2018-12-21ppc/xive: introduce the XiveNotifier interfaceCédric Le Goater2-0/+48
The XiveNotifier offers a simple interface, between the XiveSource object and the main interrupt controller of the machine. It will forward event notifications to the XIVE Interrupt Virtualization Routing Engine (IVRE).

2018-12-21ppc/xive: add support for the LSI interrupt sourcesCédric Le Goater2-7/+79
The 'sent' status of the LSI interrupt source is modeled with the 'P' bit of the ESB and the assertion status of the source is maintained with an extra bit under the main XiveSource object. The type of the source is stored in the same array for practical reasons. Signed-off-by: Cédric Le Goater <clg@kaod.org> [dwg: Fix style nit] Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-12-21ppc/xive: introduce a XIVE interrupt source modelCédric Le Goater4-0/+644
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.

2018-12-21e500: simplify IRQ wiringGreg Kurz1-10/+8
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) as recommended in HACKING. Signed-off-by: Greg Kurz <groug@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2018-12-21target/ppc: tcg: Implement addex instructionSuraj Jitindar Singh2-27/+35
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).

Laurent Vivier reported off by one with maximum number of NUMA nodes provided by qemu-kvm being less by one than required according to description of "ibm,max-associativity-domains" property in LoPAPR.

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.

2018-12-18qmp hmp: Make system_wakeup check wake-up support and run stateDaniel Henrique Barboza10-14/+33
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) Reported-by: Balamuruhan S <bala24@linux.vnet.ibm.com> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> Message-Id: <20181205194701.17836-4-danielhb413@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Acked-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

2018-12-18qmp: query-current-machine with wakeup-suspend-supportDaniel Henrique Barboza5-0/+55
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.

2018-12-18qmp: Split ShutdownCause host-qmp into quit and system-resetDominik Csapak23-81/+83
It is interesting to know whether the shutdown cause was 'quit' or 'reset', especially when using "--no-reboot". In that case, a management layer can now determine if the guest wanted a reboot or shutdown, and can act accordingly. Changes the output of the reason in the iotests from 'host-qmp' to 'host-qmp-quit'. This does not break compatibility because the field was introduced in the same version.

2018-12-18qmp: Add reason to SHUTDOWN and RESET eventsDominik Csapak23-79/+95
This makes it possible to determine what the exact reason was for a RESET or a SHUTDOWN. A management layer might need the specific reason of those events to determine which cleanups or other actions it needs to do. This patch also updates the iotests to the new expected output that includes the reason.

2018-12-17tests/acpi-utils: Drop dependence on global_qtestEric Blake4-92/+96
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).

2018-12-17ivshmem-test: Drop dependence on global_qtestEric Blake1-17/+1
Managing parallel connections to two different monitors via the implicit global_qtest makes it hard to copy-and-paste code to tests that are not aware of the implicit state. Since we have already fixed qpci to avoid global_qtest, we can now simplify by not using global_qtest anywhere in ivshmem-test. We can assert that the conversion is correct by checking that global_qtest remains NULL throughout the test (a later patch that changes global_qtest to not be a public global variable will drop the assertions).
