2012-10-30target-i386: Initialize APIC at CPU levelIgor Mammedov
(L)APIC is a part of cpu [1] so move APIC initialization inside of x86_cpu object. Since cpu_model and override flags currently specify whether APIC should be created or not, APIC creation&initialization is moved into x86_cpu_apic_init() which is called from x86_cpu_realize(). [1] - all x86 cpus have integrated APIC if we overlook existence of i486, and it's more convenient to model after majority of them.

2012-10-30configure: use -Wwombat to test whether gcc recognizes -Wno-wombatPeter Maydell
gcc will silently accept unrecognized -Wno-wombat warning suppression options (it only mentions them if it has to print a compiler warning for some other reason). Since we already run a check for whether gcc recognizes the warning options we use, we can easily make this use the positive sense of the option when checking for support for the suppression option. This doesn't have any effect except that it avoids gcc emitting extra messages about unrecognized command line options when it is printing other warning messages.

2012-10-29memory: fix rendering of a region obscured by anotherAvi Kivity
The memory core drops regions that are hidden by another region (for example, during BAR sizing), but it doesn't do so correctly if the lower address of the existing range is below the lower address of the new range. Example (qemu-system-mips -M malta -kernel vmlinux-2.6.32-5-4kc-malta -append "console=ttyS0" -nographic -vga cirrus): Existing range: 10000000-107fffff New range: 100a0000-100bffff Correct behaviour: drop new range Incorrect behaviour: add new range Fix by taking this case into account (previously we only considered equal lower boundaries).

2012-10-29s390: sclp ascii console supportHeinz Graalfs
This code adds console support by implementing SCLP's ASCII Console Data event. This is the same console as LPARs ASCII console or z/VMs sysascii. The console can be specified manually with something like -chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0 Newer kernels will autodetect that console and prefer that over virtio console. When data is received from the character layer it creates a service interrupt to trigger a Read Event Data command from the guest that will pick up the received character byte-stream. When characters are echo'ed by the linux guest a Write Event Data occurs which is forwarded by the Event Facility to the console that supports a corresponding mask value. Console resizing is not supported. The character layer byte-stream is buffered using a fixed size iov buffer.

2012-10-29s390: sclp signal quiesce supportHeinz Graalfs
This implements the sclp signal quiesce event via the SCLP Event Facility. This allows to gracefully shutdown a guest by using system_powerdown notifiers. It creates a service interrupt that will trigger a Read Event Data command from the guest. This code will then add an event that is interpreted by linux guests as ctrl-alt-del.

2012-10-29s390: sclp event supportHeinz Graalfs
Several SCLP features are considered to be events. Those events don't provide SCLP commands on their own, instead they are all based on Read Event Data, Write Event Data, Write Event Mask and the service interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via system_powerdown) and the ASCII console. Further down the road the sclp line mode console and configuration change events (e.g. cpu hotplug) can be implemented.

This adds a more generic infrastructure for handling Service-Call requests on s390. Currently we only support a small subset of Read SCP Info directly in target-s390x. This patch provides the base infrastructure for supporting more commands and moves Read SCP Info. In the future we could add additional commands for hotplug, call home and event handling.

2012-10-29s390: use sync regs for register transferChristian Borntraeger
Newer kernels provide the guest registers in kvm_run. Lets use those if available (i.e. the capability is set). This avoids ioctls on cpu_synchronize_state making intercepts faster. In addition, we have now the prefix register, the access registers the control registers up to date. This helps in certain cases, e.g. for resolving kernel module addresses with gdb on a guest. On return, we update the registers according to the level statement, i.e. we put all registers for KVM_PUT_FULL_STATE and _RESET_STATE.

2012-10-29s390/kvm_stat: correct sys_perf_event_open syscall numberHeinz Graalfs
Correct sys_perf_event_open syscall number for s390 architecture - the hardcoded syscall number 298 is for x86 but should be different for other architectures. In case we figure out via /proc/cpuinfo that we are running on s390 the appropriate syscall number is used from map syscall_numbers; other architectures can extend this.

2012-10-29pci: avoid destroying bridge address space windows in a transactionAvi Kivity
Calling memory_region_destroy() in a transaction is illegal (and aborts), as until the transaction is committed, the region remains live. Fix by moving destruction until after the transaction commits. This requires having an extra set of regions, so the new and old regions can coexist.
