This is fine with our current implementation, but is a bit odd, because generally reset is supposed to be idempotent, and doesn't fit well in a three-phase-reset world where a resettable object will get multiple callbacks as the system is reset. We now have only one user of qemu_register_reset() which makes use of the ability to unregister itself within the callback: restore_boot_order(). We want to change our implementation of qemu_register_reset() to something where it would be awkward to maintain the "can self-unregister" feature. Rather than making that reimplementation complicated, change restore_boot_order() so that it doesn't unregister itself but instead returns doing nothing for any calls after it has done the "restore the boot order" work.

This is a subclass of Object, and it implements the Resettable interface. The container holds a list of arbitrary other objects which implement Resettable, and when the container is reset, all the objects it contains are also reset. This will allow us to have a 3-phase-reset equivalent of the old qemu_register_reset() API: we will have a single "simulation reset" top level ResetContainer, and objects in it are the equivalent of the old QEMUResetHandler functions. The qemu_register_reset() API manages its list of callbacks using a QTAILQ, but here we use a GPtrArray for our list of Resettable children: we expect the "remove" operation (which will need to do an iteration through the list) to be fairly uncommon, and we get simpler code with fewer memory allocations. Since there is currently no listed owner in MAINTAINERS for the existing reset-related source files, create a new section for them, and add these new files there also.

We define a new LegacyReset object which implements Resettable and defines its reset hold phase method to call a QEMUResetHandler function. When qemu_register_reset() is called, we create a new LegacyReset object and add it to the simulation_reset ResettableContainer. When qemu_unregister_reset() is called, we find the LegacyReset object in the container and remove it. This implementation of qemu_unregister_reset() means we'll end up scanning the ResetContainer's list of child objects twice, once to find the LegacyReset object, and once in g_ptr_array_remove(). In theory we could avoid this by having the ResettableContainer interface include a resettable_container_remove_with_equal_func() that took a callback method so that we could use g_ptr_array_find_with_equal_func() and g_ptr_array_remove_index(). But we don't expect qemu_unregister_reset() to be called frequently or in hot paths, and we expect the simulation_reset container to usually not have many children.

This is a behaviour change: because qemu_register_resettable() is aware of three-phase reset, this now means that: * 'enter' phase reset methods of devices and buses are called before any legacy reset callbacks registered with qemu_register_reset() * 'exit' phase reset methods of devices and buses are called after any legacy qemu_register_reset() callbacks Put another way, a qemu_register_reset() callback is now correctly ordered in the 'hold' phase along with any other 'hold' phase methods. The motivation for doing this is that we will now be able to resolve some reset-ordering issues using the three-phase mechanism, because the 'exit' phase is always after the 'hold' phase, even when the 'hold' phase function was registered with qemu_register_reset().

