First target-arm pullreq of the 4.0 series; most of this is Mao's cleanups that finally let us drop sysbus::init; the most interesting user-visible feature is RTH's patches adding some v8.1 and v8.2 architecture features. thanks -- PMM The following changes since commit 6145a6d84b3bf0f25935b88543febe076c61b0f4: Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20181212' into staging (2018-12-13 13:06:09 +0000) are available in the Git repository at: https://git.linaro.org/people/pmaydell/qemu-arm.git tags/pull-target-arm-20181213 for you to fetch changes up to 2d7137c10fafefe40a0a049ff8a7bd78b66e661f: target/arm: Implement the ARMv8.1-LOR extension (2018-12-13 14:41:24 +0000) ---------------------------------------------------------------- target-arm queue: * Convert various devices from sysbus init to instance_init * Remove the now unused sysbus init support entirely * Allow AArch64 processors to boot from a kernel placed over 4GB * hw: arm: musicpal: drop TYPE_WM8750 in object_property_set_link() * versal: minor fixes to virtio-mmio instantation * arm: Implement the ARMv8.1-HPD extension * arm: Implement the ARMv8.2-AA32HPD extension * arm: Implement the ARMv8.1-LOR extension (as the trivial "no limited ordering regions provided" minimum) ---------------------------------------------------------------- Edgar E.

We weren't doing this, which meant GDB treated our M-profile cores like A-profile ones. This mostly doesn't matter, but for instance means that it doesn't correctly handle backtraces where an M-profile exception frame is involved. Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile cores. The integer registers have the same offsets as the arm-core.xml, but register 25 is the M-profile XPSR rather than the A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and arm_cpu_gdb_write_register() to handle XSPR reads and writes.

They match up with the GVecGen2iFn typedef. Add out-of-line helpers. We got away with only having inline expanders because the neon vector size is only 16 bytes, and we know that the inline expansion will always succeed. When we reuse this for SVE, tcg-gvec-op may decide to use an out-of-line helper due to longer vector lengths.

Now it only supports ARMv8 SEA, a type of Generic Hardware Error Source version 2(GHESv2) error source. Afterwards, we can extend the supported types if needed. For the CPER section, currently it is memory section because kernel mainly wants userspace to handle the memory errors. This patch follows the spec ACPI 6.2 to build the Hardware Error Source table. For more detailed information, please refer to document: docs/specs/acpi_hest_ghes.rst build_ghes_hw_error_notification() helper will help to add Hardware Error Notification to ACPI tables without using packed C structures and avoid endianness issues as API doesn't need explicit conversion.

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.

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().
