2013-04-08hw: move char devices to hw/char/, configure via default-configs/Paolo Bonzini
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-01hw: include hw header files with full pathsPaolo Bonzini
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2013-03-01hw: move qdev-monitor.o to toplevel directoryPaolo Bonzini

Remove it from the hw/ directory and remove hw/qdev-monitor.h from hw/qdev.h too; this requires some files to have some new explicitly includes. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-02-13s390: Fix handling of iscs.Cornelia Huck
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: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>

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().

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

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.