The typical +flow is: + +1. Code which wishes to reset the entire system does so by calling + ``qemu_system_reset_request()``. This schedules a reset, but the + reset will happen asynchronously after the function returns. + That makes this safe to call from, for example, device models. + +2. The function which is called to make the reset happen is + ``qemu_system_reset()``. Generally only core system code should + call this directly. + +3. ``qemu_system_reset()`` calls the ``MachineClass::reset`` method of + the current machine, if it has one. That method must call + ``qemu_devices_reset()``. If the machine has no reset method, + ``qemu_system_reset()`` calls ``qemu_devices_reset()`` directly. + +4. ``qemu_devices_reset()`` performs a reset of the system, using + the three-phase mechanism listed above. It resets all objects + that were registered with it using ``qemu_register_resettable()``. + It also calls all the functions registered with it using + ``qemu_register_reset()``. Those functions are called during the + "hold" phase of this reset. + +5. The most important object that this reset resets is the + 'sysbus' bus. The sysbus bus is the root of the qbus tree. This + means that all devices on the sysbus are reset, and all their + child buses, and all the devices on those child buses. + +6. Devices which are not on the qbus tree are *not* automatically + reset! (The most obvious example of this is CPU objects, but + anything that directly inherits from ``TYPE_OBJECT`` or ``TYPE_DEVICE`` + rather than from ``TYPE_SYS_BUS_DEVICE`` or some other plugs-into-a-bus + type will be in this category.) You need to therefore arrange for these + to be reset in some other way (e.g. using ``qemu_register_resettable()`` + or ``qemu_register_reset()``). -- 2.34.1 From: Sergey Kambalin <serg.oker@gmail.com> Pre setup for BCM2838 introduction Signed-off-by: Sergey Kambalin <sergey.kambalin@auriga.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20240226000259.2752893-2-sergey.kambalin@auriga.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- include/hw/arm/bcm2836.h | 26 +++++++++- hw/arm/bcm2836.c | 103 ++++++++++++++++++++++----------------- hw/arm/raspi.c | 2 +- 3 files changed, 84 insertions(+), 47 deletions(-) diff --git a/include/hw/arm/bcm2836.h b/include/hw/arm/bcm2836.h index XXXXXXX..XXXXXXX 100644 --- a/include/hw/arm/bcm2836.h +++ b/include/hw/arm/bcm2836.h @@ -XXX,XX +XXX,XX @@ #include "target/arm/cpu.h" #include "qom/object.h" +#define TYPE_BCM283X_BASE "bcm283x-base" +OBJECT_DECLARE_TYPE(BCM283XBaseState, BCM283XBaseClass, BCM283X_BASE) #define TYPE_BCM283X "bcm283x" -OBJECT_DECLARE_TYPE(BCM283XState, BCM283XClass, BCM283X) +OBJECT_DECLARE_SIMPLE_TYPE(BCM283XState, BCM283X) #define BCM283X_NCPUS 4 @@ -XXX,XX +XXX,XX @@ OBJECT_DECLARE_TYPE(BCM283XState, BCM283XClass, BCM283X) #define TYPE_BCM2836 "bcm2836" #define TYPE_BCM2837 "bcm2837" -struct BCM283XState { +struct BCM283XBaseState { /*< private >*/ DeviceState parent_obj;

That in turn means that tests of cpu_isar_feature(aa64_something, cpu) will return true. Until now we have had a design policy that you shouldn't check an aa64_ feature unless you know that the CPU has AArch64; but this is quite fragile as it's easy to forget and only causes a problem in the corner case where AArch64 was turned off. In particular, when we extend the ability to disable AArch64 from only KVM to also TCG there are many more aa64 feature check points which we would otherwise have to audit for whether they needed to be guarded with a check on ARM_FEATURE_AARCH64. Instead, make the CPU realize function zero out all the 64-bit ID registers if a TCG CPU doesn't have AArch64; this will make aa64_ feature tests generally return false. We only do this for TCG because only TCG really needs it, and for KVM it might be confusing to have QEMU's idea of the ID registers be different from KVM's.

The tolerance applies to a given cpreg kvm index, and can be of different types: a) mismatch in cpreg indexes - ToleranceNotOnBothEnds (cpreg index is allowed to be only present on one end) - ToleranceOnlySrcTestValue (cpreg index is allowed to be only present in source if its value @mask field matches @value) b) mismatch in cpreg values - ToleranceDiffInMask (value differences are allowed only within a mask) - ToleranceFieldLT (incoming field value must be less than a given value) - ToleranceFieldGT (incoming field value must be greater than a given value) A QLIST of such tolerances can be populated using a new helper: arm_register_cpreg_mig_tolerance() and arm_cpu_match_cpreg_mig_tolerance() allows to check whether a tolerance exists for a given kvm index and its criterion is matched. callers for those helpers will be introduced in subsequent patches. Only registration of migration tolerances related to cpreg index mismatch is currently allowed.

QEMU 11.0 was the last version that sent the + * bogus encoding, so this workaround can be removed at the point + * where we no longer care about migration from that version + * (i.e. when we remove the "virt-11.0" machine type). + */ + arm_register_cpreg_mig_tolerance(cpu, dbgtr_el0_kvmidx, + 0, 0, ToleranceNotOnBothEnds); } else { define_arm_cp_regs(cpu, not_v7_cp_reginfo); } -- 2.43.0 From: Eric Auger <eric.auger@redhat.com> This reverts commit 4f2b82f60431 ("target/arm: Reinstate bogus AArch32 DBGDTRTX register for migration compat).
