2020-05-15qom: Drop object_property_set_description() parameter @errpMarkus Armbruster
object_property_set_description() and object_class_property_set_description() fail only when property @name is not found. There are 85 calls of object_property_set_description() and object_class_property_set_description(). None of them can fail: * 84 immediately follow the creation of the property. * The one in spapr_rng_instance_init() refers to a property created in spapr_rng_class_init(), from spapr_rng_properties[]. Every one of them still gets to decide what to pass for @errp. 51 calls pass &error_abort, 32 calls pass NULL, one receives the error and propagates it to &error_abort, and one propagates it to &error_fatal. I'm actually surprised none of them violates the Error API. What are we gaining by letting callers handle the "property not found" error? Use when the property is not known to exist is simpler: you don't have to guard the call with a check. We haven't found such a use in 5+ years. Until we do, let's make life a bit simpler and drop the @errp parameter.

2020-05-15qom: Drop convenience method object_property_get_uint16List()Markus Armbruster
qom/object.c provides object_property_get_TYPE() and object_property_set_TYPE() for a number of common types. These are all convenience wrappers around object_property_get_qobject() and object_property_set_qobject(). Except for object_property_get_uint16List(), which is unusual in two ways: * It bypasses object_property_get_qobject(). Fixable; the previous commit did it for object_property_get_enum()) * It stores the value through a parameter. Its contract claims it returns the value, like the other functions do. Also fixable. Fixing is not worthwhile, though: object_property_get_uint16List() has seen exactly one user in six years. Convert the lone user to do its job with the generic object_property_get_qobject(), and drop object_property_get_uint16List().

2020-05-14target/arm: Convert Neon fp VMUL, VMLA, VMLS 3-reg-same insns to decodetreePeter Maydell
Convert the Neon integer VMUL, VMLA, and VMLS 3-reg-same inssn to decodetree. We don't have a gvec helper for multiply-accumulate, so VMLA and VMLS need a loop function do_3same_fp(). This takes a reads_vd parameter to do_3same_fp() which tells it to load the old value into vd before calling the callback function, in the same way that the do_vfp_3op_sp() and do_vfp_3op_dp() functions in translate-vfp.inc.c work. (The only uses in this patch pass reads_vd == true, but later commits will use reads_vd == false.) This conversion fixes in passing an underdecoding for VMUL (originally reported by Fredrik Strupe <fredrik@strupe.net>): bit 1 of the 'size' field must be 0. The old decoder didn't enforce this, but the decodetree pattern does. The gen_VMLA_fp_reg() function performs the addition operation with the operands in the opposite order to the old decoder: since Neon sets 'default NaN mode' float32_add operations are commutative so there is no behaviour difference, but putting them this way around matches the Arm ARM pseudocode and the required operation order for the subtraction in gen_VMLS_fp_reg().

2020-05-14target-arm: kvm64: handle SIGBUS signal from kernel or KVMDongjiu Geng
Add a SIGBUS signal handler. In this handler, it checks the SIGBUS type, translates the host VA delivered by host to guest PA, then fills this PA to guest APEI GHES memory, then notifies guest according to the SIGBUS type. When guest accesses the poisoned memory, it will generate a Synchronous External Abort(SEA). Then host kernel gets an APEI notification and calls memory_failure() to unmapped the affected page in stage 2, finally returns to guest. Guest continues to access the PG_hwpoison page, it will trap to KVM as stage2 fault, then a SIGBUS_MCEERR_AR synchronous signal is delivered to Qemu, Qemu records this error address into guest APEI GHES memory and notifes guest using Synchronous-External-Abort(SEA). In order to inject a vSEA, we introduce the kvm_inject_arm_sea() function in which we can setup the type of exception and the syndrome information. When switching to guest, the target vcpu will jump to the synchronous external abort vector table entry. The ESR_ELx.DFSC is set to synchronous external abort(0x10), and the ESR_ELx.FnV is set to not valid(0x1), which will tell guest that FAR is not valid and hold an UNKNOWN value. These values will be set to KVM register structures through KVM_SET_ONE_REG IOCTL.

2020-05-14target/arm: Pass pointer to qc to qrdmla/qrdmlsRichard Henderson
Pass a pointer directly to env->vfp.qc[0], rather than env. This will allow SVE2, which does not modify QC, to pass a pointer to dummy storage. Change the return type of inl_qrdml.h_s16 to match the sense of the operation: signed.

2020-05-14target/arm: Swap argument order for VSHL during decodeRichard Henderson
Rather than perform the argument swap during code generation, perform it during decode. This means it doesn't have to be special cased later, and we can share code with aarch64 code generation. Hopefully the decode comment addresses any confusion that might arise in between.
