With the next patch, the memory API will complain if the TARGET_PHYS_ADDR_SPACE_BITS gets dangerously close to an overflow. s390x can handle up to 64 bit of physical address space from its page tables, but we never use that much. Just decrease the value. Cc: Alexander Graf <agraf@suse.de> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

We want to avoid expensive register synchronization IOCTL's on the hot path so a new kvm_s390_get_registers_partial() is introduced as a compliment to kvm_arch_get_registers(). The new function is called on the hot path, and kvm_arch_get_registers() is called when we need the complete runtime register state. kvm_arch_put_registers() is updated to only sync the partial runtime set when we've only dirtied the partial runtime set. This is to avoid sending bad data back to KVM if we've only partially synced the runtime register set. Signed-off-by: NJason J.

There are two ways to express an interruption subclass: - As a bitmask, as used in cr6. - As a number, as used in the I/O interruption word. Unfortunately, we have treated to I/O interruption word as if it contained the bitmask as well, which went unnoticed so far as - (queued-for-next) kvm made the same mistake, and - Linux guest kernels don't check the isc value in the I/O interruption word for subchannel interrupts. Make sure that we treat the I/O interruption word correctly. Signed-off-by: NCornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: NAlexander Graf <agraf@suse.de>

Despite cautioning that S390CPU is needed for upcoming CPUState refactorings, commit 5d69c547 (s390: I/O interrupt and machine check injection.) added functions cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument, claiming consistency with cpu_inject_ext(). This complicates making cpu_interrupt() take a CPUState even more and it required to pass &cpu->env from some S390CPU-aware call sites already, creating inconsistency elsewhere. Address that. This also eliminates the need for CPUS390XState in s390_virtio_irq().

The function is only used in misc_helper.c, so move it to that file. This reduces the size of debug executables (compiled without optimization) because they get unused code and data for each compilation which includes cpu.h. Executables with optimization don't change their size. ebcdic2ascii is currently unused and could be removed (not done here). The array ascii2ebcdic must be accessed with an unsigned index, therefore (int)ascii[i] was replaced by (uint8_t)ascii[i]. The old code would have failed for a signed char less than 0. The current code only converts "QEMU" and spaces to EBCDIC, so there is no problem today. Signed-off-by: NStefan Weil <sw@weilnetz.de> Signed-off-by: NAlexander Graf <agraf@suse.de>

This enables qemu -cpu help to return a list of supported CPU models on s390 and also to query for cpu definitions in the monitor. Initially only cpu model = host is returned.
