According to the PoP, a restart irq has to be delivered "without first honoring any other pending interruptions", if a cpu is in the STOPPED state. While it is hard to implement this case in kvm, it can easily be handled in qemu.

This patch adds handling code for the following SIGP orders: - SIGP SET ARCHITECTURE - SIGP SET PREFIX - SIGP STOP - SIGP STOP AND STORE STATUS - SIGP STORE STATUS AT ADDRESS SIGP STOP (AND STORE STATUS) are the only orders that can stay pending forever (and may only be interrupted by resets), so special care has to be taken about them. Their status also has to be tracked within QEMU. This patch takes care of migrating this status (e.g. if migration happens during a SIGP STOP). Due to the BQL, only one VCPU is currently able to execute SIGP handlers at a time. According to the PoP, BUSY should be returned if another SIGP order is currently being executed on a VCPU. This can only be implemented when the BQL does not protect all handlers. For now, all SIGP orders on all VCPUs will be serialized, which will be okay for the first shot.

Whenever a sigp order is to be executed by a target vcpu, we use run_on_cpu(). As we have only one pointer to pass all data to these sigp handlers, let's introduce the struct sigp_info and use it as a transport container. All orders targeting a single vcpu are now dispatched from a separate handler. The destination vcpu is only valid for these orders and must not be checked for SIGP SET ARCHITECTURE. The sigp_info is filled with life in this new handler and used to pass the information about the sigp order to the existing handlers. The cc is set within these handlers. Rename sigp_cpu_start() and sigp_cpu_restart() on the way to match the SIGP order names (in order to avoid touching affected lines several times).

The emulation for EEH RTAS requests from guest isn't covered by QEMU yet and the patch implements them. The patch defines constants used by EEH RTAS calls and adds callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset, eeh_configure}, which are going to be used as follows: * RTAS calls are received in spapr_pci.c, sanity check is done there. * RTAS handlers handle what they can. If there is something it cannot handle and the corresponding sPAPRPHBClass callback is defined, it is called. * Those callbacks are only implemented for VFIO now. They do ioctl() to the IOMMU container fd to complete the calls. Error codes from that ioctl() are transferred back to the guest.

5b79b1ca "target-ppc: Create versionless CPU class per family if KVM" added a dynamic CPU class registration with the name of the CPU family which QEMU is running on. For example, this allowed specifying "-cpu POWER7" on every version of POWER7 machine, not just the one which POWER7 was an alias of. I.e. before 5b79b1ca, "-cpu POWER7" would not work on real POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8. However that patch broke POWER5+ support as POWER5+ CPU uses the same name as the CPU class so dynamic registering of the POWER5+ class failed. This redefines POWER5+ server CPUs by adding a version to them and adding an alias for TCG case. KVM will use dynamically registered CPUs. While we are here, do the same for 970 CPU.

This patch adds basic support for the VTB. PowerISA: The Virtual Time Base (VTB) is a 64-bit incrementing counter. Virtual Time Base increments at the same rate as the Time Base until its value becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when this occurs. The operation of the Virtual Time Base has the following additional properties. 1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of the Virtual Time Base. 2. Copying the contents of a GPR to the Virtual Time Base replaces the contents of the Virtual Time Base with the contents of the GPR.

The VGA device model now supports having the framebuffer in either endian, and can be switched between these by the guest via a register in the qext region. However, in some cases (e.g. LE OS on the pseries machine) we have existing guest that don't know about the endian switch register, but other parts of the qemu code have better information to set a default endianness than the VGA code does of itself. In order to allow them to set a correct default endianness in these cases, without breaking abstraction walls, this patch exposes the VGA framebuffer endianness via a writable QOM property.

We call try_create_xics() to create a "xics-kvm". If it fails, we call it again to fall back to plain "xics". try_create_xics() uses qdev_init(). qdev_init()'s error handling has an unwanted side effect: it calls qerror_report_err(), which prints to stderr. Looks like an error, but isn't. In QMP context, it would stash the error in the monitor instead, making the QMP command fail. Fortunately, it's only called from board initialization, never in QMP context. Clean up by cutting out the qdev_init() middle-man: set property "realized" directly. While there, improve the error message when we can't satisfy an explicit user request for "xics-kvm", and exit(1) instead of abort(). Simplify the abort when we can't create "xics".

The initial creation of the PAPR RTC qdev class left a wart - the rtc's offset was left in the sPAPREnvironment structure, accessed via a global. This patch moves it into the RTC device's own state structure, were it belongs. This requires a small change to the migration stream format. In order to handle incoming streams from older versions, we also need to retain the rtc_offset field in the sPAPREnvironment structure, so that it can be loaded into via the vmsd, then pushed into the RTC device. Since we're changing the migration format, this also takes the opportunity to: * Change the rtc offset from a value in seconds to a value in nanoseconds, allowing nanosecond offsets between host and guest rtc time, if desired. * Remove both the already unused "next_irq" field and now unused "rtc_offset" field from the new version of the spapr migration stream Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NAlexander Graf <agraf@suse.de>
