* s390x/gdb: generate target.xml and handle fp/ac as coprocessorsDavid Hildenbrand2014-09-014-60/+76
| | | | | | | | | | | | | | | | | This patch reduces the core registers to the psw and the general purpose registers. The fpc and ac registers are handled as coprocessors registers by gdb. This allows to reuse the feature xml files taken from gdb without further modification and is what other architectures do. The target.xml is now generated and provided to the gdb client. Therefore, the client doesn't have to guess which registers are available at which logical register number.

| | | | | | | | | | | | | | | | | | | Exploit the new api for userspace-controlled cmma. If supported, enable cmma during kvm initialization and register a reset handler for cmma, which is also called directly from the load IPL code. The reset functionality is needed to reset the cmma state of the guest pages, e.g. if a system reset is triggered via qemu monitor; otherwise this could result in data corruption. A guest triggered reboot may now lead to multiple cmma resets; this is OK, however, as this is slowpath anyway and the simplest way to achieve the intended effects.

* s390x/kvm: software breakpoint supportDavid Hildenbrand2014-05-201-3/+22
| | | | | | | | | | | | | | | | This patch allows to insert and remove sw breakpoints using the QEMU gdbserver on s390 as well as to interrupt execution on a breakpoint hit when running with KVM enabled. Whenever a software breakpoint is inserted, common code calls kvm ioctl KVM_UPDATE_GUEST_DEBUG. As this method's default on s390 is to return an error if not implement, the insertion will fail. Therefore, KVM also has to be updated in order to make use of software breakpoints.

* kvm: reset state from the CPU's reset methodPaolo Bonzini2014-05-133-2/+13
| | | | | | | | | | | | | | | | | | | Now that we have a CPU object with a reset method, it is better to keep the KVM reset close to the CPU reset. Using qemu_register_reset as we do now keeps them far apart. With this patch, PPC no longer calls the kvm_arch_ function, so it can get removed there. Other arches call it from their CPU reset handler, and the function gets an ARMCPU/X86CPU/S390CPU. Note that ARM- and s390-specific functions are called kvm_arm_* and kvm_s390_*, while x86-specific functions are called kvm_arch_*. That follows the convention used by the different architectures.
