2017-07-14s390x/cpumodel: wire up new hardware featuresJason J. Herne
Some new guest features have been introduced recently. Let's wire them up in the CPU model. Signed-off-by: Jason J.

2017-07-14s390x/flic: migrate ais statesYi Min Zhao
During migration we should transfer ais states to the target guest. This patch introduces a subsection to kvm_s390_flic_vmstate and new vmsd for qemu_flic. The ais states need to be migrated only when ais is supported.

2017-07-14s390x/cpumodel: add zpci, aen and ais facilitiesYi Min Zhao
zPCI instructions and facilities are available since IBM zEnterprise EC12. To support z/PCI in QEMU we enable zpci, aen and ais facilities starting with zEC12 GA1. And we always set zpci and aen bits in max cpu model. Later they might be switched off due to applied real cpu model. For ais bit, we only provide it in the full cpu model beginning with zEC12 and defer its enablement in the default cpu model to a later point in time. At the same time, disable them for 2.9 and older machines. Because of introducing AIS facility, we could check if it's enabled to initialize flic->ais_supported with the real value.

2017-07-14pc-bios/s390: add s390-netboot.imgChristian Borntraeger
It's already possible to do a network boot of an s390x guest with an external netboot image based on a Linux installation, but it would be much more convenient if the s390-ccw firmware supported network booting right out of the box, without the need to assemble such an external image first. This is an s390-netboot.img that can be used for network booting. You can download a combined kernel + initrd image via TFTP by starting QEMU for example with: qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \ -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img Note that this version does not support downloading via config files (i.e. pxelinux config files or .INS config files) yet. This will be added later. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>

Let us add vmstate helpers and extend existing vmstate descriptions so that we have everything we need. Let us guard the added state via css_migration_enabled, so we keep the compatible behavior if css migration is disabled.

2017-07-14s390x: add css_migration_enabled to machine classHalil Pasic
Currently the migration of the channel subsystem (css) is only partial and is done by the virtio ccw proxies -- the only migratable css devices existing at the moment. With the current work on emulated and passthrough devices we need to decouple the migration of the channel subsystem state from virtio ccw, and have a separate section for it. A new section however necessarily breaks the migration compatibility. So let us introduce a switch at the machine class, and put it in 'off' state for now. We will turn the switch 'on' for future machines once all preparations are met. For compatibility machines the switch will stay 'off'.

2017-07-14s390x/flic: introduce modify_ais_mode callbackFei Li
In order to emulate the adapter interruption suppression (AIS) facility properly, the guest needs to be able to modify the AIS mask. Interrupt suppression will be handled via the flic (for kvm, via a recently introduced kernel backend; for !kvm, in the flic code), so let's introduce a method to change the mode via the flic interface. We introduce the 'simm' and 'nimm' fields to QEMUS390FLICState to store interruption modes for each ISC. Each bit in 'simm' and 'nimm' targets one ISC, and collaboratively indicate three modes: ALL-Interruptions, SINGLE-Interruption and NO-Interruptions. This interface can initiate most transitions between the states; transition from SINGLE-Interruption to NO-Interruptions via adapter interrupt injection will be introduced in a following patch. The meaningful combinations are as follows: interruption mode | simm bit | nimm bit ------------------|----------|---------- ALL | 0 | 0 SINGLE | 1 | 0 NO | 1 | 1 Co-authored-by: Yi Min Zhao <zyimin@linux.vnet.ibm.com> Signed-off-by: Yi Min Zhao <zyimin@linux.vnet.ibm.com> Signed-off-by: Fei Li <sherrylf@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>

2017-07-14qom: enforce readonly nature of link's check callbackIgor Mammedov
link's check callback is supposed to verify/permit setting it, however currently nothing restricts it from misusing it and modifying target object from within. Make sure that readonly semantics are checked by compiler to prevent callback's misuse.

2017-07-14translate-all: remove redundant !tcg_enabled check in dump_exec_infoEmilio G. Cota
This check is redundant because it is already performed by the only caller of dump_exec_info -- the caller was updated by b7da97eef ("monitor: Check whether TCG is enabled before running the "info jit" code"). Checking twice wouldn't necessarily be too bad, but here the check also returns with tb_lock held. So we can either do the check before tb_lock is acquired, or just get rid of it. Given that it is redundant, I am going for the latter option. Signed-off-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-07-14vl: fix breakage of -tb-sizeEmilio G. Cota
Commit e7b161d573 ("vl: add tcg_enabled() for tcg related code") adds a check to exit the program when !tcg_enabled() while parsing the -tb-size flag. It turns out that when the -tb-size flag is evaluated, tcg_enabled() can only return 0, since it is set (or not) much later by configure_accelerator(). Fix it by unconditionally exiting if the flag is passed to a QEMU binary built with !CONFIG_TCG. Signed-off-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
