, as it is now being done inside acpi_pm1_cnt_init
and xen_hvm_init. This allows for any other machine type to declare wake-up
support regardless of ACPI state or wakeup_notifiers subscription, making easier
for newer implementations that might have their own mechanisms in the future.
This is the expected output of query-current-machine when running a x86
guest:
{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": true}}
Running the same x86 guest, but with the --no-acpi option:
{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": false}}
This is the output when running a pseries guest:
{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": false}}
With this extra tool, management can avoid situations where a guest
that does not have proper suspend/wake capabilities ends up in
inconsistent state (e.g.
https://github.com/open-power-host-os/qemu/issues/31).
[1] the decision of creating the query-current-machine API is based
on discussions in the QEMU mailing list where it was decided that
query-target wasn't a proper place to store the wake-up flag, neither
was query-machines because this isn't a static property of the
machine object. This new API can then be used to store other
dynamic machine properties that are scattered around the code
ATM. More info at:

[thuth: Fixed conflicts with additional "qts" parameter]
Signed-off-by: Thomas Huth <thuth@redhat.com>
There's no point in waiting 5 full minutes when there will be
no more output. Compute timeout based on elapsed wall clock
time instead of N * delays, as the delay is a minimum sleep time.

[thuth: Replaced global_qtest with local qts variable]
Signed-off-by: Thomas Huth <thuth@redhat.com>
global_qtest is not really required here, since boot_sector_test()
is already independent from that global variable.

global_qtest is only needed here for one readl(). Let's replace it
with qtest_readl() and we can remove the global_qtest variable here.

Apart from using qmp() in one spot, this test does not have any
dependencies to the global_qtest variable, so we can simply get
rid of it here by replacing the qmp() with qtest_qmp().

Apart from using qmp() in the qmp_discard_response() macro, these
tests do not have any dependencies to the global_qtest variable,
so we can simply get rid of it here by replacing the qmp() with
qtest_qmp() in the macro.

The test does not use any of the functions that require global_qtest,
so we can simply get rid of this global variable here.

We want to get rid of global_qtest in the long run, thus do not
use the wrappers like inb() and outb() here anymore.

The biggest part has already been done in the previous patch, we now
only have to replace some few qmp() and readb() calls with the
corresponding qtest_*() functions to get there.

As a general rule, we prefer avoiding implicit global state
because it makes code harder to safely copy and paste without
thinking about the global state. Adjust the helper code to
use explicit state instead, and update all callers.
bios-tables-test no longer depends on global_qtest, now that it
passes explicit state through the testsuite data; an assert
proves this fact (although we will get rid of it later, once
global_qtest is gone).
