* migration, vl: start migration via qmp_migrate_incomingPaolo Bonzini2020-12-101-1/+0Star
| | | | | | | | | | | | | | | Make qemu_start_incoming_migration local to migration/migration.c. By using the runstate instead of a separate flag, vl need not do anything to setup deferred incoming migration. qmp_migrate_incoming also does not need the deferred_incoming flag anymore, because "-incoming PROTOCOL" will clear the "once" flag before the main loop starts. Therefore, later invocations of the migrate-incoming command will fail with the existing "The incoming migration has already been started" error message.

* qemu-option: restrict qemu_opts_set to merge-lists QemuOptsPaolo Bonzini2020-12-101-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qemu_opts_set is used to create default network backends and to parse sugar options -kernel, -initrd, -append, -bios and -dtb. These are very different uses: I would *expect* a function named qemu_opts_set to set an option in a merge-lists QemuOptsList, such as -kernel, and possibly to set an option in a non-merge-lists QemuOptsList with non-NULL id, similar to -set. However, it wouldn't *work* to use qemu_opts_set for the latter because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the (QemuOptsList, id) pair already exists) are debatable. On the other hand, I would not expect qemu_opts_set to create a non-merge-lists QemuOpts with a single option; which it does, though. For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set hardly adds value over qemu_opts_parse. It does skip some parsing and unescaping, but that's not needed when creating default network backends. So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList if id is non-NULL, and it's mostly pointless if id is NULL. My solution to keeping the API as simple as possible is to limit qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we don't want comma-unescaping for -kernel) *and* has sane semantics. Network backend creation is switched to qemu_opts_parse. qemu_opts_set is now only used on merge-lists QemuOptsList... except in the testcase, which is changed to use a merge-list QemuOptsList. With this change we can also remove the id parameter. With the parameter always NULL, we know that qemu_opts_create cannot fail and can pass &error_abort to it.

| | | | | | | | | | | | | | | | | | | | The IOAPIC has an 'Extended Destination ID' field in its RTE, which maps to bits 11-4 of the MSI address. Since those address bits fall within a given 4KiB page they were historically non-trivial to use on real hardware. The Intel IOMMU uses the lowest bit to indicate a remappable format MSI, and then the remaining 7 bits are part of the index. Where the remappable format bit isn't set, we can actually use the other seven to allow external (IOAPIC and MSI) interrupts to reach up to 32768 CPUs instead of just the 255 permitted on bare metal.

* | hw/intc/armv7m_nvic: Implement read/write for RAS register blockPeter Maydell2020-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RAS feature has a block of memory-mapped registers at offset 0x5000 within the PPB. For a "minimal RAS" implementation we provide no error records and so the only registers that exist in the block are ERRIIDR and ERRDEVID. The "RAZ/WI for privileged, BusFault for nonprivileged" behaviour of the "nvic-default" region is actually valid for minimal-RAS, so the main benefit of providing an explicit implementation of the register block is more accurate LOG_UNIMP messages, and a framework for where we could add a real RAS implementation later if necessary.

Within this large region, the range 0xe000e000 to 0xe000efff is the System Control Space (NVIC, system registers, systick) and 0xe002e000 to 0exe002efff is its Non-secure alias. The architecture is clear that within the SCS unimplemented registers should be RES0 for privileged accesses and generate BusFault for unprivileged accesses, and we currently implement this. It is less clear about how to handle accesses to unimplemented regions of the wider PPB. Unprivileged accesses should definitely cause BusFaults (R_DQQS), but the behaviour of privileged accesses is not given as a general rule. However, the register definitions of individual registers for components like the DWT all state that they are RES0 if the relevant component is not implemented, so the simplest way to provide that is to provide RAZ/WI for the whole range for privileged accesses. (The v7M Arm ARM does say that reserved registers should be UNK/SBZP.) Expand the container MemoryRegion that the NVIC exposes so that it covers the whole PPB space. This means: * moving the address that the ARMV7M device maps it to down by 0xe000 bytes * moving the off and the offsets within the container of all the subregions forward by 0xe000 bytes * adding a new default MemoryRegion that covers the whole container at a lower priority than anything else and which provides the RAZWI/BusFault behaviour Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20201119215617.29887-2-peter.maydell@linaro.org

|/ | | | | | | | | | | | | | | | | | | | | | | | | | The Xilinx ZynqMP CAN controller is developed based on SocketCAN, QEMU CAN bus implementation. Bus connection and socketCAN connection for each CAN module can be set through command lines. Example for using single CAN: -object can-bus,id=canbus0 \ -machine xlnx-zcu102.canbus0=canbus0 \ -object can-host-socketcan,id=socketcan0,if=vcan0,canbus=canbus0 Example for connecting both CAN to same virtual CAN on host machine: -object can-bus,id=canbus0 -object can-bus,id=canbus1 \ -machine xlnx-zcu102.canbus0=canbus0 \ -machine xlnx-zcu102.canbus1=canbus1 \ -object can-host-socketcan,id=socketcan0,if=vcan0,canbus=canbus0 \ -object can-host-socketcan,id=socketcan1,if=vcan0,canbus=canbus1 To create virtual CAN on the host machine, please check the QEMU CAN docs: https://github.com/qemu/qemu/blob/master/docs/can.txt Signed-off-by: Vikram Garhwal <fnu.vikram@xilinx.com> Message-id: 1605728926-352690-2-git-send-email-fnu.vikram@xilinx.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

* acpi: cpuhp: introduce 'firmware performs eject' status/control bitsIgor Mammedov2020-12-091-0/+1
| | | | | | | | | | | | | Adds bit #4 to status/control field of CPU hotplug MMIO interface. New bit will be used OSPM to mark CPUs as pending for removal by firmware, when it calls _EJ0 method on CPU device node. Later on, when firmware sees this bit set, it will perform CPU eject which will clear bit #4 as well.
