2017-07-14s390x/cpumodel: add zpci, aen and ais facilitiesYi Min Zhao3-4/+5
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.

2017-07-14s390x/css: add missing css state conditionallyHalil Pasic2-0/+94
Although we have recently vmstatified the migration of some css infrastructure, for some css entities there is still state to be migrated left, because the focus was keeping migration stream compatibility (that is basically everything as-is). 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 Pasic1-0/+13
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'.

Let's introduce a specialized way to inject adapter interrupts that, unlike the common interrupt injection method, allows to take the characteristics of the adapter into account. For adapters subject to AIS facility: - for non-kvm case, we handle the suppression for a given ISC in QEMU. - for kvm case, we pass adapter id to kvm to do airq injection.

2017-07-14s390x/flic: introduce modify_ais_mode callbackFei Li2-1/+72
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>

2017-07-13xilinx: Fix latent error handling bugEduardo Habkost2-6/+2
Assigning directly to *errp is not valid, as errp may be null, &error_fatal, or &error_abort. The !*errp conditional protects against the latter two, but we then leak @local_err. Fortunately, the qdev core always passes pointer to null, so this is "merely" a latent bug. Use error_propagate() instead. Cc: "Edgar E.

2017-07-11mips/malta: load the initrd at the end of the low memoryAurelien Jarno1-2/+3
Currently the malta board is loading the initrd just after the kernel. This doesn't work for kaslr enabled kernels, as the initrd ends-up being overwritten. Move the initrd at the end of the low memory, that should leave a sufficient gap for kaslr.
