2016-05-19s390x: reorganize CSS bits between cpu.h and other headersPaolo Bonzini
Move cpu_inject_* to the only C file where they are used. Move ioinst.h declarations that need S390CPU to cpu.h, to make ioinst.h independent of cpu.h. Move channel declarations that only need SubchDev from cpu.h to css.h, to make more channel users independent of cpu.h.

2016-03-01s390x: remove {kvm_}s390_virtio_irq()Cornelia Huck
This interface was only used by the old virtio machine and therefore is not needed anymore. Reviewed-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Reviewed-by: Halil Pasic <pasic@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
2016-01-29s390: Clean up includesPeter Maydell
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

2014-11-05s390x: Fix sclp console inputAlexander Graf
When injecting an sclp console interrupt into the guest, we increase the PC by 4 for some reason. I have no idea why I put that code there, but it's clearly wrong. Remove the increment. This patch fixes sclp serial input for the ccw machine. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

2014-06-10s390x: consolidate floating interruptsCornelia Huck
Move the injection code for all floating interrupts to interrupt.c and add a comment. Also get rid of the #ifdef CONFIG_KVM for the service interrupt. Reviewed-by: Thomas Huth <thuth@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
2013-02-01target-s390x: Clean up cpu_inject_*() signaturesAndreas Färber
Despite cautioning that S390CPU is needed for upcoming CPUState refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (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().

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>
