2012-10-29s390: sclp base supportHeinz Graalfs
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.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr.

2012-08-15s390: provide interface for service interrupt/introduce interrupt.cChristian Borntraeger
This patch creates interrupt.c. The first user is a callback for hw/* code to trigger an service interrupt for a given sccb value. Several interrupt types for s390 are floating (can be delivered to all CPUs). so this code does not belong to a specific CPU. Other interrupts (like the virtio one) are also floating and can be moved here later on. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-08-15s390: Fix error handling and condition code of service callChristian Borntraeger
Invalid sccb addresses will cause specification or addressing exception. Lets add those checks. Furthermore, the good case (cc=0) was incorrect for KVM, we did not set the CC at all. We now use return codes < 0 as program checks and return codes > 0 as condition code values.

2012-07-10s390: autodetect map privateChristian Borntraeger
By default qemu will use MAP_PRIVATE for guest pages. This will write protect pages and thus break on s390 systems that dont support this feature. Therefore qemu has a hack to always use MAP_SHARED for s390. But MAP_SHARED has other problems (no dirty pages tracking, a lot more swap overhead etc.) Newer systems allow the distinction via KVM_CAP_S390_COW. With this feature qemu can use the standard qemu alloc if available, otherwise it will use the old s390 hack.

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.
