2016-03-01tcg: Add type for vCPU pointersLluís Vilanova
Adds the 'TCGv_env' type for pointers to 'CPUArchState' objects. The tracing infrastructure later needs to differentiate between regular pointers and pointers to vCPUs. Also changes all targets to use the new 'TCGv_env' type instead of the generic 'TCGv_ptr'. As of now, the change is merely cosmetic ('TCGv_env' translates into 'TCGv_ptr'), but that could change in the future to enforce the difference. Note that a 'TCGv_env' type (for 'CPUState') is not added, since all helpers currently receive the architecture-specific pointer ('CPUArchState').

2016-01-27gdb: provide the name of the architecture in the target.xmlDavid Hildenbrand
This patch provides the name of the architecture in the target.xml if available. This allows the remote gdb to detect the target architecture on its own - so there is no need to specify it manually (e.g. if gdb is started without a binary) using "set arch *arch_name*". The name of the architecture is provided by a callback that can be implemented by all architectures. The arm implementation has special handling for iwmmxt and returns arm otherwise.

2016-01-27s390x: fix generation of event information crwSong Shan Gong
Only one channel report word (crw) may be pending if there is event-information pending. This patch introduces a bool-type field 'sei_pending' for the channel subsystem, which indicates whether there are pending events. It is set when event information is made pending and the crw generated, and cleared after the guest has collected all pending event information.

2015-10-09qdev: Protect device-list-properties against broken devicesMarkus Armbruster
Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef52358 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.

2015-10-02s390x: rename io_subsystem_reset -> subsystem_resetDavid Hildenbrand
According to the Pop: "Subsystem reset operates only on those elements in the configuration which are not CPUs". As this is what we actually do, let's simply rename the function.

2015-09-25s390: Remove ELF_MACHINE from cpu.hPeter Crosthwaite
The bootloader can just pass EM_S390 directly, as that is architecture specific code. This removes another architecture specific definition from the global namespace.

2015-09-11tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt
This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.
