2017-09-19s390x: allow cpu hotplug via device_addDavid Hildenbrand
E.g. the following now works: device_add host-s390-cpu,id=cpu1,core-id=1 The system will perform the same checks as when using cpu_add: - If the core_id is already in use - If the next sequential core_id isn't used - If core-id >= max_cpu is specified In addition, mixed CPU models are checked. E.g. if starting with -cpu host and trying to hotplug "qemu-s390-cpu": "Mixed CPU models are not supported on s390x."

2017-09-19target/s390x: use "core-id" for cpu number/address/id handlingDavid Hildenbrand
Some time ago we discussed that using "id" as property name is not the right thing to do, as it is a reserved property for other devices and will not work with device_add. Switch to the term "core-id" instead, and use it as an equivalent to "CPU address" mentioned in the PoP. There is no such thing as cpu number, so rename env.cpu_num to env.core_id. We use "core-id" as this is the common term to use for device_add later on (x86 and ppc). We can get rid of cpu->id now. Keep cpu_index and env->core_id in sync. cpu_index was already implicitly used by e.g. cpu_exists(), so keeping both in sync seems to be the right thing to do. cpu_index will now no longer automatically get set via cpu_exec_realizefn(). For now, we were lucky that both implicitly stayed in sync. Our new cpu property "core-id" can be a static property. Range checks can be avoided by using the correct type and the "setting after realized" check is done implicitly. device_add will later need the reserved "id" property. Hotplugging a CPU on s390x will then be: "device_add host-s390-cpu,id=cpu2,core-id=2".

2017-09-19s390x/pci: fixup ind_offset of msix routing entryYi Min Zhao
The guest uses the mpcifc instruction to register the aibvo of a zpci device, which is the starting offset of indicators in the indicator area and thus remains constant. Each msix vector is an offset from the aibvo. When we map a msix route to an adapter route, we should not modify the starting offset, but instead add the vector to the starting offset to get the absolute offset in the specific route.

2017-09-19Convert remaining error_report() to warn_report()Alistair Francis
In a previous patch (3dc6f8693694a649a9c83f1e2746565b47683923) we converted uses of error_report("warning:"... to use warn_report() instead. This was to help standardise on a single method of printing warnings to the user. There appears to have been some cases that slipped through in patch sets applied around the same time, this patch catches the few remaining cases. All of the warnings were changed using this command: find ./* -type f -exec sed -i \ 's|error_report(".*warning[,:] |warn_report("|Ig' {} + Indentation fixed up manually afterwards. Two messages were manually fixed up as well.

2017-09-01s390x: replace cpu_s390x_init() with cpu_generic_init()Igor Mammedov
cpu_s390x_init() is used only *-user targets indirectly via cpu_init() macro and has a hack to assign ids to created cpus (I'm not sure if 'id' really matters to *-user emulation). So to on safe side, instead of having custom wrapper to do numbering replace it with cpu_generic_init() and use S390CPUClass::next_cpu_id which could serve the same purpose as static variable and move cpu->id initialization to s390_cpu_initfn for CONFIG_USER_ONLY use-case. PS: ifdef is ugly but it allows us to hide s390x detail that isn't set by *-user targets and reuse generic cpu creation utility for btoh machine and user emulation.

2017-07-25s390x/css: fix ilen in IO instruction handlersHalil Pasic
When initiating a program check interruption by calling program_interrupt the instruction length (ilen) of the current instruction is supplied as the third parameter. On s390x all the IO instructions are of instruction format S and their ilen is 4. The calls to program_interrupt (introduced by commits 7b18aad543 ("s390: Add channel I/O instructions.", 2013-01-24) and 61bf0dcb2e ("s390x/ioinst: Add missing alignment checks for IO instructions", 2013-06-21)) however use ilen == 2. This is probably due to a confusion between ilen which specifies the instruction length in bytes and ILC which does the same but in halfwords. If kvm_enabled() this does not actually matter, because the ilen parameter of program_interrupt is effectively unused. Let's provide the correct ilen to program_interrupt.

2017-07-25target/s390x: Add remaining switches to compile with --disable-tcgThomas Huth
Adding some CONFIG_TCG tests to be finally able to compile QEMU on s390x also without TCG. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Thomas Huth <thuth@redhat.com> Message-Id: <1500886370-14572-6-git-send-email-thuth@redhat.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>
2017-07-25target/s390x: Move exception-related functions to a new excp_helper.c fileThomas Huth
These functions can not be compiled with --disable-tcg. But since we need the other functions from helper.c in the non-tcg build, we can also not simply remove helper.c from the non-tcg builds. Thus the problematic functions have to be moved into a separate new file instead that we can later omit in the non-tcg builds.

2017-07-25target/s390x: Rework program_interrupt() and related functionsThomas Huth
misc_helper.c won't be compiled with --disable-tcg anymore, but we still need the program_interrupt() function in that case. Move it to interrupt.c instead, and refactor it to re-use the code from trigger_pgm_exception() (for TCG) and enter_pgmcheck() (for KVM, which now got renamed to kvm_s390_program_interrupt() for clarity).

2017-07-25target/s390x: Move s390_cpu_dump_state() to helper.cThomas Huth
translate.c can not be compiled with --disable-tcg, but we need the s390_cpu_dump_state() in KVM-only builds, too. So let's move that function to helper.c instead, which will also be compiled when --disable-tcg has been specified.

2017-07-25target/s390x: improve baselining if certain base features are missingDavid Hildenbrand
There are certain features that we put into base models, but that are not relevant for the actual search. The most famous example are MSA subfunctions that might be disabled on certain real hardware out there. While the kvm host model detection will usually detect the correct model on such machines (as it will in the common case not pass features to check for into s390_find_cpu_def()), baselining will fall back to a quite old model just because some MSA subfunctions are missing. Let's improve that by ignoring lack of these features while performing the search for a base model.
